NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

September 30, 2017

(unaudited)

ChemoCentryx, Inc. (the Company) commenced operations in 1997. The Company is a clinical-stage biopharmaceutical company focused on developing new medications targeted at inflammatory disorders, autoimmune diseases and cancer. The Company’s principal operations are in the United States and it operates in one segment.

Unaudited Interim Financial Information

The financial information filed is unaudited. The Condensed Consolidated Financial Statements included in this report reflect all adjustments (consisting only of normal recurring adjustments) that the Company considers necessary for the fair statement of the results of operations for the interim periods covered and of the financial condition of the Company at the date of the interim balance sheet. The December 31, 2016 Condensed Consolidated Balance Sheet was derived from audited financial statements. The results for interim periods are not necessarily indicative of the results for the entire year or any other interim period. The Condensed Consolidated Financial Statements should be read in conjunction with the Company’s financial statements and the notes thereto included in the Company’s annual report on Form 10-K for the year ended December 31, 2016 filed with the Securities and Exchange Commission on March 14, 2017.

Use of Estimates

The preparation of financial statements in conformity with generally accepted accounting principles in the United States of America (U.S. GAAP) requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from these estimates.

Concentration of Credit Risk

The Company invests in a variety of financial instruments and, by its policy, limits the amount of credit exposure with any one issuer, industry or geographic area.

Accounts receivable are typically unsecured and are concentrated in the pharmaceutical industry and government sector. Accordingly, the Company may be exposed to credit risk generally associated with pharmaceutical companies and government funded entities. The Company has not historically experienced any significant losses due to concentration of credit risk.

Accounts receivable consists of the following (in thousands):

As of December 31, 2016, accounts receivable excluded the $20.0 million cash commitment which is due from Vifor in December 2017 in connection with the CCX140 Agreement. See Note 7, “Collaboration and License Agreements” for a detailed discussion.

Net Loss Per Share

Basic net loss per common share is computed by dividing net loss attributable to common stockholders by the weighted-average number of common shares outstanding during the period, without consideration for common stock equivalents.

Diluted net loss per share is computed by dividing net loss attributable to common stockholders by the sum of the weighted-average number of common shares outstanding and dilutive common stock equivalent shares outstanding for the period. The Company’s potentially dilutive common stock equivalent shares, which include incremental common shares issuable upon (i) the exercise of outstanding stock options and warrants, (ii) vesting of restricted stock units (RSUs) and restricted stock awards (RSAs), and (iii) the purchase from contributions to the 2012 Employee Stock Purchase Plan (the ESPP), (calculated based on the treasury stock method), are only included in the calculation of diluted net loss per share when their effect is dilutive.

For the nine months ended September 30, 2017 and 2016, the following potentially dilutive securities were excluded from the calculation of diluted net loss per share due to their anti-dilutive effect:

Comprehensive Loss

Comprehensive loss comprises net loss and other comprehensive income (loss). For the periods presented other comprehensive income (loss) consists of unrealized gains and losses on the Company’s available-for-sale securities. For the three and nine months ended September 30, 2017 and 2016, there were no sales of investments, and therefore there were no reclassifications from accumulated other comprehensive loss to net loss.

Recent Accounting Pronouncements

In May 2014, the Financial Accounting Standard Board (FASB) issued Accounting Standards Update (ASU) No. 2014-09, Revenue from Contracts with Customers. The new standard’s core principle is that a reporting entity will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. On July 9, 2015, the FASB voted to delay the effective date of the new standard by one year. The standard would become effective for the Company beginning in the first quarter of 2018. Early application would be permitted in 2017. Entities would have the option of using either a full retrospective or a modified retrospective approach to adopt this new guidance. In 2016, the FASB updated the guidance for reporting revenue gross versus net to improve the implementation guidance on principal versus agent considerations, and for identifying performance obligations and the accounting of intellectual property licenses. In addition, the FASB introduced practical expedients and made narrow scope improvements to the new accounting guidance.

The Company currently plans to adopt the accounting standard update on January 1, 2018, using the modified retrospective approach. The cumulative effect of adopting the accounting standard update will be recorded to the Company’s accumulated deficit on January 1, 2018. The Company is currently analyzing its collaboration agreements to determine the differences in the accounting treatment under ASU No. 2014-09 compared to the current accounting treatment. During 2016, the Company entered into two license and collaboration agreements. The Company has primarily derived its revenues from license and collaboration agreements. The consideration the Company is eligible to receive under these agreements includes upfront payments, research and development funding, milestone payments, and royalties. Each license and collaboration agreement is unique and will need to be assessed separately under the five-step process under the new standard. The new revenue recognition standard differs from the current accounting standard in many respects, such as in the accounting for variable consideration and the measurement of progress toward completion of performance obligations. While the Company has not completed its ongoing assessment of the impact of adoption, the adoption of ASU No. 2014-09 may have a material effect on its financial statements.

In February 2016, the FASB issued ASU No. 2016-12, Leases (Topic 842). The new standard requires all lessees recognize the assets and liabilities that arise from leases on the balance sheet and disclose qualitative and quantitative information about its leasing arrangements. The new standard will be effective for the Company on January 1, 2019. The Company is currently evaluating the impact of the adoption of this standard on its financial statements. However, the Company expects the adoption of this accounting guidance to result in an increase in lease assets and a corresponding increase in lease liabilities on its balance sheets.

In March 2016, the FASB issued ASU No. 2016-09, Improvements to Employee Share-Based Payment Accounting, which is intended to simplify several aspects of the accounting for share-based payment award transactions, including the income tax consequences, an option to recognize gross stock compensation expense with actual forfeitures recognized as they occur, as well as certain classifications on the statement of cash flows. Under this guidance, on a prospective basis, companies will no longer record excess tax benefits and tax deficiencies from stock option exercises in additional paid-in capital (APIC). Instead, they will record all excess tax benefits and tax deficiencies as income tax expense or benefit in the statement of operations. In addition, the guidance eliminates the requirement that excess tax benefits be realized before companies can recognize them. The ASU requires a cumulative-effect adjustment for previously unrecognized excess tax benefits in opening retained earnings in the annual period of adoption. The Company adopted ASU No. 2016-09 on January 1, 2017. Upon adoption, the Company recognized the excess tax benefit balance of $2.1 million as of January 1, 2017 as a deferred tax asset with a corresponding increase to the Company’s deferred tax asset valuation allowance. Additionally, as provided for under this new guidance, the Company elected to continue to estimate forfeitures. The adoption of this aspect of the guidance did not have a material impact on the Company’s financial statements.

The amortized cost and fair value of cash equivalents and investments at September 30, 2017 and December 31, 2016 were as follows (in thousands):

Cash equivalents in the tables above exclude cash of $0.9 million and $2.3 million as of September 30, 2017 and December 31, 2016, respectively. All available-for-sale securities held as of September 30, 2017 had contractual maturities of less than two years. There have been no significant realized gains or losses on available-for-sale securities for the periods presented. No significant available-for-sale securities held as of September 30, 2017 have been in a continuous unrealized loss position for more than 12 months. As of September 30, 2017, unrealized losses on available-for-sale investments are not attributed to credit risk and are

considered to be temporary. The Company believes that it is more-likely-than-not that investments in an unrealized loss position will be held until maturity or the recovery of the cost basis of the investment. The Company believes it has no other-than-temporary impairments on its securities because it does not intend to sell these securities and it believes it is not more likely than not that it will be required to sell these securities before the recovery of their amortized cost basis. To date, the Company has not recorded any impairment charges on marketable securities related to other-than-temporary declines in market value.

The Company determines the fair value of financial assets and liabilities using three levels of inputs as follows:

Level 1—Inputs which include quoted prices in active markets for identical assets and liabilities.

Level 2—Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

The Company’s financial assets subject to fair value measurements on a recurring basis and the level of inputs used in such measurements are as follows (in thousands) as of September 30, 2017 and December 31, 2016:

During the nine months ended September 30, 2017, there were no transfers between Level 1 and Level 2 financial assets. When the Company uses observable market prices for identical securities that are traded in less active markets, the Company classifies its marketable debt instruments as Level 2. When observable market prices for identical securities are not available, the Company prices its marketable debt instruments using non-binding market consensus prices that are corroborated with observable market data; quoted market prices for similar instruments; or pricing models, such as a discounted cash flow model, with all significant inputs derived from or corroborated with observable market data. Non-binding market consensus prices are based on the proprietary valuation models of pricing providers or brokers. These valuation models incorporate a number of inputs, including non-binding and binding broker quotes; observable market prices for identical or similar securities; and the internal assumptions of pricing providers or brokers that use observable market inputs and, to a lesser degree, unobservable market inputs. The Company corroborates non-binding market consensus prices with observable market data using statistical models when observable market data exists. The discounted cash flow model uses observable market inputs, such as LIBOR-based yield curves, currency spot and forward rates, and credit ratings.

Accrued liabilities consist of the following (in thousands):

Bio-Techne Corporation, formerly Techne Corporation, is one of the Company’s principal stockholders. In connection with the Company’s initial public offering (IPO) in February 2012, Bio-Techne received a warrant with a ten-year term to purchase 150,000 shares of the Company’s common stock at an exercise price per share equal to $20.00 per share, or 200% of the IPO price of its common stock, which was outstanding as of September 30, 2017. The Company had an accounts payable balance due to Bio-Techne for the purchases of research materials of approximately $1,000 and $25,000 as of September 30, 2017 and December 31, 2016, respectively.

In May 2016, the Company entered into an exclusive collaboration and license agreement with Vifor (International) Ltd. (Vifor) pursuant to which the Company granted Vifor exclusive rights to commercialize avacopan in Europe and certain other markets (the Avacopan Agreement). Avacopan is the Company’s lead drug candidate for the treatment of patients with anti-neutrophil cytoplasmic auto-antibody associated vasculitis and other rare diseases. The Company retains control of ongoing and future development of avacopan (other than country-specific development in the licensed territories) and all commercialization rights to avacopan in the United States and China. The Avacopan Agreement also provided Vifor with an exclusive option to negotiate during 2016 a worldwide license agreement for one of the Company’s other drug candidates, CCX140, an orally administered inhibitor of the chemokine receptor known as CCR2.

In connection with the Avacopan Agreement, the Company received a non-refundable upfront payment of $85.0 million, comprising $60.0 million in cash and $25.0 million in the form of an equity investment to purchase 3,333,333 shares of the Company’s common stock at a price of $7.50 per share. The $85.0 million upfront consideration was initially allocated as of June 30, 2016 as follows:

Following the October 2016 expiration of the $12.5 million potentially creditable towards a CCX140 license agreement, such amount was reclassified to the amortizable portion of deferred revenue, which continues to be recognized over the estimated period of performance under the Avacopan Agreement ending in June 2020.

In February 2017, Vifor and the Company expanded the Vifor territories under the Avacopan Agreement to include all markets outside the United States and China (the Avacopan Amendment). The Company retains control of ongoing and future development of avacopan (other than country-specific development in the licensed territories), and all commercialization rights to avacopan in the United States and China. In connection with this arrangement, the Company received a $20.0 million upfront cash commitment for the expanded rights, $10.0 million of which was received in February 2017. The remaining $10.0 million is due in February 2018 and is not reflected in accounts receivable as of September 30, 2017. The February 2017 Avacopan Amendment and the original May 2016 Avacopan Agreement are accounted for as a combined agreement. The February 2017 Avacopan Amendment did not represent a material modification given among other factors, there were no changes to the Company’s deliverables under the arrangement. As such, the additional upfront commitment of $20.0 million under the Avacopan Amendment will be recognized over the remaining estimated period of performance ending in June 2020. For the three and nine months ended September 30, 2017, the Company recognized $6.2 million and $18.2 million, respectively, of collaboration and license revenue under the Avacopan Agreement and the Avacopan Amendment, compared to $4.1 million and $6.8 million in the same periods ended September 30, 2016. Upon achievement of certain regulatory and commercial milestones with avacopan, the Company will receive additional payments of up to $510.0 million under the Avacopan Agreement. In addition, the Company will receive royalties, with rates ranging from the low teens to the mid-twenties, on future potential net sales of avacopan by Vifor in the licensed territories.

In December 2016, the Company entered into a second collaboration and license agreement with Vifor pursuant to which the Company granted Vifor exclusive rights to commercialize CCX140 (the CCX140 Agreement) in markets outside the U.S. and China,. CCX140 is an orally-administered inhibitor of the chemokine receptor known as CCR2. The Company retains marketing rights in the U.S. and China, while Vifor has commercialization rights in the rest of the world. Pursuant to the CCX140 Agreement, the Company will be responsible for the clinical development of CCX140 in rare renal diseases and will be reimbursed for Vifor’s equal share of such development cost. Vifor retains an option to solely develop and commercialize CCX140 in more prevalent forms of chronic kidney disease (CKD). Should Vifor later exercise the CKD option, ChemoCentryx would receive co-promotion rights in CKD in the U.S.

Under the terms of the CCX140 Agreement, the Company received a non-refundable upfront commitment of $50.0 million, $30.0 million of which was received in January 2017. The remaining $20.0 million, which is due on the first anniversary of the CCX140 Agreement, was not reflected in accounts receivable as of September 30, 2017. The upfront commitment of $50.0 million will be recognized over the estimated period of performance under the CCX140 Agreement, which approximates 5.0 years, ending in December 2021. The deliverables under the CCX140 Agreement consist of intellectual property licenses, development and regulatory services for the submission of the MAA. The Company considered the provisions of the revenue recognition multiple-element arrangement guidance and concluded that the license and the development and regulatory activities for the submission of the MAA do not have stand-alone value because the rights conveyed to do not permit Vifor to perform all efforts necessary to use the Company’s technology to bring the compound through development and, upon regulatory approval, commercialization of the compound. Accordingly, the Company combined these deliverables and allocated the upfront consideration of $50.0 million into a single unit of accounting.

For the three and nine months ended September 30, 2017, the Company recognized $2.8 million and $8.0 million of collaboration and license revenue under the CCX140 Agreement, respectively, of which $2.5 million and $7.5 million were associated with the recognition of upfront commitment. The remaining amounts represented collaboration revenue derived from funding of CCX140 development services from Vifor. Upon achievement of certain regulatory and commercial milestones with CCX140, the Company will receive additional payments of up to $625.0 million under the CCX140 Agreement. In addition, the Company will receive tiered royalties, with rates ranging from ten to the mid-twenties, on net sales of CCX140 in the licensed territories.

Under the Avacopan Agreement and the CCX140 Agreement, the Company determined that future contingent payments related to regulatory milestones meet the definition of a substantive milestone under the accounting guidance. Accordingly, revenue for the achievement of these milestones will be recognized in the period when the milestone is achieved. The Company will be eligible to receive contingent payments related to commercial milestones based on the performance of Vifor and these payments are not considered to be milestones under the accounting guidance. These contingent commercial milestone payments will be included in the allocation of arrangement consideration if and when achieved, resulting in an accounting treatment similar to the upfront payment. As of September 30, 2017, the Company had not received any milestone payments under the Avacopan Agreement or the CCX140 Agreement. The Company expects to recognize royalty revenue in the period of sale of the related product, based on the underlying contract terms. The Avacopan Agreement and the CCX140 Agreement are accounted for as separate arrangements.

In April 2016, the Company was awarded an Orphan Products Development grant by the U.S. Food and Drug Administration to support the clinical development of avacopan in the amount of $500,000, which was fully recognized and received as of September 30, 2017. The term of the grant expired in May 2017. During the three and nine months ended September 30, 2017, the Company did not recognize any grant revenue. During the three and nine months ended September 30, 2016, the Company recognized $120,000 and $295,000, respectively, of grant revenue.

During the nine months ended September 30, 2017, the Company had the following option activities under its equity incentive plans:

Restricted Stock

During the nine months ended September 30, 2017, the activity for restricted stock is summarized as follows:

Stock-based Compensation

Total stock-based compensation expense was $1.9 million and $6.8 million during the three and nine months ended September 30, 2017, respectively, and $1.8 million and $6.5 million, respectively, during the same periods ended September 30, 2016. As of September 30, 2017, $9.6 million, $2.0 million, and $23,000 of total unrecognized compensation expenses associated with outstanding employee stock options, unvested restricted stock, and the ESPP, net of estimated forfeitures, were expected to be recognized over a weighted-average period of 2.52, 1.72, and 0.12 years, respectively.

Overview

ChemoCentryx is a biopharmaceutical company developing new medications targeted at inflammatory disorders, autoimmune diseases and cancer. Each of our drug candidates selectively blocks a specific chemokine or chemoattractant receptors, leaving the rest of the immune system intact. Our drug candidates are small molecules, which are orally administered, offering significant quality of life benefits, since patients swallow a capsule or pill instead of having to visit a clinic for an infusion or undergo an injection.

In 2016 we executed on our strategy to form an alliance with a partner that could provide upfront commitments and milestones to support the clinical development of our leading two drug candidates, avacopan and CCX140, to registration and pay us royalties upon sales in international markets, while we develop our own commercial infrastructure to sell directly in the United States.

To help us manage the wide array of opportunities, we have segmented our pipeline into early stage and late stage compounds.

Late Stage Compounds

We have chosen to focus initially on kidney disease, particularly on rare indications, where orphan drug candidates tend to enjoy a faster path to market and better reimbursement. Our leading drug candidates address areas of clear unmet need, where the current standard of care, or SOC, is insufficient to halt progression of the disease and/or where today’s treatment options come with serious side effects, such as those which accompany the prolonged use of steroids:

Avacopan (CCX168)—Complement Inhibition in Orphan and Rare Diseases

Avacopan (formerly CCX168) is an orally-administered complement inhibitor targeting the C5a receptor, or C5aR, and is being developed for orphan and rare diseases, including 1) anti-neutrophil cytoplasmic auto-antibody associated vasculitis, or AAV, a devastating autoimmune disease that destroys blood vessels and can lead to kidney failure; 2) atypical hemolytic uremic syndrome, or aHUS, a rare, life threatening disease; and 3) complement 3 glomerulopathy, or C3G, a debilitating kidney disease that can lead to kidney failure.

Avacopan has been granted orphan drug designation by the U.S. Food and Drug Administration, or FDA, for the treatment of AAV, aHUS and C3G and by the European Medicines Agency, or EMA, for the treatment of microscopic polyangiitis and granulomatosis with polyangiitis, both forms of AAV, and C3G. Additionally, avacopan has been granted PRIority MEdicines, or PRIME, designation from the EMA, to expedite its clinical development, and to potentially accelerate its marketing authorization.

Following completion of two Phase II clinical trials in patients with AAV, the results of which demonstrated that avacopan was safe, well-tolerated and provided effective steroid-free control of the disease, we launched the Phase III ADVOCATE trial in December 2016. The FDA and the EMA concurred with the design of the study. ADVOCATE is a randomized, double-blind two-arm study that is planned to enroll 300 patients at approximately 200 sites in the United States, Canada, Europe, Australia, and New Zealand. We expect to complete patient enrollment of the Phase III ADVOCATE trial in mid-2018. We recently launched a registration-supporting clinical trial to study avacopan for the treatment of patients with C3G and also plan to initiate the same for the treatment of patients with aHUS in 2017; designed to potentially support registration of avacopan in these indications.

CCX140—Chronic and Rare Kidney Diseases

CCX140 is an orally-administered inhibitor of the chemokine receptor known as CCR2, has been in development for diabetic nephropathy, or DN, a form of chronic kidney disease, or CKD, and is now being developed for focal segmental glomerulosclerosis, or FSGS, a rare renal disease characterized by progressive proteinuria—excess protein in the urine—and impaired renal function.

A Phase II clinical trial of CCX140 in patients with DN met its primary endpoint by demonstrating that CCX140 given orally once daily added to an SOC renin-angiotensin-aldosterone system inhibitor treatment resulted in a statistically significant reduction in proteinuria, beyond that achieved with SOC alone. Based on the safety and efficacy data related to reduction in proteinuria observed in the Phase II trial in DN, we plan to initiate in 2017 a clinical endpoint trial of CCX140 for the treatment of patients with FSGS, for which there are currently no FDA-approved treatments.

Global Kidney Health Alliance with Vifor

In May 2016 we announced a partnership with Vifor (International) Ltd., or Vifor, a European-based world leader specializing in kidney disease, for the commercial rights to avacopan in Europe and certain other international markets, which we refer to as the Avacopan Agreement. We expanded our partnership with Vifor in December 2016 with an additional deal for our other late stage drug candidate, CCX140, whereby we granted Vifor worldwide rights outside of the United States and China, which we refer to as the CCX140 Agreement; and in February 2017, we announced a further deal with Vifor for avacopan that harmonized the geographic commercialization rights underlying the agreements for both drug candidates, which we refer to as the Avacopan Amendment.

We have secured $155 million in upfront cash payments and commitments, plus substantial potential milestone payments pursuant to our agreements with Vifor. Through our alliance, we maintain the commercial rights of avacopan and CCX140 in the United States and China, and also retain control of the clinical development programs for rare renal disease. Vifor gains the commercial rights for all other international markets, and will pay us tiered royalties, with rates ranging from ten to the mid-twenties, on potential net sales.

At a future time defined in the contract, Vifor has an option to solely develop and commercialize CCX140 in more prevalent forms of CKD. Should Vifor later exercise the CKD option, we would receive co-promotion rights for CKD in the United States, and we estimate that the clinical development and registration process for CKD would end at approximately the same time as Orphan Drug exclusivity.

Early Stage Compounds

While the science has led us to focus initially on kidney disease, our targeted blocking system designed to stop the spread of inflammatory disease-inducing cells shows promise in other disease areas. Over time we plan to bring forward drug candidates to treat other inflammatory and autoimmune disorders, as well as cancer, where our drug candidate CCX872 has shown promise in a Phase I trial for non-operable pancreatic cancer. Our ability to do so will grow as we increase our scale and start to earn revenues and royalties from the commercialization of our late stage kidney disease franchise.

Since commencing our operations in 1997, our efforts have focused on research, development and the advancement of our drug candidates into and through clinical trials. As a result, we have incurred significant losses. We have funded our operations primarily through the sale of convertible preferred and common stock, revenue under our collaborations, government contracts and grants and borrowings under equipment financing arrangements.

As of September 30, 2017, we had an accumulated deficit of $328.9 million. We expect to continue to incur net losses as we develop our drug candidates, expand clinical trials for our drug candidates currently in clinical development, expand our research and development activities, expand our systems and facilities, seek regulatory approvals and engage in commercialization preparation activities in anticipation of FDA approval of our drug candidates. In addition, if a product is approved for commercialization, we will need to expand our organization. Significant capital is required to launch a product and many expenses are incurred before revenues are received. We are unable to predict the extent of any future losses or when we will become profitable, if at all.

JOBS Act

In April 2012, the JOBS Act was enacted. Section 107 of the JOBS Act provides that an emerging growth company can utilize the extended transition period provided in Section 7(a)(2)(B) of the Securities Act for implementing new or revised accounting standards. In other words, an emerging growth company can delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. We have elected to delay such adoption of new or revised accounting standards, and as a result, we may not implement new or revised accounting standards on the relevant dates on which adoption of such standards is required for other companies.

Subject to certain conditions set forth in the JOBS Act, as an emerging growth company, we intend to rely on certain of these exemptions, including without limitation, providing an auditor’s attestation report on our system of internal controls over financial reporting pursuant to Section 404 and implementing any requirement that may be adopted regarding mandatory audit firm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements (auditor discussion and analysis). These exemptions will apply for a period of five years following the completion of our IPO although if the market value of our common stock that is held by nonaffiliates exceeds $700 million as of any June 30 before that time, we would cease to be an emerging growth company as of the following December 31.

Critical Accounting Policies and Significant Judgments and Estimates

There have been no material changes in our critical accounting policies during the nine months ended September 30, 2017, as compared to those disclosed in “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Critical Accounting Policies and Significant Judgments and Estimates” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2016, filed with the SEC on March 14, 2017.

Results of Operations

Revenue 

We have not generated any revenue from product sales. For the periods presented, our revenues were derived from (i) the recognition of the upfront payments related to the Avacopan Agreement, Avacopan Amendment and CCX140 Agreement; (ii) collaboration revenue under the CCX140 Agreement and (iii) grant revenue from the FDA Orphan Products Development grant to support the clinical development of avacopan for the treatment of patients with AAV. Total revenue for the periods as compared to the same periods in the prior year were as follows (in thousands):

The increases in revenue from 2016 to 2017 for the three and nine month periods were due to; (i) amortization of the upfront license fee commitments from Vifor pursuant to the Avacopan Agreement, Avacopan Amendment and CCX140 Agreement, as well as (ii) collaboration revenue for development services under the CCX140 Agreement in the 2017 periods. These increases were partially offset by a decrease in grant revenue from the FDA to support the clinical development of avacopan for the treatment of patients with AAV.

Research and development expenses

Research and development expenses represent costs incurred to conduct basic research, the discovery and development of novel small molecule therapeutics, development of our suite of proprietary drug discovery technologies, preclinical studies and clinical trials of our drug candidates. We recognize all research and development expenses as they are incurred. These expenses consist primarily of salaries and related benefits, including stock-based compensation, third-party contract costs relating to research, formulation, manufacturing, preclinical study and clinical trial activities, laboratory consumables, and allocated facility costs. Total research and development expenses for the three and nine months ended September 30, 2017, as compared to the same period in the prior year, were as follows (in thousands):

The increase in research and development expenses from 2016 to 2017 for the three month period was primarily attributable to higher in Phase III clinical development expenses due to the initiation and patient enrollment of the avacopan ADVOCATE trial in patients with AAV and higher Phase II clinical development expense due to start-up expenses related to the clinical trial of avacopan for the treatment of C3G. These increases were partially offset by lower Phase II expenses due to the completion of the avacopan

CLEAR and CLASSIC clinical trials for the treatment of AAV in 2016. Decreased Phase I development expense was due to the completion of enrollment in the clinical trial for CCX872 in patients with advanced pancreatic cancer in 2016.

Research and development expenses increased from 2016 to 2017 for the nine month period primarily due to the initiation and patient enrollment of the avacopan Phase III ADVOCATE trial in patients with AAV and start-up expenses related to the Phase II clinical trial of avacopan for the treatment of C3G. These increases were partially offset by lower Phase II clinical development expense primarily due to the completion of the avacopan CLEAR and CLASSIC clinical trials for the treatment of AAV in 2016 and lower Phase I development expense due to the completion of enrollment in the clinical trial for CCX872 in patients with advanced pancreatic cancer in 2016.

The following table summarizes our research and development expenses (in thousands):

We track development expenses that are directly attributable to our clinical development candidates by phase of clinical development. Such development expenses include third-party contract costs relating to formulation, manufacturing, preclinical studies and clinical trial activities. We allocate research and development salaries, benefits or indirect costs to our development candidates and we have included such costs in research and development expenses. All remaining research and development expenses are reflected in “Research and drug discovery” which represents early stage drug discovery programs. Such expenses include allocated employee salaries and related benefits, stock-based compensation, consulting and contracted services to supplement our in-house laboratory activities, laboratory consumables and allocated facility costs associated with these earlier stage programs.

At any given time, we typically have several active early stage research and drug discovery projects. Our internal resources, employees and infrastructure are not directly tied to any individual research or drug discovery project and are typically deployed across multiple projects. As such, we do not maintain information regarding these costs incurred for our early stage research and drug discovery programs on a project specific basis. We expect our research and development expenses to increase as we advance our development programs further and increase the number and size of our clinical trials. The process of conducting preclinical studies and clinical trials necessary to obtain regulatory approval is costly and time consuming. We or our partners may never succeed in achieving marketing approval for any of our drug candidates. The probability of success for each drug candidate may be affected by numerous factors, including preclinical data, clinical data, competition, manufacturing capability and commercial viability. Our strategy includes entering into additional partnerships with third parties for the development and commercialization of some of our independent drug candidates.

The successful development of our drug candidates is highly uncertain and may not result in approved products. Completion dates and completion costs can vary significantly for each drug candidate and are difficult to predict for each product. Given the uncertainty associated with clinical trial enrollments and the risks inherent in the development process, we are unable to determine the duration and completion costs of the current or future clinical trials of our drug candidates or if, or to what extent, we will generate revenues from the commercialization and sale of any of our drug candidates. We anticipate we will make determinations as to which programs to pursue and how much funding to direct to each program on an ongoing basis in response to the scientific and clinical success of each drug candidate, as well as ongoing assessment as to each drug candidate’s commercial potential. We will need to raise additional capital or may seek additional strategic alliances in the future in order to complete the development and commercialization of our drug candidates, including avacopan, CCX140, CCX872 and vercirnon.

General and administrative expenses

Total general and administrative expenses for the three and nine months ended September 30, 2017, as compared to the same periods in the prior year were as follows (in thousands):

General and administrative expenses consist primarily of salaries and related benefits, including stock-based compensation and travel expenses, in executive, finance, business and corporate development and other administrative functions. Other general and administrative expenses include allocated facility-related costs not otherwise included in research and development expenses, legal costs of pursuing patent protection of our intellectual property, and professional fees for auditing, tax, and legal services.

The increase from 2016 to 2017 for the three month period was primarily due to higher accounting related fees associated with preparing to meet the requirements pursuant to the Sarbanes-Oxley Act of 2002. The increase from 2016 to 2017 for the nine month period was primarily due to higher intellectual property related expenses and accounting related fees partially offset by lower travel expenses.

We expect that general and administrative expenses will increase in the future as we expand our operating activities and incur additional expenses associated with preparing to meet the requirements pursuant to the Sarbanes-Oxley Act of 2002, including in connection with the expiration of our status as an emerging growth company, expected to occur in 2017.

Other income, net

Other income, net primarily consists of interest income earned on our marketable securities. Total other income, net, for the three and nine month periods, as compared to the same periods in the prior year was as follows (in thousands):

The increases in total other income, net from 2016 to 2017 for the three and nine month periods were primarily due to higher cash and investment balances in 2017 due to the receipt of upfront payments totaling $125.0 million received from Vifor in connection with the Avacopan Agreement, Avacopan Amendment and CCX140 Agreement.

Liquidity and Capital Resources

As of September 30, 2017, we had approximately $124.8 million in cash, cash equivalents and investments. Such amounts exclude $30.0 million in remaining upfront commitments in connection with the December 2016 CCX140 Agreement and February 2017 Avacopan Amendment, which are due on the first anniversary of these agreements. The following table shows a summary of our cash flows for the nine months ended September 30, 2017 and 2016 (in thousands):

Table of Contents

Operating activities. Net cash used in operating activities was $0.9 million for the nine months ended September 30, 2017, compared to $47.9 million provided by operating activities for the same period in 2016. This change was primarily due to changes in working capital items. For the nine months ended September 30, 2017, changes in working capital included the receipt of $30.0 million of accounts receivable from the first installment of the upfront commitment under the CCX140 Agreement. For the same period in 2016, changes in working capital included the receipt of $78.0 million, most of which was included as deferred revenue, in connection with the Avacopan Agreement.

Investing activities. Net cash provided by or used in investing activities for periods presented primarily relate to the purchases of investments and maturities of investments used to fund the day-to-day needs of our business.

Financing activities. Net cash provided by financing activities was $2.4 million for the nine months ended September 30, 2017, compared to $7.6 million for the same period in 2016. Net cash provided by financing activities for both periods presented included proceeds from the exercise of stock options and from employee purchases of stock under our 2012 Employee Stock Purchase Plan. For the nine months ended September 30, 2016, net cash provided also included the receipt of $7.0 million in net proceeds from the issuance of 3,333,333 shares of our common stock in connection with the Avacopan Agreement. For the nine months ended September 30, 2017, cash used for financing activities included $0.3 million (the value of withheld shares), for tendered ChemoCentryx, Inc. common stock to satisfy employee tax withholding requirements upon vesting of restricted stock units.

As of September 30, 2017, we had approximately $124.8 million in cash, cash equivalents and investments, excluding the $30.0 million in remaining upfront commitments in connection with the December 2016 CCX140 Agreement and the February 2017 Avacopan Amendment, which are due on the first anniversary of these agreements. We believe that our available cash, cash equivalents and investments will be sufficient to fund our anticipated level of operations for at least 12 months following our financial statement issuance date, November 7, 2017. However, our forecast of the period of time through which our financial resources will be adequate to support our operations is a forward-looking statement that involves risks and uncertainties, and actual results could vary materially.

Our future capital requirements are difficult to forecast and will depend on many factors, including:

Contractual Obligations and Commitments

There have been no material changes outside the ordinary course of our business to the contractual obligations we reported in our Annual Report on Form 10-K for the fiscal year ended December 31, 2016, filed with the SEC on March 14, 2017.
