Exelixis, Inc. (Nasdaq: EXEL) today reported financial results for the first quarter of 2024, provided an update on progress toward achieving key corporate objectives, and detailed its recent and anticipated commercial, clinical and pipeline development milestones.

“In the first quarter of 2024, Exelixis made important progress to advance a diverse, multi-product portfolio of small molecules and biotherapeutics with the potential to improve standards of care for patients with cancer,” said Michael M. Morrissey, Ph.D., President and Chief Executive Officer, Exelixis. “The team continued to execute across our three ongoing pivotal trials for zanzalintinib, as well as the phase 1 studies of our tissue-factor targeting ADC, XB002, and our small molecule USP1 inhibitor, XL309. We expect to provide updates from these programs as clinical data mature. In addition, we are on track for up to three Investigational New Drug filings this year, pending continued supportive preclinical data.”

Dr. Morrissey continued: “We also continued to pursue our label expansion plans for cabozantinib to drive future potential revenue growth of our flagship franchise and will provide additional updates on our regulatory strategies for both neuroendocrine tumors and metastatic castration-resistant prostate cancer, when appropriate. We believe the recent restructuring of our business, announced in January, further enhances our integrated research, development and commercial capabilities to deliver an innovative pipeline of cancer therapies for patients, while continuing to return capital back to our shareholders through our 2024 share repurchase program. As we drive the commercial and pipeline components of our business forward, we remain steadfast in our defense of cabozantinib’s intellectual property and anticipate a ruling on the second bench trial for our ongoing litigation with MSN Pharmaceuticals in the spring timeframe of this year.”

First Quarter 2024 Financial Results

Total revenues for the quarter ended March 31, 2024 were $425.2 million, as compared to $408.8 million for the comparable period in 2023.

Total revenues for the quarter ended March 31, 2024 included net product revenues of $378.5 million, as compared to $363.4 million for the comparable period in 2023. The increase in net product revenues was primarily due to an increase in sales volume, partially offset by a decrease in average net selling price.

Collaboration revenues, composed of license revenues and collaboration services revenues, were $46.7 million for the quarter ended March 31, 2024, as compared to $45.4 million for the comparable period in 2023. The increase in collaboration revenues was primarily due to higher royalty revenues for the sales of cabozantinib outside of the U.S. generated by Exelixis’ collaboration partners, Ipsen Pharma SAS and Takeda Pharmaceutical Company Limited, partially offset by a decrease in development cost reimbursements earned.

Research and development expenses for the quarter ended March 31, 2024 were $227.7 million, as compared to $234.2 million for the comparable period in 2023. The decrease in research and development expenses was primarily related to a decrease in license and other collaboration costs, partially offset by an increase in clinical trial costs.

Selling, general and administrative expenses for the quarter ended March 31, 2024 were $114.0 million, as compared to $131.4 million for the comparable period in 2023. The decrease in selling, general and administrative expenses were primarily related to decreases in corporate giving and legal and advisory fees.

Restructuring expenses for the quarter ended March 31, 2024 were $32.8 million. The restructuring expenses primarily consist of severance and employee-related costs, asset impairment and contract termination costs.

Provision for income taxes for the quarter ended March 31, 2024 was $12.0 million, as compared to $8.3 million for the comparable period in 2023.

GAAP net income for the quarter ended March 31, 2024 was $37.3 million, or $0.12 per share, basic and diluted, as compared to GAAP net income of $40.0 million, or $0.12 per share, basic and diluted, for the comparable period in 2023. GAAP net income per share for the quarter ended March 31, 2024 was favorably impacted by lower weighted-average common shares outstanding for the quarter ended March 31, 2024, as compared to the comparable period in 2023, as a result of the stock repurchase programs.

Non-GAAP net income for the quarter ended March 31, 2024 was $52.0 million, or $0.17 per share, basic and diluted, as compared to non-GAAP net income of $52.8 million, or $0.16 per share, basic and diluted, for the comparable period in 2023.

Non-GAAP Financial Measures

To supplement Exelixis’ financial results presented in accordance with U.S. Generally Accepted Accounting Principles (GAAP), Exelixis presents non-GAAP net income (and the related per share measures), which excludes from GAAP net income (and the related per share measures) stock-based compensation expense, adjusted for the related income tax effect for all periods presented.

Exelixis believes that the presentation of these non-GAAP financial measures provides useful supplementary information to, and facilitates additional analysis by, investors. In particular, Exelixis believes that these non-GAAP financial measures, when considered together with its financial information prepared in accordance with GAAP, can enhance investors’ and analysts’ ability to meaningfully compare Exelixis’ results from period to period, and to identify operating trends in Exelixis’ business. Exelixis has excluded stock-based compensation expense, adjusted for the related income tax effect, because it is a non-cash item that may vary significantly from period to period as a result of changes not directly or immediately related to the operational performance for the periods presented. Exelixis also regularly uses these non-GAAP financial measures internally to understand, manage and evaluate its business and to make operating decisions.

These non-GAAP financial measures are in addition to, not a substitute for, or superior to, measures of financial performance prepared in accordance with GAAP. Exelixis encourages investors to carefully consider its results under GAAP, as well as its supplemental non-GAAP financial information and the reconciliation between these presentations, to more fully understand Exelixis’ business. Reconciliations between GAAP and non-GAAP results are presented in the tables of this release.

Cabozantinib and Pipeline Highlights

Cabozantinib Franchise Net Product Revenues and Royalties. Net product revenues generated by the cabozantinib franchise in the U.S. were $378.5 million during the first quarter of 2024, with net product revenues of $376.4 million from CABOMETYX^® (cabozantinib) and $2.1 million from COMETRIQ^® (cabozantinib). Based upon cabozantinib-related net product revenues generated by Exelixis’ collaboration partners during the quarter ended March 31, 2024, Exelixis earned $39.6 million in royalty revenues.

Detailed Results from Phase 3 CONTACT-02 Pivotal Trial Evaluating Cabozantinib in Combination with Atezolizumab in Metastatic Castration-Resistant Prostate Cancer (mCRPC) Presented at the American Society of Clinical Oncology 2024 Genitourinary Cancers Symposium (ASCO GU). In January, positive results from the primary progression-free survival (PFS) analysis in the global phase 3 CONTACT-02 pivotal trial were presented during an oral abstract session at ASCO GU. The results demonstrated a statistically significant improvement in PFS, as assessed by a blinded independent radiology committee (BIRC), for cabozantinib in combination with atezolizumab in the first 400 randomized patients in the intent-to-treat (PFS ITT) population and per protocol. A PFS benefit was observed across all subgroups of high-risk populations who have a poor prognosis and a high unmet need for additional treatment options, notably in patients with liver metastases or those who had received prior docetaxel chemotherapy. A statistically significant improvement in PFS was also observed by BIRC both in the ITT population (n=507) and according to Prostate Cancer Clinical Trials Working Group 3 (PCWG3) criteria. An interim analysis for overall survival (OS), conducted at the time of the primary PFS analysis, demonstrated a trend favoring the combination of cabozantinib and atezolizumab. The study continues toward the next analysis of OS, which is anticipated in 2024. CONTACT-02 is evaluating cabozantinib in combination with atezolizumab compared with a second novel hormonal therapy (NHT) in patients with mCRPC and measurable soft-tissue disease who have progressed on one prior NHT. The safety profile of the combination regimen was consistent with the known profiles of each single agent, and no new safety findings were identified.

Four-Year Follow-up Results from Phase 3 CheckMate -9ER Trial Evaluating CABOMETYX in Combination with Nivolumab (OPDIVO^®) in Previously Untreated Renal Cell Carcinoma (RCC) Presented at ASCO GU. In January, four-year follow-up results from the CheckMate -9ER trial were featured in an oral presentation at ASCO GU. Results continued to show superior PFS and objective response rates in patients treated with the combination of CABOMETYX and nivolumab over sunitinib, the comparator studied in the trial, regardless of risk classification. Superior OS was also observed in patients treated with the combination. The presentation included data showing health-related quality-of-life benefits with the combination as compared to sunitinib. No new safety concerns were identified in the follow-up analysis.

Cabozantinib and Zanzalintinib Data Presentations at the 2024 American Society of Clinical Oncology (ASCO) Annual Meeting. Cabozantinib and zanzalintinib will be the subject of 10 presentations at this year’s ASCO Annual Meeting, which is being held from May 31 through June 4 in Chicago. Notably, presentations will include a biomarker analysis from the clear cell RCC cohort of the phase 1b/2 STELLAR-001 study of zanzalintinib in advanced solid tumors.

Corporate Highlights

Announcement of Key Priorities and Anticipated Milestones for 2024. In January, Exelixis announced its key priorities and anticipated milestones for 2024, including: implementation of a corporate restructuring to prioritize the advancement of the company’s deep pipeline of clinical and near-clinical programs; potential U.S. regulatory filings for cabozantinib in advanced NET and mCRPC indications; the anticipated outcome of the cabozantinib Abbreviated New Drug Application litigation with MSN Pharmaceuticals in the Spring timeframe of 2024; expansion of zanzalintinib’s pivotal development program with priorities defined by emerging phase 1b/2 data and potential clinical co-funding opportunities; advancing JEWEL-101, the phase 1 study of XB002, a next-generation tissue factor-targeting antibody-drug conjugate (ADC), alone and in combination with immunotherapy in a variety of solid tumor settings with the goal of prioritizing sensitive tumor types for full development; accelerating the phase 1 development of XL309, a potentially best-in-class small molecule inhibitor of USP1, as a potential therapy for tumors that have become refractory to PARP inhibitor (PARPi) therapy, including forms of ovarian, breast and prostate cancers, and pursuing potential PARPi combinations; potentially filing three Investigational New Drug applications for XB010 (5T4-MMAE ADC), XB628 (PD-L1 + NKG2A bispecific antibody), and XL495 (small molecule PKMYT1 inhibitor) if preclinical data continue to be supportive; and advancing two new programs to development candidate status, including a small molecule PLK4 inhibitor and an additional ADC. Exelixis presented the details of its key priorities and anticipated milestones at the 42^nd Annual J.P. Morgan Healthcare Conference.

Share Repurchase Program. As of March 31, 2024, Exelixis has repurchased $190.7 million of the company’s common stock, at an average price of $22.08 per share. In January, Exelixis announced that the company’s Board of Directors authorized the repurchase of up to an additional $450 million of the company’s common stock before the end of 2024. Upon fulfillment of the 2024 share repurchase program, the company expects to have returned $1 billion to shareholders over two years along with the 2023 program successfully completed in December 2023. Share repurchases under the 2024 program may be made from time to time through a variety of methods, which may include open market purchases, in block trades, accelerated share repurchase transactions, exchange transactions, or any combination of such methods. The timing and amount of any share repurchases under the share repurchase program will be based on a variety of factors, including ongoing assessments of the capital needs of the business, alternative investment opportunities, the market price of Exelixis’ common stock and general market conditions.

Appointments of Two New Board Members with Extensive Drug Development and Corporate Governance Expertise. In January, Exelixis announced the appointments of Mary C. Beckerle, Ph.D., and S. Gail Eckhardt, M.D., to the Exelixis Board of Directors, effective January 5, 2024.
