Exelixis, Inc. (Nasdaq: EXEL) today reported financial results for the first quarter of 2023 and provided an update on progress toward achieving key corporate objectives, as well as commercial, clinical and pipeline development milestones.

“The Exelixis team continued to execute on our key priorities and made significant progress in advancing our commercial business and our growing pipeline,” said Michael M. Morrissey, Ph.D., President and Chief Executive Officer, Exelixis. “CABOMETYX^® maintained its status as the leading tyrosine kinase inhibitor in renal cell carcinoma in the first quarter, driven by its use in combination with nivolumab in the first-line setting. We’ve made important progress across our pipeline programs, including advancing the STELLAR-303 and STELLAR-304 phase 3 trials for zanzalintinib, as well as single-agent and combination dose-escalation cohorts of the phase 1 trial of XB002. We are on track to initiate additional pivotal studies for zanzalintinib in 2023 and are focused on accelerating XB002 into full development by year-end.”

Dr. Morrissey continued: “Our collaborations with Cybrexa and Sairopa also made steady progress. Sairopa received clearance of its Investigational New Drug application for ADU-1805 from the U.S. Food and Drug Administration in February and subsequently initiated the phase 1 study in March. Cybrexa is planning to present updated phase 1 data for CBX-12 at the ASCO Annual Meeting in June. In March, we announced a share repurchase program for up to $550 million of our common stock before the end of 2023, which reflects continued confidence in our long-term prospects and the strength of our balance sheet and reinforces our commitment to deliver value to shareholders. I’d like to thank the entire Exelixis team for their collective hard work and dedication to improving the standard-of-care for patients while driving sustainable, long-term value for shareholders as we advance our mission to help cancer patients recover stronger and live longer.”

First Quarter 2023 Financial Results

Total revenues for the quarter ended March 31, 2023 were $408.8 million, as compared to $356.0 million for the comparable period in 2022.

Total revenues for the quarter ended March 31, 2023 included net product revenues of $363.4 million, as compared to $310.3 million for the comparable period in 2022. The increase in net product revenues was primarily due to an increase in sales volume and an increase in average net selling price.

Collaboration revenues, composed of license revenues and collaboration services revenues, were $45.4 million for the quarter ended March 31, 2023, as compared to $45.7 million for the comparable period in 2022. The decrease in collaboration revenues was primarily related to a decrease in development cost reimbursements earned, which was offset by 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.

Research and development expenses for the quarter ended March 31, 2023 were $234.2 million, as compared to $156.7 million for the comparable period in 2022. The increase in research and development expenses was primarily related to increases in license and other collaboration costs, personnel expenses and manufacturing costs to support our development candidates, which were partially offset by lower stock-based compensation expense.

Selling, general and administrative expenses for the quarter ended March 31, 2023 were $131.4 million, as compared to $102.9 million for the comparable period in 2022. The increase in selling, general and administrative expenses was primarily related to an increase in personnel expenses.

Provision for income taxes for the quarter ended March 31, 2023 was $8.3 million, as compared to $16.7 million for the comparable period in 2022, primarily due to a decrease in pre-tax income.

GAAP net income for the quarter ended March 31, 2023 was $40.0 million, or $0.12 per share, basic and diluted, as compared to GAAP net income of $68.6 million, or $0.21 per share, basic and diluted, for the comparable period in 2022.

Non-GAAP net income for the quarter ended March 31, 2023 was $52.8 million, or $0.16 per share, basic and diluted, as compared to non-GAAP net income of $83.9 million, or $0.26 per share, basic and diluted, for the comparable period in 2022.

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.

Exelixis is maintaining the previously provided financial guidance for fiscal year 2023:

Cabozantinib Highlights

Cabozantinib Franchise Net Product Revenues and Royalties. Net product revenues generated by the cabozantinib franchise in the U.S. were $363.4 million during the first quarter of 2023, with net product revenues of $361.8 million from CABOMETYX^® (cabozantinib) and $1.6 million from COMETRIQ^® (cabozantinib). Based upon cabozantinib-related net product revenues generated by Exelixis’ collaboration partners during the quarter ended March 31, 2023, Exelixis earned $32.7 million in royalty revenues.

Cabozantinib Data at the 2023 American Society of Clinical Oncology (ASCO) Genitourinary Cancers Symposium (ASCO GU 2023). In February, cabozantinib was the subject of multiple data presentations at ASCO GU 2023, held from February 16-18, 2023. Notable presentations included: 44-month median follow-up data and biomarker analyses from CheckMate -9ER, the phase 3 pivotal trial of cabozantinib in combination with nivolumab; outcomes by International Metastatic Renal Cell Carcinoma Database Consortium (IMDC) risk score in COSMIC-313, the phase 3 pivotal trial of cabozantinib, nivolumab and ipilimumab; and extended follow-up results from a non-clear cell renal cell carcinoma (RCC) cohort of COSMIC-021, the ongoing phase 1b trial of cabozantinib in combination with atezolizumab.

Cabozantinib Data Presentations at the 2023 ASCO Annual Meeting. In June 2023, cabozantinib will be the subject of 22 presentations at this year’s ASCO Annual Meeting, which is being held from June 2-6 in Chicago. Notable presentations will include results from the CONTACT-03 phase 3 trial evaluating the combination of cabozantinib and atezolizumab vs. cabozantinib alone in metastatic RCC patients who have progressed following treatment with an immune checkpoint inhibitor therapy, and three-year quality-of-life follow-up data from CheckMate -9ER.

Corporate Updates

Announcement of Key Priorities and Anticipated Milestones for 2023. In January 2023, Exelixis announced its key priorities and anticipated milestones for 2023, including: pivotal data readouts from the ongoing phase 3 studies evaluating the combination of cabozantinib with atezolizumab in patients with forms of metastatic castration-resistant prostate cancer (CONTACT-02) and RCC (CONTACT-03), the latter of which has subsequently occurred, and the next overall survival (OS) analysis from the phase 3 COSMIC-313 pivotal study for cabozantinib; expansion of the pivotal development program for zanzalintinib with multiple new phase 3 pivotal trial initiations; acceleration of the XB002 clinical program into full development by year-end; advancement of the XL102 QUARTZ-101 phase 1 study into the tumor-specific cohort-expansion stage and in planned combination cohorts; in collaboration with partner Cybrexa, progression of the phase 1 clinical study for CBX-12, including dose-expansion cohorts; expected filing of an Investigational New Drug application (IND) for ADU-1805 with the U.S. Food and Drug Administration (FDA) in the first quarter of 2023 by partner Sairopa B.V. (Sairopa), which has subsequently occurred; advancement of development candidates (DCs) XB010, XB014 and XB628 toward IND filings; and progress up to five new DCs into preclinical development across biotherapeutics and small molecules. Exelixis presented the details of its key priorities and anticipated milestones at the 41^st Annual J.P. Morgan Healthcare Conference.

Cabozantinib Abbreviated New Drug Application (ANDA) Litigation Against MSN Pharmaceuticals, Inc. (MSN). In January 2023, the U.S. District Court for the District of Delaware (the Delaware District Court) ruled in Exelixis’ favor in the ANDA lawsuit against MSN (MSN I), rejecting MSN’s challenge to the cabozantinib compound patent (U.S. Patent No. 7,759,473). Additionally, the District Court ruled that MSN’s proposed ANDA product does not infringe Exelixis’ N-2 polymorph patent (U.S. Patent No. 8,877,776), expiring in October 2030. The decision in MSN I does not address the validity of the ‘776 patent, which was not contested by MSN, and the Delaware District Court entered judgment that any final FDA approval of MSN’s ANDA shall not be a date earlier than August 14, 2026, the expiration date of the ‘473 patent. In addition, this ruling in MSN I does not impact Exelixis’ separate and ongoing suit against MSN (MSN II) concerning four different Orange Book-listed patents related to cabozantinib, which expire between January 15, 2030, and February 10, 2032. A bench trial in MSN II is scheduled to begin in October 2023 in the U.S. District Court for the District of Delaware.

Announcement of $550 Million Share Repurchase Program. In March, Exelixis announced that the company’s Board of Directors authorized the repurchase of up to $550 million of the company’s common stock before the end of 2023. Share repurchases under the 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.

Pipeline Highlights

Exelixis and Sairopa Announce FDA Clearance of IND for ADU-1805 in Patients with Advanced Solid Tumors. In February, Exelixis and Sairopa announced FDA clearance of Sairopa’s IND to evaluate the safety and pharmacokinetics in a Phase 1 clinical trial of ADU-1805 in adults with advanced solid tumors, which has since been initiated. As a monoclonal antibody active against all human alleles of SIRPα, ADU-1805 has the potential to address a broader patient population than other SIRPα-directed therapies. By blocking SIRPα, a significant immune-suppressive component of the tumor microenvironment, ADU-1805 has the potential to improve the immune system’s ability to attack tumors. Under the terms of the clinical development and option agreement announced in November 2022, Exelixis has the option to obtain an exclusive, worldwide license to develop and commercialize ADU-1805 and other anti-SIRPα antibodies upon review of data from prespecified phase 1 clinical studies to be completed by Sairopa during the option period. This IND clearance triggered a $35.0 million milestone payment to Sairopa, paid in the first quarter of 2023.

Basis of Presentation

Exelixis has adopted a 52- or 53-week fiscal year that generally ends on the Friday closest to December 31^st. For convenience, references in this press release as of and for the fiscal period ended April 1, 2022 is indicated as being as of and for the period ended March 31, 2022.
