"Exelixis delivered outstanding financial performance in the first quarter of 2025, driven by accelerating growth in CABOMETYX demand, new patient starts and revenues," said Michael M. Morrissey, Ph.D., President and Chief Executive Officer, Exelixis. "Based on the strong first quarter dynamics of CABOMETYX, we’re increasing our 2025 full year financial guidance for net product revenues and total revenues by $100 million. The Exelixis commercial team rapidly mobilized for the launch of CABOMETYX in advanced neuroendocrine tumors (NET) within hours of receiving U.S. regulatory approval in late March. We are very pleased with the initial reception and plan to provide further updates to our 2025 financial guidance as we build momentum on the NET launch and gain further clarity on additional revenue opportunities for 2025."

Dr. Morrissey continued: "As we work toward our goal of becoming a multi-franchise oncology company, we look forward to important potential milestones for zanzalintinib in the second half of 2025, based on anticipated event rates. These include pivotal trial readouts from STELLAR-303 in colorectal cancer and STELLAR-304 in non-clear cell renal cell carcinoma, as well as data to drive a decision to move into the phase 3 portion of the STELLAR-305 trial in head and neck cancer. We also look forward to the initiation of the STELLAR-311 pivotal study in neuroendocrine tumors in the first half of the year, and Merck’s anticipated initiation of two pivotal studies evaluating zanzalintinib and belzutifan in renal cell carcinoma. Furthermore, we continue to provide insights on our earlier-stage pipeline, with preclinical data presented on multiple programs at the AACR (Free AACR Whitepaper) Annual Meeting in April. I’m proud of the entire Exelixis team for our progress so far in 2025 and look forward to sharing additional updates throughout the year."

First Quarter 2025 Financial Results

Total revenues for the quarter ended March 31, 2025 were $555.4 million, as compared to $425.2 million for the comparable period in 2024.

Total revenues for the quarter ended March 31, 2025 included net product revenues of $513.3 million, as compared to $378.5 million for the comparable period in 2024. 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 $42.2 million for the quarter ended March 31, 2025, as compared to $46.7 million for the comparable period in 2024. The decrease in collaboration revenues was primarily related to lower royalty revenues for the sales of cabozantinib outside of the U.S. generated by Exelixis’ collaboration partners, Ipsen Pharma SAS (Ipsen) and Takeda Pharmaceutical Company Limited, and lower development cost reimbursements earned.

Research and development expenses for the quarter ended March 31, 2025 were $212.2 million, as compared to $227.7 million for the comparable period in 2024. The decrease in research and development expenses was primarily related to decreases in license and other collaboration costs and clinical trial costs, partially offset by increases in stock-based compensation and personnel expenses.

Selling, general and administrative expenses for the quarter ended March 31, 2025 were $137.2 million, as compared to $114.0 million for the comparable period in 2024. The increase in selling, general and administrative expenses was primarily related to increases in personnel expenses, corporate giving, and marketing expenses.

Provision for income taxes for the quarter ended March 31, 2025 was $46.1 million, as compared to $12.0 million for the comparable period in 2024.

GAAP net income for the quarter ended March 31, 2025 was $159.6 million, or $0.57 per share, basic and $0.55 per share, diluted, as compared to GAAP net income of $37.3 million, or $0.12 per share, basic and diluted, for the comparable period in 2024. GAAP net income per share for the quarter ended March 31, 2025 was favorably impacted by lower weighted-average common shares outstanding for the quarter ended March 31, 2025, as compared to the comparable period in 2024, as a result of the stock repurchase programs.

Non-GAAP net income for the quarter ended March 31, 2025 was $179.6 million, or $0.64 per share, basic and $0.62 per share, diluted, as compared to non-GAAP net income of $52.0 million, or $0.17 per share, basic and diluted, for the comparable period in 2024.

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, 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, 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 $513.3 million during the first quarter of 2025, with net product revenues of $510.9 million from CABOMETYX (cabozantinib) and $2.4 million from COMETRIQ (cabozantinib). Based upon cabozantinib-related net product revenues generated by Exelixis’ collaboration partners during the quarter ended March 31, 2025, Exelixis earned $36.7 million in royalty revenues.

Received U.S. Food and Drug Administration (FDA) Approval of CABOMETYX for Patients with Previously Treated Advanced NET. In March, Exelixis announced that the U.S. FDA approved CABOMETYX for the treatment of 1) adult and pediatric patients 12 years of age and older with previously treated, unresectable, locally advanced or metastatic, well-differentiated pancreatic NET (pNET); and 2) adult and pediatric patients 12 years of age and older with previously treated, unresectable, locally advanced or metastatic, well-differentiated extra-pancreatic NET (epNET). These latest FDA approvals — adding to five previous approvals for CABOMETYX — are based on results from CABINET, a phase 3 pivotal trial evaluating CABOMETYX compared with placebo in two cohorts of patients with previously treated NET: advanced pNET and advanced epNET. CABOMETYX is now the first and only systemic treatment that is FDA approved for previously treated NET regardless of primary tumor site, grade, somatostatin receptor expression and functional status. NET are heterogeneous tumors that arise from the neuroendocrine cells of the digestive tract and other organs, such as the lung and pancreas.

Announced Final Five-Year Follow-up Results from CheckMate -9ER Trial Evaluating CABOMETYX in Combination with Nivolumab (Opdivo) in Patients with Advanced Kidney Cancer at the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) 2025 Genitourinary Cancers Symposium (ASCO GU 2025). In February, final results from the phase 3 CheckMate -9ER pivotal trial evaluating CABOMETYX in combination with nivolumab versus sunitinib for patients with previously untreated advanced renal cell carcinoma (RCC) were presented at ASCO (Free ASCO Whitepaper) GU 2025. After more than five years of follow-up, the findings demonstrated that efficacy benefits with CABOMETYX in combination with nivolumab were sustained long term. Safety and tolerability with long-term follow-up were manageable and consistent with previous analyses. No new safety signals were reported.

Detailed Results from Subgroup Analysis of Phase 3 CABINET Pivotal Study Evaluating Cabozantinib in Advanced Gastrointestinal (GI) NET Presented at the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Gastrointestinal Cancers Symposium (ASCO GI 2025). In January, results from a subgroup analysis of the CABINET study of patients with epNET arising in the GI tract were featured in a poster session at ASCO (Free ASCO Whitepaper) GI 2025. The analysis showed cabozantinib was associated with an improvement in progression-free survival (PFS) compared with placebo in patients with advanced GI NET, which was a subgroup of the epNET cohort. Earlier in January, the National Comprehensive Cancer Network Clinical Practice Guidelines in Oncology for Neuroendocrine and Adrenal Tumors were updated to include cabozantinib as category 1 preferred regimen for the majority of well-differentiated advanced NET following specific treatments, and as a category 2A preferred regimen for other forms of advanced NET, depending on tumor grade and different requirements for prior therapy.

Encouraging Results from Phase 1b/2 STELLAR-001 Trial Evaluating Zanzalintinib Alone or in Combination with Atezolizumab (Tecentriq) in Metastatic Colorectal Cancer (CRC) Presented at ASCO (Free ASCO Whitepaper) GI 2025. In January, results from a randomized expansion cohort of the phase 1b/2 STELLAR-001 trial evaluating zanzalintinib versus the combination of zanzalintinib and atezolizumab in patients with previously treated metastatic CRC were presented during a poster session at ASCO (Free ASCO Whitepaper) GI 2025. Results from the study demonstrated that all efficacy parameters, including objective response rate, PFS and overall survival favored the combination of zanzalintinib plus atezolizumab over zanzalintinib monotherapy in the overall population, as well as in a subgroup of patients without liver metastases. These data provide insights into the contribution of components and support zanzalintinib’s ongoing pivotal development in metastatic CRC.

Presentation of Preclinical Data from Four Pipeline Programs in Advanced Cancers at the American Association for Cancer Research (AACR) (Free AACR Whitepaper) Annual Meeting (AACR 2025). In April, Exelixis presented preclinical data from four pipeline molecules at AACR (Free AACR Whitepaper) 2025. Presentations included data for XL309 and XL495, small molecules that have demonstrated synthetic lethality in the context of certain genetic anomalies found in varying frequencies across a broad array of tumor types. The XL309 findings demonstrated activity of XL309 as monotherapy or in combination with PARP or topoisomerase inhibitors. Data analysis from the XL495 program demonstrated the potential for anti-tumor activity both as a monotherapy and in combination with DNA-damaging agents. However, based on early clinical data generated for XL495, Exelixis has discontinued further development of this program. Preclinical data were also presented for the PD-L1 + NKG2A-targeting bispecific antibody XB628 and for the tissue factor-targeting antibody-drug conjugate XB371. Data analysis from the XB628 program demonstrated the molecule’s tumor cell killing activity both in vitro and in vivo, supporting advancement of this molecule into clinical development. Earlier in March, the U.S. FDA cleared Exelixis’ Investigational New Drug (IND) application for XB628, and the company initiated the phase 1 study in April. Findings from XB371 non-clinical experiments demonstrated potent anti-tumor activity in vivo across a range of human tumor xenograft models including colorectal, lung, and pancreatic cancers, supporting the molecule’s advancement into phase 1 clinical development. Exelixis is on track to submit an IND application for XB371 to the FDA in 2025.

Cabozantinib and Zanzalintinib Data Presentations at the 2025 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting (ASCO 2025). Cabozantinib and zanzalintinib will be the subject of 17 presentations at ASCO (Free ASCO Whitepaper) 2025, which is being held from May 30 through June 3 in Chicago. Notably, presentations will include health-related quality of life findings from the phase 3 CABINET pivotal trial for cabozantinib, as well as results from two dose-escalation cohorts in advanced solid tumors and a clear cell RCC expansion cohort of the phase 1b/2 STELLAR-002 trial evaluating zanzalintinib in combination with immune checkpoint inhibitors in advanced solid tumors.

Corporate Highlights

Stock Repurchase Program. In August 2024, Exelixis’ Board of Directors authorized a stock repurchase program to acquire up to $500 million of the company’s common stock before December 31, 2025. In February 2025, the Board of Directors authorized the repurchase of up to an additional $500 million of the company’s common stock before December 31, 2025. Under these programs, as of March 31, 2025, Exelixis has repurchased $494.5 million of the company’s common stock, at an average price of $34.87 per share. Since the approval of the first stock repurchase program in March 2023, the weighted-average diluted common shares outstanding has decreased from 326.3 million shares to 288.2 million shares as of March 31, 2025. Stock repurchases under these programs 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 stock repurchases under the stock repurchase programs 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 our common stock and general market conditions.

Basis of Presentation

Exelixis has adopted a 52- or 53-week fiscal year that generally ends on the Friday closest to December 31.

General and Administrative (G&A) Expenses: G&A expenses were $9.7 million for the quarter ended March 31, 2025, compared to $10.3 million for the quarter ended March 31, 2024. The decrease was primarily driven by decreases in legal fees and insurance costs.

Net Loss: Net loss was $31.0 million, or $(0.11) per basic and diluted share, for the quarter ended March 31, 2025, compared to $35.0 million, or $(0.23) per basic and diluted share, for the quarter ended March 31, 2024.

CytoDyn Announces Data Suggesting Novel Mechanism of Action of Leronlimab for the Treatment of Solid Tumors

On May 13, 2025 CytoDyn Inc. (OTCQB: CYDY) ("CytoDyn" or the "Company"), a biotechnology company developing leronlimab, a CCR5 antagonist with the potential for multiple therapeutic indications, reported new data suggesting a novel mechanism of action of leronlimab for the treatment of solid tumors (Press release, CytoDyn, MAY 13, 2025, View Source [SID1234652962]).

CytoDyn analyzed data from its prior clinical trials of patients with metastatic Triple-Negative Breast Cancer ("mTNBC") and found that leronlimab treatment correlated with increased expression of an immune cell protein or "checkpoint inhibitor" known as programmed death-ligand 1 ("PD-L1") on patient’s circulating tumor cells ("CTCs"). CytoDyn’s results indicate that 15/17 (88%) of patients who received a weekly dose of 525 mg or higher experienced a significant increase in PD-L1 expression on their CTCs over a 30-to-90-day period after starting leronlimab. Increasing expression of PD-L1 can be likened to turning "cold" tumors "hot", elevating PD-L1 levels to the level necessary for patients to potentially derive benefit from further treatment with a class of drugs known as immune checkpoint inhibitors ("ICIs").

As previously announced, CytoDyn identified a group of patients with mTNBC who had failed a median of two prior lines of treatment in the metastatic setting but showed improved overall survival rates after receiving leronlimab. The Company confirmed that 5/5 patients (100%) who demonstrated a significant increase in PD-L1 expression after receiving leronlimab and received treatment with any ICI remain alive today. Four of these patients (80%) currently identify as having no evidence of disease, and the fifth patient is alive and identified by the clinical site as "stable."

If the results above are confirmed prospectively, the Company believes the mechanism could be effective across a wide range of solid tumor types, and in particular benefit cancer patients with low levels of PD-L1 who were previously unresponsive to or ineligible for checkpoint inhibitors.

"Leronlimab’s induction of PD-L1 on CTCs in patients with otherwise "cold" tumors opens a promising field of exploration for what could amount to significant improvements to patient care and outcomes in solid tumor oncology," said Richard Pestell, MD, PhD, AO, the Company’s Lead Consultant in Preclinical and Clinical Oncology. "We are hopeful that further short-term investigation will confirm our working theory and open new pathways for patients with a range of common and aggressive forms of cancer to access treatment options that were previously out of reach."

"We are thrilled to announce this apparent mechanism behind the improved survival in patients with refractory and metastatic TNBC," said Dr. Jacob Lalezari, CEO of CytoDyn. "Leronlimab’s ability to induce an inflamed or "hot" tumor environment, that could then be treated with ICIs, would be a game changer in solid tumor oncology. Prospectively confirming these findings in patients with TNBC is a top priority. We have also amended our current colorectal cancer trial to ensure the prospective collection of PD-L1 data in a second type of solid tumor."

Immune-mediated adverse reactions listed herein may not include all possible severe and fatal immune-mediated adverse reactions. Immune-mediated adverse reactions, which can be severe or fatal, can occur in any organ system or tissue, and occur at any time after starting a PD-1/PD-L1–blocking antibody, including UNLOXCYT. While immune-mediated adverse reactions usually manifest during treatment, they can also manifest after discontinuation of PD-1/PD-L1–blocking antibodies. Immune-mediated adverse reactions affecting more than one body system can occur simultaneously.
Monitor closely for signs and symptoms of immune-mediated adverse reactions. Evaluate liver enzymes, creatinine, and thyroid function tests at baseline and periodically during treatment. In cases of suspected immune-mediated adverse reactions, initiate appropriate workup to exclude alternative etiologies, including infection. Institute medical management promptly, including specialty consultation as appropriate.
Withhold or permanently discontinue UNLOXCYT depending on the severity of the adverse reaction (see Dosage and Administration in Prescribing Information). In general, if UNLOXCYT requires interruption or discontinuation, administer systemic corticosteroids (1 to 2 mg/kg/day prednisone or equivalent) until improvement to Grade 1 or less. Upon improvement to Grade 1 or less, initiate corticosteroid taper and continue to taper over at least 1 month. Consider administration of other systemic immunosuppressants in patients whose immune-mediated adverse reaction is not controlled with corticosteroids.
Immune-Mediated Pneumonitis

UNLOXCYT can cause immune-mediated pneumonitis. In patients treated with other PD-1/PD-L1–blocking antibodies, the incidence of pneumonitis is higher in patients who have received prior thoracic radiation. Immune-mediated pneumonitis occurred in 1% (3/223, Grade 2) of patients receiving UNLOXCYT.
Immune-Mediated Colitis

UNLOXCYT can cause immune-mediated colitis, which may present with diarrhea, abdominal pain, and lower gastrointestinal bleeding. Cytomegalovirus infection/reactivation has occurred in patients with corticosteroid-refractory immune-mediated colitis treated with PD-1/PD-L1–blocking antibodies. In cases of corticosteroid-refractory colitis, consider repeating infectious workup to exclude alternative etiologies. Immune-mediated colitis occurred in 0.4% (1/223, Grade 1) of patients receiving UNLOXCYT.
Immune-Mediated Hepatitis

UNLOXCYT can cause immune-mediated hepatitis.
Immune-Mediated Endocrinopathies
Adrenal Insufficiency

UNLOXCYT can cause primary or secondary adrenal insufficiency. For Grade 2 or higher adrenal insufficiency, initiate symptomatic treatment per institutional guidelines, including hormone replacement as clinically indicated. Withhold or permanently discontinue UNLOXCYT depending on severity. Adrenal insufficiency occurred in 0.9% (2/223) of patients receiving UNLOXCYT, including Grade 2 in 0.4% (1/223) of patients.
Hypophysitis

UNLOXCYT can cause immune-mediated hypophysitis. Hypophysitis can present with acute symptoms associated with mass effect such as headache, photophobia, or visual field cuts. Hypophysitis can cause hypopituitarism. Initiate hormone replacement as clinically indicated. Withhold or permanently discontinue UNLOXCYT depending on severity.
Thyroid Disorders

UNLOXCYT can cause immune-mediated thyroid disorders. Thyroiditis can present with or without endocrinopathy. Hypothyroidism can follow hyperthyroidism. Initiate hormone replacement or medical management of hyperthyroidism as clinically indicated. Withhold or permanently discontinue UNLOXCYT depending on severity. Hypothyroidism occurred in 10% (22/223) of patients receiving UNLOXCYT, including Grade 2 in 5% (10/223) of patients. Hyperthyroidism occurred in 5% (12/223) of patients receiving UNLOXCYT, including Grade 2 in 0.4% (1/223) of patients.
Type 1 Diabetes Mellitus, Which Can Present with Diabetic Ketoacidosis

UNLOXCYT can cause type 1 diabetes mellitus, which can present with diabetic ketoacidosis. Monitor patients for hyperglycemia or other signs and symptoms of diabetes. Initiate treatment with insulin as clinically indicated. Withhold or permanently discontinue UNLOXCYT depending on severity.
Immune-Mediated Nephritis with Renal Dysfunction

UNLOXCYT can cause immune-mediated nephritis.
Immune-Mediated Dermatologic Adverse Reactions

UNLOXCYT can cause immune-mediated rash or dermatitis. Bullous and exfoliative dermatitis, including Stevens-Johnson syndrome, toxic epidermal necrolysis, and drug rash with eosinophilia and systemic symptoms, have occurred with PD-1/PD-L1–blocking antibodies. Topical emollients and/or topical corticosteroids may be adequate to treat mild to moderate non-bullous/exfoliative rashes. Withhold or permanently discontinue UNLOXCYT depending on severity. Immune-mediated dermatologic adverse reactions occurred in 7% (15/223) of patients receiving UNLOXCYT, including Grade 3 in 0.9% (2/223) of patients and Grade 2 in 4% (9/223) of patients.
Other Immune-Mediated Adverse Reactions

The following clinically significant immune-mediated adverse reactions occurred in <1% of the 223 patients who received UNLOXCYT or were reported with the use of other PD-1/PD-L1–blocking antibodies. Severe or fatal cases have been reported for some of these adverse reactions.
Cardiac/Vascular: Myocarditis, pericarditis, vasculitis.
Nervous System: Meningitis, encephalitis, myelitis and demyelination, myasthenic syndrome/myasthenia gravis (including exacerbation), Guillain-Barre syndrome, nerve paresis, autoimmune neuropathy.
Ocular: Uveitis, iritis, other ocular inflammatory toxicities. Some cases can be associated with retinal detachment. Various grades of visual impairment to include blindness can occur. If uveitis occurs in combination with other immune-mediated adverse reactions, consider a Vogt-Koyanagi-Harada–like syndrome, as this may require treatment with systemic steroids to reduce the risk of permanent vision loss.
Gastrointestinal: Pancreatitis, including increases in serum amylase and lipase levels, gastritis, duodenitis.
Musculoskeletal and Connective Tissue: Myositis/polymyositis, rhabdomyolysis and associated sequelae including renal failure, arthritis, polymyalgia rheumatica.
Endocrine: Hypoparathyroidism.
Other (Hematologic/Immune): Autoimmune hemolytic anemia, aplastic anemia, hemophagocytic lymphohistiocytosis, systemic inflammatory response syndrome, histiocytic necrotizing lymphadenitis (Kikuchi lymphadenitis), sarcoidosis, immune thrombocytopenia, solid organ transplant rejection, other transplant (including corneal graft) rejection.
Infusion-Related Reactions

UNLOXCYT can cause severe or life-threatening infusion-related reactions. Infusion-related infusion reactions were reported in 11% (24/223) of patients, including Grade 2 in 5.8% (13/223) of patients receiving UNLOXCYT.
Monitor patients for signs and symptoms of infusion-related reactions. Interrupt or slow the rate of infusion or permanently discontinue UNLOXCYT based on severity of reaction. Consider premedication with an antipyretic and/or an antihistamine for patients who have had previous systemic reactions to infusions of therapeutic proteins.
Complications of Allogeneic HSCT

Fatal and other serious complications can occur in patients who receive allogeneic hematopoietic stem cell transplantation ("HSCT") before or after being treated with a PD-1/PD-L1–blocking antibody. Transplant-related complications include hyperacute graft-versus-host disease ("GVHD"), acute GVHD, chronic GVHD, hepatic veno-occlusive disease after reduced intensity conditioning, and steroid-requiring febrile syndrome (without an identified infectious cause). These complications may occur despite intervening therapy between PD-1/PD-L1 blockade and allogeneic HSCT. Follow patients closely for evidence of transplant-related complications and intervene promptly. Consider the benefit versus risks of treatment with a PD-1/PD-L1–blocking antibody prior to or after an allogeneic HSCT.
Embryo-Fetal Toxicity

Based on its mechanism of action, UNLOXCYT can cause fetal harm when administered to a pregnant woman. Animal studies have demonstrated that inhibition of the PD-1/PD-L1 pathway can lead to increased risk of immune-mediated rejection of the developing fetus, resulting in fetal death. Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment with UNLOXCYT and for 4 months after the last dose.
Common Adverse Reactions
The most common adverse reactions (≥10%) were fatigue, musculoskeletal pain, rash, diarrhea, hypothyroidism, constipation, nausea, headache, pruritus, edema, localized infection, and urinary tract infection.
