Cabozantinib (s)-Malate

The Institute for Clinical and Economic Review on Thursday released a new report arguing that US healthcare costs rose by more than $800 million from price increases on just five drugs’ net prices, hikes that weren’t backed by new clinical evidence. The five drugs with these “unsupported price increases,” ICER says, include Gilead’s HIV/AIDS drug Biktarvy, J&J’s multiple myeloma drug Darzalex, Novartis’ heart drug Entresto, which is one of the first drugs under government price negotiation in 2026, Exelixis’ cancer drug Cabometyx, and Pfizer’s Xeljanz, which can treat inflammatory and autoimmune conditions. To select the top 10, the group looked at 250 drugs, chosen because of their 2023 net sales revenue. It also flagged five drugs with new evidence backing their use that didn’t make the “unsupported” list, but emphasized that those “should not be interpreted to mean that the new evidence justifies the level of price increase; a full cost-effectiveness assessment was not conducted to determine the comparative value.” The topic, and ICER’s list, routinely generate pushback from drug companies that disagree with how the review is conducted. The National Pharmaceutical Council, a drug industry trade group, argued that the reports “do more harm than good: They have serious methodological limitations, contradict ICER’s core value assessment framework, and ignore a tremendous amount of evidence submitted by manufacturers.” Kimberly Westrich, NPC chief strategy officer, told Endpoints News by email, “We continue to call on ICER to stop producing this consistently flawed report that misleads stakeholders and risks driving harmful policy decisions.”

ALAMEDA, Calif.--( BUSINESS WIRE )-- Exelixis, Inc. (Nasdaq: EXEL) today announced that the U.S. Food and Drug Administration (FDA) has notified the company that the supplemental New Drug Application (sNDA) for cabozantinib (CABOMETYX ® ) for the treatment of adults with previously treated advanced pancreatic neuroendocrine tumors (pNET) and advanced extra-pancreatic NET (epNET) will be discussed at an Oncologic Drugs Advisory Committee (ODAC) meeting in March 2025. The sNDA is based on the final results of the phase 3 CABINET pivotal trial, conducted by the National Cancer Institute's National Clinical Trials Network, evaluating cabozantinib compared with placebo in advanced pNET and advanced epNET. In August 2024, Exelixis announced that the FDA granted orphan drug designation to cabozantinib for the treatment of pNET and assigned a Prescription Drug User Fee Act target action date of April 3, 2025. As announced in August 2023, the Alliance for Clinical Trials in Oncology independent Data and Safety Monitoring Board unanimously recommended that enrollment in the CABINET trial be stopped and randomized patients be unblinded to therapy with the allowance for crossover from placebo to cabozantinib due to the substantial improvement in progression-free survival (PFS) observed at this interim analysis. Final results from the enrolled patient population, which were presented at the 2024 European Society of Medical Oncology Congress and published concurrently in the New England Journal of Medicine , confirmed statistically significant and clinically meaningful improvements with cabozantinib versus placebo in the primary endpoint of PFS by blinded independent central review. Additional analyses supported consistency of benefit across all clinical subgroups examined, including primary tumor site, grade and prior systemic anticancer therapy. ODACs review and evaluate data regarding the safety and effectiveness of marketed and investigational human drug products for use in the treatment of cancer and make recommendations to the Commissioner of Food and Drugs. More general information about ODAC reviews can be found on the FDA website, here . The planned ODAC meeting is not related to the current approved indications for CABOMETYX in the U.S. About CABINET (Alliance A021602) CABINET (Randomized, Double-Blinded Phase III Study of CAB ozantinib versus Placebo I n Patients with Advanced NE uroendocrine T umors After Progression on Prior Therapy) is sponsored by the National Cancer Institute (NCI), part of the National Institutes of Health, and is being led and conducted by the NCI-funded Alliance for Clinical Trials in Oncology with participation from the NCI-funded National Clinical Trials Network as part of Exelixis’ collaboration through a Cooperative Research and Development Agreement with the NCI’s Cancer Therapy Evaluation Program. CABINET is a multicenter, randomized, double-blinded, placebo-controlled phase 3 pivotal trial that had enrolled a total of 298 patients in the U.S at the time of the final analysis. Patients were randomized 2:1 to cabozantinib (60 mg) or placebo in two separately powered cohorts (pNET, n=95; epNET, n=203). The epNET cohort included patients with the following primary tumor sites: gastrointestinal (GI) tract, lung, unknown primary sites and other. Each cohort was randomized separately and had its own statistical analysis plan. Patients must have had measurable disease per RECIST 1.1 criteria and must have experienced disease progression or intolerance after at least one U.S. FDA-approved line of prior therapy other than somatostatin analogs. The primary endpoint in each cohort was PFS per RECIST 1.1 by blinded independent central review. Secondary endpoints included overall survival, radiographic response rate and safety. More information about this trial is available at ClinicalTrials.gov . About Neuroendocrine Tumors (NET) NET are cancers that begin in the specialized cells of the body’s neuroendocrine system. 1 These cells have traits of both hormone-producing endocrine cells and nerve cells. 1 In the U.S., it is estimated that 161,000 to 192,000 people are living with unresectable, locally advanced or metastatic NET. 2 The number of people diagnosed with NET has been increasing in recent decades. 3 Functional NET release peptide hormones that can cause debilitating symptoms, like diarrhea, hypertension and flushing which may require focused treatment, while symptoms of non-functional NET are related primarily to tumor growth. 4,5 Most NET take years to develop and grow slowly, but eventually all patients with advanced or metastatic NET will develop refractory and progressing disease. 6,7 NET can develop in any part of the body, but most commonly start in the GI tract or in the lungs, where they have historically been referred to as carcinoid tumors and are more recently called epNET. 1 The five-year survival rates for advanced GI and lung NET tumors are 68% and 55%, respectively. 8,9 NET can also start in the pancreas, where they tend to be more aggressive, with a five-year survival rate of only 23% for advanced disease. 1,10 For advanced NET patients, treatment options include somatostatin analogs, chemotherapy, targeted therapy and peptide-receptor radionuclide therapy. 11 About CABOMETYX ® (cabozantinib) In the U.S., CABOMETYX tablets are approved as monotherapy for the treatment of patients with advanced renal cell carcinoma (RCC) and in combination with nivolumab for patients as a first-line treatment for patients with advanced RCC; for the treatment of patients with hepatocellular carcinoma (HCC) who have been previously treated with sorafenib, and; for adult and pediatric patients 12 years of age and older with locally advanced or metastatic differentiated thyroid cancer (DTC) that has progressed following prior VEGFR-targeted therapy and who are radioactive iodine-refractory or ineligible. CABOMETYX tablets have also received regulatory approvals in over 65 countries outside the U.S. and Japan, including the European Union. In 2016, Exelixis granted Ipsen Pharma SAS exclusive rights for the commercialization and further clinical development of cabozantinib outside of the U.S. and Japan. In 2017, Exelixis granted exclusive rights to Takeda Pharmaceutical Company Limited for the commercialization and further clinical development of cabozantinib for all future indications in Japan. Exelixis holds the exclusive rights to develop and commercialize cabozantinib in the U.S. CABOMETYX is not indicated as a treatment for NET. IMPORTANT SAFETY INFORMATION WARNINGS AND PRECAUTIONS Hemorrhage: Severe and fatal hemorrhages occurred with CABOMETYX. The incidence of Grade 3 to 5 hemorrhagic events was 5% in CABOMETYX patients in RCC, HCC, and DTC studies. Discontinue CABOMETYX for Grade 3 or 4 hemorrhage and prior to surgery as recommended. Do not administer CABOMETYX to patients who have a recent history of hemorrhage, including hemoptysis, hematemesis, or melena. Perforations and Fistulas: Fistulas, including fatal cases, occurred in 1% of CABOMETYX patients. GI perforations, including fatal cases, occurred in 1% of CABOMETYX patients. Monitor patients for signs and symptoms of fistulas and perforations, including abscess and sepsis. Discontinue CABOMETYX in patients who experience a Grade 4 fistula or a GI perforation. Thrombotic Events: CABOMETYX increased the risk of thrombotic events. Venous thromboembolism occurred in 7% (including 4% pulmonary embolism) and arterial thromboembolism in 2% of CABOMETYX patients. Fatal thrombotic events occurred in CABOMETYX patients. Discontinue CABOMETYX in patients who develop an acute myocardial infarction or serious arterial or venous thromboembolic events that require medical intervention. Hypertension and Hypertensive Crisis: CABOMETYX can cause hypertension, including hypertensive crisis. Hypertension was reported in 37% (16% Grade 3 and <1% Grade 4) of CABOMETYX patients. Do not initiate CABOMETYX in patients with uncontrolled hypertension. Monitor blood pressure regularly during CABOMETYX treatment. Withhold CABOMETYX for hypertension that is not adequately controlled with medical management; when controlled, resume at a reduced dose. Permanently discontinue CABOMETYX for severe hypertension that cannot be controlled with anti-hypertensive therapy or for hypertensive crisis. Diarrhea: Diarrhea occurred in 62% of CABOMETYX patients. Grade 3 diarrhea occurred in 10% of CABOMETYX patients. Monitor and manage patients using antidiarrheals as indicated. Withhold CABOMETYX until improvement to ≤ Grade 1, resume at a reduced dose. Palmar-Plantar Erythrodysesthesia (PPE): PPE occurred in 45% of CABOMETYX patients. Grade 3 PPE occurred in 13% of CABOMETYX patients. Withhold CABOMETYX until improvement to Grade 1 and resume at a reduced dose for intolerable Grade 2 PPE or Grade 3 PPE. Hepatotoxicity: CABOMETYX in combination with nivolumab can cause hepatic toxicity with higher frequencies of Grades 3 and 4 ALT and AST elevations compared to CABOMETYX alone. Monitor liver enzymes before initiation of and periodically throughout treatment. Consider more frequent monitoring of liver enzymes than when the drugs are administered as single agents. For elevated liver enzymes, interrupt CABOMETYX and nivolumab and consider administering corticosteroids. With the combination of CABOMETYX and nivolumab, Grades 3 and 4 increased ALT or AST were seen in 11% of patients. ALT or AST >3 times ULN (Grade ≥2) was reported in 83 patients, of whom 23 (28%) received systemic corticosteroids; ALT or AST resolved to Grades 0-1 in 74 (89%). Among the 44 patients with Grade ≥2 increased ALT or AST who were rechallenged with either CABOMETYX (n=9) or nivolumab (n=11) as a single agent or with both (n=24), recurrence of Grade ≥2 increased ALT or AST was observed in 2 patients receiving CABOMETYX, 2 patients receiving nivolumab, and 7 patients receiving both CABOMETYX and nivolumab. Withhold and resume at a reduced dose based on severity. Adrenal Insufficiency: CABOMETYX in combination with nivolumab can cause primary or secondary adrenal insufficiency. For Grade 2 or higher adrenal insufficiency, initiate symptomatic treatment, including hormone replacement as clinically indicated. Withhold CABOMETYX and/or nivolumab and resume CABOMETYX at a reduced dose depending on severity. Adrenal insufficiency occurred in 4.7% (15/320) of patients with RCC who received CABOMETYX with nivolumab, including Grade 3 (2.2%), and Grade 2 (1.9%) adverse reactions. Adrenal insufficiency led to permanent discontinuation of CABOMETYX and nivolumab in 0.9% and withholding of CABOMETYX and nivolumab in 2.8% of patients with RCC. Approximately 80% (12/15) of patients with adrenal insufficiency received hormone replacement therapy, including systemic corticosteroids. Adrenal insufficiency resolved in 27% (n=4) of the 15 patients. Of the 9 patients in whom CABOMETYX with nivolumab was withheld for adrenal insufficiency, 6 reinstated treatment after symptom improvement; of these, all (n=6) received hormone replacement therapy and 2 had recurrence of adrenal insufficiency. Proteinuria: Proteinuria was observed in 8% of CABOMETYX patients. Monitor urine protein regularly during CABOMETYX treatment. For Grade 2 or 3 proteinuria, withhold CABOMETYX until improvement to ≤ Grade 1 proteinuria; resume CABOMETYX at a reduced dose. Discontinue CABOMETYX in patients who develop nephrotic syndrome. Osteonecrosis of the Jaw (ONJ): ONJ occurred in <1% of CABOMETYX patients. ONJ can manifest as jaw pain, osteomyelitis, osteitis, bone erosion, tooth or periodontal infection, toothache, gingival ulceration or erosion, persistent jaw pain, or slow healing of the mouth or jaw after dental surgery. Perform an oral examination prior to CABOMETYX initiation and periodically during treatment. Advise patients regarding good oral hygiene practices. Withhold CABOMETYX for at least 3 weeks prior to scheduled dental surgery or invasive dental procedures, if possible. Withhold CABOMETYX for development of ONJ until complete resolution, resume at a reduced dose. Impaired Wound Healing: Wound complications occurred with CABOMETYX. Withhold CABOMETYX for at least 3 weeks prior to elective surgery. Do not administer CABOMETYX for at least 2 weeks after major surgery and until adequate wound healing. The safety of resumption of CABOMETYX after resolution of wound healing complications has not been established. Reversible Posterior Leukoencephalopathy Syndrome (RPLS): RPLS, a syndrome of subcortical vasogenic edema diagnosed by characteristic findings on MRI, can occur with CABOMETYX. Evaluate for RPLS in patients presenting with seizures, headache, visual disturbances, confusion, or altered mental function. Discontinue CABOMETYX in patients who develop RPLS. Thyroid Dysfunction: Thyroid dysfunction, primarily hypothyroidism, has been observed with CABOMETYX. Based on the safety population, thyroid dysfunction occurred in 19% of patients treated with CABOMETYX, including Grade 3 in 0.4% of patients. Patients should be assessed for signs of thyroid dysfunction prior to the initiation of CABOMETYX and monitored for signs and symptoms of thyroid dysfunction during CABOMETYX treatment. Thyroid function testing and management of dysfunction should be performed as clinically indicated. Hypocalcemia: CABOMETYX can cause hypocalcemia. Based on the safety population, hypocalcemia occurred in 13% of patients treated with CABOMETYX, including Grade 3 in 2% and Grade 4 in 1% of patients. Laboratory abnormality data were not collected in CABOSUN. In COSMIC-311, hypocalcemia occurred in 36% of patients treated with CABOMETYX, including Grade 3 in 6% and Grade 4 in 3% of patients. Monitor blood calcium levels and replace calcium as necessary during treatment. Withhold and resume at reduced dose upon recovery or permanently discontinue CABOMETYX depending on severity. Embryo-Fetal Toxicity: CABOMETYX can cause fetal harm. Advise pregnant women and females of reproductive potential of the potential risk to a fetus. Verify the pregnancy status of females of reproductive potential prior to initiating CABOMETYX and advise them to use effective contraception during treatment and for 4 months after the last dose. ADVERSE REACTIONS The most common (≥20%) adverse reactions are: CABOMETYX as a single agent: diarrhea, fatigue, PPE, decreased appetite, hypertension, nausea, vomiting, weight decreased, and constipation. CABOMETYX in combination with nivolumab: diarrhea, fatigue, hepatotoxicity, PPE, stomatitis, rash, hypertension, hypothyroidism, musculoskeletal pain, decreased appetite, nausea, dysgeusia, abdominal pain, cough, and upper respiratory tract infection. DRUG INTERACTIONS Strong CYP3A4 Inhibitors: If coadministration with strong CYP3A4 inhibitors cannot be avoided, reduce the CABOMETYX dosage. Avoid grapefruit or grapefruit juice. Strong CYP3A4 Inducers: If coadministration with strong CYP3A4 inducers cannot be avoided, increase the CABOMETYX dosage. Avoid St. John’s wort. USE IN SPECIFIC POPULATIONS Lactation: Advise women not to breastfeed during CABOMETYX treatment and for 4 months after the final dose. Hepatic Impairment: In patients with moderate hepatic impairment, reduce the CABOMETYX dosage. Avoid CABOMETYX in patients with severe hepatic impairment.
