Clinical Trial Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

The data described in the WARNINGS AND PRECAUTIONS section and below reflect exposure to CABOMETYX as a single agent at 60 mg orally once daily until disease progression or unacceptable toxicity in 409 patients with RCC enrolled in a randomized, active-controlled trial (CABOSUN, METEOR), 467 patients with HCC enrolled in a randomized, placebo- controlled trial (CELESTIAL), 125 patients with DTC enrolled in a randomized, placebo- controlled trial (COSMIC-311), 195 patients with pNET or epNET enrolled in a randomized, placebo-controlled trial (CABINET), and at 40 mg CABOMETYX in combination with nivolumab 240 mg/m ²every 2 weeks, in 320 patients with RCC enrolled in a randomized, active- controlled trial (CHECKMATE-9ER).

Renal Cell Carcinoma

METEOR

The safety of CABOMETYX was evaluated in METEOR, a randomized, open-label trial in which 331 patients with advanced renal cell carcinoma received CABOMETYX 60 mg once daily and 322 patients received everolimus 10 mg once daily until disease progression or unacceptable toxicity. Patients on both arms who had disease progression could continue treatment at the discretion of the investigator [see Clinical Studies (14) ] . The median duration of treatment was 7.6 months (range 0.3 – 20.5) for patients receiving CABOMETYX and 4.4 months (range 0.21 – 18.9) for patients receiving everolimus.

Adverse reactions which occurred in ≥ 25% of CABOMETYX-treated patients, in order of decreasing frequency, were: diarrhea, fatigue, nausea, decreased appetite, palmar-plantar erythrodysesthesia (PPE), hypertension, vomiting, weight decreased, and constipation. Grade 3-4 adverse reactions and laboratory abnormalities which occurred in ≥ 5% of patients were hypertension, diarrhea, fatigue, PPE, hyponatremia, hypophosphatemia, hypomagnesemia, lymphopenia, anemia, hypokalemia, and increased GGT.

The dose was reduced in 60% of patients receiving CABOMETYX and in 24% of patients receiving everolimus. Twenty percent (20%) of patients received CABOMETYX 20 mg once daily as their lowest dose. The most frequent adverse reactions leading to dose reduction in patients treated with CABOMETYX were: diarrhea, PPE, fatigue, and hypertension. Adverse reactions leading to dose interruption occurred in 70% patients receiving CABOMETYX and in 59% patients receiving everolimus. Adverse reactions led to study treatment discontinuation in 10% of patients receiving CABOMETYX and in 10% of patients receiving everolimus. The most frequent adverse reactions leading to permanent discontinuation in patients treated with CABOMETYX were decreased appetite (2%) and fatigue (1%).

CABOSUN

The safety of CABOMETYX was evaluated in CABOSUN, a randomized, open-label trial in patients with advanced renal cell carcinoma, in which 78 patients received CABOMETYX 60 mg once daily and 72 patients received sunitinib 50 mg once daily (4 weeks on treatment followed by 2 weeks off), until disease progression or unacceptable toxicity [see Clinical Studies (14.1) ] . The median duration of treatment was 6.5 months (range 0.2 – 28.7) for patients receiving CABOMETYX and 3.1 months (range 0.2 – 25.5) for patients receiving sunitinib.

Within 30 days of treatment, there were 4 deaths in patients treated with CABOMETYX and 6 deaths in patients treated with sunitinib. Of the 4 patients treated with CABOMETYX, 2 patients died due to gastrointestinal perforation, 1 patient had acute renal failure, and 1 patient died due to clinical deterioration. All Grade 3-4 adverse reactions were collected in the entire safety population. The most frequent Grade 3-4 adverse reactions (≥5%) in patients treated with CABOMETYX were hypertension, diarrhea, hyponatremia, hypophosphatemia, PPE, fatigue, increased ALT, decreased appetite, stomatitis, pain, hypotension, and syncope.

The median average daily dose was 50.3 mg for CABOMETYX and 44.7 mg for sunitinib (excluding scheduled sunitinib non-dosing days). The dose was reduced in 46% of patients receiving CABOMETYX and in 35% of patients receiving sunitinib. The dose was held in 73% of patients receiving CABOMETYX and in 71% of patients receiving sunitinib. Based on patient disposition, 21% of patients receiving CABOMETYX and 22% of patients receiving sunitinib discontinued due to an adverse reaction.

CHECKMATE-9ER

The safety of CABOMETYX with nivolumab was evaluated in CHECKMATE-9ER, a randomized, open-label study in patients with previously untreated advanced RCC [see Clinical Studies (14.1) ] . Patients received CABOMETYX 40 mg orally once daily with nivolumab 240 mg over 30 minutes every 2 weeks (n=320) or sunitinib 50 mg daily, administered orally for 4 weeks on treatment followed by 2 weeks off (n=320) [see Clinical Studies (14.1) ] . CABOMETYX could be interrupted or reduced to 20 mg daily or 20 mg every other day. The median duration of treatment was 14 months (range: 0.2 to 27 months) in CABOMETYX and nivolumab-treated patients. In this trial, 82% of patients in the CABOMETYX and nivolumab arm were exposed to treatment for >6 months and 60% of patients were exposed to treatment for >1 year.

Serious adverse reactions occurred in 48% of patients receiving CABOMETYX and nivolumab. The most frequent (≥2%) serious adverse reactions were diarrhea, pneumonia, pneumonitis, pulmonary embolism, urinary tract infection, and hyponatremia. Fatal intestinal perforations occurred in 3 (0.9%) patients.

Adverse reactions leading to discontinuation of either CABOMETYX or nivolumab occurred in 20% of patients: 8% CABOMETYX only, 7% nivolumab only, and 6% both drugs due to the same adverse reaction at the same time. Adverse reactions leading to dose interruption or reduction of either CABOMETYX or nivolumab occurred in 83% of patients: 46% CABOMETYX only, 3% nivolumab only, and 21% both drugs due to the same adverse reaction at the same time, and 6% both drugs sequentially.

The most common adverse reactions reported in ≥20% of patients treated with CABOMETYX and nivolumab were diarrhea, fatigue, hepatotoxicity, PPE, stomatitis, rash, hypertension, hypothyroidism, musculoskeletal pain, decreased appetite, nausea, dysgeusia, abdominal pain, cough, and upper respiratory tract infection.

Neuroendocrine Tumors

Pancreatic Neuroendocrine Tumors (pNET)

The safety of CABOMETYX was evaluated in adult patients with unresectable, locally advanced or metastatic, well-differentiated neuroendocrine tumors in the CABINET trial [see Clinical Studies (14.4) ] . Patients received CABOMETYX 60 mg (n=63) or placebo orally (n=31) once daily until disease progression or unacceptable toxicity. Patients with pNET were required to have disease progression after prior treatment with at least one FDA approved therapy (everolimus, sunitinib or lutetium Lu 177 dotatate), other than somatostatin analogs. The median duration of treatment was 8.3 months (range: 0.1 to 37.8) for patients receiving CABOMETYX and 2.9 months (range: 0.1 to 11.2) for patients receiving placebo.

The median age of patients who received CABOMETYX was 60 years (range: 29 to 79), 57% were male, 86% were White, 6% were Asian, 3.2% were Black, 1.6% were American Indian or Alaska Native, 1.6% were Native Hawaiian or Other Pacific Islanders, and 3.2% were Hispanic or Latino.

Serious adverse reactions occurred in 46% of patients who received CABOMETYX. Serious adverse reactions in ≥2% of patients included thromboembolic events (10%), vomiting (6%), sepsis (4.8%), nausea (4.8%), hypoxia (4.8%), hemorrhage (3.2%), abdominal pain (3.2%), musculoskeletal pain (3.2%), blood bilirubin increased (3.2%), fatigue (3.2%), hyperkalemia (3.2%), and hypertension (3.2%).

Extra-Pancreatic Neuroendocrine Tumors (epNET)

The safety of CABOMETYX was evaluated in adult patients with unresectable, locally advanced or metastatic, well-differentiated neuroendocrine tumors in the CABINET trial [see Clinical Studies (14.4) ] . Patients received CABOMETYX 60 mg (n=132) or placebo (n=67) orally once daily until disease progression or unacceptable toxicity. Patients with epNET were required to have disease progression after prior treatment with at least one FDA approved therapy (everolimus or lutetium Lu 177 dotatate), other than somatostatin analogs. The median duration of treatment was 5.4 months (range 0.1 to 32.4) for patients receiving CABOMETYX and 2.8 months (range 0.5 to 22.8) for patients receiving placebo.

The median age was 66 years (range 28 to 86), 55% were female, 86% were White, 7% were Black, 2.3% were Asian, 5% had unknown race or race not reported, and 6% were Hispanic or Latino.

Serious adverse reactions occurred in 44% of patients who received CABOMETYX. Serious adverse reactions in ≥2% included hypertension (6%), abdominal pain (5%), musculoskeletal pain (5%), diarrhea (3.0%), vomiting (3.0%), blood bilirubin increased (3.0%), thromboembolic events (3.0%), nausea (2.3%), hemoglobin decreased (2.3%), muscular weakness (2.3%), fatigue (2.3%), sepsis (2.3%), and syncope (2.3%). Fatal adverse reactions occurred in 4.5% of patients who received CABOMETYX, including hepatic failure, multi-organ dysfunction, gastrointestinal hemorrhage, cardiac arrest, ruptured ascending aortic aneurysm, and sudden death not otherwise specified, occurring in one patient each.

Permanent discontinuation of CABOMETYX due to an adverse reaction occurred in 28% of patients receiving CABOMETYX. Adverse reactions which resulted in permanent discontinuation of CABOMETYX included diarrhea, fatigue, increased AST, increased ALT, blood bilirubin increased, rash, thromboembolic events, hypertension, increased ALP, nausea, and stomatitis.

The median average daily dose was 42.9 mg for CABOMETYX. Dosage interruptions of CABOMETYX due to an adverse reaction occurred in 81% of patients. Adverse reactions which required dosage interruption in ≥5% of patients included diarrhea, fatigue, rash, hypertension, nausea, stomatitis, abdominal pain, increased AST, vomiting, and musculoskeletal pain.

Dose reductions of CABOMETYX due to an adverse reaction occurred in 38% of patients. Adverse reactions which required dose reductions in ≥5% of patients included rash, fatigue, diarrhea, and hypertension.

The most common adverse reactions occurring in ≥20% of CABOMETYX-treated patients were fatigue, increased AST, diarrhea, hypertension, increased ALT, platelet count decreased, rash, stomatitis, nausea, white blood cell count decreased, neutrophil count decreased, musculoskeletal pain, dysgeusia, hypothyroidism, decreased appetite, hemoglobin decreased, hyperglycemia, abdominal pain, increased ALP, lymphocyte count decreased, weight decreased, blood creatinine increased, hypoalbuminemia, blood bilirubin increased, hypocalcemia, hypokalemia, and hypomagnesemia.
