- at Orange, California and other locations
- study startedestimated completion
This phase II trial studies how well the combination of XL184 (cabozantinib), nivolumab, and ipilimumab work in treating patients with poorly differentiated neuroendocrine tumors (i.e., neuroendocrine tumor that does not look like the normal tissue it arose from). Cabozantinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as nivolumab and ipilimumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving cabozantinib, nivolumab and ipilimumab may shrink the cancer.
A Phase 2 Study of XL184 (Cabozantinib) in Combination With Nivolumab and Ipilimumab for the Treatment of Poorly Differentiated Neuroendocrine Carcinomas
- To evaluate the overall response rate (ORR) associated with the combination of XL184 (cabozantinib), nivolumab, and ipilimumab in patients with advanced poorly-differentiated neuroendocrine carcinomas (NECs), after the failure of at least one line of prior therapy.
- To evaluate progression-free survival (PFS). II. To measure the safety and tolerability of the combination of XL184 (cabozantinib), nivolumab, and ipilimumab in patients with advanced, poorly-differentiated NECs.
III. To evaluate disease control rate (DCR). IV. To measure duration of response (DOR). V. To describe the tumor molecular profile using whole exome sequencing (WES) and correlate it with treatment outcome.
VI. To describe the tumor molecular profile using ribonucleic acid (RNA) sequencing (RNAseq) and correlate it with treatment outcome.
- To measure the tumor-infiltrating CD8+ T lymphocytes in pre- and on-treatment biopsies.
II. To measure tumor-infiltrating myeloid derived suppressor cells (MDSCs) in pre- and on-treatment biopsies.
III. To measure tumor-infiltrating tumor-associated macrophages (TAM) in the pre and on-treatment biopsies.
IV. To measure the expression of programmed death-ligand 1 (PD-L1) in tumor cells and infiltrating immune cells.
Patients receive cabozantinib s-malate orally (PO) once daily (QD) on days 1-21 of cycles 1-4 and days 1-28 of subsequent cycles, nivolumab intravenously (IV) over 30 minutes on day 1, and ipilimumab IV over 90 minutes on day 1 of cycles 1-4 only. Treatment repeats every 21 for 4 cycles then every 28 days for subsequent cycles in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up at 4 weeks, and then every 3 months thereafter.

- The effects of XL184 (cabozantinib), nivolumab, and ipilimumab on the developing human fetus are unknown. For this reason, women of child-bearing potential (WOCBP) and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation. WOCBP should use an adequate method to avoid pregnancy for 5 months after the last dose of study therapy. Women of childbearing potential must have a negative serum or urine pregnancy test (minimum sensitivity: 25 IU/L or equivalent units of human chorionic gonadotropin [hCG]) within 24 hours prior to the start of study therapy. Women must not be breastfeeding. Men who are sexually active with WOCBP must use any contraceptive method with a failure rate of < 1% per year. Men who receive study therapy and who are sexually active with WOCBP will be instructed to adhere to contraception for a period of 7 months after the last dose of study therapy. Women who are not of childbearing potential (i.e., who are postmenopausal or surgically sterile) as well as azoospermic men do not require contraception. WOCBP is defined as any female who has experienced menarche and who has not undergone surgical sterilization (hysterectomy or bilateral oophorectomy) or who is not postmenopausal. Menopause is defined clinically as 12 months of amenorrhea in a woman over 45 in the absence of other biological or physiological causes. In addition, women under the age of 55 must have a documented serum follicle stimulating hormone (FSH) level < 40 mIU/mL. WOCBP and men who are sexually active with WOCBP will be instructed to adhere to contraception for a period of 5 and 7 months, respectively, after the last dose of study therapy. These durations have been calculated using the upper limit of the half-life for nivolumab (25 days) and are based on the protocol requirement that WOCBP use contraception for 5 half-lives plus 30 days and men who are sexually active with WOCBP use contraception for 5 half-lives plus 90 days. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she (or the participating partner) must inform the treating physician immediately

- Therapeutic doses of LMWH are allowed in patients without known brain metastases who are on a stable dose of LMWH for at least 6 weeks before the first dose of study treatment, and who have had no clinically significant hemorrhagic complications from the anticoagulation regimen or the tumor
- Patients must not have had major surgery (e.g., gastrointestinal [GI] surgery or removal or biopsy of brain metastasis) within 4 weeks before first dose of study treatment. Complete wound healing from major surgery must have occurred 1 month before the first dose of study treatment and from minor surgery (e.g., simple excision or tooth extraction) at least 10 days before the first dose. Patients with clinically relevant ongoing complications from prior surgery are not eligible
- Patients must not have received cytotoxic chemotherapy (including investigational cytotoxic chemotherapy) or biologic agents (e.g., cytokines or antibodies) within 4 weeks, or nitrosoureas/ mitomycin C within 4 weeks, before the first dose of study treatment. Patients may continue on bone-modifying agents (denosumab or bisphosphonates) with caution
- Patients who have not recovered to baseline from adverse events due to prior anti-cancer therapy (i.e., have residual toxicities > grade 1) according to Common Terminology Criteria for Adverse Events (CTCAE) version (v)0.5 unless the adverse events (AEs) are clinically nonsignificant and/or stable on supportive therapy, with the exception of alopecia
- Patients who are receiving any other investigational agents. Patients must not have received any other type of investigational agent within 4 weeks before the first dose of study treatment to be eligible
- Patients must not have a corrected QT interval calculated by the Fridericia formula (QTcF) > 500 msec by electrocardiogram (EKG) within 28 days before the first dose of study treatment
- Note: If a single EKG shows a QTcF with an absolute value > 500 msec, two additional EKGs at intervals of approximately 3 min must be performed within 30 min after the initial EKG, and the average of these three consecutive results for QTcF will be used to determine eligibility
- Patients should not have known, untreated brain metastases or leptomeningeal metastases because of poor prognosis and concerns that progressive neurologic dysfunction could confound the evaluation of neurologic and other adverse events
- History of allergic reactions attributed to compounds of similar chemical or biologic composition to agents used in study
- Patients must not have a history of severe hypersensitivity reactions to any monoclonal antibodies
- Patients must not require concomitant treatment with strong CYP3A4 inducers (e.g., dexamethasone, phenytoin, carbamazepine, rifampin, rifabutin, rifapentine, phenobarbital, or St. John's wort). Because lists of these agents are constantly changing, it is important to regularly consult a frequently-updated medical reference. As part of the enrollment/informed consent procedures, patients will be counseled on the risk of interactions with other agents, and what to do if new medications need to be prescribed or if the patient is considering a new over-the-counter medicine or herbal product

- GI disorders including those associated with a high risk of perforation or fistula formation:
- The patient has evidence of tumor invading the GI tract, active peptic ulcer disease, inflammatory bowel disease (e.g., Crohn's disease), diverticulitis, cholecystitis, symptomatic cholangitis or appendicitis, acute pancreatitis, acute obstruction of the pancreatic duct or common bile duct, or gastric outlet obstruction.
- Abdominal fistula, GI perforation, bowel obstruction, or intra-abdominal abscess within 6 months before first dose. Complete healing of an intra-abdominal abscess must be confirmed before first dose.
- Clinically significant hematuria, hematemesis, or hemoptysis or other history of significant bleeding (e.g., pulmonary hemorrhage) within 12 weeks before first dose.
- Cavitating pulmonary lesion(s) or known endotracheal or endobronchial disease manifestation.
- Lesions invading or encasing any major blood vessels.
- Other clinically significant disorders that would preclude safe study participation.
- Serious non-healing wound/ulcer/bone fracture.
- Uncompensated/symptomatic hypothyroidism.
- Moderate to severe hepatic impairment (Child-Pugh B or C).
- Cardiovascular disorders:
- Patients with psychiatric illness/social situations that would limit compliance with study requirements
- Pregnant women are excluded from this study because XL184 (cabozantinib) has the potential for teratogenic or abortifacient effects, and the effects of nivolumab and ipilimumab on the developing fetus are not well known. Because there is an unknown but potential risk for AEs in nursing infants secondary to treatment of the mother, breastfeeding must be discontinued if the mother is treated with XL184 (cabozantinib), nivolumab, or ipilimumab
- Patients with active autoimmune disease or history of autoimmune disease that might recur, which may affect vital organ function or require immune suppressive treatment including high dose systemic corticosteroids, should be excluded. These include but are not limited to: immune-related neurologic disease, such as multiple sclerosis, autoimmune (demyelinating) neuropathy, Guillain-Barre syndrome, or myasthenia gravis; systemic autoimmune disease such as systemic lupus erythematosus (SLE), connective tissue diseases, scleroderma, inflammatory bowel disease (IBD), Crohn's, ulcerative colitis, or autoimmune hepatitis. Patients with a history of toxic epidermal necrolysis (TEN), Stevens-Johnson syndrome, or phospholipid syndrome should be excluded because of the risk of recurrence or exacerbation of disease. Patients with vitiligo, type I diabetes mellitus (DM), or endocrine deficiencies (e.g., thyroiditis) managed with replacement hormones, including physiologic corticosteroids, are eligible. Patients with rheumatoid arthritis and other arthropathies, Sjogren's syndrome and psoriasis controlled with topical medication, and patients with positive serology, (e.g., antinuclear antibodies [ANA] or anti-thyroid antibodies) should be evaluated for the presence of target organ involvement and potential need for systemic treatment but should otherwise be eligible
