Cabozantinib and Nivolumab for the Treatment of Advanced Carcinoid Tumors

Trial Status: Active

This phase II trial studies how well cabozantinib and nivolumab work in treating patients with carcinoid tumors that have spread to other places in the body (advanced). Carcinoid tumor is another term used to refer to neuroendocrine tumors that arise in organs such as the gastrointestinal tract, lungs, or thymus. Cabozantinib works by blocking the growth of new blood vessels (angiogenesis) that help to feed a tumor. In addition to blocking the formation of new blood cells in tumors, cabozantinib also blocks pathways that may be responsible for allowing tumor cells to become resistant to other anti-angiogenic cancer drugs. Nivolumab works by attaching to and blocking a molecule called PD-1. PD-1 is a protein that is present on different types of cells in the immune system and controls parts of the immune system by shutting it down. Antibodies that block PD-1 may prevent PD-1 from shutting down the immune system, thus allowing it to recognize and help the body destroy the tumor cells. The purpose of this study is to test the safety and effectiveness of cabozantinib in combination with nivolumab in treating advanced carcinoid tumors.

  • Participant has an active infection requiring IV antibiotics
  • Any active, known, or suspected autoimmune disease. Participants with type I diabetes mellitus, hypothyroidism only requiring hormone replacement, skin disorders (such as vitiligo, psoriasis, or alopecia) not requiring systemic treatment, or conditions not expected to recur in the absence of an external trigger (e.g. celiac disease) are permitted to enroll
  • Patient has a medical condition that requires chronic systemic steroid therapy or on any other form of immunosuppressive medication. Adrenal replacement steroid disease are permitted in the absence of autoimmune disease
  • The participant is known to be positive for the human immunodeficiency virus (HIV), hepatitis B surface antigen (HepBsAg), or hepatitis C virus (HCV) ribonucleic acid (RNA). HIV-positive participants with non-detectable viral loads on combination antiretroviral therapy are ineligible because of the potential for pharmacokinetic interactions with cabozantinib and nivolumab
  • The participant has received a live vaccine within 28 days prior to the first dose of trial treatment and while participating in the trial. Examples of live vaccines include, but are not limited to, the following: measles, mumps, rubella, varicella/zoster, yellow fever, rabies, Bacillus Calmette-Guerin (BCG), and typhoid vaccine. The use of the inactivated seasonal influenza vaccine (Fluzone) is allowed
  • Pregnant or lactating females are excluded from this study because cabozantinib and nivolumab are agents with the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with cabozantinib and nivolumab, breastfeeding should be discontinued if the mother is treated with cabozantinib and nivolumab. These potential risks may also apply to other agents used in this study
  • Sexually active fertile subjects and their partners must agree to use medically accepted methods of contraception (e.g., barrier methods, including male condom, female condom, or diaphragm with spermicidal gel) during the course of the study and following treatment. Women of childbearing potential receiving nivolumab will be instructed to adhere to contraception for a period of 5 months after the last dose of nivolumab. Men receiving nivolumab and who are sexually active with women of child bearing potential (WOCBP) will be instructed to adhere to contraception for a period of 7 months after the last dose of nivolumab. Contraception must be used for 4 months after last dose of cabozantinib

V. To evaluate overall survival of patients with advanced carcinoid tumors treated with the combination of cabozantinib and nivolumab.

EXPLORATORY OBJECTIVES:

I. To explore whether baseline tumor immune cell infiltration and PD-L1 and PD-L2 staining correlates with response to therapy.

II. To explore whether changes in circulating immune cell profile correlates with response to therapy.

III. To explore whether changes in the level of angiogenic and inflammatory blood biomarkers during therapy correlate with efficacy of therapy.
