Study Description

Brief Summary:

The purpose of this phase II study is to find out what effects cabozantinib (XL184) has, good and/or bad, in patients whose tumors one of the following gene changes RET, ROS1, or NTRK fusion, or increased MET or AXL activity.

A phase II study looks at how effective a medication is at treating a specific type of cancer and collects information on the side effects of the study treatment.

RET, ROS1, or NTRK fusion or increased MET or AXL activity gene leads to lung cancer cell growth. Cabozantinib is an oral medicine that inhibits of RET, ROS1, NTRK, MET, and AXL. In addition, this drug interferes with other cell pathways that also cause cancer cells to grow, form new blood vessels, and spread to other organs of the body. The goal of using cabozantinib is to shrink the cancer and to prevent it from growing

Cabozantinib has been studied and shown to cause cancer shrinkage in other cancers such as medullary thyroid cancer and prostate cancer. We thus have a good idea of what side-effects it causes and can anticipate them.

Arms and Interventions

Arm

Intervention/treatment

Experimental: Cabozantinib; This will be a single-institution, open label, two-stage, single agent trial of cabozantinib in patients with advanced NSCLCs.atients in GROUP A will have tumors with a RET fusion. Patients in GROUP B will have tumors with an NTRK fusion, or MET or AXL overexpression, amplication, or mutatation. Patients in GROUP C will have tumors with a ROS1 fusion. Patients in GROUP D will have tumors with a RET fusion and have progressed on a selective RET TKI.

Drug: Cabozantinib; Patients will receive cabozantinib at an initial dose of 60 mg orally daily. The drug is taken continuously over a period of 28 days (4 weeks), which constitutes one treatment cycle. Dose modifications for drug toxicity are permitted as per a prescribed algorithm. During the Treatment Period subjects will receive cabozantinib until either disease progression, the occurrence of unacceptable drug-related toxicity or for other reason(s) for subject withdrawal.

Outcome Measures

Primary Outcome Measures :

1. objective response rate (ORR) (Group A) [ Time Frame: 12 weeks ]
   by RECIST v1.1 criteria to cabozantinib in patients with advanced NSCLC who have tested positive for RET Fusion
2. objective response rate (ORR) (Group B) [ Time Frame: 12 weeks ]
   by RECIST v1.1 criteria to cabozantinib in patients with advanced NSCLC whose tumors test positive for a ROS1 or NTRK fusion or MET or AXL overexpression, amplification, or mutation.

Secondary Outcome Measures :

1. progression-free survival (PFS) (Group A) [ Time Frame: 3 years ]
   Progression-free (PFS) and overall survival (OS) will be calculated using Kaplan-Meyer estimators starting from the time of treatment initiation. For PFS, patients alive without evidence of progression at the end of the study will be censored at the time of the last available follow-up. For OS, patients alive at the end of the study will be censored at the time of the last available follow-up.
2. overall survival (OS) (Group A) [ Time Frame: 3 years ]
   Progression-free (PFS) and overall survival (OS) will be calculated using Kaplan-Meyer estimators starting from the time of treatment initiation. For PFS, patients alive without evidence of progression at the end of the study will be censored at the time of the last available follow-up. For OS, patients alive at the end of the study will be censored at the time of the last available follow-up.
3. safety (Group A, B, C & D) [ Time Frame: 3 years ]
   Observed toxicities will be individually tabulated according to CTCAE version 4.0 and summarized using descriptive statistics.
4. progression-free survival (PFS) (Group B, C & D) [ Time Frame: 3 years ]
   Progression-free (PFS) and overall survival (OS) will be calculated using Kaplan-Meyer estimators starting from the time of treatment initiation. For PFS, patients alive without evidence of progression at the end of the study will be censored at the time of the last available follow-up. For OS, patients alive at the end of the study will be censored at the time of the last available follow-up with advanced NSCLCs whose tumors test positive for a ROS1 or NTRK fusion or MET or AXL overexpression or amplification who were treated with cabozantinib.
5. overall survival (OS) (Group B, C & D) [ Time Frame: 3 years ]
   Progression-free (PFS) and overall survival (OS) will be calculated using Kaplan-Meyer estimators starting from the time of treatment initiation. For PFS, patients alive without evidence of progression at the end of the study will be censored at the time of the last available follow-up. For OS, patients alive at the end of the study will be censored at the time of the last available follow-up with advanced NSCLCs whose tumors test positive for a ROS1 or NTRK fusion or MET or AXL overexpression or amplification who were treated with cabozantinib.
