  Purpose

The purpose of this phase II study is to find out what effects cabozantinib (XL184) has, good and/or bad, in patients whose tumors have a gene called KIF5B/RET.

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.

KIF5B/RET is an abnormal gene that leads to lung cancer cell growth. Cabozantinib is an oral medicine that inhibits the effects of this gene. 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 your 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.

Primary Outcome Measures:
  • response rate (ORR) [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
    by RECIST v1.1 criteria to cabozantinib in patients with advanced NSCLC who have tested positive for RET Fusion


Secondary Outcome Measures:
  • progression-free survival (PFS) [ Time Frame: 3 years ] [ Designated as safety issue: No ]
    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.

  • overall survival (OS) [ Time Frame: 3 years ] [ Designated as safety issue: No ]
    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.

  • safety [ Time Frame: 3 years ] [ Designated as safety issue: Yes ]
    Observed toxicities will be individually tabulated according to CTCAE version 4.0 and summarized using descriptive statistics.

Estimated Primary Completion Date: July 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Cabozantinib
To perform a single-arm Simon two-stage phase II study of a RET inhibitor, cabozantinib, in patients who are KIF5B/RET positive with NSCLC. This will be the first clinical study of cabozantinib in KIF5B/RET positive NSCLC patients.
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.

  • The subject is capable of understanding and complying with the protocol requirements and has signed the informed consent document. Sexually active subjects (men and women) must agree to use medically accepted barrier methods of contraception (eg, male or female condom) during the course of the study and for 4 months after the last dose of study drug(s), even if oral contraceptives are also used. All subjects of reproductive potential must agree to use both a barrier method and a second method of birth control. Women of childbearing potential must have a negative pregnancy test at screening.
  • Women of childbearing potential include women who have experienced menarche and who have not undergone successful surgical sterilization (hysterectomy, bilateral tubal ligation, or bilateral oophorectomy) or are not postmenopausal.

Postmenopause is defined as amenorrhea ≥ 12 consecutive months. Note:

women who have been amenorrheic for 12 or more months are still considered to be of childbearing potential if the amenorrhea is possibly due to prior chemotherapy, antiestrogens, ovarian suppression or any other reversible reason.
