Brief Summary

This phase II MATCH treatment trial identifies the effects of VS-6063 (defactinib) in patients whose cancer has a genetic change called NF2 mutation. Defactinib may block a protein called FAK, which may be needed for cancer cell growth when NF2 mutations are present. Researchers hope to learn if defactinib will shrink this type of cancer or stop its growth.

Conditions

Advanced Lymphoma; Refractory Multiple Myeloma; Advanced Malignant Solid Neoplasm; Hematopoietic and Lymphoid Cell Neoplasm; Refractory Lymphoma; Refractory Malignant Solid Neoplasm

Outcome Measures

Primary Outcomes (1)

• Objective Response Rate (ORR)

  ORR is defined as the percentage of patients whose tumors have a complete or partial response to treatment among analyzable patients. Objective response is defined consistent with Response Evaluation Criteria in Solid Tumors version 1.1, the Cheson (2014) criteria for lymphoma patients, and the Response Assessment in Neuro-Oncology criteria for glioblastoma patients. Details about how to define complete response and partial response can be found in the master protocol. 90% two-sided binomial exact confidence interval is calculated for ORR.

  Tumor assessments occurred at baseline, then every 2 cycles for the first 26 cycles and every 3 cycles thereafter until disease progression, up to 3 years post registration

Secondary Outcomes (2)

• 6-month Progression Free Survival (PFS)

  Assessed at baseline, then every 2 cycles for the first 26 cycles, and every 3 cycles thereafter until disease progression, up to 3 years post registration, from which 6-month PFS rate is determined

• Progression Free Survival

  Assessed at baseline, then every 2 cycles for the first 26 cycles and every 3 cycles thereafter until disease progression, up to 3 years post registration

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Patients must have met applicable eligibility criteria in the Master MATCH Protocol prior to registration to treatment subprotocol
• Patients must have a tumor that harbors an inactivating mutation in NF2
• Patients must have an electrocardiogram (ECG) within 8 weeks prior to treatment assignment and must have no clinically important abnormalities in rhythm, conduction or morphology of resting ECG (e.g. complete left bundle branch block, third degree heart block)
• Patients with known left ventricular dysfunction must have echocardiogram (ECHO) or a nuclear study (multigated acquisition scan \[MUGA\] or First Pass) within 4 weeks prior to registration to treatment and must not have left ventricular ejection fraction (LVEF) \< institutional lower limit of normal (LLN). If the LLN is not defined at a site, the LVEF must be \> 50% for the patient to be eligible
• Patients with history of hypertension should be adequately controlled (blood pressure \[BP\] \< 140/90) with appropriate anti-hypertensive therapy or diet

You may not qualify if:

• Patients must not have known hypersensitivity to VS-6063 (defactinib) or compounds of similar chemical or biologic composition
• Patients must not have a history of upper gastrointestinal (GI) bleeding, ulceration, or perforation within 12 months prior to the first dose of study drug
• Patients must not have known history of Gilbert's syndrome
• Patient must not have a known history of stroke or cerebrovascular accident within 6 months prior to the first dose of VS-6063 (defactinib)
• Patients must not have prior treatment with a FAK inhibitor (e.g., VS-6063 \[defactinib\] or GSK2256098) and must not be participating or have participated in the COMMAND trial of maintenance therapy of VS-6063 (defactinib) versus (vs.) placebo, for mesothelioma
• Patients must not be using drugs or foods that are known potent CYP3A4 or CYP2C9 inhibitors or inducers. Substrates of CYP3A4, 2C9, UGT1A1, P-gp, OATP1B1, and OATP1B3 should be used with caution
