Testing VS-6063 (Defactinib) as a Potential Targeted Treatment in Cancers With NF2 Genetic Changes (MATCH-Subprotocol U)

Found through the registry condition index, not selected as a treatment recommendation. This discovery collection was restricted to studies with posted results.

Phase: PHASE2
Status at capture: ACTIVE NOT RECRUITING
Registry last update: 2026-05-07

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.

Who could take part

eligibility Criteria: Inclusion Criteria: * 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 Exclusion Criteria: * 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

primary Outcomes

description
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.
measure
Objective Response Rate (ORR)
time Frame
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

description
Progression free survival is defined as time from treatment start date to date of progression or death from any cause, whichever occurs first. Disease progression was evaluated using the 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. Please refer to the protocol for detailed definitions of disease progression. 6 month PFS rate was estimated using the Kaplan-Meier method, which can provide a point estimate for any specific time point.
measure
6-month Progression Free Survival (PFS)
time Frame
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

Full study description

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.
detailed Description: PRIMARY OBJECTIVE: I. To evaluate the proportion of patients with objective response (OR) to targeted study agent(s) in patients with advanced refractory cancers/lymphomas/multiple myeloma. SECONDARY OBJECTIVES: I. To evaluate the proportion of patients alive and progression free at 6 months of treatment with targeted study agent in patients with advanced refractory cancers/lymphomas/multiple myeloma. II. To evaluate time until death or disease progression. III. To identify potential predictive biomarkers beyond the genomic alteration by which treatment is assigned or resistance mechanisms using additional genomic, ribonucleic acid (RNA), protein and imaging-based assessment platforms. IV. To assess whether radiomic phenotypes obtained from pre-treatment imaging and changes from pre- through post-therapy imaging can predict objective response and progression free survival and to evaluate the association between pre-treatment radiomic phenotypes and targeted gene mutation patterns of tumor biopsy specimens. OUTLINE: Patients receive defactinib hydrochloride (defactinib) orally (PO) 400 mg twice daily (BID) on days 1-28. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up every 3 months if less than 2 years from study entry, and then every 6 months for year 3 from study entry. THE MATCH SCREENING TRIAL: Please see NCT02465060 for information on the MATCH Screening Protocol and applicable documents.
