Summary
Brief summary (as posted)
This phase II MATCH treatment trial tests how well GDC-0449 (vismodegib) works for treating patients with solid tumors, lymphoma, or multiple myeloma that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced) or that does not respond to treatment (refractory) and who have a smoothened or patched 1 genetic mutation. Vismodegib is a type of medication called a hedgehog signaling pathway antagonist and works by blocks a type of protein involved in tissue growth and repair and may block the growth of cancer cells.

- label
- Treatment (Vismodegib)
- description
- Patients receive vismodegib orally (PO) daily (QD) on days 1-28. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients undergo ECHO or nuclear study during screening, tumor biopsy on study and CT scan, MRI and blood sample collection throughout the study.

Primary outcomes (1)
- measure
- Objective Response Rate (ORR)
- timeFrame
- 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
- 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.

Inclusion Criteria: * Patients must have met applicable eligibility criteria in the Master MATCH Protocol EAY131/ NCI-2015-00054 prior to registration to treatment subprotocol * Patients must fulfill all eligibility criteria outlined in section 3.1 of MATCH Master protocol (excluding section 3.1.6) at the time of registration to treatment step (step 1, 3, 5, 7) * Patients must have activating mutations of smoothened (SMO) or deleterious Patched 1 (PTCH1) as determined via the MATCH Master protocol and described in appendix II. See appendix II for information on the smoothened (SMO) or patched 1 (PTCH1) mutations and corresponding levels of evidence * Patient must not have basal cell carcinoma * Patients must have an electrocardiogram (ECG) within 8 weeks prior to treatment assignment and must have NONE of the following cardiac criteria: * No clinically unstable abnormalities in rhythm, conduction or morphology of resting ECG e.g. complete left bundle branch block, third degree heart block * No factors that increase the risk of corrected QT (QTc) prolongation or risk of arrhythmic events such as congenital long QT syndrome, family history of long QT syndrome or unexplained sudden death under 40 years of age * Patients with known left ventricular dysfunction must have ECHO or nuclear study (multigated acquisition \[MUGA\] scan 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 must not have known hypersensitivity to GDC-0449 (vismodegib) or compounds of similar chemical or biologic composition * Women of childbearing potential and men who are sexually active must agree to use adequate contraception defined as appropriate double barrier method of birth control (such as female use of a diaphragm, intrauterine device (IUD), sponge and spermicide, in addition to the male use of a condom or involve female use of prescribed "birth control pills" or a prescribed birth control implant). Both double barrier contraception and birth control pills or implants must be used for at least one week prior to the start of the study and continue for 24 months after completion of study for women, and 3 months after completion of study for men
