Melanoma Clinical Trial

Study of XL888 With Vemurafenib for Patients With Unresectable BRAF Mutated Stage III/IV Melanoma

Summary

This is a multi-cohort, dose-escalation study of XL888 with a fixed dose of vemurafenib. New dose escalation or de-escalation cohorts will be assigned by the Principal Investigator (PI) with discussion with appropriate co-investigators once safety and tolerability is known for a given cohort in accordance to dose escalation rules. Participants will be defined to be enrolled within a cohort upon receipt of first dose of XL888/vemurafenib.

Full Description

In this study, the investigational drug XL888 will be given along with the drug vemurafenib. The investigators want to learn more about the safety and side effects of XL888 and hope to find out what dose of the drug can be given safely without serious side effects. Based on research done in a laboratory on tissue samples (cells collected from living things), the researchers think that XL888 might help to make vemurafenib work to fight cancer cells in the body for a longer period of time.

Eligibility Criteria

Inclusion Criteria:

Must have cytologically or histologically-confirmed unresectable melanoma that harbors a BRAF V600 E or K mutation determined by pyrosequencing assay or equivalent genotyping assay in a Clinical Laboratory Improvement Amendments (CLIA) certified laboratory, meeting one of the following American Joint Committee on Cancer (AJCC) staging criteria:

AJCC Stage IV (Tany, Nany, M1a, b, or c)
AJCC Stage III B or C with unresectable nodal/locoregional involvement

Adequate hepatic, renal, and bone marrow function as defined by the following parameters obtained within 2 weeks prior to initiation of study treatment:

Hematologic Criteria: leukocytes ≥3,000/mcL; absolute neutrophil count ≥1,500/mcL; platelets ≥100,000/mcL
Renal Criteria: serum creatinine within normal institutional limits or a creatinine clearance ≥60 mL/min for patients with creatinine levels above institutional normal
Hepatic Criteria: aspartate aminotransferase (AST)/alanine transaminase (ALT) ≤2.5 X institutional upper limit of normal; if liver metastasis present, then AST/ALT may be less than or equal to 5 times the upper limit of normal
Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1
Willing to give written informed consent per institutional guidelines and must be able to adhere to dose and visit schedules
Female and male participants must agree to use a medically acceptable method of birth control prior to screening and agree to continue its use throughout the study. Females of childbearing potential should be counseled in the appropriate use of birth control while on this study.
Treatment-naïve and previously treated patients will be included; however, patients may not have received a BRAF or HSP90 inhibitor in the past.
Patients must be at least 4 weeks from any prior systemic therapy (6 weeks for nitrosoureas or mitomycin C), surgery or radiation.
Must have measurable disease as defined by RECIST 1.1

Exclusion Criteria:

Females who are pregnant, intend to become pregnant or are nursing. Females with child-bearing potential must have a negative pregnancy test within one week of enrollment.
Previously treated with BRAF or HSP90 inhibitor therapy
Patients who have had chemotherapy or radiotherapy within 4 weeks (6 weeks for nitrosoureas or mitomycin C) prior to entering the study or those who have not recovered from adverse events due to agents administered more than 4 weeks earlier.
Patients who are receiving any other investigational agents.
History of allergic reactions attributed to compounds of similar chemical or biologic composition (i.e. ethanol) to XL888 or vemurafenib (i.e., ethanol).
Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, uncontrolled or symptomatic cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements
HIV-positive patients on combination antiretroviral therapy are ineligible because of the potential for pharmacokinetic interactions with XL888 and vemurafenib.
Untreated or uncontrolled brain metastases or evidence of leptomeningeal disease. Brain metastases that have been appropriately treated with radiation and/or surgery will be allowed as long as the central nervous system (CNS) disease has been stable for at least 4 weeks post-treatment.
Must be at least 3 years from any prior malignancy and have no evidence of the malignancy at the time of enrollment. Patients with adequately treated squamous cell or basal cell carcinomas of the skin, multiple primary melanomas, or any carcinoma in situ will be allowed.
Corrected QT interval (QTc) greater than 460 ms at baseline
