Status and phase: Completed; Phase 2

Conditions: HNSCC; HRAS Gene Mutation

Treatments: Device: HRAS Detection Assay; Drug: Tipifarnib

Study type: Interventional

KO-TIP-007

Details and patient eligibility

About

An international, multicenter, open-label, 2 cohort, non-comparative, pivotal study evaluating the efficacy of tipifarnib in HRAS mutant HNSCC (AIM-HN). The first cohort will assess the objective response rate (ORR) of tipifarnib in subjects with HNSCC with HRAS mutations. The second study cohort, SEQ-HN, is an observational sub-study including HNSCC patients in whom HRAS mutations were not identified (wild type HRAS HNSCC) and who consent to provide first line outcome data and additional follow up.

Full description

KO-TIP-007 is an international, multicenter, open-label, 2 cohort, non-comparative, pivotal study evaluating the efficacy of tipifarnib in HRAS mutant HNSCC (AIM-HN) and the impact of HRAS mutations on response to first line systemic therapies for HNSCC (SEQ-HN). KO-TIP-007 has 2 study cohorts. The first study cohort, named AIM-HN, includes HNSCC subjects with HRAS mutations. AIM-HN subjects will receive treatment with tipifarnib and the outcome of this cohort will be evaluated for ORR by an independent review facility.

The second study cohort, SEQ-HN, is an observational sub-study including HNSCC patients in whom HRAS mutations were not identified (wild type HRAS HNSCC) and who consent to provide first line outcome data and additional follow up.

HNSCC patients in whom HRAS mutations are identified and who meet eligibility criteria will be offered participation in AIM-HN. HNSCC patients in whom HRAS mutations are not identified may participate in SEQ-HN only. These patients will be followed and the comparison of outcomes of HRAS mutant and HRAS wild type HNSCC will address the exploratory objective to determine the effect of HRAS mutation on the ORR of first line systemic therapy in patients with recurrent/metastatic HNSCC. Outcome data from subsequent lines of therapy will be collected.
