Registration Number
NCT04997902
Lead Sponsor
Kura Oncology, Inc.
Brief Summary

This phase 1/2 combination trial of tipifarnib, a farnesyltransferase inhibitor, and alpelisib, a PI3K inhibitor in participants with recurrent/metastatic head and neck squamous cell carcinoma (HNSCC) whose tumors overexpress the HRAS protein and/or are PIK3CA-mutated and/or PIK3CA-amplified.

  8. Must be able to swallow alpelisib whole tablet or oral suspension containing crushed tablets. Feeding tube may not be used for alpelisib administration.
  9. Other protocol defined inclusion criteria may apply.
Exclusion Criteria

  4. Received treatment for unstable angina, myocardial infarction, and/or cerebro-vascular attack within the prior 6 months.
  5. Non-tolerable Grade 2, or ≥ Grade 3 neuropathy or evidence of unstable neurological symptoms within 4 weeks of Cycle 1 Day 1.
  6. Major surgery, other than diagnostic surgery, within 2 weeks prior to Cycle 1 Day 1, without complete recovery.
  7. Active, uncontrolled bacterial, viral, or fungal infections requiring systemic therapy.
  8. Participant with an established diagnosis of diabetes mellitus Type 1 or not controlled Type 2.
  9. Participant has impairment of gastrointestinal (GI) function or GI disease that may significantly alter the absorption of the trial drugs based on Investigator discretion.
  10. Participant has currently documented pneumonitis/interstitial lung disease.
  11. Participant has a history of severe cutaneous reaction, such as Stevens-Johnson Syndrome (SJS), Erythema Multiforme (EM), Toxic Epidermal Necrolysis (TEN), or Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS).
  12. Other protocol defined exclusion criteria may apply.
