Thyroid Cancer Squamous Cell Carcinoma Head and Neck Cancer (HNSCC) HRAS Mutant Tumor Other Squamous Cell Carcinoma (SCC) With HRAS Mutant Tumor | Drug: Tipifarnib | Phase 2 |
This Phase II study will investigate the antitumor activity in terms of ORR of tipifarnib in subjects with locally advanced, unresectable or metastatic, relapsed and/or refractory tumors that carry HRAS mutations and for whom there is no curative therapy available. Subjects with information available on tumor HRAS status previously generated are eligible. All subjects must consent to provide at least 10 tumor slides from a prior diagnostic biopsy for a retrospective testing of HRAS gene status at a central facility.
Subjects will be enrolled into three nonrandomized cohorts:
- Cohort 1: Malignant thyroid tumors with HRAS mutations (cohort is closed).
- Cohort 2: Squamous Cell Carcinoma Head and Neck Cancer with HRAS mutations.
- Cohort 3: Squamous Cell Carcinoma (SCC) with HRAS mutations other than HNSCC

- Objective Response Rate (ORR) [ Time Frame: 24 months (approx. 12 months accrual + 12 months follow up) ]
- Progression-free Survival (PFS) [ Time Frame: 24 months (approx. 12 months accrual + 12 months follow up) ]
- Duration of Response (DOR) [ Time Frame: 24 months (approx. 12 months accrual + 12 months follow up) ]
- Number of Subjects with Adverse Events (AEs) and Serious Adverse Events (SAEs) [ Time Frame: Until 30 days after the end of study ]Number of patients that experience Adverse Events (AEs).

Accepts Healthy Volunteers: | No |
Inclusion Criteria:
- histologically or cytologically confirmed diagnosis of thyroid cancer (cohort 1: Note: Cohort closed to further enrolment) or Squamous Cell Carcinoma head and neck cancer (cohort 2) or Squamous Cell Carcinoma other than HNSCC (cohort 3) for which there is no curative therapy available.
- tumor that carries a missense HRAS mutation ith a variant allele frequency (VAF) > 20%.
- Subject consents to provide at least 10 unstained tumor slides for retrospective testing of HRAS gene tumor status
- Subject has measurable disease according to RECIST v1.1 and has relapsed or is refractory to prior therapy.
- At least 2 weeks since the last systemic therapy or radiotherapy regimen prior to enrolment
- ECOG PS 0 or 1
- Acceptable liver function
- Acceptable renal function
- Acceptable hematologic status • Serum albumin ≥ 3.5 g/dL. Subjects with tumors potentially highly sensitive to tipifarnib (HRAS mutant VAF ≥ 35%) may be enrolled despite a serum albumin < 3.5 g/dL.
Exclusion Criteria:
- Prior treatment with an FTase inhibitor
- History of relevant coronary heart disease or myocardial infarction within last 3 years, NYHA Grade III or greater congestive heart failure, cerebro-vascular attack within the prior year, or serious cardiac arrhythmia requiring medication except atrial fibrillation.
- Known uncontrolled brain, leptomeningeal or epidural metastases (unless treated and well controlled for at least 4 weeks prior to Cycle 1 Day 1). Controlled brain metastases that require continuous high dose corticosteroid use within 4 weeks of Day 1.
- Non-tolerable > Grade 2 neuropathy or evidence of unstable neurological symptoms within 4 weeks first dose
- Major surgery, other than diagnostic surgery, within 4 weeks prior to first dose, without complete recovery.
- Active, uncontrolled bacterial, viral, or fungal infections, requiring systemic therapy. Known infection with HIV, or an active infection with hepatitis B or hepatitis C
