Combination Trial of Tipifarnib and Alpelisib in Adult Recurrent/ Metastatic Head and Neck Squamous Cell Carcinoma (R/M HNSCC)

Kura Oncology, Inc.45 enrolled

Overview

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.

Eastern Cooperative Oncology Group (ECOG) performance status of 0-1. 7. Acceptable liver, renal, endocrine, and hematologic function. 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: 1. Histologically confirmed salivary gland, thyroid, (primary) cutaneous squamous or nonsquamous histologies (eg, mucosal melanoma). 2. Ongoing treatment with certain anticancer agents. 3. Prior treatment (at least 1 full treatment cycle) with an FTI or PI3K, mTOR, or AKT inhibitor. 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.

Outcomes

Primary Outcomes

Dose-limiting toxicity (DLT)

Rate of DLTs per dose level

Time frame: First 28 days (1 cycle) of combination therapy

Descriptive statistics of Adverse Events (AEs)

Descriptive statistics of Treatment-Emergent Adverse Events (TEAEs) and Serious TEAEs; AE severity will be assessed per the NCI CTCAE v 5.0

Time frame: From Cycle 1 Day 1 until 30 days after last trial intervention dose or 30 days after trial completion, whichever comes first, assessed up to 2 years

Secondary Outcomes

Objective Response Rate (ORR)

Overall confirmed response rate (Complete Response or Partial Response)

Time frame: From Cycle 1 Day 1 until first documentation of disease progression, the start of new anti-cancer therapy, or death, whichever occurs first, assessed up to 2 years

Median duration of response

Defined for participants with confirmed objective response as the time from the first documentation of response to the first documentation of disease progression by RECIST v1.1 or to death due to any cause before new anti-cancer treatment, whichever occurs first

Time frame: From first documentation of response to first documentation of disease progression, the start of new anti-cancer therapy, or death, whichever occurs first, assessed up to 2 years

Disease control rate (DCR)

Disease control rate (CR + PR + SD)

Time frame: From Cycle 1 Day 1 until first documentation of disease progression, the start of new anti-cancer therapy, or death, whichever occurs first, assessed up to 2 years

Median duration of Disease Control

Defined for participants with confirmed objective response as the time in months from the first documentation of response to the first documentation of disease progression by RECIST v1.1 or to death due to any cause before new anti-cancer treatment, whichever occurs first, in patients with confirmed CR/PR
