Study of Olaparib With Radiation Therapy and Cetuximab in Advanced Head and Neck Cancer With Heavy Smoking History
This is a research study that plans to learn more about the safety and tolerability of an investigational drug called Olaparib, in combination with radiation therapy and cetuximab.
Hypothesis: Intensity modulated radiotherapy with concurrent C225 and Olaparib represents a feasible, biologically-based alternative to standard chemoradiation, with acceptable toxicity, for treatment of locally-advanced HNSCC in patients having a ≥ 10 pack-year smoking history.

Experimental: Olaparib with C225 and Radiation Therapy
Patients will begin taking Olaparib at the assigned dose three days prior to their first Cetuximab infusion. Patients will receive an initial dose of Cetuximab, 400 mg/m², intravenously over 120 minutes on Day 1. The initial dose of C225 will precede the start of radiation by 5-7 days. All patients will receive RT to a total dose of 69.3 Gy in 33 fractions over 6½ weeks. Weekly C225 will be administered at 250 mg/m2 in combination with daily RT. Patients will be assigned to receive Olaparib (25, 50, 100 or 200 mg bid) in combination with RT and C225. Olaparib will be taken twice daily, beginning three days prior to first scheduled C225 infusion. A further dose level of 300mg or 400mg may be considered should the 200mg Olaparib dose be well tolerated in this C225/RT combination schedule.
Olaparib PO (25, 50, 100 or 200 mg bid) in combination with RT and C225. BID, beginning three days prior to first C225 infusion and discontinued after RT completed.
