PROGRESS Trial - Prophylactic Gabapentin for Relief of Symptoms and Improved Swallowing

A Phase II Randomized Trial of Prophylactic Gabapentin Plus Best Supportive Care Versus Best Supportive Care Alone for Patients Receiving Induction Chemotherapy Followed by Response-Stratified Locoregional Therapy for Locoregionally-Advanced, HPV-Related Oropharyngeal Cancer: An Optima II Secondary Study

Enrollment is only available to patients enrolled on the Optima II study (NCT03107182).

The purpose of this trial is to compare rates of opioid use at completion of radiation for patients with Common Terminology Criteria for Adverse Events (CTCAE) grade ≥ 2 oral mucositis after receiving definitive nonoperative locoregional therapy with or without prophylactic gabapentin as part of best supportive care for locoregionally-advanced, HPV-related oropharyngeal cancer. Secondary purposes include comparison of total equivalent opioid dosage above baseline opioid use at end of treatment, quality of life metrics, swallowing function, feeding tube dependence, and protocol compliance in patients managed with best support care with or without prophylactic gabapentin. Rates of gabapentin-related side effects and discontinuation will also be investigated.

Enrollment is only available to patients enrolled on the Optima II study (NCT03107182).

Primary objective: To compare rates of opioid requirement as a function of supportive care in patients experiencing CTCAE grade ≥2 oral mucositis at completion of radiation or chemoradiation as part of OPTIMA II

Secondary objectives: To compare total opioid equivalent dose above baseline opioid requirement at end of radiation, quality of life metrics, swallowing function, feeding-tube dependence, and protocol compliance in patients managed with best supportive care with or without prophylactic gabapentin. To investigate rates of gabapentin-related toxicity and discontinuation for patients treated on protocol.
