QUADSHOT: "QUAD SHOT" Radiotherapy With Pembrolizumab in Patients With Recurrent Head & Neck Cancer
Study Details
Study Description
Brief Summary
The purpose of this study is to test the safety of palliative "QUAD SHOT" radiotherapy combined with pembrolizumab and evaluate the effects of the combination treatment patients with recurrent cancer of head and neck.
| Condition or Disease | Intervention/Treatment | Phase |

Phase 2 |
Detailed Description
During this study, patients will receive infusions of pembrolizumab with radiotherapy (palliative QUADSHOT regimen). The patient will receive treatment of pembrolizumab once every 3 weeks and palliative "QUAD SHOT" radiotherapy every 4 weeks. These 28 day period of time is called a cycle. The cycle will be repeated 3 times. Each cycle is numbered in order. The patient will be treated for up to 3 cycles followed by pembrolizumab single drug until unacceptable toxicity or tumor progression.
The patient will also complete a survey.
Total duration of the study is up to two years.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Pembrolizumab + QUADSHOT Radiotherapy Combination Treatment Pembrolizumab by IV once on day 1 of 21 day cycle, begin 7 days before the first round of QUAD SHOT radiotherapy. QUAD SHOT radiotherapy twice a day for two days, begin 7 days after the first dose of pembrolizumab; repeat every 28 days for up to 3 rounds. Maintenance Treatment Pembrolizumab by IV once on day 1 of 21 day cycle On day 21, if the medical oncologist feels that the patient may safely continue treatment, patient will receive a new 21 days cycle of treatment with pebrolizumab. |
Drug: Pebrolizumab + QUADSHOT Radiotherapy
Treatment will consist of "QUAD SHOT" radiotherapy combined with pembrolizumab.
