No results posted yet for this study

Summary

The majority of head and neck cancer patients do not respond to immunotherapies, and clinical responses are often not durable. However, targeting tumors with stereotactic radiation in combination with immunotherapy while sparing draining lymphatics enhances anticancer immunity, resulting in dramatic response in HPV (Human Papilloma Virus) virus related cancers of the throat. This trial will leverage targeted tumor radiation and immunotherapy in advance of standard surgical therapy to improve the response of HPV (Human Papilloma Virus) throat cancer to radiation and immunotherapy.

Conditions

  • Oropharynx Cancer

Interventions

DRUG

Evorpacept

After stereotactic radiation to primary tumor and neck on week 1 of study, Evorpacept 45 mg/kg is administered by IV infusion every three weeks starting on Week 2, Day 1 of study for a total two 21-day cycles (6 weeks)
