Neoadjuvant Immunoradiotherapy With Evorpacept and Pembrolizumab in HPVOPC (Human Papilloma Virus Oropharynx Cancer)
February 28, 2024 updated by: Joseph Califano, University of California, San Diego
Neoadjuvant Radiation and Evorpacept (ALX148) in Combination With Pembrolizumab In Patients With Previously Untreated Locally Advanced, Resectable, HPVOPC (Human Papilloma Virus Oropharynx Cancer)
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.
Study Overview
Detailed Description
This is a prospective, multi-center, open-label, one-arm, two-stage, Phase II study to evaluate the efficacy of neoadjuvant immunoradiotherapy (NIRT) in patients with stage I HPVOPC (Human Papilloma Virus Oropharynx Cancer) amenable to surgical resection, including AJCC (American Joint Committee on Cancer) VIII T1-2N1M0 HPVOPC (Human Papilloma Virus Oropharynx Cancer) and excluding patients with solitary lymph nodes less than 3 cm.
A Simon's two-stage optimal design is used for this study.
We will test the hypothesis that neoadjuvant stereotactic tumor targeting radiation along with CD47 inhibition (evorpacept) and PD-1 inhibition (pembrolizumab) provides pathologic response compared to current standard of care rates of locoregional control.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Treatment
Stereotactic radiation therapy (SBRT (8GyX3)) will be delivered to gross tumor volume (GTV) +3mm, followed by Pembrolizumab 200 mg IV and Evorpacept 45 mg/kg IV every three weeks x 2 cycles followed by surgical resection of primary tumor and neck dissection.
|
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)
