Ficerafusp Alfa, Pembrolizumab en Stereotactische Lichaamsradiotherapie (SBRT) bij Hoofd- en Hals Plaveiselcelcarcinoom (HHSCC)

1 november 2026 bijgewerkt door: Washington University School of Medicine

Fase I/II-onderzoek van neoadjuvante combinatie van ficerafusp alfa, pembrolizumab en SBRT voor lokaal gevorderd hoofd-hals plaveiselcelcarcinoom (HNSCC)

The study is an open-label phase I/II clinical trial. The study will enroll patients to receive neoadjuvant SBRT plus 1 or 2 doses of neoadjuvant pembrolizumab with concurrent ficerafusp alfa (4 doses) prior to definitive surgical resection for high-risk, locoregionally advanced HPV-negative head and neck squamous cell carcinoma (HNSCC). Approximately 6 weeks after end of SBRT, patients will undergo standard of care (SOC) surgical resection followed by SOC adjuvant chemoradiation per National Comprehensive Cancer Network (NCCN) guidelines. Adjuvant therapy is not part of this study and therefore is not dictated by study protocol.

Replacement therapy (e.g., thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment.
  • Active systemic infection requiring either hospitalization or parenteral anti-infective therapy within 2 weeks before first dose of study treatment.
  • Chronic hepatitis B virus (HBV) infection with active disease meeting the criteria for anti-HBV therapy but not on a suppressive antiviral therapy prior to initiation of study treatment. HBV testing not required in the absence of known history of infection. Note: Subjects who are hepatitis B surface antigen positive are eligible if they have received HBV antiviral therapy for at least 4 weeks and have undetectable HBV viral load prior to randomization. These subjects should remain on antiviral therapy throughout the study treatment period and follow local guidelines for HBV antiviral therapy post completion of study treatment.
  • Known history of hepatitis C virus (HCV) infection that has not been cured or that has a detectable viral load. Patients with a history of HCV that has been treated and cured are eligible provided they completed curative antiviral therapy at least 4 weeks prior to initiation of study treatment. Patients with HCV infection who are currently on treatment and have an undetectable HCV viral load are eligible. HCV testing not required in the absence of known history of infection.
  • Known history of human immunodeficiency virus (HIV) (HIV 1/2 antibodies) with viral load >0 or CD4<350. HIV testing is not required in the absence of known history of infection.
  • Receipt of any organ transplantation, including autologous and allogeneic stem cell transplantation, except for transplants that do not require immunosuppression.
  • Known to be diagnosed and/or treated for any other additional malignancy within 2 years prior to randomization with the exception of the following: curatively treated basal cell carcinoma or squamous cell carcinoma of the skin, and curatively resected in situ cervical cancer, and curatively resected in situ breast cancer, and low-risk early stage prostate cancer defined as follows: Stage T1c or T2a with a Gleason score ≤ 6 and prostatic-specific antigen < 10 ng/mL either treated with definitive intent or untreated in active surveillance that has been stable for the past year prior to study entry. Other exceptions may be considered with the PI's consultation. The time requirement for no malignancy for 2 years does not apply to the cancer for which a subject is enrolled in the study.
  • Any condition requiring systemic treatment with either corticosteroids (>10 mg daily of prednisone or equivalent) or other immunosuppressive medication within 7 days prior to the first dose of study treatment, except for topical, intranasal, intrabronchial, or ocular steroids. Corticosteroid use as premedication for allergic reactions (e.g., intravenous contrast), or as a prophylactic management of AEs related to the therapies specified in the protocol is allowed. The use of physiologic doses of corticosteroids may be approved after consultation with the principle-Investigator.
  • Use of a live or live attenuated vaccine within 4 weeks prior to Screening. Note: Administration of killed, recombinant, or inactivated vaccines is allowed.

Primaire uitkomstmaten

Uitkomstmaat
Maatregel Beschrijving
Tijdsspanne
Phase I only: Maximum tolerated dose (MTD) of SBRT in combination with pembrolizumab plus ficerafusp alfa
Tijdsspanne: From start of treatment until date of surgery (total estimated time of 7 weeks)

The maximum tolerated dose (MTD) is defined as the highest dose level at which 0 or 1 patients of a cohort experience dose-limiting toxicity during the dose limiting toxicity (DLT) window. DLTs are defined in the protocol.
From start of treatment until date of surgery (total estimated time of 7 weeks)
Phase II only: Rate of pathologic complete response (pCR)
Tijdsspanne: At the time of surgery (estimated to be week 7)

Response will be defined according to the systematic pTR system. pTR is defined as the presence of tumor cell necrosis and keratinous debris with giant cell/histiocytic reaction, quantified as a percentage of the overall tumor bed (area pathologic response/area pathologic response plus viable tumor). pCR is defined as follows: 100% of sample characterized by tumor necrosis, keratinous debris, and/or giant cells/histiocytes
At the time of surgery (estimated to be week 7)

Secundaire uitkomstmaten

Uitkomstmaat
