Reduction of Postoperative Radiotherapy in Head and Neck Squamous Cell Carcinoma

This is a multi-center study in patients with un-resectable Recurrent or Metastatic HPV16-positive oropharyngeal Head and Neck Squamous Cell Carcinoma (HNSCC). The trial is designed to investigate VB10.16, an investigational therapeutic DNA vaccine in combination with another medicine, pembrolizumab, which is the standard of care for patients with previously untreated metastatic or resectable recurrent PD-L1 positive HNSCC. The study is divided in 2 parts: * Phase 1: Dose escalation to evaluate safety and determine the recommended phase 2 dose (RP2D) of VB10.16 * Phase 2: Randomized comparison of VB10.16 in combination with pembrolizumab versus pembrolizumab monotherapy The goal of Phase 1 is to evaluate the safety and tolerability of the combined treatment and to decide on the dose of VB10.16 to be used in the second part of the trial. The randomized Phase 2 will consist of 2 parallel arms exploring VB10.16 at the selected RP2D from the escalation phase in combination with pembrolizumab SoC (experimental arm, Arm A), versus pembrolizumab alone (control arm, Arm B).

Ficerafusp alfa is directed against two targets, Epidermal Growth Factor Receptor (EGFR) and Transforming Growth Factor beta (TGF-β). This study intends to evaluate the safety and efficacy of ficerafusp alfa in combination with pembrolizumab versus placebo with pembrolizumab in 1L PD-L1-positive, recurrent or metastatic Head and Neck Squamous Cell Carcinoma (HNSCC).

The purpose of this study is to determine safety and preliminary efficacy of amivantamab monotherapy, amivantamab in addition to pembrolizumab, amivantamab in addition to paclitaxel and amivantamab in addition to pembrolizumab and carboplatin in participants with recurrent/metastatic head and neck cancer. The study will also confirm the recommended Phase 2 combination dose (RP2CD) for amivantamab in addition to paclitaxel. The safety and preliminary efficacy of amivantamab in addition to pembrolizumab will also be determined in perioperative (before and after surgery) setting in participants with resectable locally advanced head and neck squamous cell carcinoma (HNSCC).

The purpose of this study is to compare anti-tumor activity of amivantamab in addition to pembrolizumab and carboplatin versus pembrolizumab, 5-fluorouracil (FU), and platinum therapy (carboplatin or cisplatin) in participants with refractory/metastatic (R/M) head and neck squamous cell carcinoma (HNSCC). HNSCC is a type of cancer that develops in the head and neck regions, including the outer tissue layer of the mouth and throat. This study will focus on participants with HNSCC who are treatment-naive (have not received prior treatment) in the R/M setting.
