Oropharynx Squamous Cell Carcinoma

This Phase 3, multicenter, randomized, open-label study evaluates APG-157 in adults with newly diagnosed locally advanced head and neck squamous cell carcinoma (LA-HNSCC). Two independently powered cohorts are enrolled based on treatment pathway. Cohort A evaluates APG-157 administered as neoadjuvant therapy before curative-intent surgery in participants with resectable oral cavity or oropharyngeal cancer who are medically ineligible for perioperative pembrolizumab. Cohort B evaluates APG-157 administered as induction therapy before definitive chemoradiotherapy and as maintenance therapy after chemoradiotherapy in participants with unresectable or medically inoperable disease. Participants are randomized 1:1 within each cohort to receive APG-157-based treatment or standard-of-care therapy. The primary hypothesis is that APG-157 given before definitive surgery followed by (chemo)radiotherapy improves event-free survival (EFS) compared to surgery and adjuvant (chemo)radiotherapy alone (Cohort A), and that APG-157 given as induction therapy prior to definitive chemoradiotherapy (CRT) followed by maintenance APG-157 improves EFS compared to definitive CRT alone (Cohort B).

The primary goal of this study is to examine whether recurrence of HPV-associated OPSCC can be predicted by two factors: 1) mutations in genes called TRAF3 and CYLD, and 2) measurements of circulating HPV DNA in blood plasma. The study will also investigate whether HPV integration is associated with TRAF3 and CYLD mutations, and whether recurrence prediction improves when looking at HPV integration along with TRAF3 and CYLD mutations.

The purpose of this study to find out whether sacituzumab govitecan in combination with cetuximab is an effective and safe treatment approach for people with recurrent and/or metastatic head and neck squamous cell cancer (HNSCC).

Patients with human papillomavirus (HPV)-related oropharyngeal cancer generally have favorable outcomes and how well they do depends on the specific details about the patient and their cancer. How well they do isn't as related to the kinds of treatment they get. However, there are significant side effects for the various types of treatments they may get. Because these patients generally have favorable outcomes no matter the kind of treatment, reducing side effects should be a priority when choosing their treatment. The goal of this clinical research study is to evaluate whether a new blood test called a Circulating Tumor DNA test (ctDNA test) can decrease the number of people that require radiation after surgery. This blood test is often elevated in people when they are diagnosed with head and neck cancer. There are studies that show that cancer most often returns when this blood test is positive after treatment. This study will test patients' blood before and after surgery. In cases where the test is negative after surgery, people on the study will not receive radiation unless they are considered high risk based on surgery findings. The hope is that radiation and its potential side effects can be limited to only people that need the treatment.

SURVEILLE-HPV - A new post therapeutic surveillance strategy for HPV-driven oropharyngeal cancer based on HPV Circulating DNA measures. HPV-positive oropharyngeal cancer patients have a much better prognosis that their HPV-negative counterparts. Despite this, Post Treatment Surveillance (PTS) strategy does not take into account HPV status. HPV Circulating DNA (HPV Ct DNA) has emerged as a promising tool to assess the risk of cancer recurrence following treatment. We assume that this biomarker could be helpful to guide PTS. The number of systematic PTS visits could be significantly reduced in patients with undetectable HPV Ct DNA whereas a closer clinical and radiological follow up could be performed in case of detectable HPV Ct DNA. If confirmed, this new strategy could have several benefits including: * reduction of PTS visits for most HPV-positive patients which implies a potential cost decrease and * Identification of relapse at early stages (before the occurrence of symptoms)

To evaluate the design, safety and efficacy of OralViome Cancer Testing system in the early detection of Oral and Throat Cancers using saliva metatranscriptomic analysis. This study will recruit only at existing clinical sites and will NOT use any additional clinical sites.

The goal of this clinical trial is to determine the value of circulating tumour HPV DNA (human papilloma virus DNA found in the blood) at diagnosis, during treatment, and in the follow-up of patients diagnosed and treated for throat cancer caused by HPV. The main question to answer is if the presence of HPV DNA in the blood one month after the treatment is useful in detecting remaining tumour or relapse within two years after treatment. The participants will be asked to provide blood tests: 1. before treatment 2. weekly during the treatment 3. on all scheduled follow-up appointments 4. on all unplanned appointments where a relapse is suspected
