The goal of this clinical trial is to learn if N17350 works to treat advanced solid tumors in adults. It will also learn about the safety of N17350 and help determine the best dose to use in future studies. The main questions it aims to answer are: 1. Does N17350 cause tumors to shrink or stop growing in some participants with advanced solid tumors? 2. Are there any side effects for participants when taking N17350? 3. What is the safest dose of N17350 and the dose that should be used for further study? 4. Researchers will give N17350 directly into tumor lesions using a needle (intratumoral injection). This is an open-label study, meaning all participants will receive N17350 and there is no placebo. Participants will: 1. Receive injections of N17350 into tumor lesions every second week for 8 or 12 weeks 2. Visit the clinic regularly for checkups, blood tests, and monitoring for side effects 3. Have imaging scans (such as CT or MRI) to measure tumors and assess response 4. Provide blood samples and, when required, tumor samples to help researchers understand how N17350 affects the tumor and the immune system

This is a global, open-label, randomized, 2-arm, Investigator's choice Phase 3 (Pivotal Stage) study to investigate the efficacy and safety of JNJ-90301900 (NBTXR3) / radiation therapy (RT)±cetuximab versus RT±cetuximab in treatment-naïve, platinum-ineligible, elderly participants with locally advanced head and neck squamous cell carcinoma (LA-HNSCC).

This clinical trial proposes to evaluate a relatively unexplored approach to treatment of squamous cell carcinoma (SCC) on the lower extremities. The strategy is to directly and specifically deliver drug to the tumor. For the proposed phase I clinical trial, the investigators will perform intralesional injections of a well characterized, potent chemotherapeutic agent 5-fluorouracil (5FU) with and without a topical application of 0.005% calcipotriene cream to kill topically accessible SCC cells. The goal of the study is to evaluate the safety profile and tolerability of intralesional-5FU with and without a concomitant topical calcipotriene and measure the clinical objective response rate (ORR) in treated lesions compared to untreated lesions 3 weeks after treatment.

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 is to determine whether cervical lymph node dissection is necessarily performed in the presence of early-stage oral squamous cell carcinoma.

The purpose of this study is to gather information on the safety and effectiveness of lenvatinib combined with pembrolizumab in anal/rectal cancer that has spread to other parts of the body and will not respond to standard care.

Circulating tumor DNA (ctDNA) is a blood-based test that measures dying or dead cancer cells that are already circulating in the blood. In this study, the investigators will enroll patients who are planning to receive surgery to remove their head and neck cancer. The investigators are interested to learn how ctDNA levels change with surgery and over the course of time. The investigators also want to determine if there are certain features of the tumor or the patient themselves that might cause ctDNA to be higher than other patients. Also, the investigators want to explore if the detection of ctDNA following surgery is related to cancer recurrence.

This Phase I clinical trial evaluates the safety, tolerability, and optimal dosing of Zanzalintinib in combination with Pembrolizumab and Cetuximab in patients with recurrent and/or metastatic squamous cell carcinoma of the head and neck (R/M HNSCC). The study aims to establish the maximally tolerated dose (MTD) and recommended Phase II dose (RP2D) while also exploring efficacy outcomes, including progression-free survival (PFS) and overall survival (OS).

The investigational drug to be studied in this protocol, BCA101, is a first-in-class compound that targets both EGFR with TGFβ. Based on preclinical data, this bifunctional antibody may exert synergistic activity in patients with EGFR-driven tumors.

As patients live longer after receiving an organ transplant, there is a need to reduce the long-term side effects of the drugs used to prevent organ rejection. In particular, long-term use of these drugs increases the risk of skin cancer. Skin cancer is now a leading cause of illness and disfigurement after kidney, liver, heart, and lung transplantation. Given the increased risk and burden of skin cancer in transplant recipients, prevention is critical. Nicotinamide is a form of Vitamin B3 that has been shown to protect against skin cancer in the general population. However, it is unclear whether nicotinamide is effective among immune-suppressed transplant recipients. Investigators will conduct a clinical trial involving multiple transplant centres in Canada to evaluate whether oral nicotinamide (500 mg twice daily) is effective and safe for preventing skin cancer. Investigators will recruit 396 high-risk adult kidney, liver, heart, and lung transplant patients who have previously had at least one skin cancer. Patients will receive nicotinamide or sham tablets for up to 4 years. The results will inform efforts to improve the long-term health of transplant recipients.

The primary objective of this study is to assess the feasibility of treatment with bintrafusp alfa combined with definitive chemoradiation (carboplatin, paclitaxel and radiation) in patients with squamous cell carcinoma of the esophagus or gastroesophageal junction.

Previous trials, such as ADURA and CTONG, have demonstrated the benefits of neoadjuvant targeted therapy in patient with EGFR mutations , which can effectively reduce the extent of tumors and improve the survival outcomes. However, clinical trials of neoadjuvant targeted therapy in NSCLC have rarely enrolled patients with EGFR-mutated lung squamous cell carcinoma due to its rarity, which means that the safety and feasibility of neoadjuvant osimertinib in patients with resectable stage II-IIIB EGFR-mutated lung squamous cell carcinoma remains controversial.

The purpose of this study is to To confirm the predictive value of CCND1 for TPF induction in cN2 patients with OSCC

This is an Open, Single Arm, Exploratory and Phase II Clinical Trial of Anlotinib Hydrochloride Capsules Combined With TQB2450 Injection in Esophageal Squamous Cell Carcinoma (ESCC) Patients as Postoperative Adjuvant Therapy. In order to observe and evaluate the efficacy and safety of Anlotinib Hydrochloride Capsules combined with TQB2450 Injection in treatment of patients with ESCC. The primary endpoint is disease free survival (DFS).
