Active clinical trials for "Carcinoma, Squamous Cell"

This proof-of-concept study aims to assess the clinical and biological effects of Atezolizumab combined with Bevacizumab in advanced previously treated squamous-cell carcinoma of the head and neck (HNSCC).

The purpose of this study is to find out if the addition of nivolumab can improve 2 year progression free survival (PFS) as compared to standard of care of fractionated radiation therapy (RT) and carboplatin/paclitaxel in subjects with high risk HPV-related squamous cell carcinoma of the oropharynx (tonsil, base of tongue, oropharyngeal wall, soft palate). Fractionated means the radiation will be administered in fragments or parts across multiple days.

This is a single-centre feasibility study designed to assess the safety, tolerability and engraftment of MET-4 bacterial strains when given in combination with chemoradiotherapy (CRT). The study will involve a prospective cohort of 30 patients diagnosed with Locoregionally-Advanced Oropharyngeal Squamous Cell Carcinoma (LA-OPSCC) to be treated with CRT as per standard of care at Princess Margaret Cancer Centre. All patients enrolled will receive MET-4 in addition to standard CRT. MET-4 is administered orally as an initial daily loading dose over 2 days followed by a daily maintenance dose of MET-4 and will be administered until week 4 of CRT or unacceptable toxicity whichever occurs earlier and in the absence of criteria to discontinue MET-4. This protocol does not determine eligibility to receive treatment with concurrent CRT. It is anticipated that patient accrual will be completed within 12 months.

This is a Phase 1 first in human, open label, multi-center, dose escalation and dose expansion study to evaluate the safety, tolerability, PK, anti-tumor activity and pharmacodynamic effects of SL-279252 in subjects with advanced solid tumors or lymphomas.

This is an open-label, randomized, phase II trial to test the efficacy of Ibrutinib in combination with either Nivolumab or Cetuximab in the treatment of recurrent and/or metastatic head an neck squamous cell carcinoma

The overarching goal of the MINT trial is to reduce treatment-related toxicity while maintaining efficacy. Patients with HPV-related oropharyngeal squamous cell carcinoma (OPSCC) will undergo resection of the primary tumor site and involved/at risk regional neck nodes.

This randomized phase II trial studies how well transoral surgery followed by low-dose or standard-dose radiation therapy works in treating patients with human papilloma virus (HPV) positive stage III-IVA oropharyngeal cancer. Radiation therapy uses high-energy x-rays to kill tumor cells. Drugs used in chemotherapy work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving radiation therapy with chemotherapy may kill any tumor cells that remain after surgery. It is not yet known how much extra treatment needs to be given after surgery.

No agent is known to have efficacy in patients with incurable HNSCC that progressed with prior platin, 5-FU, cetuximab and taxane. Herein lies the unmet need to be addressed by this trial. Based on the preclinical and clinical data presented, the investigators propose that mitomycin C will have anti-tumor activity in these patients.

The purpose of this research study is to look at the effect of a treatment regimen called CACTUX on head and neck cancer. The CACTUX regimen is a combination of three drugs called cisplatin, nab-paclitaxel, and cetuximab (although carboplatin may be given in place of cisplatin if participants have previously had problems receiving cisplatin). The use of nab-paclitaxel in this combination is different from routine care, in which a drug called 5FU is often given instead, but the investigators group has conducted previous research where the investigators incorporated nab-paclitaxel into routine treatment with cisplatin, 5FU, and cetuximab. The investigators are looking at the incidence of side effects with the CACTUX regimen as well as response of the disease and health status.

Accelerated, normofractionated radiotherapy is the treatment of choice in stage II-III laryngeal and oropharyngeal squamous cell carcinoma (SCC). However, twenty to thirty percent of patients with stage II-III laryngeal and HPV negative oropharyngeal SCC develop disease progression, mainly due to lack of locoregional control. Radiosensitizers such as cisplatin and cetuximab are added to radiotherapy in more advanced stage of head and neck (H&N) cancer. These radiosensitizers improve loco-regional control and overall survival. Unfortunately, as these radiosensitizers, notably cisplatin, also dose intensify the radiation dose in normal tissues, they also significantly increase toxicity. Adding a more tumor-specific radiosensitizing agent could improve loco-regional control and overall survival without significantly increasing toxicity. Radiotherapy kills tumor cells by inducing DNA damage. The efficacy of radiotherapy is limited by the ability of tumor cells to repair this DNA damage. Poly(ADP-ribose)polymerase (PARP) is an essential enzyme in base excision repair and single strand break DNA repair, DNA lesions arising from radiation treatment. PARP inhibition and consequently the inhibition of PARP-facilitated DNA repair enhances the anti-tumor activity of radiotherapy, as shown in preclinical studies including head and neck xenograft studies. This radiosensitization is thought to be proliferation dependent and is more pronounced in homologous recombination (HR) deficient cells, providing an opportunity for tumor specific targeting. Genetic analyses suggest that HR deficiency is commonly found in H&N SCC: ATM loss has been reported in 60% of human H&N SCC biopsies and FANC-F defects were reported in 15-21% of human H&N SCC biopsies and cell lines. The efficacy of radiotherapy is also limited by tumor hypoxia, as tumor hypoxia results in radioresistance. Some PARP inhibiting compounds increase tumor perfusion in xenograft models, thereby reducing hypoxia and specifically sensitizing tumor cells to radiotherapy. Hypoxia is commonly found in H&N SCC and a high pre-treatment hypoxic fraction in H&N SCC tumors is associated with worse outcome. The high prevalence of both hypoxia and HR deficiencies in H&N SCC support the concept of tumor-specific radiosensitization by PARP inhibition in head and neck cancer patients. Olaparib is a potent PARP inhibitor developed as an anti-cancer drug for HR defected tumors and as a dose intensifier for chemo- and radiotherapy. In humans, olaparib has a low toxicity profile as a single agent, with increasing bone marrow toxicity when combined with chemotherapy. The combination of olaparib and radiotherapy for H&N SCC is expected to improve locoregional control and thereby overall survival. However, this combination treatment has never been tested in humans before. The purpose of this study is to determine the safety and tolerability of radiotherapy for stage II-III laryngeal and stage II-III HPV-negative oropharyngeal SCC with concurrent olaparib.
