Trial Summary

What is the purpose of this trial?

This trial is testing a new treatment that helps the immune system fight cancer while also using drugs to kill cancer cells.

Do I have to stop taking my current medications for this trial?

The trial protocol does not specify if you need to stop taking your current medications. However, if you are on corticosteroids or other immunosuppressive treatments, you may not be eligible to participate.

What data supports the idea that Cemiplimab + Chemotherapy for Head and Neck Cancer is an effective treatment?

The available research shows that a combination of paclitaxel and carboplatin, which are part of the Cemiplimab + Chemotherapy treatment, was effective in heavily pretreated patients with head and neck cancer. In a study, 39% of patients showed a positive response, with some achieving complete or partial recovery. This suggests that the treatment can be effective, especially for those who have already undergone other treatments. Additionally, combined approaches like chemotherapy and radiotherapy have shown better results than radiotherapy alone, indicating that using multiple methods together can improve outcomes. ^{1 2 3 4 5}

What safety data is available for Cemiplimab and Chemotherapy in head and neck cancer treatment?

The safety data for similar treatments involving carboplatin and paclitaxel, often used in combination with immunotherapy agents like pembrolizumab, indicate that these combinations are generally well-tolerated. In a study with pembrolizumab, carboplatin, and paclitaxel, 100% of patients experienced Grade 1-2 adverse events, and 30% experienced Grade 3 adverse events such as anemia, neutropenia, thrombopenia, and hypertension. Another study with paclitaxel and carboplatin reported tolerable toxicity, with some patients experiencing Grade II and III neutropenia and neurotoxicity. These findings suggest that while adverse events are common, they are often manageable, and the treatment is considered effective in heavily pretreated patients with head and neck cancer. ^{1 4 6 7 8}

Is the drug combination of Carboplatin, Cemiplimab, and Paclitaxel promising for head and neck cancer?

Yes, the combination of Carboplatin, Cemiplimab, and Paclitaxel is promising for head and neck cancer because similar combinations have shown high response rates and effectiveness in treating this type of cancer. ^{3 5 9 10 11}

Treatment Details

Interventions

• Carboplatin (Alkylating agents)
• Cemiplimab (Monoclonal Antibodies)
• Paclitaxel (Alkylating agents)

Trial Overview The trial is testing cemiplimab (an immune system-boosting monoclonal antibody) combined with low-dose paclitaxel and carboplatin (chemotherapy drugs). The goal is to see if this combination is more effective in stopping cancer growth compared to other treatments for head and neck cancers that have spread or returned after treatment.

Participant Groups

Group I: Treatment (cemiplimab, paclitaxel, carboplatin) Experimental Treatment 3 Interventions

Patients will be treated with a combination of cemiplimab 350 mg every three weeks, with weekly combination of paclitaxel 25 mg/m2 and carboplatin AUC 1. Treatment will continue for a total of 24 months or until disease progression or unacceptable toxicity. Weekly chemotherapy will stop after six months of treatment (24 weeks). A ten patient safety run-in phase will be initially performed.

Carboplatin is already approved in Canada for the following indications:

Approved in Canada as Carboplatin for:

• Ovarian cancer
• Small cell lung cancer
• Testicular cancer

Findings from Research

In a study of 59 patients with recurrent or metastatic head and neck cancer treated with weekly cetuximab and paclitaxel, the median progression-free survival was 5.7 months and the median overall survival was 11.8 months, indicating a potential benefit of this treatment regimen.

Patients who had previously received cetuximab experienced shorter progression-free and overall survival, suggesting that prior treatment may negatively impact the effectiveness of the Cmab-PTX combination.

In a phase II study involving 24 heavily pretreated patients with advanced head and neck cancer, the combination of paclitaxel and carboplatin resulted in an overall response rate of 39%, with 17% achieving a complete response and 22% a partial response.

The treatment was generally tolerable, although 79% of patients experienced neurotoxicity, and some had significant neutropenia, indicating that while effective, careful monitoring of side effects is necessary.

In a study of 46 patients with recurrent or metastatic squamous cell carcinoma of the head and neck, the combination of weekly paclitaxel and cetuximab showed a promising overall response rate of 54%, with 22% achieving complete responses.

The treatment was well tolerated, with a disease control rate of 80% and median overall survival of 8.1 months, making it a potential option for patients who cannot receive platinum-based therapies.

Phase II study of the combination of cetuximab and weekly paclitaxel in the first-line treatment of patients with recurrent and/or metastatic squamous cell carcinoma of head and neck. Hitt, R., Irigoyen, A., Cortes-Funes, H., et al.[2022]

In a study of 160 patients with advanced oropharyngeal squamous cell carcinoma treated with carboplatin, paclitaxel, and radiation over 10 years, the overall survival rates were 81.7% at 3 years and 70.7% at 5 years, indicating effective treatment outcomes.

The treatment demonstrated an acceptable side effect profile, with the most common adverse effect being acute dysphagia (75.25%), and only 11.9% of patients experiencing significant hematologic toxicities, suggesting carboplatin may be a safer alternative to cisplatin.

In a case series of patients with recurrent/metastatic head and neck squamous cell carcinoma (R/M HNSCC), a combination treatment of paclitaxel, carboplatin, cetuximab, and pembrolizumab resulted in significant clinical responses, with all patients achieving an objective response (6 complete responses and 2 partial responses).

The treatment was generally safe, with manageable adverse events, although one patient experienced liver toxicity related to the immune checkpoint inhibitor. This suggests that the quadruple therapy could be a promising option for R/M HNSCC, warranting further clinical trials.

High Response Rate to Carboplatin-Paclitaxel-Cetuximab and Pembrolizumab in Patients with Recurrent and/or Metastatic Head and Neck Squamous Cell Carcinoma. Chauffert, B., Zhou, Y., Medjkoune, L., et al.[2023]

Cytotoxic chemotherapy for recurrent and/or metastatic head and neck squamous cell cancer (R/M HNSCC) primarily includes platinum agents, taxanes, and antimetabolic agents, which are commonly used to manage the disease.

Cetuximab, a monoclonal antibody targeting the epidermal growth factor receptor, shows modest effectiveness in treating R/M HNSCC, highlighting the importance of a multidisciplinary approach in palliative care planning.
