What You Need to Know Before You Apply

What is the purpose of this trial?

This trial is testing two new drugs, HB-201 and HB-202, which aim to help the immune system fight HPV 16-related cancers. It focuses on patients with advanced head and neck cancer who are also receiving a standard treatment called pembrolizumab. The goal is to see if these new drugs can improve the body's ability to combat cancer.

Will I have to stop taking my current medications?

The trial protocol does not specify if you must stop taking your current medications, but it mentions that you must meet certain 'washout periods' (time without taking certain medications) for prohibited medications. It's best to discuss your current medications with the trial team to see if any adjustments are needed.

What safety information is available for pembrolizumab in head and neck cancer treatment?

Pembrolizumab, used for head and neck cancer, can cause side effects like diarrhea, skin rash, and thyroid issues, with rare severe lung inflammation. It's important to monitor and manage these side effects early. ^{1 2 3 4 5}

What makes the Viral Therapy + Pembrolizumab treatment unique for head and neck cancer?

The Viral Therapy + Pembrolizumab treatment is unique because it combines a viral therapy (HB-201, HB-202) with pembrolizumab, an immune checkpoint inhibitor, potentially enhancing the immune system's ability to target cancer cells in head and neck cancer, which is different from standard treatments that typically involve pembrolizumab alone or with chemotherapy. ^{3 6 7 8 9}

What data supports the effectiveness of the drug pembrolizumab for head and neck cancer?

Pembrolizumab has been shown to be effective for treating recurrent or metastatic head and neck squamous cell carcinoma, with studies indicating it can improve survival and response rates, especially when used as a first-line treatment or in combination with chemotherapy. ^{3 7 10 11 12}

Published Research Related to This Trial

In a study with 882 patients over a median follow-up of 45 months, pembrolizumab and pembrolizumab-chemotherapy showed significant improvements in overall survival compared to cetuximab-chemotherapy for recurrent/metastatic head and neck squamous cell carcinoma, particularly in patients with high PD-L1 expression (CPS ≥ 20).

The analysis also indicated that patients who received pembrolizumab-based therapies had favorable outcomes in subsequent treatments, with improved progression-free survival on next-line therapies, highlighting the long-term efficacy of pembrolizumab in this patient population.

Immune checkpoint inhibitors, like nivolumab and pembrolizumab, have become the standard treatment for recurrent or metastatic head and neck squamous cell carcinoma that cannot be treated with surgery or radiotherapy.

Nivolumab is approved for use regardless of PD-L1 expression in patients who have progressed after platinum therapy, while pembrolizumab requires specific conditions related to PD-L1 expression and prior treatment response.

A 69-year-old patient with relapsed squamous cell carcinoma showed significant improvement after 14 cycles of pembrolizumab, indicating its efficacy as a second-line treatment for metastatic head and neck cancer.

The patient developed severe immune-related adverse effects, specifically grade 4 mucositis and esophagitis, highlighting the importance of monitoring for such complications in patients receiving PD-1 inhibitors like pembrolizumab.

In a study of 646 adults with recurrent or metastatic head and neck squamous cell carcinoma (R/M HNSCC), real-world outcomes showed that pembrolizumab, whether used alone or with chemotherapy, provided similar overall survival rates to those seen in clinical trials, with median overall survival of 12.1 months for monotherapy and 11.9 months for combination therapy.

Factors such as HPV-positive tumor status and lower Eastern Cooperative Oncology Group performance status were associated with longer overall survival, highlighting the importance of tumor characteristics in treatment outcomes.

Pembrolizumab has been approved by the FDA as the first-line treatment for both HPV-positive and HPV-negative recurrent head and neck squamous cell carcinoma, marking it as a significant advancement in immunotherapy for this cancer type.

The approval allows pembrolizumab to be used either alone for tumors expressing PD-L1 or in combination with chemotherapy, highlighting the need for healthcare providers to be aware of and manage potential immune-related toxicities such as dermatitis and mucositis associated with this treatment.

Pembrolizumab, a PD-1 inhibitor, has shown significant overall response rates and survival benefits in patients with recurrent or metastatic head and neck squamous cell carcinoma compared to chemotherapy alone, particularly in populations with high PD-L1 expression (CPS ≥ 20 and CPS ≥ 1).

The safety profile of pembrolizumab is comparable to other PD-1/PD-L1 inhibitors, with common side effects including diarrhea and hypothyroidism, but it has a favorable toxicity profile compared to the EXTREME chemotherapy regimen, highlighting the importance of PD-L1 scoring for patient selection.

In a study of 36 patients with resectable HPV-unrelated head and neck squamous-cell carcinoma, neoadjuvant pembrolizumab was found to be safe, with no serious adverse events reported during treatment.

The treatment resulted in a pathologic tumor response in 44% of patients, and the one-year relapse rate for those with high-risk pathology was significantly lower at 16.7%, compared to the historical rate of 35%.

In a study of adult patients with metastatic head and neck squamous cell cancer, substituting 5-fluorouracil (5-FU) with a taxane in a pembrolizumab-based treatment regimen did not increase toxicity or worsen survival outcomes.

Patients receiving the taxane combination experienced significantly lower rates of mucositis and elevated creatinine levels compared to those on the 5-FU regimen, indicating a better safety profile for the taxane approach.

In a phase IB study involving 59 patients with locally advanced head and neck squamous cell carcinoma, the combination of pembrolizumab with cisplatin-based chemoradiotherapy was found to be safe, with a high completion rate of treatment and only 8.8% of patients experiencing immune-related adverse events.

The treatment showed promising efficacy, with complete response rates of 85.3% for HPV-positive and 78.3% for HPV-negative patients, suggesting that this combination warrants further investigation.

In a study of 139 patients with recurrent and metastatic head and neck squamous cell carcinoma, pembrolizumab monotherapy showed similar long-term survival rates compared to combination therapy with chemotherapy, with 2-year progression-free survival at 28.6% and overall survival at 41.8%.

Patients receiving pembrolizumab monotherapy who experienced adverse events had a better prognosis than those without adverse events, suggesting that monotherapy may be a safer and more effective long-term treatment option compared to combination therapy, which did not improve prognosis and could lead to more side effects.

In a study of 34 patients with recurrent and/or metastatic head and neck squamous cell carcinoma treated with PD-1 inhibitors, 29% experienced hyperprogression, where tumor growth accelerated during treatment.

Hyperprogression was significantly associated with regional recurrence, leading to shorter progression-free survival, but did not affect overall survival, highlighting the need for further research into the mechanisms behind this phenomenon.
