What You Need to Know Before You Apply

What is the purpose of this trial?

This trial examines treatments for oral cancer to determine if immunotherapy with radiation is more effective than the standard chemoradiotherapy. The usual treatment combines chemotherapy with cisplatin and radiation. This trial tests whether adding immunotherapy drugs like durvalumab could help prevent cancer recurrence. It targets individuals with HPV-related oral cancer who have an intermediate risk and whose cancer has not spread beyond the local area. Participants must have a history of smoking and be able to manage daily activities well. As a Phase 2 trial, this research measures the treatment's effectiveness in an initial, smaller group, allowing participants to contribute to advancing cancer treatment.

Will I have to stop taking my current medications?

The trial protocol does not specify whether you need to stop taking your current medications. However, it mentions that you should not be on any other anti-cancer therapy or participate in other clinical studies during the trial. It's best to discuss your current medications with the trial team to ensure they don't interfere with the study treatments.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

In a previous study, patients taking durvalumab alone or with tremelimumab experienced manageable side effects. For example, a trial with 267 participants found these treatments were generally well-tolerated. Another study noted that a small number of patients using durvalumab and tremelimumab together experienced immune-related lung issues, such as pneumonitis.

Cisplatin, the chemotherapy drug used with radiation, serves as a standard treatment for various cancers. It can cause side effects like nausea and kidney problems, but doctors usually manage these effectively. Its common use indicates it is considered safe enough for treatment.

Overall, these studies suggest both new and existing treatments are generally well-tolerated, though side effects can occur. Participants should discuss potential risks with their healthcare providers. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about these treatments for oral cancer because they offer innovative approaches compared to the standard chemoradiotherapy. Most treatments for this condition typically involve cisplatin with radiation, which can be taxing on the body. However, the study's treatment options include the use of durvalumab, an immunotherapy drug that helps the immune system target cancer cells more effectively, both with and without the addition of another immunotherapy agent, tremelimumab. These treatments leverage the body's immune response, potentially reducing some of the severe side effects associated with traditional chemotherapy, and opening new avenues for more personalized cancer care.

What evidence suggests that this trial's treatments could be effective for oral cancer?

This trial will compare chemoradiotherapy with immunotherapy combined with radiation for oral cancer. Research has shown that durvalumab, one of the treatments in this trial, shows promise in treating head and neck cancers when used with radiation. Studies have found that adding tremelimumab to durvalumab, another treatment arm in this trial, can enhance its effectiveness by potentially boosting the immune system's ability to fight cancer. Although some studies did not fully achieve their main goals, patients still experienced noticeable benefits. Durvalumab, alone or with tremelimumab, has been effective for patients with certain cancers, such as those linked to human papillomavirus (HPV). Overall, these treatments offer new hope for reducing cancer recurrence in patients with oral cancer. ^{6 7 8 9 10}

Published Research Related to This Trial

In a safety run-in phase of the DURIGAST PRODIGE 59 study involving 11 patients with advanced gastric or gastro-oesophageal junction adenocarcinoma, 63.6% experienced significant adverse events, primarily neutropenia, indicating a notable safety concern with the treatment combination.

The combination of FOLFIRI with Durvalumab and/or Tremelimumab showed an expected safety profile, allowing progression to the randomized phase II study, although careful monitoring for serious adverse events is necessary.

Durvalumab, a PD-L1 inhibitor, has been shown to be safe for patients with various solid tumors, with common side effects including pruritus and fatigue, based on a meta-analysis of 17 studies involving 1,529 patients.

Higher levels of PD-L1 expression in tumors are linked to better treatment responses to durvalumab, indicating that PD-L1 could serve as a useful biomarker for predicting the drug's efficacy.

In a phase 3 study of 713 patients with stage III non-small-cell lung cancer, durvalumab significantly improved progression-free survival compared to placebo, with a median of 16.8 months versus 5.6 months, respectively.

Durvalumab also showed a higher response rate (28.4% vs. 16.0%) and longer median time to death or distant metastasis (23.2 months vs. 14.6 months), while safety profiles were similar between durvalumab and placebo groups.

In a trial involving 20 patients with recurrent/metastatic oral squamous cell carcinoma, the combination of camrelizumab with docetaxel and cisplatin showed a median overall survival of 14.4 months and an overall response rate of 40%, indicating promising efficacy.

The treatment was generally well tolerated, with 45% of patients experiencing grade ≥ 3 treatment-related adverse events, the most common being anemia and stomatitis, but no treatment-related deaths occurred.

In a phase 2 trial involving 90 patients with non-small-cell lung cancer resistant to PD-1/PD-L1 therapy, the combination of PD-L1 (durvalumab) and CTLA-4 (tremelimumab) with radiotherapy did not show improved overall response rates compared to the therapy alone, leading to the trial's early termination due to futility.

The most common serious adverse events were manageable, but one patient in the low-dose radiotherapy group died from respiratory failure potentially related to the treatment, highlighting the need for careful monitoring in future studies.

In a study of 107 patients with stage III non-small cell lung cancer (NSCLC) treated with concurrent chemoradiotherapy (CCRT) and intensity-modulated radiotherapy (IMRT), the median progression-free survival (PFS) was 20.7 months, indicating effective treatment outcomes.

Factors associated with longer PFS included a favorable response to CCRT, a radiation dose of 62 Gy or more, and having stage IIIA NSCLC, while shorter durations of durvalumab treatment and lower radiation doses were linked to increased mortality risk.

In a phase II study involving 29 patients with locally advanced head and neck squamous cell carcinoma who were ineligible for cisplatin, the combination of pembrolizumab and radiotherapy showed promising efficacy, with a 24-month progression-free survival rate of 71%.

The treatment was generally well-tolerated, although a significant number of patients experienced grade 3/4 lymphopenia (58.6%), indicating the need for monitoring immune cell changes during therapy.

In a study involving 10 patients receiving palliative radiotherapy (RT) combined with durvalumab, the treatment was well tolerated, with only 50% experiencing mild to moderate adverse events, primarily G2 mucositis, and no severe adverse events reported.

The treatment showed promising efficacy, with a 60% objective response rate in evaluable lesions and a significant decrease in tumor growth rate after RT, indicating that durvalumab combined with RT may effectively reduce tumor size in this patient population.
