What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests whether combining the immunotherapy drugs durvalumab (Imfinzi) and tremelimumab with varying doses of radiation therapy can more effectively treat colorectal and non-small cell lung cancer that has metastasized. The researchers aim to evaluate the efficacy of these combined treatments and understand their side effects. Suitable participants have colorectal or non-small cell lung cancer that has progressed after prior treatments. As a Phase 2 trial, the research focuses on assessing the treatment's effectiveness in an initial, smaller group of participants.

Will I have to stop taking my current medications?

The trial requires that at least 21 days have passed since your last systemic therapy (like chemotherapy or radiation) before starting the study treatment. If you are currently on any investigational agents or immunosuppressive medications, you will need to stop those before participating.

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

Research has shown that durvalumab and tremelimumab have been tested for safety both alone and with radiation therapy. In previous studies, a notable side effect was a lung condition called immune-mediated pneumonitis, occurring in about 1.3% of patients. Although some cases were serious, they were rare.

When used together without radiation, durvalumab and tremelimumab caused immune-mediated colitis (inflammation of the colon) or diarrhea in about 6% of patients, with some cases being serious.

Researchers are now combining these treatments with radiation to assess their combined effectiveness. While some risks exist, they are uncommon. Discuss any concerns or questions about these treatments with a healthcare provider. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about these treatments because they combine immunotherapy with radiation to enhance cancer-fighting effects. Unlike standard treatments like chemotherapy, which directly attack cancer cells, durvalumab and tremelimumab work by boosting the body's immune system to target and destroy cancer cells more effectively. Additionally, the trial explores different radiation doses—both high and low—to see how they can best complement the immunotherapies. This combination approach has the potential to offer a more targeted and potent attack on colorectal and lung cancer cells, potentially leading to better outcomes for patients.

What evidence suggests that this trial's treatments could be effective for metastatic colorectal or non-small cell lung cancer?

Research has shown that using the drugs durvalumab and tremelimumab with radiation therapy might help treat colorectal and non-small cell lung cancer. In this trial, participants will receive either high-dose or low-dose radiation therapy combined with durvalumab and tremelimumab, or the drug combination without radiation. Studies suggest that radiation can enhance the immune system's ability to fight tumors when used with these drugs. In some trials, patients with colorectal cancer who received this combination treatment lived for an average of 6.6 months, compared to 4.1 months for those who did not receive it. Specifically, in a particular group, 8.3% of patients experienced tumor shrinkage. While these results are encouraging, they indicate the treatment's potential rather than guaranteed outcomes. ^{6 7 8 9 10}

The combination of durvalumab and tremelimumab showed improved disease control rates in patients with head and neck squamous cell carcinoma compared to tremelimumab alone, indicating its potential efficacy in this cancer type.

The combination therapy had a tolerable safety profile, with no significant increase in treatment-related adverse events compared to monotherapy, suggesting it is a safe option for patients.

Tremelimumab, a CTLA-4 blocking antibody, was approved in the USA in October 2022 for treating unresectable hepatocellular carcinoma (uHCC) in combination with durvalumab, marking a significant advancement in cancer therapy.

In November 2022, tremelimumab was also approved for metastatic non-small cell lung cancer (mNSCLC) when combined with durvalumab and platinum-based chemotherapy, indicating its broad potential in treating various malignant tumors.

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.

In a study of 68 patients with locally advanced non-small cell lung cancer treated with intensity-modulated radiotherapy (IMRT), the administration of durvalumab significantly improved distant metastasis-free survival (DMFS), progression-free survival (PFS), and overall survival (OS), with hazard ratios of 0.31, 0.33, and 0.32 respectively.

The study also found that while grade 2 or higher radiation pneumonitis (RP) was associated with worse DMFS, reducing the incidence of RP could enhance patient outcomes, highlighting the importance of managing treatment-related side effects.

This phase II study aims to evaluate the safety and efficacy of combining the chemotherapy regimen FOLFOX (5-Fluorouracil, oxaliplatin, and leucovorin) with the immune checkpoint inhibitors durvalumab and tremelimumab in 48 patients with metastatic colorectal cancer (mCRC).

The study hypothesizes that this combination will improve progression-free survival (PFS) rates, expecting a PFS of 70.7% at 6 months, compared to a historical benchmark of 50%.

Durvalumab is an FDA-approved monoclonal antibody that enhances T-cell responses against cancer by blocking the PD-L1 pathway, specifically for patients with advanced urothelial carcinoma who have progressed after platinum-based chemotherapy.

The drug is currently being tested in phase III trials for various cancers, including lung and head and neck cancers, indicating its potential broad application in oncology beyond urothelial carcinoma.

Durvalumab: First Global Approval. Syed, YY.[2022]

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.

The combination of durvalumab and tremelimumab in cancer treatment is associated with a higher incidence of severe adverse events (32.6%) compared to durvalumab alone (23.8%), indicating increased safety concerns with the combination therapy.

Patients receiving the combination therapy also experienced higher rates of specific side effects such as diarrhea (15.6% vs. 8.1%), rash (11.1% vs. 6.5%), and treatment discontinuation (18% vs. 3%), highlighting the need for careful monitoring and patient counseling regarding these risks.

The DUART trial is a Phase II study investigating the safety and tolerability of durvalumab in patients with unresectable, stage III non-small-cell lung cancer (NSCLC) who cannot undergo chemotherapy due to poor performance status or other health issues.

Durvalumab, a PD-L1 blocking antibody, has shown clinical efficacy and a manageable safety profile in treating advanced non-small-cell lung cancer, especially in patients with ≥25% PD-L1 expression.

The drug is being evaluated in various treatment settings, including as a monotherapy and in combination with other therapies, showing promising results particularly after chemoradiation, although lower response rates were noted in patients with EGFR and ALK mutations.
