What is the purpose of this trial?

This trial explores how the drug durvalumab affects cancer, with a focus on whether adding prednisone can help manage side effects. Participants may have previously joined another trial using durvalumab, possibly with tremelimumab. The trial is open to individuals in Canada with a solid tumor that is advanced, metastatic (spread to other parts of the body), or inoperable. Participants should have previously tried durvalumab and experienced improvement without severe side effects. This trial requires participants to be in stable health and able to travel to the trial site for regular check-ups. As a Phase 2 trial, the research measures the treatment's effectiveness in an initial, smaller group, offering participants a chance to contribute to important cancer research.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications. However, you must have completed corticosteroid therapy at least 28 days before joining the study, and you should not be on any other investigational drugs or anti-cancer therapy concurrently.

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

Research shows that durvalumab is generally safe for many cancer patients. Some studies indicate it has a manageable safety profile, meaning side effects can be controlled. In patients with certain bladder cancers, durvalumab has shown significant benefits with usually tolerable side effects.

When combined with tremelimumab, the safety remains acceptable. Some patients experienced lung inflammation and infusion reactions, which occurred in a small number of people and were mostly mild. In rare cases, these reactions were more serious.

Overall, both durvalumab alone and with tremelimumab are well-tolerated by most patients. The treatment has been approved for other cancer types, providing some assurance about its safety. However, everyone is different, so discussing potential side effects with a healthcare provider is important. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Durvalumab is unique because it harnesses the power of the immune system to fight cancer by targeting the PD-L1 protein. Unlike traditional chemotherapy that directly kills cancer cells but often harms healthy cells too, Durvalumab helps the immune system recognize and attack cancer cells more effectively. Researchers are particularly excited about its potential to improve outcomes for patients with high-risk cancer profiles, offering a more targeted approach with possibly fewer side effects. Additionally, when combined with Tremelimumab, another immune checkpoint inhibitor, it may further enhance the immune response, providing a powerful one-two punch against cancer.

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

Research has shown that durvalumab can help treat several types of solid cancers. In some studies, patients taking durvalumab had a 25% lower risk of death compared to those receiving standard treatments. Additionally, nearly half of the patients lived for at least 6 months, with some living much longer. In this trial, some participants will receive durvalumab alone, while others will receive a combination of durvalumab and tremelimumab. Specifically, when combined with tremelimumab, about 31% of patients survived for three years. These findings suggest that durvalumab, either alone or with tremelimumab, can be an effective option for cancer treatment. ^{1 3 4 6 7}

Are You a Good Fit for This Trial?

This trial is for cancer patients in Canada who had a positive response to initial immunotherapy but stopped due to immune-related side effects, which have since resolved. They must not have received certain other treatments post-immunotherapy and should be stable enough with a life expectancy of at least 12 weeks.

Inclusion Criteria

I stopped immunotherapy due to side effects, which are now mild or gone, and I finished steroids over 28 days ago.

I will not donate blood during or for 3 months after the study.

My cancer responded well to initial immunotherapy and I haven't had immunotherapy for at least 6 months.

Exclusion Criteria

I have not received a live vaccine within 30 days before joining or before getting durvalumab.

I needed special medication to manage side effects from immune therapy.

I have an active stomach ulcer or inflammation.

Imiquimod 5% cream effectively cleared a large lentigo maligna in a 94-year-old woman within 19 weeks, demonstrating its potential as a treatment for skin lesions.

The treatment was guided by dermoscopy, which helped identify the most affected areas for biopsy and follow-up, ensuring precise monitoring of the lesion's response to therapy.

In a case study, 5% imiquimod cream was successfully used to treat a persistent melanoma in situ, leading to complete regression after 4 months of treatment with biopsies confirming the results.

This treatment may be a viable option for patients who cannot undergo surgery due to the size or location of the melanoma, advanced age, or other health issues, but requires careful long-term monitoring due to unknown recurrence rates.

Imiquimod is a novel drug that enhances the immune response in the skin by promoting the production of cytokines from macrophages, which helps fight off infections.

Currently, imiquimod is effectively used to treat cutaneous viral condylomas, and researchers are exploring additional potential therapeutic uses for this drug.

Imiquimod, when applied topically, significantly reduces angiogenesis (the formation of new blood vessels) in a murine model, indicating its potential anti-tumor activity, especially when using a 5% cream over three consecutive days.

The antiangiogenic effect of imiquimod is mediated by the cytokine IL-18, which promotes the production of IFN-gamma, a key inhibitor of angiogenesis, highlighting the importance of immune response in its mechanism of action.

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.

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.

In the phase 3 POSEIDON study involving 1013 treatment-naïve patients with metastatic non-small-cell lung cancer (NSCLC), the combination of tremelimumab, durvalumab, and chemotherapy significantly improved overall survival and progression-free survival compared to chemotherapy alone.

Patients receiving the combination treatment also experienced a longer time to deterioration in quality of life and various symptoms, indicating better overall health status compared to those on chemotherapy, supporting its use as a first-line treatment option.
