What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests the effectiveness and safety of durvalumab (an immunotherapy) combined with other cancer treatments for advanced triple-negative breast cancer (TNBC). It examines various combinations, including durvalumab with paclitaxel (a chemotherapy drug), and some new treatments, to determine which are most effective. The trial targets women with TNBC that has either spread or cannot be surgically removed, and who have not yet received treatment for their metastatic cancer. Participants must have at least one measurable tumor that has not been treated with radiation. As a Phase 1, Phase 2 trial, it aims to understand how the treatment works in people and measures its effectiveness in an initial, smaller group.

Will I have to stop taking my current medications?

The trial protocol does not specify if you must stop taking your current medications, but if you are in Arm 2, you cannot take certain medications that affect liver enzymes (CYP3A4, CYP2C9, CYP2D6) within 2 weeks before starting the study. Also, if you are in Arm 6, 7, or 8, you cannot use chloroquine or hydroxychloroquine within 14 days before starting treatment.

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

Research shows that durvalumab, often used with other drugs, is generally safe. For instance, when combined with datopotamab deruxtecan, it achieved a high success rate in treating patients with triple-negative breast cancer, and no major safety issues emerged. Durvalumab with paclitaxel has also undergone extensive study. Some patients experienced serious side effects like a low white blood cell count, but these were manageable.

Adding capivasertib to durvalumab and paclitaxel also appears well-tolerated. Previous studies on this combination did not find significant safety concerns. For the combination of durvalumab, paclitaxel, and oleclumab, safety monitoring confirmed it is generally safe.

Lastly, durvalumab with trastuzumab deruxtecan mostly causes mild to moderate side effects, with many patients experiencing only mild reactions. These findings suggest that the treatments tested in this trial are generally well-tolerated, based on previous research. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about these treatments because they combine durvalumab, an immunotherapy drug, with other agents like paclitaxel, datopotomab deruxtecan, and others, to potentially enhance their effectiveness against breast cancer. Unlike traditional chemotherapy, durvalumab works by unleashing the immune system to target cancer cells more effectively. For example, adding datopotomab deruxtecan combines an antibody-drug conjugate that delivers chemotherapy directly to cancer cells, potentially reducing side effects and improving outcomes. Additionally, these combinations explore new pathways, like inhibiting PD-L1, which might help in treating breast cancer more efficiently than existing treatments. This innovative approach could offer new hope for patients, especially those with PD-L1 positive status.

What evidence suggests that this trial's treatments could be effective for metastatic triple negative breast cancer?

Research has shown that combining durvalumab with datopotamab deruxtecan, one of the treatment arms in this trial, may effectively treat triple-negative breast cancer. In one study, 79% of patients experienced tumor shrinkage, indicating a strong response. Another arm in this trial involves the combination of durvalumab and paclitaxel, where studies found that 44% of patients showed no signs of cancer after treatment. Although less information exists on the combinations of durvalumab with capivasertib and oleclumab, these are also being tested in separate arms of this trial for their potential benefits. Lastly, the combination of trastuzumab deruxtecan with durvalumab, another arm in this trial, delayed cancer progression for an average of 15 months. Each of these combinations offers hope for improving treatment against this challenging type of breast cancer. ^{1 4 6 7 8}

Published Research Related to This Trial

Immune checkpoint inhibitors (ICIs), particularly durvalumab, have significantly improved treatment outcomes for patients with advanced non-small cell lung cancer (NSCLC), establishing them as the standard of care either alone or with chemotherapy.

Durvalumab is specifically approved as a consolidation treatment after chemo-radiotherapy for stage III NSCLC, highlighting its role in enhancing patient prognosis.

Update on Targeted Therapies for Advanced Non-Small Cell Lung Cancer: Durvalumab in Context. Gullapalli, S., Remon, J., Hendriks, LEL., et al.[2020]

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.

Durvalumab in non-small-cell lung cancer patients: current developments. Mezquita, L., Planchard, D.[2018]

The combination of MEDI0680 and durvalumab was found to be safe and tolerable in patients with advanced clear-cell renal cell carcinoma, but it did not show improved efficacy compared to nivolumab alone, with objective response rates of 16.7% for the combination and 23.8% for nivolumab.

Both treatment groups had a median progression-free survival of 3.6 months, and a notable percentage of patients (23.8% in the combination group) discontinued treatment due to adverse events, highlighting the need for careful monitoring of side effects.

In a study of 121 patients with stage III non-small cell lung cancer treated with durvalumab, those with over 50% PD-L1 expression had significantly better outcomes, with a 1-year survival rate of 97% compared to 73% and 78% for lower expression groups.

Higher PD-L1 expression (>50%) was strongly associated with improved progression-free survival and overall survival, indicating that PD-L1 levels could be a key factor in predicting the effectiveness of durvalumab treatment.

Tumor PD-L1 expression is associated with outcomes in stage III non-small cell lung cancer (NSCLC) patients treated with consolidation durvalumab. Jazieh, K., Gad, M., Saad, A., et al.[2022]

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.

Safety and efficacy of durvalumab (MEDI4736) in various solid tumors. Yang, H., Shen, K., Zhu, C., et al.[2022]

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]

The combination of durvalumab and tremelimumab was studied in 19 articles involving 2052 patients with solid tumors, showing some benefits over traditional chemotherapy in certain tumor types.

However, this combination did not consistently outperform durvalumab alone, indicating that while it may have potential, further research with larger and better-designed studies is needed to clarify its efficacy.
