What data supports the effectiveness of the drug Dato-DXd + Durvalumab for breast cancer?

The TROPION-Breast01 study is evaluating the effectiveness of Dato-DXd in patients with inoperable or metastatic HR+/HER2- breast cancer, suggesting it may be a promising option for those who have limited treatment choices beyond chemotherapy. ^{1 2 3 4 5}

Is the combination of Dato-DXd and Durvalumab safe for breast cancer treatment?

The safety of Datopotamab deruxtecan (Dato-DXd) is being evaluated in ongoing studies for breast cancer, and it is considered a promising treatment option. While specific safety data for the combination with Durvalumab is not provided, Dato-DXd has shown manageable safety in other studies. ^{1 2 5 6 7}

What makes the Dato-DXd + Durvalumab treatment unique for breast cancer?

The Dato-DXd + Durvalumab treatment is unique because it combines an antibody-drug conjugate (Dato-DXd) with an immune checkpoint inhibitor (Durvalumab), potentially enhancing the immune system's ability to target and destroy cancer cells. This combination approach is novel compared to traditional chemotherapy, which does not typically involve immune system modulation. ^{8 9 10 11 12}

What is the purpose of this trial?

This is a Phase III, 2-arm, randomised, open-label, multicentre, global study assessing the efficacy and safety of neoadjuvant Dato-DXd plus durvalumab followed by adjuvant durvalumab with or without chemotherapy compared with neoadjuvant pembrolizumab plus chemotherapy followed by adjuvant pembrolizumab with or without chemotherapy in participants with previously untreated TNBC or hormone receptor-low/HER2-negative breast cancer.

Eligibility Criteria

Adults over 18 with Stage II or III breast cancer that's triple-negative or hormone receptor-low/HER2-negative can join. They need good bone marrow and organ function, an ECOG performance status of 0 or 1, a tumor sample for testing, and must follow local contraception rules.

Inclusion Criteria

My breast cancer is confirmed to be at Stage II or III and is either triple-negative or has low hormone receptors and is HER2-negative.

I am fully active or restricted in physically strenuous activity but can do light work.

My bone marrow and organs are functioning well.

Exclusion Criteria

I had cancer before, but it was treated successfully over 3 years ago with no current signs of return.

My cancer has spread to parts of my body far from where it started.

My HIV infection is not well controlled.

Findings from Research

Datopotamab deruxtecan (Dato-DXd) is a promising new treatment for patients with metastatic HR+/HER2- breast cancer, particularly for those who have limited options after endocrine therapy and chemotherapy.

The ongoing phase III TROPION-Breast01 study is comparing the efficacy and safety of Dato-DXd against standard chemotherapy in patients who have already received one or two lines of systemic treatment, aiming to improve outcomes in this challenging patient population.

TROPION-Breast01: Datopotamab deruxtecan vs chemotherapy in pre-treated inoperable or metastatic HR+/HER2- breast cancer. Bardia, A., Jhaveri, K., Kalinsky, K., et al.[2023]

In a real-world study of 143 patients with HER2+ metastatic breast cancer, trastuzumab deruxtecan (T-DXd) demonstrated a high overall response rate of 68% and a median progression-free survival of 16 months, confirming its efficacy in routine clinical practice.

The safety profile of T-DXd was consistent with previous studies, with 59% of patients experiencing any-grade toxicity, primarily nausea and neutropenia, but no new safety concerns were identified, indicating it is a well-tolerated treatment option.

Trastuzumab deruxtecan (T-DXd) has shown superior efficacy compared to capecitabine-based chemotherapy and T-DM1 in patients with metastatic HER2-positive breast cancer, based on the latest phase III data from the DESTINY-Breast02 and DESTINY-Breast03 trials.

T-DXd may also be effective as a neoadjuvant treatment for HER2-low breast cancer, suggesting its potential for broader applications in HER2-targeted therapies.

In the DESTINY-Breast01 trial with 184 patients, trastuzumab deruxtecan (T-DXd) showed a confirmed objective response rate of 62.0% and a median overall survival of 29.1 months, indicating its effectiveness in treating HER2-positive metastatic breast cancer after previous treatment with trastuzumab emtansine.

While T-DXd demonstrated sustained antitumor activity, it also had a notable safety profile, with 99.5% of patients experiencing drug-related adverse events, including a 15.8% incidence of interstitial lung disease/pneumonitis, highlighting the importance of monitoring for serious side effects.

In the DESTINY-Breast03 trial, trastuzumab deruxtecan (T-DXd) demonstrated superior progression-free survival and overall survival compared to trastuzumab emtansine (T-DM1) in patients with HER2-positive metastatic breast cancer, while maintaining quality of life (QoL) throughout treatment.

Patients receiving T-DXd experienced a median time to first hospitalization that was three times longer than those on T-DM1, indicating better overall health management and fewer hospital visits during treatment.

Trastuzumab deruxtecan (T-DXd) was evaluated for safety in 1457 patients across 8 clinical trials, revealing that gastrointestinal disorders and blood-related issues were the most common adverse events, with neutropenia being the most severe (21.4% incidence).

The study highlighted significant concerns regarding interstitial lung disease (10.9% incidence) and decreased left ventricular ejection fraction (1.2% incidence), suggesting that while T-DXd is generally well tolerated, these specific side effects require careful monitoring.

Trastuzumab deruxtecan (T-DXd) has shown significant antitumor activity in patients with HER2-positive advanced gastric cancer (AGC) who have previously undergone at least two therapies, leading to its approval in Japan and by the US FDA.

The treatment resulted in a higher objective response rate and longer overall survival compared to previous therapies, with an acceptable safety profile, indicating its potential as an effective option for this patient population.

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 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.

Durvalumab, an immunotherapy drug for non-small cell lung cancer (NSCLC), has shown significant activity and acceptable tolerability, especially in patients with at least 25% PD-L1 tumor expression, and has been established as a standard treatment following chemoradiation based on the PACIFIC study results.

While durvalumab is effective in wild-type EGFR and ALK patients, its efficacy is lower in those with EGFR mutations or ALK-positive status, highlighting the need for ongoing research into combination therapies and the management of treatment-related toxicity.

In the safety run-in of the IMMUNOBIL PRODIGE 57 trial involving 20 patients, the combination of durvalumab and tremelimumab with paclitaxel resulted in a high rate of dose-limiting toxicities (50%), including serious anaphylactic reactions and other severe adverse events.

Due to the safety concerns raised by the combination therapy, the trial will proceed with only the durvalumab and tremelimumab combination, indicating that the addition of paclitaxel may not be safe for patients with advanced biliary tract carcinoma.

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.
