AstraZeneca’s Imfinzi Plus Chemotherapy Approved for Endometrial Cancer



AstraZeneca’s groundbreaking cancer drug Imfinzi, when combined with chemotherapy, has received U.S. FDA approval for the treatment of specific types of endometrial cancer. This approval signifies a pivotal development in the treatment options available for patients battling this prevalent and often deadly disease.

FDA Approval and Clinical Trial Success

On June 17, AstraZeneca announced that the U.S. Food and Drug Administration approved Imfinzi (durvalumab) in combination with chemotherapy for adult patients with primary, advanced, or recurrent endometrial cancer that is mismatch repair deficient (dMMR). This approval follows a successful late-stage clinical trial that demonstrated a 58% reduction in the risk of disease progression or death for patients treated with Imfinzi and chemotherapy compared to those receiving chemotherapy alone.

The Role of Immunotherapy in Cancer Treatment

Dave Fredrickson, Executive Vice-President of AstraZeneca’s Oncology Business Unit, highlighted that this approval marks a new standard of care for endometrial cancer patients. Immunotherapy combined with chemotherapy is emerging as a potent treatment strategy, offering new hope for patients with mismatch repair deficient disease.

Impact of Endometrial Cancer

Endometrial cancer is the fourth most prevalent cancer among women in the United States. In 2022 alone, more than 66,000 women were diagnosed with this cancer, and nearly 12,000 succumbed to it. The approval of Imfinzi provides a significant advancement in the fight against this disease, potentially improving survival rates and quality of life for many patients.

Imfinzi’s Mechanism and Benefits

Imfinzi is an immunotherapy drug that works by blocking the PD-L1 protein, which allows cancer cells to evade the immune system. When combined with chemotherapy, Imfinzi enhances the body’s immune response against cancer cells, improving the efficacy of the treatment. The combination of Imfinzi with chemotherapy drugs carboplatin and paclitaxel, followed by maintenance therapy with Imfinzi alone, has shown promising results in delaying disease progression.

Future Prospects for AstraZeneca

The FDA’s approval of Imfinzi for endometrial cancer not only broadens the treatment options for patients but also strengthens AstraZeneca’s position in the oncology market. The success of Imfinzi in clinical trials and its subsequent approval underscores the potential of immunotherapy in treating various cancers. AstraZeneca continues to explore the benefits of Imfinzi in other cancer types, aiming to provide innovative treatments that improve patient outcomes.


The FDA’s approval of AstraZeneca’s Imfinzi combined with chemotherapy represents a significant milestone in cancer treatment. This new therapeutic option offers hope to many endometrial cancer patients, highlighting the importance of continued research and innovation in the field of oncology. As AstraZeneca advances its portfolio of cancer treatments, the prospects for patients battling this disease continue to improve.
