AstraZeneca's Imfinzi Gets FDA Nod for Bladder Cancer Indication

In This Article:

AstraZeneca AZN announced that the FDA has approved its blockbuster drug, Imfinzi (durvalumab), for a bladder cancer indication in the United States.

Imfinzi is approved in combination with gemcitabine and cisplatin as a neoadjuvant treatment for muscle-invasive bladder cancer (MIBC), a type of bladder cancer that has spread into the muscle wall of the bladder. The regulatory filing for the drug was reviewed under the FDA’s Priority Review Pathway. This marks the first approval for Imfinzi for a bladder cancer indication.

AstraZeneca’s Imfinzi, either as a monotherapy or in combination with chemotherapy, is presently approved for stage III non-small cell lung cancer, extensive-stage small cell lung cancer, locally advanced or metastatic biliary tract cancer and endometrial cancer that is mismatch repair deficient and in combination with Imjudo in unresectable hepatocellular carcinoma in some countries. The drug has also recently been approved for limited-stage small cell lung cancer in the United States and the EU.

AZN’s Imfinzi Approval Based on NIAGARA Study Data

The FDA approval of AstraZeneca’s Imfinzi for the MIBC indication was based on data from the phase III NIAGARA study. Data from the study showed that Imfinzi, when used in combination with neoadjuvant chemotherapy before radical cystectomy and continued as an adjuvant monotherapy afterward, led to a 32% reduction in the risk of disease progression or recurrence compared to the standard treatment, which is neoadjuvant chemotherapy with radical cystectomy alone. The study also demonstrated a 25% reduction in the risk of death in patients treated with Imfinzi.

MIBC patients face high recurrence rates and poor prognosis even after undergoing aggressive treatments like cystectomy, which creates demand for new options for MIBC treatment. This is the first time an immunotherapy regimen has been approved in a perioperative setting, which makes Imfinzi a potential transformative option for the MIBC patient population.

Regulatory applications seeking approval for Imfinzi for similar use are under review in the EU, Japan and several other countries.

Year to date, AZN stock has risen 12.2% compared with the industry’s 3.5% growth.
