Immutep Limited (ASX: IMM) has signed a Clinical Trial Collaboration and Supply Agreement with Merck KGaA, Darmstadt, Germany and Pfizer for a new Phase I clinical study in patients with urothelial cancer, called INSIGHT-005.
We are very pleased to be deepening our collaboration with Merck KGaA, Darmstadt, Germany and Pfizer through this new study in patients with urothelial cancer, the sixth most common cancer in the US, who are in need of treatment options,” said Immutep CEO, Marc Voigt.
“INSIGHT-005 builds on the encouraging clinical efficacy and safety previously reported from the combination of efti and avelumab in various solid cancers, including deep and durable responses in patients with low or no PD-L1 expression and in indications that typically do not respond to immune checkpoint therapy.”
INSIGHT-005 will be an investigator-initiated explorative, open-label study evaluating the safety and efficacy of Immutep’s lead product candidate, efti, in combination with avelumab (BAVENCIO) in up to 30 patients with metastatic urothelial cancer.
The study will take place in Germany. The first patient is expected to be enrolled and dosed in H1 of calendar year 2023, after completing the necessary ethics and regulatory steps.
Urothelial cancer is a type of cancer in the bladder or urinary tract. In the US alone, it is estimated there will be 81,180 new cases of bladder cancer in 2022 and an estimated 17,100 people will die of this disease.
Avelumab is a checkpoint inhibitor that works by targeting and blocking a protein called PD-L1 on the surface of certain immune cells, activating the cells to find and kill cancer cells. It is approved in more than 60 countries around the world as a monotherapy for first-line maintenance treatment for adult patients with advanced urothelial carcinoma that has not progressed with first-line platinum-containing chemotherapy.
Avelumab is co-developed and co-commercialised by Merck KGaA, Darmstadt, Germany and Pfizer
Efti was previously evaluated in combination with avelumab via the INSIGHT-004 study in patients with advanced solid cancers, including colorectal, pleural mesothelioma, squamous anal cell, cervical, and gastroesophageal carcinomas. Immutep announced final data from INSIGHT-004 in June 2021, reporting encouraging efficacy signals from the combination with a response rate of 41.7% according to RECIST.
Under the Agreement, Immutep and Merck KGaA, Darmstadt, Germany will jointly fund the INSIGHT-005
