4D Pharma Inks Clinical Trial Collaboration And Supply Pact With Merck KGaA & Pfizer To Evaluate MRx0518 In Combo With Bavencio To Treat Urothelial Ca

4D pharma plc, a pharmaceutical company leading the development of live biotherapeutic products (LBPs), announced a clinical trial collaboration and supply agreement with Merck KGaA, Darmstadt, Germany and Pfizer Inc. for Bavencio (avelumab), the first and only immunotherapy approved as a first-line maintenance treatment for patients with locally advanced or metastatic urothelial carcinoma.

Bavencio is co-developed and co-commercialized by Merck KGaA, Darmstadt, Germany and Pfizer Inc.

Under the collaboration, 4D pharma intends to commence a clinical trial in 2021 to evaluate Bavencio in combination with MRx0518 as a first-line maintenance therapy for patients with locally advanced or metastatic urothelial carcinoma that has not progressed with first-line platinum-containing chemotherapy.

“With this second clinical trial collaboration for MRx0518 with a leading immune checkpoint inhibitor, 4D is able to evaluate MRx0518 in a new combination and earlier treatment setting. Following the promising data already generated in combination with checkpoint inhibitor pembrolizumab in refractory patients, and MRx0518 monotherapy data demonstrating single agent immuno-modulation presented last year at SITC, this collaboration allows us to continue to build a broad understanding of the safety and efficacy of MRx0518 across a range of solid tumors and stages of disease,” said Duncan Peyton, chief executive officer, 4D pharma. “The combination of MRx0518 with Bavencio has the potential to further enhance the positive clinical outcomes achieved by Bavencio for the significant number of patients in this treatment setting.”

MRx0518 is single strain live biotherapeutic product in development for the treatment of cancer. It is delivered as an oral capsule and stimulates the body’s immune system, directing it to produce cytokines and immune cells that are known to attack tumours. It is currently being evaluated in three clinical trials in patients with cancer. MRx0518-I-001 is a neoadjuvant monotherapy study in a variety of solid tumours and is being conducted at Imperial College (London, UK). MRx0518-I-002 is in combination with Keytruda (pembrolizumab) in patients whose disease has previously progressed on anti-PD-1 therapies. The Coordinating Investigator of the study is at The University of Texas MD Anderson Cancer Center, Houston, USA, with multiple additional sites in the US. The study is being conducted in collaboration with MSD, the tradename of Merck & Co., Inc., Kenilworth, NJ, USA. MRx0518-I-003 is in combination with preoperative radiotherapy in resectable pancreatic cancer. A fourth clinical trial of MRx0518 in combination with Bavencio (avelumab) in the first-line maintenance setting for urothelial carcinoma, conducted in collaboration with Merck KGaA, Darmstadt, Germany and Pfizer Inc., is expected to initiate in 2021.

Avelumab (Bavencio) is indicated in the US for the maintenance treatment of patients with locally advanced or metastatic urothelial carcinoma (UC) that has not progressed with first-line platinum-containing chemotherapy. Bavencio is also indicated for the treatment of patients with locally advanced or metastatic UC who have disease progression during or following platinum-containing chemotherapy, or have disease progression within 12 months of neoadjuvant or adjuvant treatment with platinum-containing chemotherapy.

Avelumab in combination with axitinib is approved in the US for the first-line treatment of patients with advanced renal cell carcinoma (RCC).

In the US, the FDA granted accelerated approval for Bavencio for the treatment of adults and pediatric patients 12 years and older with metastatic Merkel cell carcinoma (MCC). This indication is approved under accelerated approval based on tumor response rate and duration of response. Continued approval may be contingent upon verification and description of clinical benefit in confirmatory trials.  

Founded in February 2014, 4D pharma is a world leader in the development of Live Biotherapeutics, a novel and emerging class of drugs, defined by the FDA as biological products that contain a live organism, such as a bacterium, that is applicable to the prevention, treatment or cure of a disease.
