Jazz Pharmaceuticals to acquire Redx Pharma’s KRAS inhibitor program to expand oncology pipeline

Jazz Pharmaceuticals plc (Nasdaq: JAZZ) and Redx Pharma plc (AIM: REDX) have entered into a definitive agreement, marking a significant milestone in the development of new cancer treatments. Under this agreement, Jazz will acquire Redx’s promising KRAS (Kirsten rat sarcoma virus) inhibitor program, highlighting a strategic move to enhance Jazz’s early-stage oncology pipeline with innovative solutions for cancer patients facing high unmet medical needs.

The collaboration between Jazz and Redx Pharma is set to advance the development of preclinical KRAS inhibitor candidates, with Jazz Pharmaceuticals taking on all responsibilities for clinical development, regulatory filings, manufacturing, and commercialization activities. This partnership leverages the companies’ combined expertise in oncology, aiming to address the challenges of developing effective treatments for specific KRAS mutations—a well-validated but notoriously difficult target in cancer therapy.

Robert Iannone, Executive Vice President, Global Head of Research and Development at Jazz Pharmaceuticals, expressed enthusiasm about the acquisition, stating, “KRAS is a well-validated oncology target and there remains a high unmet need for innovation in this area. We plan to leverage our collective oncology development expertise to identify and advance the most promising molecules toward the clinic.”

Lisa Anson, Chief Executive Officer of Redx, also highlighted the significance of the collaboration: “This agreement will allow us to collaborate on the advancement of novel KRAS inhibitors and we look forward to supporting Jazz in progressing these candidates through IND-enabling studies.”

Jazz Pharmaceuticals will make an upfront payment of $10 million to Redx for the rights to the KRAS inhibitor program, which includes both G12D selective and pan-KRAS molecules. Additionally, Redx stands to receive up to $870 million in development, regulatory, and commercial milestones, plus tiered mid-single-digit percentage royalties on future net sales.

This strategic acquisition not only extends Redx’s cash runway into 2025 but also underscores the importance of partnerships in advancing differentiated molecules that address significant gaps in cancer treatment.

KRAS mutations are among the most common oncogenic drivers in various cancers, including colorectal, pancreatic, and lung cancers. Targeting these mutations with KRAS inhibitors could provide a crucial treatment avenue for a large patient population currently limited by existing options. The development of orally bioavailable agents with optimized target coverage represents a key opportunity in the next wave of cancer therapy, potentially transforming the treatment landscape for patients with KRAS-driven cancers.

The acquisition of Redx Pharma’s KRAS inhibitor program by Jazz Pharmaceuticals is a testament to the industry’s commitment to addressing complex challenges in cancer therapy. By focusing on a target like KRAS, known for its role in numerous cancers, this partnership has the potential to significantly impact the future of oncology treatment. The collaboration emphasizes the importance of innovation in drug development, particularly for conditions with substantial unmet needs.
