JZP815 / Jazz, Redx - LARVOL DELTA

Preclinical evaluation of the pan-RAF inhibitor JZP815 in Anaplastic Thyroid Carcinoma cell lines and Patient-derived Xenografts (ATA 2025) - "Although BRAF/MEK inhibition (dabrafenib and trametinib) drastically improved OS in patients with BRAFV600E-mutant (BRAFm) tumors, the latter only comprise 40% of ATC cases. We report on one of the first effective uses of a pan-RAF inhibitor in established ATC PDX models harboring either a BRAF or RAS driver mutation, with minimal in vivo toxicity. By targeting the RAF protein complex, the broadly applicable therapeutic potential for JZP815, through its promising antitumor activity, warrants continued preclinical evaluation in ATC."

Jazz Pharmaceuticals and Redx Announce Pan-RAF Inhibitor JZP815 to Enter Clinical Development (Jazz Pharma Press Release) - "Jazz Pharmaceuticals...and Redx...announce the U.S. Food and Drug Administration (FDA) has cleared the Investigational New Drug (IND) application for JZP815, a pan-RAF inhibitor for the treatment of solid tumors and hematologic malignancies that contain mutations in the MAPK pathway, enabling Jazz to proceed with initiating a clinical trial for JZP815. As a result, a milestone payment of USD $5 million from Jazz payable to Redx has been triggered. The milestone payment was triggered under the Agreement in which Jazz acquired Redx's pan-RAF inhibitor programme, announced on 10 July 2019....Jazz to initiate clinical development of JZP815 as a drug candidate for several types of difficult-to-treat solid tumours."

JZP815, a potent and selective pan-RAF inhibitor, demonstrates efficacy in RAF and RAS mutant tumor pre-clinical models (AACR 2022) - "JZP815 demonstrated enhanced activity when combined with inhibitors of other MAPK pathway components in both class 2 and class 3 mutant BRAF patient-derived tumor cells ex vivo, and KRAS mutant NSCLC and CRC xenografts in vivo. In summary, JZP815 is a potent and selective pan-RAF inhibitor that is orally bioavailable in multiple preclinical species with a well-behaved safety profile and pharmacokinetic properties predicted to provide drug exposure required for target engagement in humans, and therefore suitable for advancing into first-in-human trials."
