Redx Pharma PLC said Wednesday that the investigational new drug application for its JZP815 treatment for solid tumors has been cleared by the U.S. Food and Drug Administration, triggering a milestone payment of $5 million from Jazz Pharmaceuticals PLC.

The London-listed drug discovery-and-development company said the payment stemmed from an agreement in which Jazz acquired Redx's pan-RAF inhibitor program. The company said the payment came on top of a previous $6.5 million payment already received, and that it remained entitled "To development, regulatory and commercial milestone payments as well as incremental tiered royalties in mid-single digit percentages, based on any future net sales."

The company said JZP815 was an investigational preclinical stage pan-RAF kinase inhibitor. A kinase inhibitor refers to a substance which blocks a type of enzyme known as kinase, and are helpful in keeping cancer cells from growing.

Shares at 0822 GMT were up 4.70 pence, or 7.7%, at 65.50 pence.
