Belharra Therapeutics Inc., an early stage firm which is pioneering a new approach to chemoproteomics, has already found an influential backer for the distinctive way it systematically probes the interactions between small-molecule ligands and the proteins to which they bind.

Momentum is building at Jnana Therapeutics Inc. The firm has raised $107 million in a series C round and banked another $50 million up front from a new drug discovery and development pact with Roche Holding AG, which could potentially deliver significant near-term milestones and more than $2 billion in future milestone payments. It also commenced recruitment onto a first-in-human study of its lead drug candidate, JNT-517, an inhibitor of the phenylalanine transporter SLC6A19, which is in development for phenylketonuria.

Jnana Therapeutics Inc. closed a $50 million series B round and took the covers off its lead program, a small-molecule inhibitor of the solute carrier transporter SLC6A19, which it is prepping for clinical trials in phenylketonuria (PKU).

DUBLIN – Roche Holding AG has joined Jnana Therapeutics Inc. in its quest to drug the human repertoire of solute carrier (SLC) metabolite transporters as a means of tackling a swath of immune-mediated and neurological diseases. The Basel, Switzerland-based pharma is paying Boston-based Jnana $40 million up front and could pay over $1 billion more in research funding, preclinical, development and commercial milestones, as well as sales royalties, in a multitarget deal.
