Disappointment for Alembic-backed Rhizen after partner TG Therapeutics takes Ukoniq off the US market amid wider regulatory scrutiny around the PI3K inhibitor class of drugs. The Indian firm, however, remains upbeat about the US business, which saw significant growth in the fiscal fourth quarter and has 15-plus launches lined up.

Disappointment for Alembic-backed Rhizen after partner TG Therapeutics takes Ukoniq off the US market amid wider regulatory scrutiny around the PI3K inhibitor class of drugs. The Indian firm, however, remains upbeat about the US business, which saw significant growth in the fiscal fourth quarter and has15-plus launches lined up.

2021 was another record-breaking year for novel product launches as COVID-19 continued to make an impact, but the industry’s response to the pandemic did not fully account for the acceleration seen in this strict measure of R&D productivity.

Rhizen is entitled to royalties on net sales of US FDA-approved Ukoniq, being commercialized by partner TG Therapeutics, and expects to take the lymphoma treatment to India. CEO suggests the first-in-class PI3K/CK1 epsilon inhibitor, discovered by Rhizen, bests competitors including Bayer's Aliqopa.
