Arthur Tzianabos, Ph.D., is stepping down from his role as Homology’s CEO, handing the reins over to Albert Seymour, Ph.D., and transitioning into his new position as chair.  

Both Tzianabos and Seymour joined the genetic medicines company in 2016 as CEO/president and chief scientific officer, respectively. Now Seymour—who has previously worked at Shire and Pfizer—will take over Tzianabos' leadership roles. In conjunction with the transition, Kush Parmar, M.D., Ph.D., has stepped down as chair and member of Homology’s board.

The leadership shakeup follows several other recent changes at the biotech. A few weeks ago, Homology said it was voluntarily pausing enrollment of its phase 1/2 phenylketonuria (PKU) study of HMI-102 for financial reasons. The trial was slapped with an FDA hold earlier this year over elevated liver function tests, though the mandated pause was lifted in June.

Now, Homology is instead prioritizing the pheEDIT study of HMI-103, investigational gene editing product HMI-103 in adults with PKU. The switch is intended to extend Homology’s cash runway and produce some fresh data. 

“We expect that the multiple validating business development deals we have done and our recent pipeline prioritization will allow us to progress through several key milestones,” said Tzianabos. “The time is right to make this transition in leadership to Albert.” Release

UK biotech taps new CEO in hopes of taking field by Storm 

Storm Therapeutics 

Jerry McMahon, Ph.D., is taking the lead at Storm Therapeutics and forecasts that the company could have its RNA-modifying enzyme inhibitor into the clinic soon.
