Following deep cuts, Yumanity strikes a deal to sell drugs to J&J, hands the keys to Genentech-partnered Kineta
Yumanity has found that “strategic alternative” it started searching for early this year as its share price shriveled, forcing deep staff cuts.
The suffering biotech has agreed to sell off most of its pipeline — including a partially-held Phase I Parkinson’s drug, dubbed YTX-7739, and unpartnered discovery-stage neuroscience product candidates — to J&J for $26 million in cash. And it’s executing a reverse merger with the private biotech Kineta, which will wind up with the public listing and Yumanity’s Merck-partnered ALS/frontotemporal lobar degeneration program.
YTX-7739 marks Janssen’s first clinical-stage Parkinson’s asset, a company spokesperson told Endpoints News in an email. The drug caught the Big Pharma’s eyes because of its “potential to be the first oral-disease modifying therapy in PD.” Janssen doesn’t intend to test it beyond PD, at this time, unlike the original owner’s ambitions of potentially testing the drug in glioblastoma multiforme and other diseases.
In the reverse merger, Kineta will end up with 85% ownership of the combined operations with its new name on the marquee from now on. The future of the new Kineta is expected to be supported by a PIPE financing of undisclosed amount from Growth & Value Development Inc.
Yumanity was founded by the late Susan Lindquist — an MIT professor and expert in protein folding who died in 2016 — and Tony Coles about eight years ago, amid great hopes for their R&D approach to some tough disease. But it didn’t play out as they had hoped it would.
Yumanity’s battered stock $YMTX jumped 50% before the opening bell Monday, to $2.12 apiece, but it’s still well below the $16 level that Yumanity traded at a year ago. The biotech had $17.5 million in cash and investments as of March 31.

“We are excited that our lead clinical-stage neurology asset and unpartnered assets will continue to be developed and we are very enthusiastic about Kineta’s innovative oncology pipeline,” Yumanity CEO Richard Peters said in a press release.
The new Kineta will be led by Kineta’s execs: CEO Shawn Iadonato and President Craig Philips.
Yumanity previously merged with cystic fibrosis developer Proteostasis Therapeutics in 2020, but the company’s stock cratered about 91% over the course of 2021 as the biotech struggled to cement its turnaround story.

Now, in its latest merger, Yumanity will be a shell of itself as the focus will land on Kineta’s preclinical immunotherapy asset known as KVA12.1, which is slated to enter human trials in the fourth quarter of this year, the companies said on an investor call Monday. The drug will eventually be tested in combination with other therapies across NSCLC, colorectal and ovarian cancers.
A CD27-targeted monoclonal antibody will enter a Phase I study in the fourth quarter of 2023, and IND-enabling studies will begin around the same time for a CD24-targeted mAb, the companies said in the investor presentation.
Kineta has been through multiple changes over the years. The Seattle biotech once thought about making RIG-I agonist antivirals for the Zika virus around the time of the 2016 Rio Olympics. It also wanted to develop a vaccine adjuvant system for the flu. The biotech also went into the clinic for Lassa fever and neuropathic pain.
Kineta had secured $15 million upfront and had the potential to reel in another $505 million from Pfizer in a December 2018 deal.
“We sold the RIG-I program to Pfizer and are no longer in an active collaboration,” a Kineta spokesperson told Endpoints News in an email.
Another Big Pharma deal came through in a $359 million tie-up signed with Roche’s Genentech in April 2018. The collaboration expanded in October 2020 for a new non-opioid for chronic pain. A Genentech option on the Phase I asset, KCP506, is on the calendar for the second half of 2023, Kineta said in the investor presentation.
Last month, Yumanity also agreed to terminate its 30,000 square-foot laboratory lease in Boston. The lease was scheduled to end in 2028, but that will now happen on July 31.
