Yumanity Therapeutics’ R&D Day Reviews Near-Term Value Drivers and Pipeline-Generating Discovery Engine

Clinical efforts expanding to three programs consisting of:

• the on-going Phase 1b portion of the YTX-7739 Phase 1 program in Parkinson’s disease patients with top line results expected in mid-2021
  
  

• initiation of Phase 1 studies of YTX-9184 for patients with dementia with Lewy bodies in 2H21
  
  

• initiation of a window of opportunity study of an SCD (stearoyl-CoA desaturase) inhibitor in glioblastoma multiforme patients in early 2022
  

BOSTON, May 17, 2021 (GLOBE NEWSWIRE) -- Yumanity Therapeutics (NASDAQ: YMTX), a biopharmaceutical company focused on the development of innovative, disease-modifying therapies for neurodegenerative diseases today held a virtual R&D Day. Management and David S. Russell, M.D., Ph.D., a guest researcher in neurodegenerative disorders from Yale University School of Medicine, discussed the cellular pathology underlying Parkinson’s disease (PD) and related disorders, how Yumanity’s lead clinical program, YTX-7739, has the potential to address a toxic biochemical pathway associated with PD, and how Yumanity’s discovery engine reveals additional novel biological targets with the potential to change the course of other neurodegenerative diseases.

“Yumanity has been a public company for about five months, and in that time the Company has made significant strides in advancing its pipeline,” said Richard Peters, M.D., Ph.D., President, Chief Executive Officer and Director of Yumanity Therapeutics. “Not only have we advanced our orally administered SCD inhibitor, YTX-7739, in clinical development but we have also demonstrated target engagement in humans at levels that reduced motor function deficits in a PD mouse model. Our first data from the Phase 1b part of our Phase 1 program in patients with PD are expected in the middle of this year. We expect to initiate clinical development of a second asset, YTX-9184 this year, honoring our commitment to introduce one new clinical program per year.”

“We are also excited to announce plans to initiate a third clinical program in early 2022 with a window of opportunity study targeting glioblastoma multiforme. This decision has been informed by compelling results of our SCD inhibitors in a preclinical animal model of the disease. Importantly, we expect our three clinical programs to achieve data read-outs within our expected current cash runway, which is into the third quarter of 2022.”

The R&D Day focused primarily on an up-to-date review of the clinical and pre-clinical data on YTX-7739.

• Phase 1 multiple ascending dose (MAD) study. This randomized, double-blind, placebo-controlled study with oral once-daily dosing of 15 mg or 25 mg for up to 28 days demonstrated that YTX-7739 was generally well tolerated in healthy volunteers. The drug was detected in the cerebrospinal fluid (CSF) at concentrations consistent with all pre-clinical animal models. YTX-7739 demonstrated dose dependent target engagement. After 14 days, the 15 mg dose reduced the plasma target engagement biomarker by about 20% while the 25 mg dose reduced the index by about 40%. Reductions in this range resulted in motor function improvement in animal models of PD.

• Target engagement is measured by a validated biomarker called the fatty acid desaturation index (FA-DI). YTX-7739 inhibits the enzyme SCD, which catalyzes the conversion of two saturated fatty acids to unsaturated fatty acids. Increased concentrations of unsaturated fatty acids alter cell membrane structure, resulting in alpha-synuclein aggregation, neuronal toxicity, and neurodegeneration. Inhibition of SCD by YTX-7739 reduces the concentration of unsaturated fatty acids, which in turn is reflected in reductions of the FA-DI biomarker.

• Phase 1 single ascending dose (SAD) study in healthy volunteers demonstrated that YTX-7739 is generally well tolerated. The drug candidate demonstrated a half-life of 47 to 72 hours suggesting once-daily dosing. YTX-7739 was also shown to cross the blood brain barrier with a single, oral dose. Despite evaluating doses of up to 400 mg, which is 10-fold greater than the modeled therapeutic dose expected to be evaluated in humans, no maximum tolerated dose was reached.
  
  

• The ongoing Phase 1b portion of the Phase 1 program is a randomized, double-blind, placebo-controlled study enrolling 30 PD patients with mild-to-moderate symptoms who are either treatment naïve or satisfactorily controlled with L-dopa. Two doses of YTX-7739, 20 mg and a second dose to be determined, will be dosed orally once daily for 28 days. Study endpoints include tolerability, pharmacokinetics and target engagement as measured by FA-DI. Several exploratory biomarkers will also be evaluated. Initial results from the study are expected to be announced in mid-2021.
  

“Today’s presentations highlight the progress Yumanity has made with YTX-7739 and demonstrates our improved understanding of neurodegenerative disease pathologies,” said Ajay Verma, Executive Vice President, Head of R&D of Yumanity Therapeutics. “Concurrently, we validated the potential of our unbiased drug discovery engine’s ability to identify multiple novel targets for drug development. With our Merck collaboration signed last year and multiple novel targets against different diseases of the central nervous system ready for development, we are extremely well positioned to build a multi-asset neurology product pipeline in the coming years.”

About YTX-7739
YTX-7739 is Yumanity Therapeutics’ proprietary lead small molecule investigational therapy designed to penetrate the blood-brain barrier and inhibit the activity of a novel target, stearoyl-CoA desaturase (SCD). SCD appears to play an important and previously unrecognized role in mitigating neurotoxicity arising from the effects of pathogenic alpha-synuclein protein aggregation and accumulation, which ultimately results in the death of neurons and the subsequent dysregulation of movement and cognition that afflicts patients living with these diseases. Through inhibition of SCD, YTX-7739 modulates an upstream process in the alpha-synuclein pathological cascade and has been shown to rescue or prevent toxicity in cellular and preclinical models. The company is assessing the potential utility of YTX-7739 as a disease modifying therapy for Parkinson’s disease.
