Initiated dosing in the Phase 1b part of our MAD trial of YMTX-7739 in patients with Parkinson’s Disease; preliminary results expected by mid-year 2021

BOSTON, March 31, 2021 (GLOBE NEWSWIRE) — Yumanity Therapeutics (NASDAQ: YMTX), a clinical-stage biopharmaceutical company focused on the discovery and development of innovative, disease-modifying therapies for neurodegenerative diseases, today announced financial results for the full year ended December 31, 2020 and provided an overview of the Company’s recent corporate developments and upcoming milestones.

“Yumanity made important scientific and operational progress throughout the course of the last year,” said Richard Peters, M.D., Ph.D., President, Chief Executive Officer and Director of Yumanity. “Following our transition to a publicly-traded company in December, we achieved key clinical milestones for our lead Parkinson’s disease program, YTX-7739, including demonstrating safety, tolerability, and penetration in the cerebrospinal fluid with a single ascending dose (SAD) study of YTX-7739 in healthy volunteers, completing enrollment in the Phase 1a part of our multiple ascending dose (MAD) study in healthy volunteers, and initiating dosing in the Phase 1b part in Parkinson’s disease patients. Additionally, we strengthened our balance sheet with the completion of the reverse merger and a $33.6 million PIPE, adding a total of $68.7 million to our balance sheet, which will allow us to further accelerate growth towards our goal of delivering disease-modifying drugs to patients suffering from neurodegenerative diseases. We look forward to providing updates on a number of key milestones throughout the year, including results from the Phase 1a part of our MAD study of YTX-7739 in healthy volunteers expected in the beginning of the second quarter of 2021, preliminary results from the Phase 1b part of our MAD study of YTX-7739 in patients with Parkinson’s disease expected in mid-2021, and the start of a Phase 1 trial for our next program, YTX-9184, for patients with dementia with Lewy Bodies anticipated in the second half of 2021.”

Recent Corporate Developments

• Completed reverse merger with Proteostasis Therapeutics, Inc. on December 22, 2020 and commenced trading on the Nasdaq Capital Market on December 23, 2020, under the ticker symbol “YMTX”.
• Closed $33.6 million common stock private investment in public equity (“PIPE”) transaction concurrently with the closing of the reverse merger.
• Announced the results from the Phase 1, single-ascending dose (SAD) study in healthy volunteers of YTX-7739, a novel SCD inhibitor being developed for the treatment of Parkinson’s disease. No safety concerns were identified and YTX-7739 was found to be well tolerated with most adverse events being mild or moderate in severity. Consistent with preclinical data, YTX-7739 demonstrated clinically relevant drug concentrations in the cerebral spinal fluid (CSF).
• Completed enrollment of the Phase 1a part of our MAD study investigating the safety, tolerability, and pharmacokinetics of once daily oral administration of 2 doses of YTX-7739 in healthy volunteers.
• Initiated dosing of the Phase 1b part of our MAD study of YTX-7739 in patients with Parkinson’s disease. The Phase 1b part is expected to enroll 30 subjects and will collect safety, tolerability, pharmacokinetic and pharmacodynamic parameters including potential biomarkers of SCD activity and target engagement in the CSF, plasma, and other fluids or tissues.
• Presented results of a study of YTX-7739 that demonstrate pharmacological, physiological and behavioral pre-clinical proof of concept in a Parkinson’s disease (PD) mouse model. This oral presentation and two posters were presented at the 15^th Annual International Conference on Alzheimer’s and Parkinson’s Diseases (AD/PD™ 2021) Virtual Conference, March 9 to 14, 2021.

Upcoming Milestones

• The Company expects to report the results of the Phase 1a part of the MAD study of YTX-7739 in healthy volunteers in the beginning of the second quarter of 2021. Detailed clinical data from this Phase 1 study in healthy volunteers with YTX-7739 will be presented at a future medical conference.
• The Company remains on track to announce preliminary results from the Phase 1b part of the MAD study of YTX-7739 in patients with Parkinson’s disease by mid-year 2021.
• The Company anticipates initiating a Phase 1 trial of YTX-9184, a novel SCD inhibitor being developed for the treatment of dementia with Lewy Bodies, in the second half of this 2021.

2020 Financial Highlights:

• Cash position: As of December 31, 2020, cash, cash equivalents and investments were $85.3 million, compared to $15.4 million as of December 31, 2019. The increase in cash, cash equivalents and investments was primarily due to the receipt of $35.1 million in cash, cash equivalents, and investments from our merger with Proteostasis, $33.6 million in gross proceeds from the sale of common stock in our PIPE, $21.6 million in gross proceeds from the issuance of Class C preferred units prior to the merger, and $15 million in upfront payments received from Merck as part of the collaboration agreement, offset by operating expenses incurred during the year.
• Collaboration revenue: Revenue recognized in 2020 was GAAP revenue earned related to the upfront fee of $15.0 million for the Company’s collaboration agreement with Merck. Collaboration revenue was $6.9 million for the year ended December 31, 2020. Yumanity did not recognize collaboration revenue in 2019.
• Research and development expenses: Research and development expenses were $22.3 and $23.0 million for the years ended December 31, 2020 and 2019, respectively. The decrease in research and development expenses was primarily due to a $2.4 million decrease in platform and early stages research external costs, partially offset by a $1.3 million increase in manufacturing costs and GLP toxicology studies for YTX-9184 and $0.9 million in clinical and consulting costs for YTX-7739.
• General and administrative expenses: General and administrative expenses were $11.9 million and $7.1 million for the years ended December 31, 2020 and 2019. The increase was primarily attributable to an increase in professional services fees associated with the transactions listed above.
• Net loss: The company reported a net loss of $57.5 million and $31.2 million for the years ended December 31, 2020 and 2019, respectively, which is an increase of $26.3 million, resulting primarily from a $28.3 million charge for in-process research and development expenses in connection with our reverse merger with Proteostasis in December 2020.

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), that plays an important and previously unrecognized role in modulating neurotoxicity arising from the alpha-synuclein protein, a major driver of Parkinson’s disease and related neurodegenerative disorders. Misfolding and aggregation of alpha-synuclein triggers a cascade of events, ultimately resulting in neurotoxicity and the subsequent impairment of movement and cognition that afflicts patients living with this disease. 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 preclinical models. The company is assessing the potential utility of YTX-7739 in Parkinson’s disease.

About SCD
SCD is an enzyme that catalyzes fatty acid desaturation, the products of which are incorporated into phospholipids, triglycerides, or cholesterol esters. These lipid-related molecules regulate multiple diverse cellular properties and processes, including membrane structure and function, vesicle trafficking, intracellular signaling and inflammation. SCD expression is regulated by a transcription factor known as SREBF1, which has been identified in human genome-wide association studies as a risk factor for Parkinson’s disease. In preclinical models, SCD inhibition appears to normalize the dynamic interaction of pathological alpha-synuclein with membranes, which improves neuronal function and reduces toxicity, leading to enhanced neuronal survival. Alpha-synuclein-dependent disruption of membrane-related biological pathways, such as vesicle trafficking, is closely linked to the formation of Lewy body protein/membrane aggregations, a hallmark pathological feature of Parkinson’s disease.
