Proteostasis Therapeutics Reports Third Quarter 2020 Financial Results

BOSTON, Nov. 16, 2020 /PRNewswire/ -- Proteostasis Therapeutics, Inc. PTI, a clinical stage biopharmaceutical company, today announced financial results for the third quarter ended September 30, 2020.

In August 2020, Proteostasis and Yumanity Therapeutics, Inc. ("Yumanity"), announced the two companies had entered into a definitive merger agreement. If the merger is completed, Yumanity will become a wholly-owned subsidiary of Proteostasis, and the current stockholders of Yumanity will become the majority owners of Proteostasis' outstanding common stock. Completion of the merger is subject to the satisfaction of certain closing conditions, including approval of the transaction by Proteostasis' and Yumanity's stockholders. Upon the satisfaction or waiver of the terms and conditions required under the merger agreement, including receiving the requisite stockholder approvals, the combined company is expected to operate under the name Yumanity Therapeutics, Inc. and trade on the Nasdaq Capital Market under the ticker symbol "YMTX".  The transaction is expected to close in the fourth quarter of 2020, subject to approvals by stockholders of each company and other customary closing conditions.

Third Quarter 2020 Financial Results

Proteostasis reported a net loss of approximately $8.2 million for the three months ended September 30, 2020, as compared to a net loss of $12.8 million for the same period in the prior year.

Proteostasis recorded no revenue in the three months ended September 30, 2020 and 2019.

Research and development expenses for the three months ended September 30, 2020 were $1.2 million, as compared to $10.1 million for the same period in the prior year. The decrease in research and development expenses for the three months ended September 30, 2020 compared to the three months ended September 30, 2019 was primarily due to a decrease in clinical-related research activities.

General and administrative expenses for the three months ended September 30, 2020 were $4.5 million, as compared to $3.2 million for the same period in the prior year. The increase in general and administrative expenses for three months ended September 30, 2020 compared to September 30, 2019 was due primarily to an increase in professional fees in connection with the proposed merger with Yumanity Therapeutics.

Restructuring costs were $2.4 million for the three months ended September 30, 2020, consisting primarily of severance-related costs associated with a reduction in force undertaken in connection with the proposed merger with Yumanity Therapeutics. There were no restructuring costs for the three months ended September 30, 2019.

Cash, cash equivalents and short-term investments totaled $40.8 million as of September 30, 2020, compared to $69.5 million as of December 31, 2019. Proteostasis believes that its existing cash, cash equivalents and short-term investments are sufficient to fund its operations for at least 12 months from the date that its consolidated financial statements are issued and through the completion of the proposed merger with Yumanity Therapeutics.
