NEWARK, Calif., May 4, 2022 (GLOBE NEWSWIRE) -- Rain Therapeutics Inc. (NasdaqGS: RAIN), (Rain), a late-stage biotechnology company developing precision oncology therapeutics, today reports financial results for the first quarter ended March31, 2022, along with an update on the Company's key developments, business operations and upcoming milestones.
“Rain continues to make strong progress in its ongoing milademetan trials, with topline data from the Phase 3 MANTRA liposarcoma trial now anticipated in the first half of 2023. With a cash runway into the first half of 2024, we expect the milademetan clinical program to be well-funded. Additionally, we continue to anticipate interim data for theMANTRA-2 basket trial in MDM2-amplified advanced cancers in the fourth quarter of this year, and reporting patient responses, duration of response and safety in approximately 10 evaluable patients. Based upon our enrollment progress for MANTRA and MANTRA-2 thus far, we expect to commence the MANTRA-3 and MANTRA-4 studies in the fourth quarter of this year,” said Avanish Vellanki, co-founder and chief executive officer of Rain.

First Quarter Financial Results
For the three months ended March 31, 2022, Rain reported a net loss of $17.4 million, as compared to a net loss of $6.8 million for the same period in 2021.
Research and development (R&D)expenses were $13.6 million for the three months ended March 31, 2022, as compared to $5.3 million for the same period in 2021. The increase was primarily driven by the ongoing Phase 3 trial in dedifferentiated liposarcoma (MANTRA) and Phase 2 tumor-agnostic basket trial (MANTRA-2), as well as personnel costs. Non-cash stock-based compensation expenses included in R&D expenses were approximately $0.9 million in the three months ended March 31,2022, as compared to $0.1 million in the same period in 2021.
General and administrative (G&A) expenses were $3.9 million for the three months ended March 31, 2022, as compared to $1.5 million for the same period in 2021.The increase was primarily due to higher costs associated with Rain becoming a public company, including the costs of director and officer insurance, personnel, legal, outside consulting, and accounting and audit fees. Non-cash stock-based compensation expense included in G&A expenses were approximately $0.4 million for the three months ended March 31, 2022, as compared to $31,000 for the same period in 2021.
Total non-cash stock-based compensation expenses were approximately $1.2 million for the three months ended March 31, 2022, as compared to $0.2 million for the same period in 2021.
As of March 31, 2022, Rain had $123.2 million in cash, cash equivalents and short-term investments. Rain anticipates that its quarter-end cash position will provide runway into the first half of 2024 which we expect the milademetan program to be well-funded.
As of March 31, 2022, Rain had approximately 26.5 million shares of common stock outstanding.

Milademetan (also known as RAIN-32) is a small molecule, oral inhibitor of MDM2, which is oncogenic in numerous cancers. Milademetan has already demonstrated antitumor activity in an MDM2-amplified subtype of liposarcoma (LPS) and other solid tumors in a Phase 1 clinical trial, supported by a rationally-designed dosing schedule to mitigate safety concerns and widen the therapeutic window of MDM2 inhibition. Milademetan is being evaluated in an ongoing Phase 3 clinical trial in patients with LPS (MANTRA),as well as a Phase 2 tumor-agnostic basket trial in certain solid tumors(MANTRA-2). Rain anticipates commencing a Phase 2 clinical trial of milademetan (MANTRA-3), for the treatment of patients with wildtype p53 Merkel cell carcinoma who are also refractory to immune checkpoint inhibition (ICI), in the fourth quarter of 2022, as well as a Phase 1/2 clinical trial to evaluate the safety, tolerability and efficacy of milademetan in combination with Roche’s atezolizumab in patients with loss of cyclin-dependent kinase inhibitor 2A (CDKN2A) and wildtype p53 advanced solid tumors (MANTRA-4), in the fourth quarter of 2022. Milademetan has received Orphan Drug Designation from the U.S. Food and Drug Administration (FDA) for patients with LPS.
About Rain Therapeutics Inc.
Rain Therapeutics Inc. is a late-stage precision oncology company developing therapies that target oncogenic drivers for which it is able to genetically select patients it believes will most likely benefit. This approach includes using a tumor-agnostic strategy to select patients based on their tumors’ underlying genetics rather than histology. Rain’s lead product candidate, milademetan, is a small molecule, oral inhibitor of MDM2, which is oncogenic in numerous cancers. In addition to milademetan, Rain is also developing a preclinical program that is focused on inducing synthetic lethality in cancer cells by inhibiting RAD52.
