NEWARK, Calif., Aug. 04, 2022 (GLOBE NEWSWIRE) -- Rain Therapeutics Inc. (NasdaqGS: RAIN), (Rain), a late-stage biotechnology company developing precision oncology therapeutics with a lead product candidate, milademetan, an oral, small molecule inhibitor of the MDM2-p53 complex that reactivates p53, today reported financial results for the second quarter and six months ended June 30, 2022, along with an update on the Company’s key developments, business operations and upcoming milestones.
“Rain’s focus on clinical execution of the milademetan program was evidenced by the completion of enrollment of our Phase 3 MANTRA trial five months ahead of previous guidance. We believe the rapid enrollment in MANTRA reflects a patient population in LPS that may be larger than expected, and that exhibits a significant unmet medical need,” said Avanish Vellanki, co-founder and chief executive officer of Rain. “With the ongoing enrollment in the pan-tumor MANTRA-2 study, additional clinical studies anticipated to commence before year-end, and alongside a cash runway into mid-2024, we believe Rain is in a strong position to generate significant new data for the milademetan franchise.”
Key Developments, Presentations, Operational Updates and Upcoming Milestones
Second Quarter Financial Results
For the three and six months ended June 30, 2022, Rain reported a net loss of $17.6 million and $35.0 million, respectively, as compared to a net loss of $8.2 million and $15.0 million for the same periods in 2021, respectively.
Research and development (R&D) expenses were $14.3 million and $27.8 million for the three and six months ended June 30, 2022, respectively, as compared to $5.5 million and $10.8 million for the same periods in 2021, respectively. The increases were 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 $1.2 million and $2.1 million in the three and six months ended June 30, 2022, respectively, as compared to $0.6 million and $0.8 million in the same periods in 2021, respectively.
General and administrative (G&A) expenses were $3.5 million and $7.4 million for the three and six months ended June 30, 2022, respectively, as compared to $2.7 million and $4.2 million for the same periods in 2021, respectively. The increases were primarily due to higher costs associated with Rain becoming a public company, including personnel, legal, outside consulting, and accounting and audit fees. Non-cash stock-based compensation expense included in G&A expenses were approximately $0.2 million and $0.6 million for the three and six months ended June 30, 2022, as compared to $0.2 million for each of the same periods in 2021.
Total non-cash stock-based compensation expense were approximately $1.4 million and $2.7 million for the three and six months ended June 30, 2022, respectively, as compared to $0.8 million and $1.0 million for the same periods in 2021, respectively.
As of June 30, 2022, Rain had $105.7 million in cash, cash equivalents and short-term investments. Rain anticipates that its quarter-end cash position will provide runway into mid-2024 and therefore believes the milademetan program is well-funded.
As of June 30, 2022, Rain had approximately 26.5 million shares of common stock outstanding.
Second Quarter 2022 Results Conference Call and Webcast Details
Replay of the call will be available by visiting the “Events” section of the Rain website after the conclusion of the presentation and will be archived on the Rain website for 30 days.
Milademetan (also known as RAIN-32) is an oral small molecule inhibitor of the MDM2-p53 complex that reactivates p53. 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.
