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

  • Key Presentations

    • Poster presented at 2022 American Association for Cancer Research (AACR) Annual Meeting titled, “Exploration of MDM2 gene amplification, co-mutation status, and prognosis in solid tumors”

    • Poster presented at 2022 American Society of Clinical Oncology (ASCO) Annual Meeting titled “Using CDKN2A loss in the context of wildtype TP53 to predict sensitivity for the MDM2 inhibitor milademetan”

  • Phase 3 Dedifferentiated Liposarcoma Trial (MANTRA)

    • Enrollment now closed with 175 patients enrolled

    • Topline data anticipated in the first half of 2023

  • Phase 2 Basket Trial of Milademetan for MDM2-Amplified Advanced Solid Tumors (MANTRA-2)

    • Enrollment ongoing and interim data anticipated in the fourth quarter of 2022

  • Phase 2 Trial for Milademetan in Merkel Cell Carcinoma (MANTRA-3)

    • Trial commencement anticipated in the fourth quarter of 2022

  • Phase 1/2 Basket Trial in Advanced Solid Tumors Exhibiting Loss of the CDKN2A Gene (MANTRA-4)

    • Commencement of combination trial of milademetan with Roche’s FDA-approved IO therapy, atezolizumab, anticipated in the fourth quarter of 2022

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.

About Milademetan

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.

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-p53 complex that reactivates p53. In addition to milademetan, Rain is also developing a preclinical program that is focused on inducing synthetic lethality in cancer cells by inhibiting RAD52.
