“Rain has achieved a number of important clinical milestones for milademetan including commencing two of the four planned trials in MDM2-dependent cancers. Rain dosed the first patient in the third quarter of last year and exceeded year-end 2021 targets for site activations for the pivotal, Phase 3 MANTRA trial in patients with liposarcoma and dosed the first patient in our Phase 2 MANTRA-2 basket trial in genetically selected patients with MDM2 gene amplification. We have also outlined two additional trials to start in the second half of this year, including the MANTRA-3 trial in patients with Merkel cell carcinoma, and our first combination trial MANTRA-4, with Roche's anti-PD-L1 antibody, atezolizumab, in patients with advanced cancers exhibiting loss of the CDKN2A gene,” said
Key Developments and Operational Updates

About Milademetan
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 second half of 2022, as well as a Phase 1 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 second half of 2022. Milademetan has received Orphan Drug Designation from the

Forward Looking Statements
Statements contained in this press release regarding matters that are not historical facts are “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Such forward-looking statements include statements regarding, among other things, Rain’s ongoing and planned studies for milademetan, including patient enrollment in the Phase 3 trial (MANTRA) and Phase 2 trial (MANTRA-2), timing for the commencement of the planned Phase 2 trial (MANTRA-3) and Phase 1 trial (MANTRA-4) and the timing for topline and interim data, and expectations regarding the sufficiency of capital resources. Because such statements are subject to risks and uncertainties, actual results may differ materially from those expressed or implied by such forward-looking statements. Words such as “plans,” “will”, “anticipates,” “goal,” “potential,” “expects” and similar expressions are intended to identify forward-looking statements. These forward-looking statements are based upon Rain’s current expectations and involve assumptions that may never materialize or may prove to be incorrect. Actual results could differ materially from those anticipated in such forward-looking statements as a result of various risks and uncertainties, which include, without limitation, risks and uncertainties associated with Rain’s business in general and limited operating history, difficulty enrolling patients in our clinical trials given the relatively small LPS patient population, Rain’s reliance on third parties to conduct and support its preclinical studies and clinical trials, and the other risks described in Rain’s Quarterly Report on Form 10-Q for the quarter ended
