Rain Oncology (Rain Therapeutics) ^{Priced, Nasdaq: RAIN.XXX}

We are a clinical-stage precision oncology company developing therapies that target oncogenic drivers for which we are able to genetically select patients we believe will most likely benefit. This approach includes using a tumor-agnostic strategy to select patients based on their tumors’ underlying genetics rather than histology. Our lead product candidate, RAIN-32 (milademetan, formerly known as DS-3032), is a small molecule, oral inhibitor of mouse double minute 2 (MDM2), which is oncogenic in numerous cancers. We in-licensed RAIN-32 in September 2020 based on the results of a Phase 1 clinical trial, which demonstrated meaningful antitumor activity in an MDM2-amplified subtype of liposarcoma (LPS) and other solid tumors. Based on these data, we anticipate commencing a pivotal Phase 3 trial in LPS in the second half of 2021, a Phase 2 tumor-agnostic basket trial in certain solid tumors in the second half of 2021 and a Phase 2 trial in intimal sarcoma by early 2022. In addition to RAIN-32, we are also developing a preclinical program that is focused on inducing synthetic lethality in cancer cells by inhibiting RAD52.
