- Preliminary findings from ongoing Phase 1 healthy volunteer study will include data relating to mechanism of action; optimal dose; and time to onset, duration and magnitude of pharmacodynamic effects
- Final data from completed Phase 1b study in patients with small cell lung cancer (SCLC) receiving topotecan supporting best-in-class potential of ALRN-6924
BOSTON, Sept. 10, 2021 (GLOBE NEWSWIRE) -- Aileron Therapeutics (Nasdaq: ALRN), a chemoprotection oncology company focused on fundamentally transforming the experience of chemotherapy for cancer patients, today announced two upcoming poster presentations at the European Society of Medical Oncology (ESMO) Virtual Congress 2021, which is being held September 16-21, 2021. In these posters, Aileron will present preliminary data from its ongoing Phase 1 study of ALRN-6924 in healthy volunteers and final data from its completed Phase 1b study of ALRN-6924 in patients with small cell lung cancer (SCLC) receiving second-line topotecan treatment. Aileron is developing ALRN-6924 to selectively protect healthy cells in patients with cancers that harbor p53 mutations to reduce or eliminate chemotherapy-induced side effects while preserving chemotherapy’s attack on cancer cells, an emerging concept known as chemoprotection. ALRN-6924, a first-in-class MDM2/MDMX dual inhibitor, is designed to activate p53, which in turn upregulates p21, a known inhibitor of the cell replication cycle.
“We are excited to share preliminary findings from our ongoing study of ALRN-6924 in healthy volunteers as well as final results from our completed Phase 1b study of ALRN-6924 in patients with small cell lung cancer at the upcoming ESMO Congress,” said Manuel Aivado, M.D., Ph.D., President and CEO of Aileron. “These findings support the design of our ongoing randomized, double-blind, placebo-controlled study of ALRN-6924 in patients with non-small cell lung cancer and are helping us plan for future clinical studies of ALRN-6924 in multiple p53-mutated cancers and types of chemotherapy.”

About the Phase 1 Study in Health Volunteers
Aileron is conducting a multi-part Phase 1 pharmacology study in healthy volunteers to evaluate the pharmacokinetics (PK) and pharmacodynamics (PD) of ALRN-6924. Aileron will present the findings from Parts 1 and 2 of the study at ESMO. The objectives of these first two parts are to determine a dose of ALRN-6924 that initiates p53-mediated transcriptional regulation and yields transient cell cycle arrest via p21 induction in human bone marrow with minimal signal for apoptosis (Part 1), and to determine the time to onset, magnitude, and duration of bone marrow PD effects (Part 2). The study is ongoing, and Aileron anticipates presenting additional findings at a later date.
About the Phase 1b Study in Patients with p53-Mutated SCLC
In October 2020, Aileron presented positive clinical data from the Phase 1b trial in SCLC demonstrating clinical proof-of-concept that treatment with ALRN-6924 resulted in a protective effect against severe neutropenia, anemia and thrombocytopenia in patients with p53-mutated SCLC treated with second-line topotecan. The final data set from this trial, which Aileron will present at ESMO, includes results from 13 additional patients, including two new cohorts of seven patients receiving 0.3 mg/kg ALRN-6924 given six hours before topotecan; four patients receiving 0.2 mg/kg ALRN-6924 given 24 hours before topotecan; and two new patients receiving 0.3 mg/kg ALRN-6924 given 24 hours before topotecan. These data are in line with the proof-of-concept data previously presented and with Aileron’s expectation that administering ALRN-6924 at 0.3 mg/kg and 24 hours before topotecan is the optimal dose and schedule in this patient population.
About Aileron Therapeutics
Aileron is a clinical stage chemoprotection oncology company focused on fundamentally transforming the experience of chemotherapy for cancer patients. ALRN-6924, our first-in-class MDM2/MDMX dual inhibitor, is designed to activate p53, which in turn upregulates p21, a known inhibitor of the cell replication cycle. ALRN-6924 is the only reported chemoprotective agent in clinical development to employ a biomarker strategy, in which we exclusively focus on treating patients with p53-mutated cancers. Our targeted strategy is designed to selectively protect multiple healthy cell types throughout the body from chemotherapy while ensuring we do not protect cancer cells. As a result, healthy cells are spared from chemotherapeutic destruction while chemotherapy continues to kill cancer cells. By reducing or eliminating multiple chemotherapy-induced side effects, ALRN-6924 may improve patients’ quality of life and help them better tolerate chemotherapy. Enhanced tolerability may result in fewer dose reductions or delays of chemotherapy and the potential for improved efficacy.
Nearly 1 million patients in the U.S., across all cancer types, are diagnosed annually with p53-mutated cancer. Our vision is to bring selective chemoprotection to patients with p53-mutated cancers regardless of type of cancer or chemotherapy. Visit us at aileronrx.com to learn more.
