Aileron Therapeutics Announces Clinical Trial Collaboration with Dana-Farber/Boston Children’s Cancer and Blood Disorders Center

November 1, 2018

Investigator-Initiated Phase 1Trial of the Dual MDM2/MDMX Inhibitor ALRN-6924 in Pediatric Cancer

WATERTOWN, Mass., Nov. 01, 2018 (GLOBE NEWSWIRE) -- Aileron Therapeutics (NASDAQ:ALRN), the clinical-stage leader in the field of stabilized, cell-permeating peptides to treat cancer and other diseases, today announced an agreement with Dana-Farber/Boston Children’s Cancer and Blood Disorders Center for an open-label, multi-center, pediatric phase 1 clinical trial of ALRN-6924, Aileron’s lead clinical candidate.  In this investigator-initiated trial, pediatric patients with solid tumors will receive ALRN-6924 as a single agent, while pediatric patients with acute leukemia will be treated with a combination of ALRN-6924 and cytarabine.  In addition to these two dose-escalation cohorts, a third cohort of this trial will be biomarker-enriched with the intent of improving response rates with this precision medicine approach.

Principal Investigator, Steven DuBois, MD, of the Dana-Farber/Boston Children’s Cancer and Blood Disorders Center, commented: “Recently published preclinical data by Kimberly Stegmaier, MD, and Loren Walensky, MD, PhD, both from Dana-Farber/Boston Children’s Cancer and Blood Disorders Center, revealed that targeting MDM2 and MDMX had a selective cytotoxic effect in a range of pediatric cancers.  Together with our collaborators at several world-class pediatric clinical trial sites, we are committed to bringing this agent to the clinic for our pediatric patients with relapsed cancer.”

“I am particularly gratified to see the initiation of this trial,” said Dr. Walensky.  “Dana-Farber and I have deep roots in the discovery and development of this technology.  Seeing it deployed now in an effort to treat pediatric patients represents great progress.”

“MDMX and MDM2 play a role in many cancers, and our dual inhibitor of MDMX and MDM2, ALRN-6924, has shown in clinical trials that it can achieve responses in cancer patients,” said Manuel Aivado, MD, PhD and CEO of Aileron Therapeutics. “We are thankful for the opportunity to provide ALRN-6924 to relapsed and refractory pediatric patients in an effort to improve outcomes for these children.” 

About ALRN-6924
ALRN-6924 is a first-in-class, stabilized alpha-helical peptide that mimics the p53 tumor suppressor protein to disrupt its interactions with both its endogenous inhibitors, MDMX and MDM2. For p53 wild-type tumors, ALRN-6924 can restore p53-dependent tumor suppression. ALRN-6924 is currently being evaluated in multiple clinical trials for the treatment of solid and hematological cancers, including acute myeloid leukemia (AML), myelodysplastic syndrome (MDS), and peripheral T-cell lymphoma (PTCL).
