Results in relapsed/refractory peripheral T-cell lymphoma (PTCL) demonstrate single-agent clinical proof-of-concept
Combination therapy dose-escalation with low-dose cytarabine (Ara-C) in myelodysplastic syndrome (MDS) patients who failed hypomethylating agents shows promising activity; expansion cohort enrolling
Single agent dose-escalation in relapsed/refractory AML continues
WATERTOWN, Mass., Dec. 04, 2018 (GLOBE NEWSWIRE) -- Aileron Therapeutics ALRN, the clinical-stage leader in the field of stabilized, cell-permeating peptides to treat cancer and other diseases, announced today the presentation of two posters at the 60th Annual American Society of Hematology (ASH) Meeting:
PTCL
Based on the interim data presented from this trial, Aileron has established ALRN-6924 single-agent proof-of-concept in PTCL, showing complete and partial remissions for single-agent therapy along with a favorable safety profile in the once-per-week dosing arm. For strategic reasons, Aileron has decided not to take the PTCL indication forward into a pivotal trial. Instead, based on the favorable ALRN-6924 and low-dose Ara-C combination therapy data, Aileron plans to focus on the potential synergy of ALRN-6924 in combination with other anti-cancer agents.

MDS
Aileron reported that in its Phase 1/1b clinical trial, ALRN-6924 in combination with low-dose Ara-C has shown clinical activity in patients with MDS who failed hypomethylating agents. The activity seen includes marrow complete responses (mCRs) and/or hematological improvements in four of six evaluable patients. Due to these data, Aileron has already begun dosing an expansion cohort of MDS patients who have failed hypomethylating agents with this combination and expects to report interim results in the first half of 2019.
AML
Aileron also reported an update on 26 patients with AML or MDS who received ALRN-6924 as single-agent. Two different dosing regimens, once weekly and three-times per week, were tested and no responses were seen when administering ALRN-6924 once weekly. Dose escalation in the three-times per week dosing arm continues.

Regarding the data presented at ASH, Manuel Aivado, MD, PhD, and CEO of Aileron Therapeutics commented: "We are pleased to be sharing these clinical ALRN-6924 results with the medical and scientific community. Having shown single-agent proof-of-concept in relapsed/refractory PTCL patients, and responses in combination with low-dose Ara-C in MDS patients who failed hypomethylating agents, where low-dose Ara-C alone shows little to no benefit, we are excited to advance ALRN-6924 into larger and more promising potential combination indications including low-dose Ara-C and ALRN-6924 for MDS as well as combinations with other approved chemotherapies and targeted agents for solid tumor patients."
In addition to our MDS expansion cohort, within the next few months, Aileron plans to initiate combination therapy cohorts in a variety of solid tumors, including a biomarker-guided trial with Pfizer's palbociclib in MDM2-amplified tumors.

About ALRN-6924
ALRN-6924 is a first-in-class, stabilized cell-permeating 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).
