Aileron Therapeutics Announces the Initiation of Patient Treatment in its First Clinical Ph1b/2 Trial of ALRN-6924 as a Myelopreservation Agent
Treatment uses a precision-medicine strategy to prevent the toxic side-effects of chemotherapy in patients with p53-mutated cancer, representing approximately 50% of all patients with cancer.
Management plans to expand its ongoing clinical myelopreservation trial to include two additional cohorts: an expansion cohort in small-cell lung cancer patients and a cohort in non-small-cell lung cancer patients.
Company expects to present key findings of the phase 1b portion of this myelopreservation trial in the 2nd quarter of 2020.
“Every year, millions of cancer patients undergo chemotherapy with the hope of prolonging their lives or being cured from a deadly disease. These patients have no choice but to suffer through the severe and life-threatening side effects that chemotherapy inflicts on their normal, healthy cells,” said Dr.
One basis for the potential anti-tumor effects lies in the fact that cancer cells frequently possess a mutated p53 gene, whereas normal cells, including immune system cells of cancer patients are not mutated, i.e., “p53-wildtype.” Importantly, the activation of p53-wildtype has been shown to have effects on the immune system that can enhance anti-tumor efficacy and ALRN-6924 is a first-in-class dual MDM2/MDMX-inhibitor that can activate p53-wildtype.
Aileron’s ongoing Phase 1b myelopreservation trial is designed to identify a recommended phase 2 dose for ALRN-6924 and evaluate the safety and efficacy of ALRN-6924 when administered to protect SCLC patients from toxicities caused by treatment with topotecan. The study will enroll up to 40 patients and will use existing standard gene tests to screen patients for p53-mutations as a biomarker-based patient selection strategy unique to ALRN-6924.

“Improving the tolerability of chemotherapy has the potential to reduce dose delays and dose reductions. Such optimized chemotherapy delivery and the potential stimulation of the immune system represent two independent mechanisms that inform our belief that treatment with ALRN-6924 will enhance the anti-tumor effects of chemotherapy,” said Dr.
Encouraged by the strong data from preclinical studies, the Company plans to expand its clinical program for ALRN-6924 in myelopreservation to include an additional Phase 1b cohort in non-small cell lung cancer patients treated with docetaxel. In addition, the company is planning a randomized expansion cohort of the Phase 1b SCLC trial to treat patients with alternating cycles of chemotherapy with and without ALRN-6924 (the “on/off” cohort). This “on/off” cohort is designed to provide a robust clinical proof of concept to demonstrate the effects of ALRN-6924 as a myelopreservative agent, as each patient will serve as his/her own control. After identifying a recommended phase 2 dose in the ongoing phase 1b trial, patient enrollment into these 2 new cohorts is expected to commence in the second quarter of 2020. The Company currently plans to reallocate resources from early-stage pipeline programs to accommodate the greater investment into the clinical development of ALRN-6924.
There are approximately 1.3 million cancer patients across the US and in the five largest European markets who receive chemotherapy each year. The company estimates that p53 mutations are found in about 50% of those cancer patients; therefore, an opportunity may exist to use ALRN-6924 to prevent or limit chemotherapy-related toxicities in more than 700,000 patients in the US and EU alone.
About ALRN-6924
ALRN-6924 is a first-in-class dual MDM2/MDMX inhibitor that is currently being evaluated in a Phase 2a clinical trial in combination with Pfizer’s palbociclib (Ibrance®) for the treatment of MDM2-amplified advanced solid tumors, and in a Phase 1b/2 clinical trial to evaluate ALRN-6924 as a myelopreservative agent to protect against chemotherapy-induced toxicities.
