"All cancer patients undergoing chemotherapy – still the standard of care for most patients – experience chemotherapeutic side effects to varying degrees, from unpleasant to fatal. Utilizing a biomarker strategy, we are developing ALRN-6924 as a selective chemoprotective agent to shift the paradigm from accepting these side effects to preventing them for patients with p53-mutated cancer regardless of type of cancer or chemotherapy," said Manuel Aivado, M.D., Ph.D., President and Chief Executive Officer at Aileron. "In 2022, we expect several key milestones may propel us toward this vision, including our planned initiation of a clinical trial in breast cancer patients receiving neoadjuvant chemotherapy in the first half of the year with interim results in the fourth quarter, as well as planned interim and topline data readouts for our ongoing NSCLC trial in the second and fourth quarters, respectively."
Aileron is developing ALRN-6924 to selectively protect healthy cells in patients with p53-mutated cancers to reduce or eliminate chemotherapy-induced side effects. Nearly 1 million patients each year are diagnosed with a p53-mutated cancer in the US alone, and Aileron employs a precision medicine approach to exclusively treat those patients with p53-mutated cancers who are receiving chemotherapy. ALRN-6924 is designed to selectively protect these patients’ healthy cells from chemotherapy without protecting cancer cells. This novel concept is known as selective chemoprotection. The reduction or elimination of multiple chemotherapy-induced side effects is expected to enhance tolerability of chemotherapy, which is expected to result in fewer dose reductions and delays of chemotherapy, and that is expected to improve efficacy of chemotherapy.
2022 Strategic Priorities and Business Update
Initiate clinical trial in neoadjuvant (pre-operative) breast cancer in 1H22, with interim results in 4Q22. Aileron plans to initiate a new clinical trial in 1H22 to evaluate ALRN-6924 to protect against chemotherapy-induced bone marrow and other toxicities in ER+/HER2- breast cancer patients treated with a doxorubicin + cyclophosphamide and docetaxel chemotherapy regimen, also known as ‘AC-D’. The Phase 1b trial will enroll up to 30 patients in a parallel group design trial with a dose expansion cohort. Aileron will provide more details on the planned neoadjuvant breast cancer trial design at the time of trial initiation.
Advance ongoing NSCLC trial to interim (20-patient) and topline (60-patient) readouts, in 2Q22 and 4Q22, respectively. Aileron is currently enrolling patients in the US and EU with advanced p53-mutated NSCLC undergoing treatment with first-line carboplatin plus pemetrexed with or without immune checkpoint inhibitors. As previously guided, Aileron anticipates reporting interim results on 20 patients in 2Q22, and topline results on 60 patients in 4Q22. Aileron has dosed the first 10 patients in the trial and plans to conduct a blinded safety evaluation on these patients after one cycle in 1Q22, as previously guided.
Continue to progress ongoing Healthy Volunteer Study. Aileron is continuing to progress its ongoing Phase 1 pharmacology study which is evaluating ALRN-6924’s induction of p21-induced cell cycle arrest in healthy, normal bone marrow cells and other cell types in healthy volunteers receiving ALRN-6924. The company presented initial data from the study in 2021, confirming the drug’s novel p53 biomarker-driven mechanism of action, as well as its pharmacodynamic effects, including time to onset, magnitude and duration. The aim of the study is to develop a universal dosing regimen for ALRN-6924 for use as a chemoprotection agent across a range of chemotherapies and p53-mutated cancers. Aileron anticipates reporting additional findings from the study this year.
Expanded patent portfolio in 2021 with issuance of 11 new foreign and U.S. patents. Aileron was issued 7 new international patents and 4 U.S. patents over the past 12 months, including new patent protection for ALRN-6924 in China. These newly issued patents add to Aileron’s robust intellectual property portfolio, which includes over 170 U.S. and foreign patents, with another 47 applications in prosecution. These patents and applications include ALRN-6924 methods of manufacture, methods of use, drug product formulations, and compositions of matter (COM). The COM patent in the US expires in 2033 with up to 5 additional years subject to patent term extensions. Of note, Aileron maintains exclusive rights to its proprietary peptide drug technology and ALRN-6924 worldwide.
