AYLA Ayala Pharmaceuticals Inc

On September 16, 2021, Ayala Pharmaceuticals, Inc. (the “Company”) announced preliminary clinical data from the 6 mg cohort in its ongoing Phase 2 ACCURACY clinical trial of AL101 for the treatment of recurrent/metastatic adenoid cystic carcinoma (“R/M ACC”) harboring Notch-activating mutations and results from its preclinical study of AL101 in combination with approved cancer therapies for dual targeting of adenoid cystic carcinoma tumors.

Preliminary Safety and Efficacy Data from 6mg Cohort of ACCURACY Phase 2 Trial:

The Company presented new preliminary data from the 6mg cohort in its ongoing ACCURACY Phase 2 clinical trial evaluating the safety and efficacy of AL101 monotherapy for the treatment of patients with R/M ACC harboring Notch-activating mutations. The Phase 2 ACCURACY clinical trial is an open-label, single-arm, multi-center study to assess the clinical activity of AL101 using radiographic assessments of patients with R/M ACC demonstrating disease progression within 6 months prior to dosing.

As of July 9, 2021, all 42 patients enrolled in the 6mg cohort were treated and evaluable for safety and 33 were evaluable for efficacy.

Efficacy:

All evaluable patients were assessed for efficacy for a best response by investigators using RECIST 1.1 criteria.

Safety:

AL101 6mg dosed once weekly (“QW”) in patients with R/M ACC was well tolerated with manageable side effects consistent with those observed in the 4mg QW cohort with no new adverse events (“AEs”) specific to the 6mg cohort.

The Company plans to report additional data from the ACCURACY study in 2022.

Preclinical Results of AL101 Combined with Other Drugs for Dual Targeting of Notch Dysregulated Tumors:

In this preclinical study evaluating the potential of combination therapy of AL101 in PDX models of ACC, the Company compared the differential gene expression of ACC tumors versus normal matched tissue regardless of Notch activation status. Combination compounds were selected based on determination of the pathways that are implicated with approved oncology therapies, including inhibitors of Bcl2, HDAC, FGFR and CDK4/6. Based on a comparison of AL101 alone, each approved drug alone, and the combination of each drug with AL101, the Company observed additive or synergistic activity of AL101 combined with agents of various mechanisms of action. AL101 in combination demonstrated significant tumor growth inhibition, including regressions, compared to each drug alone, showing significant benefit with dual targeting of Notch and

other dysregulated pathways. Additionally, the study indicated that crosstalk between signaling pathways may increase the efficacy of AL101 in R/M ACC regardless of Notch mutational status. These preclinical results demonstrated a compelling rationale for potential expansion to a larger portion of ACC patients and to additional cancer indications.
