REHOVOT, Israel & WILMINGTON, Del., Nov. 15, 2021 (GLOBE NEWSWIRE) -- Ayala Pharmaceuticals, Inc. (Nasdaq: AYLA), a clinical-stage oncology company focused on developing and commercializing small molecule therapeutics for patients suffering from rare and aggressive cancers, primarily in genetically defined patient populations, today reported financial results for the period ended September 30, 2021 and highlighted recent progress and upcoming milestones for its pipeline programs.

“As we gear up for multiple important milestones in 2022 across all of our clinical-stage programs in various indications, including desmoid tumors, triple negative breast cancer, adenoid cystic carcinoma and potentially multiple myeloma, we remain steadfast in our approach to developing gamma secretase inhibitors to treat these genetically defined cancers,” said Roni Mamluk, Ph.D., Chief Executive Officer of Ayala. “We are incredibly pleased with the safety and efficacy profile of AL101 for the treatment of recurrent/metastatic adenoid cystic carcinoma harboring Notch-activating mutations, as presented at ESMO in September, as well as the strong preclinical rationale for potential combination treatment in this indication and other tumor types. We also continued to progress our pivotal RINGSIDE trial evaluating AL102 for the treatment of desmoid tumors as enrollment continues across multiple sites globally and look forward to reporting preliminary results from this trial in mid-2022. In addition, we are very pleased with our ongoing collaboration with Novartis and the status of the study of our AL102 in combination with their anti BCMA agent for multiple myeloma.”

Recent Business Highlights and Upcoming Milestones:

• Published Two Case Studies Highlighting Clinical Activity of AL101 in Desmoid Tumors in Current Oncology: In September 2021, Ayala published two case studies of adult patients with desmoid tumors treated with AL101. Both patients experienced significant tumor burden and symptomatic and life-threatening disease due to disease bulk and location. With AL101 treatment, both subjects achieved long-lasting partial responses with a maximal decrease in tumor size from baseline of 41% after approximately 1 year (55 weeks) of treatment in Case One, and a maximal decrease in tumor size from baseline of 60% after about 1.6 years (82 weeks) of treatment in Case Two.
  
  
• On Track to Report Initial Interim Data from Part A of the Pivotal Phase 2/3 RINGSIDE Trial for the Treatment of Desmoid Tumors in Mid-2022: Enrollment continues to progress globally in the Phase 2/3 RINGSIDE Trial of AL102. Ayala expects to report an initial interim data read-out from part A of the trial in mid-2022, with part B of the study commencing thereafter.
  
  
• Phase 1 Trial of AL102 in Combination with Novartis’ BCMA Targeting Agent, WVT087 for the Treatment of Relapsed/Refractory Multiple Myeloma Continues to Progress: Enrollment progresses as planned in the Phase 1 combination trial of AL102 with Novartis’ investigational anti-B-cell maturation antigen (BCMA) agent, WVT078, for the treatment of relapsed and/or refractory (R/R) multiple myeloma (MM).
  
  
• Presented Preliminary Clinical Data from the Ongoing Phase 2 ACCURACY Trial and ACC at European Society for Medical Oncology (ESMO) Virtual Congress 2021: In September 2021, Ayala presented updated interim data from the 6mg cohort of its ongoing Phase 2 ACCURACY study of AL101 for the treatment of recurrent/metastatic adenoid cystic carcinoma (R/M ACC) harboring Notch activating mutations. The data demonstrated meaningful clinical activity of AL101 6mg monotherapy with a 70% disease control rate across 33 evaluable patients. Partial responses were observed in three subjects (9%) and stable disease was observed in 20 subjects (61%). The 6mg dose of AL101 was well tolerated with manageable side effects consistent with those observed in the 4mg cohort.
  
  
• Presented Preclinical Proof of Concept Data of AL101 in Combination with Approved Cancer Therapies in ACC at ESMO: In September 2021, Ayala also presented a preclinical study evaluating the potential of combination therapy of AL101 in PDX models of ACC, comparing the differential gene expression of ACC tumors versus normal matched tissue regardless of Notch activation status. AL101 in combination demonstrated significant tumor growth inhibition, including regressions, compared to each drug alone, and the study indicated that crosstalk between signaling pathways may increase the efficacy of AL101 in R/M ACC regardless of Notch mutational status.
  
  
• Phase 2 TENACITY Trial of AL101 for the Treatment of Triple Negative Breast Cancer Continues to Progress: Ayala continues to enroll patients in the Phase 2 TENACITY clinical trial of AL101, for the treatment of patients with Notch-activated recurrent or metastatic (R/M) triple negative breast cancer (TNBC). The Company expects to report preliminary data from this ongoing trial in 2022.
  
  

Third Quarter 2021 Financial Results

• Cash Position: Cash and cash equivalents were $40.8 million as of September 30, 2021, as compared to $42.0 million as of December 31, 2020.
