REHOVOT, Israel & WILMINGTON, Del., July 05, 2022 (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 tumors and aggressive cancers today announced positive interim results from Part A of the ongoing RINGSIDE Pivotal Phase 2/3 clinical trial evaluating AL102 in desmoid tumors. AL102 is a potent, selective, oral gamma-secretase inhibitor (GSI).
“We are very excited with the interim data from Part A of the RINGSIDE study, although early, demonstrating initial substantial anti-tumor activity for AL102 as a single agent as measured by MRI scans,” said Roni Mamluk, Ph.D., Chief Executive Officer of Ayala. “We are also encouraged with the safety data showing that AL102 appears to be well tolerated. We look forward to presenting a more advanced and comprehensive data set at a medical meeting later in the year. The results from Part A will be used to determine the dose of AL102 to be evaluated in Part B of RINGSIDE, the randomized portion of the study, which Ayala is on track to initiate in the third quarter of 2022.”
Interim Results as of the Cut-Off Date of May 1, 2022
- Patient enrollment in Part A of RINGSIDE was completed in February 2022. Patients were dosed in AL102 monotherapy cohorts of 1.2 mg (daily), 2mg (2 days on, 5 days off), or 4mg (2 days on, 5 days off).
- The activity of AL102 is being evaluated by change in tumor volume (central MRI readings) and response (per RECIST 1.1) determined by the investigator.
- MRI scans showed decreases in tumor size in most of the 13 patients who had reached the 16-week time point.
- One patient has reached a unconfirmed partial response at week 16 per RECIST.
- AL102 was well tolerated at all dose levels with no dose-limiting toxicities and no Grade 4/5 adverse events were observed.
- The most common treatment-related adverse events were Grade 1-2, including diarrhea, fatigue, skin rash, and nausea.
Gary Gordon, M.D., Ph.D., Chief Medical Officer of Ayala commented: “RINGSIDE is the first study to investigate AL102 exclusively in desmoid tumor patients and it has been designed to evaluate a range of different doses and dose schedules. Successful management of this disease will likely require chronic treatment and one of the key goals of our development program is to understand the optimal balance between efficacy, safety, and patient acceptability. We are encouraged by the early but very promising efficacy data and emerging favorable side effect profile for AL102 reported in these interim results.”
About the RINGSIDE study
The RINGSIDE pivotal Phase 2/3 study is a randomized multi-center trial. Part A of the study is evaluating the efficacy, safety, tolerability, and tumor volume by MRI after 16 weeks of AL102 in adult and adolescent patients with desmoid tumors. It enrolled 42 patients and is evaluating 3 doses of AL102. Patients who participated in Part A will be eligible to enroll into an open-label extension study at the selected dose, and long-term efficacy and safety will be monitored. Part B of the study will be double-blind, placebo-controlled, and will start immediately after dose selection from part A, enrolling up to 156 patients with progressive disease, randomized between AL102 or placebo. The study’s primary endpoint will be progression-free survival (PFS) with secondary endpoints including objective response rate (ORR), duration of response (DOR) and patient-reported Quality of Life (QOL) measures.

About Desmoid Tumors
Desmoid tumors, also called aggressive fibromatosis or desmoid-type fibromatosis, are rare connective tissue tumors that typically arise in the upper and lower extremities, abdominal wall, head and neck area, mesenteric root and chest wall with the potential to arise in additional parts of the body. Desmoid tumors do not metastasize, but often aggressively infiltrate neurovascular structures and vital organs. People living with desmoid tumors are often limited in their daily life due to chronic pain, functional deficits, general decrease in their quality of life and organ dysfunction. Desmoid tumors have an annual incidence of approximately 1,700 patients in the United States and typically occur in patients between the ages of 15 and 60 years. They are most commonly diagnosed in young adults between 30-40 years of age and are more prevalent in females. Today, surgery is no longer regarded as the cornerstone treatment of desmoid tumors due to high rate of recurrence post-surgery and there are currently no FDA-approved systemic therapies for the treatment of unresectable, recurrent or progressive desmoid tumors.

All statements contained in this press release that do not relate to matters of historical fact should be considered forward-looking statements, including statements relating to our development of AL102, the promise and potential impact of our clinical trial data, the timing and results of our clinical trials or readouts, the prevalence of desmoid tumors and the treatment required to manage the disease, and the design of our clinical trials. These forward-looking statements are based on management's current expectations. The words ”may,” “will,” “should,” “expect,” “plan,” “anticipate,” “could,” “intend,” “target,” “project,” “estimate,” “believe,” “predict,” “potential” or “continue” or the negative of these terms or other similar expressions are intended to identify forward-looking statements, although not all forward-looking statements contain these identifying words.
These statements are neither promises nor guarantees, but involve known and unknown risks, uncertainties and other important factors that may cause our actual results, performance or achievements to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements, including, but not limited to, the following: we have incurred significant losses since inception and anticipate that we will continue to incur losses for the foreseeable future. We are not currently profitable, and we may never achieve or sustain profitability; we will require additional capital to fund our operations, and if we fail to obtain necessary financing, we may not be able to complete the development and commercialization of AL101 and AL102; we have a limited operating history and no history of commercializing pharmaceutical products, which may make it difficult to evaluate the prospects for our future viability; we are heavily dependent on the success of AL101 and AL102, our most advanced product candidates, which are still under clinical development, and if either AL101 or AL102 does not receive regulatory approval or is not successfully commercialized, our business may be harmed; due to our limited resources and access to capital, we must prioritize development of certain programs and product candidates; these decisions may prove to be wrong and may adversely affect our business; the outbreak of COVID-19, may adversely affect our business, including our clinical trials; our ability to use our net operating loss carry forwards to offset future taxable income may be subject to certain limitations; our product candidates are designed for patients with genetically defined cancers, which is a rapidly evolving area of science, and the approach we are taking to discover and develop product candidates is novel and may never lead to marketable products; we were not involved in the early development of our lead product candidates, therefore, we are dependent on third parties having accurately generated, collected and interpreted data from certain preclinical studies and clinical trials for our product candidates; enrollment and retention of patients in clinical trials is an expensive and time-consuming process and could be made more difficult or rendered impossible by multiple factors outside our control; if we do not achieve our projected development and commercialization goals in the timeframes we announce and expect, the commercialization of our product candidates may be delayed and our business will be harmed; our product candidates may cause serious adverse events or undesirable side effects, which may delay or prevent marketing approval, or, if approved, require them to be taken off the market, require them to include safety warnings or otherwise limit their sales; the market opportunities for AL101 and AL102, if approved, may be smaller than we anticipate; we may not be successful in developing, or collaborating with others to develop, diagnostic tests to identify patients with Notch-activating mutations; we have never obtained marketing approval for a product candidate and we may be unable to obtain, or may be delayed in obtaining, marketing approval for any of our product candidates; even if we obtain FDA approval for our product candidates in the United States, we may never obtain approval for or commercialize them in any other jurisdiction, which would limit our ability to realize their full market potential; we have been granted Orphan Drug Designation for AL101 for the treatment of ACC and may seek Orphan Drug Designation for other indications or product candidates, and we may be unable to maintain the benefits associated with Orphan Drug Designation, including the potential for market exclusivity, and may not receive Orphan Drug Designation for other indications or for our other product candidates; although we have received Fast Track designation for AL101, and may seek Fast Track designation for our other product candidates, such designations may not actually lead to a faster development timeline, regulatory review or approval process; we face significant competition from other biotechnology and pharmaceutical companies and our operating results will suffer if we fail to compete effectively; we are dependent on a small number of suppliers for some of the materials used to manufacture our product candidates, and on one company for the manufacture of the active pharmaceutical ingredient for each of our product candidates; if we are unable to enter into new collaborations, or if these collaborations are not successful, our business could be adversely affected; enacted and future healthcare legislation may increase the difficulty and cost for us to obtain marketing approval of and commercialize our product candidates, if approved, and may affect the prices we may set; if we are unable to obtain, maintain, protect and enforce patent and other intellectual property protection for our technology and products or if the scope of the patent or other intellectual property protection obtained is not sufficiently broad, our competitors could develop and commercialize products and technology similar or identical to ours, and we may not be able to compete effectively in our markets; we may engage in acquisitions or in-licensing transactions that could disrupt our business, cause dilution to our stockholders or reduce our financial resources; and risks related to our operations in Israel could materially adversely impact our business, financial condition and results of operations.
These and other important factors discussed under the caption “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2021 filed with the U.S. Securities and Exchange Commission (SEC) on March 28, 2021 and our other filings with the SEC, could cause actual results to differ materially from those indicated by the forward-looking statements made in this press release. Any such forward-looking statements represent management's estimates as of the date of this press release. New risk factors and uncertainties may emerge from time to time, and it is not possible to predict all risk factors and uncertainties. While we may elect to update such forward-looking statements at some point in the future, except as required by law, we disclaim any obligation to do so, even if subsequent events cause our views to change. Although we believe the expectations reflected in such forward-looking statements are reasonable, we can give no assurance that such expectations will prove to be correct. These forward-looking statements should not be relied upon as representing our views as of any date subsequent to the date of this press release.
