• ATX101 is designed to provide extended pain relief after surgery, reducing the need for opioids and improving patient recovery
• Phase 2b registration trial is assessing the efficacy and safety of ATX101 for post-surgical pain management in total knee replacement patients and is currently enrolling across U.S. clinical sites
• Maruishi Pharmaceutical, Allay’s partner in Japan also has enrolled first several patients in Phase I/II open-label study

SAN JOSE, CA, February 18, 2025 (BUSINESSWIRE) –  Allay Therapeutics, a clinical-stage biotechnology company pioneering ultra-sustained analgesic products to transform post-surgical pain management and recuperation, today announced that the first patient has been dosed in its Phase 2b registration trial evaluating ATX101 for the treatment of post-surgical pain following total knee replacement (TKA) surgery.  ATX101 is a novel investigational analgesic that provides extended pain relief after surgery, reducing the need for opioids and improving patient recovery.

“We’re thrilled to achieve this important milestone with the patients dosed in our Phase 2b registration trial of ATX101,” said David Hewitt, Chief Medical Officer at Allay Therapeutics. “This trial is a significant step forward on our path to changing the paradigm of postoperative pain management by providing a simplified locally targeted solution that provides sustained analgesia in the weeks following surgeries. Building on promising data from our earlier dose-ranging studies, we are excited to see how ATX101 can help improve patient outcomes, reduce opioid use and improve function more rapidly than currently available therapies.”

The Phase 2b registration trial of 200 participants undergoing total knee arthroplasty (replacement, or TKA surgery) is being conducted at multiple U.S. sites and is a three-arm, randomized, controlled study evaluating treatment with ATX101 1,500 mg versus placebo and bupivacaine active comparator. A prior dose-ranging Phase 2b trial achieved clinically meaningful durable treatment effects with ATX101 versus standard-of-care bupivacaine based on pain intensity out to four weeks, with less use of opioids and meaningful improvement in functional activities up to 60 days following surgery.

Allay Therapeutics’ Japanese partner Maruishi Pharmaceutical has also dosed the first patient in January in a Phase I/II multi-center open-label safety study of ATX101 in Japan. Initial clinical data from both studies is expected to be shared in the second half of 2025.

About ATX101

ATX101 is a novel investigational configuration of an approved, well-characterized, validated intracellular sodium ion channel blocker, bupivacaine, and a biopolymer that has been designed to provide weeks of pain relief following total knee arthroplasty (TKA, or replacement), a common orthopedic surgery. ATX101 has a high density of drug within its small footprint to allow for ultra-sustained analgesia. It is placed in minutes at the end of standard surgery to deliver its analgesic effect over weeks before eventually dissolving into water and carbon dioxide. The simple procedure does not require specialized training and is intended to replace the existing complex mix of analgesic products used for shorter-term pain management in the post-surgical setting. ATX101 is an investigational product that has not been approved by the U.S. Food and Drug Administration.

• Breakthrough Therapy designation supported by results from a Phase 2 dose-ranging trial
• Planned Phase 2B registrational trial expected to enroll 200 participants at U.S. sites

SAN JOSE, CA, December 3, 2024 (BUSINESSWIRE) —  Allay Therapeutics, a clinical-stage biotechnology company pioneering ultra-sustained analgesic products to transform post-surgical pain management and recuperation, today announced that the U.S. Food and Drug Administration (FDA) has granted Breakthrough Therapy designation (BTD) for its lead investigational product ATX101 for treatment of postsurgical pain following TKA procedures in adults.  This BTD was granted based on clinical data from a Phase 2 exploratory dose-ranging trial for the treatment of Post-Surgical Pain following Total Knee Arthroplasty (TKA), or replacement.

“We’re delighted that the FDA granted Breakthrough Therapy designation for ATX101, which we believe recognizes the clear unmet need for novel non-opioid therapies that may provide extended pain relief to patients in the weeks following TKA surgeries. Despite decades of development efforts, current treatment methods provide only a few days of pain relief with complicated treatment regimens.  ATX101 is designed to provide patients weeks of pain relief enabling an active recovery with less opioids used and less opioid-related side effects and risks,” stated Sharon Hall, SVP of Regulatory Affairs at Allay Therapeutics. “This BTD will allow us to work closely with the FDA to efficiently advance the ATX101 development program through its clinical and regulatory milestones, and eventual NDA filing. Our planned Phase 2B registrational trial will start early next year with leading investigative pain centers in the U.S. to fully assess ATX101’s potential impact on patient’s pain and recovery following painful total knee replacement surgeries.”

The BTD is supported by Allay’s recently completed dose-ranging Phase 2 exploratory trial (n=112) of ATX101 as compared to (SOC) active comparator, bupivacaine. Data showed that ATX101 achieved sustained, clinically meaningful post-surgical pain relief for up to four weeks following TKA compared to the standard of care. Treatment with ATX101 resulted in a decrease in opioid use as well as a decrease in opioid-related side effects and meaningful improvements in functional activities and satisfaction up to 60 days following surgery.

FDA’s Breakthrough Therapy program is designed to expedite development review of drugs intended to treat a serious or life-threatening condition for which preliminary clinical evidence indicates the drug may demonstrate substantial improvement over available therapies.  Under the designation, the FDA provides intensive guidance, organizational commitment involving senior managers, and eligibility for rolling review and other actions to expedite review.  To learn more about Breakthrough Therapy  designation, click here.

•  Planned Phase 2b trial expected to enroll 200 participants at U.S. sites
• Study design and protocol informed by recent positive discussions with U.S. Food and Drug Administration
• Prior dose-ranging Phase 2b trial demonstrated durable treatment effects with ATX101 versus standard-of-care bupivacaine based on pain intensity out to four weeks, with less use of opioids for pain relief while achieving faster improvement in function

SAN JOSE, CA, June 12, 2024 (BUSINESSWIRE) —  Allay Therapeutics, a clinical-stage biotechnology company pioneering ultra-sustained analgesic products to transform post-surgical pain management and recuperation, today announced plans to proceed to a Phase 2b registration trial of its lead investigational product ATX101. The clinical trial builds on a strong foundation of clinical data from prior exploratory dose-ranging studies and is informed by recent discussions with the U.S. Food and Drug Administration (FDA) on the study design and protocol. If successful, this Phase 2b registration trial would support a new drug application (NDA) filed with the FDA.

“We’re excited to reach this important milestone following a productive dialogue with the FDA to establish a clear path forward to evaluating ATX101 and further demonstrating its potential as a post-surgical pain management therapeutic,” said Adam Gridley, Chief Executive Officer at Allay Therapeutics. “The encouraging data from our recently completed Phase 2b dose-ranging trial provide compelling support for our registration clinical trial design, and we look forward to working closely with investigators to fully assess ATX101’s impact on patient recovery and recuperation following total knee replacement.”

The Phase 2b registration trial of 200 participants undergoing total knee arthroplasty (replacement, or TKA surgery) will be conducted at multiple U.S. sites and is a three-arm randomized controlled study evaluating treatment with ATX101 1,500 mg versus placebo or a bupivacaine active comparator. The primary endpoint will be the area under the curve (AUC) of pain intensity as measured by the NRS-Rest over several weeks, with secondary endpoints evaluating reduction in use of opioids, opioid-related side effects, and improvement in physical function. The trial will assess and inform additional functional and health economics endpoints for an anticipated global Phase 3 registration study that would support an NDA filing.

Allay’s recently completed dose-ranging Phase 2b trial enrolled 112 participants before being concluded early based on a positive interim analysis. Data showed that ATX101 achieved sustained, clinically meaningful post-surgical pain relief for up to four weeks following TKA compared to the standard of care (SOC) active comparator, bupivacaine. Treatment with ATX101 resulted in a decrease in opioid use as well as a decrease in opioid-related side effects and meaningful improvements in functional activities up to 60 days following surgery.

The U.S. and Singapore-based startup has developed an implant for treating pain after knee surgery. It is inserted directly into the knee and may relieve pain for up to three weeks – previous solutions work for a maximum of three days. The technology may promote the recovery process and make it possible to reduce or eliminate the administration of common opioid painkillers such as morphine or oxycodone. Biodegradable polymers from Evonik are the key to the success of this new type of pain therapy: they ensure that the active ingredients are delivered over a longer period.

Knee replacements are one of the most frequently performed surgeries worldwide. The consequences of the procedure are often painful with pain that lasts for weeks, hindering recovery. Therefore, doctors use painkillers such as opioids after these surgeries. However, they have numerous side effects, including a high risk of dependence. Allay’s products, which are in the early stages of clinical development, are expected to offer an alternative. “Our products may provide patients with pain relief exactly when they need it most – for weeks instead of days. This would significantly improve and accelerate the recovery process,” says Adam Gridley, Chief Executive Officer (CEO) of Allay Therapeutics.

Evonik sees great potential in this technology. “Allay’s pain products can become a game-changer in postoperative pain management. They may reduce the problems that opioids bring, such as dependence, further hospitalization, lengthy rehabilitation, and overall costs to the healthcare system,” says Bernhard Mohr, head of Evonik Venture Capital.

Allay’s products are thin implants about the size of a coin. They are placed around the implanted knee joint at the end of the surgery and consist of a proven local non-opioid anesthetic and polymers from Evonik. The local anesthetic blocks the transmission of pain signals to the spinal cord, thus stopping the pain impulse before it reaches the brain. Until now, the duration of such systems was limited to a few days. Allay has succeeded in extending the delivery to up to three weeks through a novel active ingredient-polymer architecture. Evonik’s polymers play a key role here: they ensure that the active ingredient is delivered in a controlled fashion over a long period. During this process, the implants gradually dissolve and are broken down by the body. The technology can be easily adapted for other orthopedic and soft tissue surgeries and Allay is currently developing a portfolio of products based on this drug-polymer architecture.

Evonik has more than 60 years of experience in technologies for the targeted delivery of medical agents. Its Health Care Business Line is a global innovation partner for the pharmaceutical industry. “We are pleased to be able to support our partner Allay in developing this promising innovation. It can fundamentally change pain management and take away patients’ fear of surgery,” says Paul Spencer, Head of the Drug Delivery & Products Product Line in Evonik’s Health Care Business Line.  Health Care supplies the biodegradable polymer processed in the Allay implant.

With more than 1.2 million knee joint interventions per year, the United States is the most relevant market for Allay’s technology. The volume for the treatment of very severe, postoperative pain is estimated at $10 billion. The dramatic increase in opioid addicts in the U.S., referred to as the opioid crisis, reinforces the relevance of alternative pain therapies.

Allay Therapeutics was founded in 2016. The company is headquartered in San Jose in the U.S. state of California with Research and Development facilities in Singapore, where the technology was developed. “We are delighted to have one of the world’s leading specialty chemical companies on our side with whom we can further develop our technology,” emphasizes Adam Gridley of Allay.

– First clinical data to demonstrate non-opioid pain relief lasting two weeks after one administration, where current post-surgical pain products are effective for a maximum of three days

– Significant reductions in pain and opioid usage relative to standard of care

– Clinical candidate for support of total knee replacement surgery, ATX-101, to move into Phase 2b clinical study this year

– Proprietary technology platform expanding to deliver a new category of ultra-sustained localized pain products for diverse conditions

MENLO PARK, Cali., May 13, 2021— Allay Therapeutics, a clinical-stage biotechnology company pioneering ultra-sustained analgesic products to transform post-surgical pain management and recuperation, today announced the first-ever clinical data showing non-opioid pain relief lasting two weeks after a single administration. Current post-surgical pain products have shown effectiveness for a maximum of three days after a single dose. The data come from a Phase 1b/2a clinical study of Allay’s first candidate, ATX-101, in development to treat pain after total knee arthroplasty (replacement), or TKA, surgery. TKA surgery is performed over one million times each year in the United States and is associated with a lengthy, painful recovery often managed with significant opioid usage. ATX-101 is a small dissolvable product candidate incorporating the validated local analgesic bupivacaine. It is designed to be incorporated into surgery to deliver continual, localized pain relief that matches the pain trajectory patients typically experience after TKA surgery.

Allay Therapeutics was formed with a singular goal: to allay patients’ fears of extended painful recoveries and reliance on opioids after surgery. Allay’s technology platform combines validated local analgesics and biopolymers in dissolvable candidates designed to deliver pain relief within a targeted site over days to weeks, or longer. Changes to the drug-biopolymer configuration and manufacturing process allow tuning of the amount of drug delivered and differing rates of release for each product candidate. This tunability permits a wide range of potential therapeutic profiles for different kinds of pain.

“Pain management innovation has stalled for too long in the face of the enormous need created by the opioid crisis and a growing number of patients undergoing painful surgeries where rapid recuperation is crucial for long-term outcomes. Allay was founded to deliver a gentler longer-term recovery for patients and ease the burden of pain management and opioid use for the healthcare system,” said Adam Gridley, chief executive officer of Allay Therapeutics. “We believe these unprecedented clinical data could be the start of a new era of ultra-sustained pain management. Our focus now is a Phase 2b trial of ATX-101 to enroll over 300 patients in the United States, as well as the advancing of our pipeline across several new areas of pain representing major unmet needs globally.”

Currently, approved post-surgical pain products using local anesthetics have demonstrated effectiveness for a maximum of three days. They are often challenging to administer consistently and have variable outcomes. They are insufficient to fully support recuperation, which often results in supplementary opioid use, readmissions and extended recovery, all resulting in significant additional healthcare costs. Opioids are short-term medications which act systemically on the body and have a range of side effects – including respiratory depression, greater pain sensitivity and the significant risk of abuse and addiction – which have fueled a major health crisis in the United States and beyond.

The recently completed Phase 1b/2a clinical study of ATX-101 was an open-label dose-ranging study at two Australian clinical sites which evaluated 22 patients undergoing TKA with ATX-101 implants incorporating approximately 250 mg, 750 mg and 1,500 mg doses of bupivacaine, respectively, of which 15 patients received the 1,500 mg dosage. The study was designed to evaluate safety and pharmacokinetics of ATX-101 in adult subjects in primary unilateral TKA while also examining dose response, pain scores, opioid use and overall impact on quality of life during recuperation. Originally planned to enroll up to 30 patients with up to 2,000 mg doses, the study was concluded early based on achieving compelling pain reduction and opioid use reduction data with only 1,500 mg.

The preliminary summary study outcomes include:

1. Over 14 days, the cohort treated with 1,500 mg of ATX-101 took between half to two-thirds less opioids than a typical TKA patient, and 80% were off opioids at the end of that period relative to approximately 50% for the standard of care, according to published literature.
2. In the same cohort, ATX-101 significantly outperformed the standard of care throughout the 14-day period for both the duration and magnitude of effect, using proprietary data sets of pain scores from clinical trials after TKA surgery. In this study, ATX-101 kept patients’ post-surgical pain in the zero or mild range for at least 14 days, relative to the published standard of care that typically results in severe short-term pain followed by moderate pain lasting for weeks. The standard of care includes various repeatedly dosed medications, including opioids.
3. ATX-101 delivered highly predictable dose responses across all three cohorts. It showed a clear linear relationship through the 14-day period between dose and maximum systemic concentration, as well as between dose and pharmacokinetic area under the curve, which represents total exposure to drug (R2 > 0.98). Predictable dynamics of drug delivery are a necessary property for therapeutic products like ATX-101 to support confidence in dosing selection.
4. ATX-101 delivered meaningful continual dosing throughout the 14-day period studied. During the acute phase of 0-4 days, comparable levels of bupivacaine were delivered by ATX-101 as compared to competitor products in published TKA studies. According to published literature, all other approved approaches using bupivacaine in TKA are no longer detectable five days after administration, whereas ATX-101 showed meaningful systemic levels through 14 days.
5. ATX-101 was observed to be generally well-tolerated in the study and no serious adverse events related to the product were seen.

“These data suggest an exciting therapeutic profile very different from anything in the current surgical pain management toolkit. The standard of care struggles to adequately serve patients in settings like TKA, which typically involves significant short-term and longer-term pain across a lengthy recuperation period,” said David Dalury, M.D., clinical professor of orthopedic surgery at the University of Maryland School of Medicine and Chief of Orthopedics at the University of Maryland St. Joseph Medical Center. “In orthopedic surgery, we are looking for simple, non-opioid solutions with consistent outcomes beyond two to three days that help patients return to normal function faster, to support earlier discharges and reduced need for ongoing clinical management. ATX-101 has made a promising step towards these goals and I look forward to further clinical data.”

Beyond ATX-101, Allay has developed proof-of-concept of new implant variants, injectable formulations, formulations to permit patient self-dosing ‘on demand’ and formulations that incorporate a variety of small molecules and other local analgesics.

Allay Therapeutics was founded in 2017 by The Foundry incubator and Lightstone Ventures’ Singapore fund. Following the acquisition of polymer innovator Orchid Medical in 2018, the company initiated pre‑IND discussions with the FDA and in 2019 completed a $25 million Series B financing led by NEA, with additional participation by Lightstone Ventures and Brandon Capital Partners.

Allay intends to proceed into a Phase 2b study of ATX-101 in the United States in 2021 and pursue regulatory filings with the United States Food and Drug Administration to support the Phase 2b study and a future potential Phase 3 clinical study, with a targeted NDA submission in 2024.

About ATX-101: In development to treat pain following total knee replacement surgery

ATX-101 is a novel configuration of an approved, well-characterized, validated intracellular sodium ion channel blocker, bupivacaine, and a biopolymer that has been designed to provide weeks of pain relief following total knee arthroplasty (replacement), or TKA, a common orthopedic surgery. ATX-101 has a high density of drug within its small footprint to allow for ultra-sustained analgesia. It is placed at the end of standard surgery, in minutes, to deliver its analgesic effect over weeks before dissolving into water and carbon dioxide over a longer period.

Summary outcomes from a Phase 1b/2a clinical study of ATX-101 demonstrated sustained pain relief lasting at least two weeks, with significant outperformance of historical pain relief scores provided by other approaches following TKA. Across all clinical and preclinical studies, ATX-101 appears to be well-tolerated with minimal systemic exposure, with no serious adverse events.

TKA recuperation is currently managed with short-term products that offer only up to two or three days of pain relief and are highly variable in impact, and as a result are often supplemented with opioids. These current treatments do not adequately support the patient’s early ‘breakthrough pain’ period or subsequent rehabilitation. Where local anesthetics are used, they can involve complex procedures that are difficult to administer consistently and to the precise site of pain. The United States alone currently sees over one million TKAs annually with an annual growth rate of 20%, creating a strong need for non-opioid solutions to facilitate outpatient procedures and longer-term recuperation.
