TLC Announces TLC599 Agreement with Endo
SOUTH SAN FRANCISCO, Calif. and TAIPEI, Taiwan, June 13, 2022 (GLOBE NEWSWIRE) -- TLC BioSciences (TLC), a clinical-stage specialty pharmaceutical company developing novel nanomedicines to target areas of unmet medical need, today announced that it has entered a commercialization agreement with Endo International plc (NASDAQ:ENDP) for rights in the United States to TLC599, a proprietary BioSeizer® sustained release injectable in Phase 3 development for the treatment of osteoarthritis pain.
Under the terms of the agreement, signed with Endo's subsidiary Endo Ventures Limited (EVL), TLC will primarily be responsible for the development of the product and EVL will primarily be responsible for obtaining regulatory approval and commercialization of the product in the United States. Upon receipt of regulatory approval, Endo will have exclusive rights to manufacture, market, sell and distribute the product in the United States. TLC will receive an upfront payment of $30 million and will be eligible to receive up to an additional $110 million based on the achievement of certain development, regulatory, and manufacturing milestones related to the initial indication for the treatment of osteoarthritis knee pain. TLC will be eligible to receive payments based on the achievement of certain commercial milestones and royalties based on the product's net sales in the United States. Additionally, TLC will be eligible to receive certain milestone payments for potential future indications.
"We are thrilled to be partnering with Endo once again," said George Yeh, President of TLC. "Endo's proven capabilities in the orthopedic space complement TLC's expertise in developing novel nanomedicines, and together, we hope to deliver life-enhancing therapies to meet an unmet need with a large patient base."
"TLC599 is fully aligned with our commitment to providing differentiated nonsurgical options to healthcare providers and their appropriate patients," said Patrick Barry, Executive Vice President and President, Global Commercial Operations at Endo. "This investigational product is highly synergistic with our existing orthopedic commercial capabilities and complements our current on-market and in-development orthopedic-focused opportunities."
"We are pleased to be adding another TLC product to Endo's portfolio," said Blaise Coleman, President and Chief Executive Officer at Endo. "We see tremendous opportunity in TLC599 to potentially address an unmet medical need in patients with osteoarthritis arthritis knee pain. If approved, we expect to launch this differentiated branded product in 2025."
About Osteoarthritis
OA is the most common form of arthritis, affecting an estimated 32.5 million adults in the United States, according to the Centers for Disease Control and Prevention.1 Although OA can occur in any joints, it occurs most frequently in the hands, hips and knees. With OA, joint cartilage becomes worn and breaks down, and as a result, the bone surfaces can grind together and eventually begin to change. Common symptoms of OA include pain, stiffness and swelling, and they can worsen over time. In some cases, OA also can cause reduced function and disability. There is no cure for OA; however, symptom management options include behavior modification, drug therapy (oral, topical and injections within the joint) and knee replacement surgery.
About TLC599
TLC 599 is an extended and controlled release liposomal formulated dexamethasone for chronic knee osteoarthritis (OA) pain. Single and repeated doses of current intraarticular anti-inflammatory treatments for OA have potentially toxic side effects and may lead to the destruction of cartilage filler proteins. Preclinical toxicity studies showed no marked cartilage damage after single and multiple doses of TLC599 when compared to current treatments. In a Phase II clinical trial, a single injection of TLC599 resulted in statistically significant and clinically meaningful improvement in WOMAC Pain and Function Subscales, and VAS Pain scores over placebo at 12, 16 and 24 weeks. Over half of the patients in the TLC599 group had a durable response, maintaining at least 30% pain reduction in both WOMAC and VAS pain scores at all visits through the 24 weeks. No serious or unexpected treatment related adverse events were reported, and most of the treatment related adverse events were mild to moderate in severity. EXCELLENCE, a pivotal Phase III clinical trial to evaluate the efficacy and safety of both single and repeated doses of TLC599, is nearing completion, with the last patient's last visit having taken place in January 2022. The compound may be investigated in the future for additional potential indications.
