Investigative medicine is being developed to provide patients with pain associated with osteoarthritis with a well-tolerated, non-opioid therapy alternative that aims to relieve chronic pain and improve the functioning of affected joints.
RTX is a highly potent transient receptor potential vanilla 1 (TRPV1) agonist with a well-proven mechanism of action. Phase III trials will investigate the efficacy, safety, and tolerability of RTX in patients with osteoarthritis of the knee. The trials will begin in 2022 and are designed to meet marketing approval requirements in the EU, US and Japan.
“Worldwide, more than 300 million patients suffer from osteoarthritis . For many of them, the available treatment options are not enough and they may experience serious symptoms, including pain at one time, “said Granenthal, MD, chief scientific officer at Jane Adams.” Can benefit patients. The agreement provides Gruenthal with headroom for further investment in the implementation of its growth strategy and the progress of a promising pipeline to the clinic. “
Under the terms of the agreement, NovaQuest will repay Grünenthal’s investment in RTX’s Clinical Phase III program and share clinical development and approval risks with Grünenthal. In the case of successful development and marketing approvals, NovaQuest receives one-time payments or milestones and revenue-based payments during commercialization.
Ryan Utten, Managing Director of NovaQuest, said, “NovaQuest is interested in partnering with a leading company in the field of pain therapeutics to develop RTX, a promising asset that could enter the market by 2025.” “We are confident that Grunenthal has the right capabilities to position RTX in the global osteoarthritis market and take full advantage of the resources available to patients in need.”
Grünenthal holds global rights for RTX and is in a good position to tap the global osteoarthritis market, which is expected to show strong growth from $ 7.3 billion in 2020 to about .0 11.0 billion in 2025. , Forming a large global trade opportunity. Just to indicate osteoarthritis of the knee, Grenthal estimates the potential maximum sales in Europe and the United States will be above € 1 billion. In addition, Grünenthal wants to explore the potential of RTX for the treatment of osteoarthritis-related pain in extra joints outside the knee.

RTX is an intra-articular injection of resinferatoxin designed to treat pain in patients with advanced knee osteoarthritis. Resiniferatoxin is a highly potent transient receptor potential vanilloid 1 (TRPV1) agonist. Its administration can reverse TRPV1-releasing nociceptors. This can relieve chronic pain. Preliminary data show a long-lasting and significant analgesic effect and effective improvement over placebo, as well as an optimal safety profile.
Osteoarthritis (OA) can be defined as a group of distinct but overlapping diseases. They may have different etiologies, but similar biological, morphological, and clinical outcomes that affect the articular cartilage, subchondral bone, ligaments, joint capsule, synovial membrane, and periarticular muscle. OA is the most common joint disease in people 65 years of age or older. Its etiology is not fully understood, although there are several related factors, including female sex, genetics, metabolism, and excessive mechanical stress. OA diagnosis is based primarily on clinical history and physical examination. The main radiographic features of OA are high pressure, focal / non-uniform narrowing of the joint space in the case of subchondral cysts, subchondral sclerosis, and osteophytes. 
Osteoarthritis is a disease of the joint where the joint tissue breaks down over time. Common symptoms of osteoarthritis include joint pain, stiffness and swelling, as well as changes in joint movement and a feeling of loosening or dislocation of the joint. The most affected joints are the hands, knees, buttocks, neck and lower back. Treatment for osteoarthritis usually includes exercise, maintaining a healthy weight, wearing braces to help maintain stability, and taking medication if prescribed.  Many patients will need joint replacement surgery.
