About RTX
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.

About osteoarthritis
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. [3]

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. [4] Many patients will need joint replacement surgery.
