Disitamab vedotin (RC48) is a novel anti-HER2 antibody-drug conjugate (ADC) which is currently across various solid tumor types. RC48 is characterized by a higher affinity to HER2 compared to standard of care and superior anti-tumor activity. It was the first domestically-developed ADC in China approved by the CDE for clinical development in China.
RemeGen is implementing a differentiated development and commercial strategies for disitamab vedotin for prevalent HER2 expressing cancers lacking effective treatment methods. The indications of disitamab vedotin include HER2 expressing (IHC 1+ or above) cancer, such as gastric cancer (GC) and urothelial carcinoma (UC) (currently in registered clinical trials in China), and HER2 low-expressing cancer (IHC 2+ / FISH- or IHC 1+), such as HER2 low-expressing breast cancer (currently in registered clinical trial in China).
Telitacicept (RC18) is a potentially novel first-in-class TACI-Fc fusion protein for the treatment of B cell-mediated autoimmune diseases. It targets and neutralizes two cell-signaling ligands, BLyS and APRIL, to down modulate the overexpression of B-cells implicated in autoimmune diseases. We are carrying out a broad clinical development program spanning 7 indications for telitacicept targeting a variety of B cell-mediated autoimmune diseases with unmet or underserved medical needs. Systemic lupus erythematosus (SLE) is the lead indication of Telitacicept.
In addition to SLE, we are actively developing telitacicept for six other B cell-mediated autoimmune diseases in late-stage clinical trials in China, including two registrational clinical studies in neuromyelitis optica spectrum disorder (NMOSD) and rheumatoid arthritis (RA); two Phase II studies in IgA nephropathy (IgAN) and Sjögren’s syndrome (SS) (indications with high prevalence but lacking efficacious treatments); and two Phase II studies in hard-to-treat rare diseases, including multiple sclerosis (MS) and myasthenia gravis (MG).
RC28 is a potential first-in-class VEGF/FGF dual-targeting fusion protein for the treatment of eye diseases. Compared to single-target VEGF inhibitors, RC28 has the potential to more effectively inhibit the abnormal blood vessel growth implicated in various eye diseases through both VEGF and FGF pathways, potentially allowing for a better dosing profile. RC28 has completed a Phase I dose escalation study in patients with wet age-related macular degeneration (wet AMD) in China.
