Remegen Stock Price, News & Analysis

RemeGen Co., Ltd. (REGMY) is a biopharmaceutical company in the biotechnology research and development industry. According to company disclosures, it focuses on discovering, developing, manufacturing, and commercializing novel biologic drugs with independent intellectual property rights. RemeGen is described as an innovative biopharmaceutical company headquartered in Yantai in China, with research and development centers and subsidiaries in Beijing, Shanghai, and California in the United States. Its shares are listed on the Main Board of The Stock Exchange of Hong Kong Limited and on the Shanghai Stock Exchange STAR Market, making it a dual-listed "A+H" company.

The company concentrates on critical therapeutic areas that include autoimmune diseases, oncology, and ophthalmology. Within these areas, RemeGen reports that it has successfully developed multiple biologic drugs with significant clinical value. Its pipeline and marketed products, as described in company news, include first-in-class and novel biologic agents targeting specific disease mechanisms in autoimmune and oncologic indications, as well as ophthalmic diseases.

Core Biologic Drugs and Therapeutic Focus

RemeGen highlights telitacicept (RC18) as a global first-in-class B‑lymphocyte stimulator (BLyS)/A proliferation‑inducing ligand (APRIL) dual‑target fusion protein drug. The company states that telitacicept is an injectable recombinant fusion protein that simultaneously inhibits the binding of BLyS and APRIL cytokines to their receptors on B cells. By doing so, it aims to prevent abnormal differentiation and maturation of B cells and to treat autoimmune diseases.

According to RemeGen, telitacicept has been approved in China for the treatment of systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), and generalized myasthenia gravis (gMG). Company communications further state that telitacicept is the world's first approved BLyS/APRIL dual‑targeting fusion protein drug for myasthenia gravis and that it has completed Phase III clinical studies in indications such as gMG and primary Sjögren's syndrome in China.

In oncology, RemeGen reports the development of disitamab vedotin (DV, brand name: 爱地希®), described as the first domestically approved HER2‑targeted antibody‑drug conjugate (ADC) in China. Company announcements describe DV as being evaluated in multiple Phase II and Phase III clinical trials as monotherapy and in combination with other agents such as PD‑1 inhibitors and chemotherapy. These studies target indications including locally advanced or metastatic gastric cancer, urothelial carcinoma, and muscle‑invasive bladder cancer.

In ophthalmology, RemeGen highlights RC28‑E, a VEGF/FGF dual‑target fusion protein drug for ocular neovascular diseases. The company states that RC28‑E is being evaluated in indications such as diabetic macular edema (DME) and wet age‑related macular degeneration (wAMD), and that it has entered into an exclusive licensing agreement with Santen Pharmaceutical's China subsidiary for development, manufacturing, and commercialization of RC28‑E in specified Asian territories, while RemeGen retains exclusive rights outside those regions.

Research and Development Activities

RemeGen emphasizes a research‑driven model focused on biologic drugs with novel mechanisms of action. The company reports using internal technology platforms to design and develop fusion proteins and antibody‑based therapeutics. In addition to telitacicept and disitamab vedotin, RemeGen has disclosed the development of RC148, a bispecific antibody targeting PD‑1 and VEGF. RC148 is described as an innovative molecule developed using the company's bispecific antibody technology platform and is being investigated in clinical trials for multiple advanced malignant solid tumors, including monotherapy and combination therapy approaches.

Company news indicates that RemeGen participates actively in international scientific and medical meetings, presenting clinical data at conferences such as the American Academy of Neurology (AAN), American Society of Clinical Oncology (ASCO), American Society of Clinical Oncology Genitourinary Cancers Symposium (ASCO GU), Association for Research in Vision and Ophthalmology (ARVO), and the American Association of Neuromuscular & Electrodiagnostic Medicine (AANEM). These presentations cover Phase II and Phase III trial results across its autoimmune, oncology, and ophthalmology pipelines.

Regulatory Milestones and Designations

According to company announcements, telitacicept has received multiple regulatory recognitions. In China, the myasthenia gravis indication for telitacicept was included in breakthrough therapy and priority review categories by the National Medical Products Administration (NMPA). Internationally, RemeGen reports that telitacicept has received orphan drug designation and fast track designation from the U.S. Food and Drug Administration (FDA) for myasthenia gravis, and orphan drug designation from the European Medicines Agency (EMA) for myasthenia gravis. The company also notes that the Sjögren's syndrome indication for telitacicept has been granted Fast Track designation by the U.S. FDA and approval to initiate a global multicenter Phase III clinical trial.

In oncology, disitamab vedotin has been the subject of multiple clinical studies that RemeGen reports as reaching key endpoints, including Phase 3 trials in HER2‑expressing locally advanced or metastatic urothelial carcinoma. In bladder cancer, the company has disclosed Phase II data for disitamab vedotin plus immunotherapy as a perioperative regimen for muscle‑invasive bladder cancer, reporting high pathological complete response rates and what it describes as manageable safety profiles.

In ophthalmology, RemeGen has reported Phase II clinical trial results for RC28‑E in diabetic macular edema, noting improvements in visual acuity and retinal thickness measures, along with tolerability in patients. The company has also indicated that Phase III clinical trials for RC28‑E in wAMD and DME have been initiated in China.

Commercialization and Partnerships

RemeGen states that it has established a commercialization system encompassing both production and sales, supporting the commercial launch of its approved biologic drugs in domestic and some international markets. The company describes itself as having successfully initiated commercial transformation based on its marketed products.

In addition to internal commercialization, RemeGen engages in licensing and collaboration agreements. For RC28‑E, it has granted Santen's China subsidiary exclusive rights in Greater China and several Asian countries, while retaining rights elsewhere. For telitacicept, RemeGen has disclosed an out‑licensing arrangement with Vor Bio, under which Vor Bio is advancing a global multicenter Phase III clinical trial for generalized myasthenia gravis, with patient recruitment reported in regions including the United States, Europe, South America, and Asia‑Pacific.

Clinical and Scientific Positioning

Across its portfolio, RemeGen emphasizes first‑in‑class or novel mechanisms, particularly in targeting B‑cell biology and HER2‑expressing tumors. Company communications describe telitacicept as the world's first BLyS/APRIL dual‑target fusion protein drug and disitamab vedotin as the first domestic HER2‑targeted ADC in China. The company highlights clinical data that it characterizes as demonstrating clinically meaningful efficacy and safety profiles in multiple indications, and notes that its work has been recognized in guidelines and expert consensus documents in China for conditions such as Sjögren's syndrome.

RemeGen's activities, as described in its news releases, position it within the professional, scientific, and technical services sector, with a focus on biotechnology research and development and the translation of biologic drug candidates into approved therapies for autoimmune diseases, cancers, and ophthalmic conditions.
