In fact, even on a global scale, medical experts with experience and qualifications similar to Art’s in the development of novel dermatological drugs are exceedingly rare. His joining will significantly enhance the efficiency and quality of Tecro’s clinical research on innovative drugs. It is reported that Art will be fully responsible for the clinical studies of Tecro’s hair regrowth project already underway in the United States, as well as the clinical development of upcoming projects targeting eczema, psoriasis, and lupus erythematosus. This appointment of the Chief Medical Officer (CMO) also signifies that Tecro will rapidly advance into clinical studies across multiple dermatological disease areas, gradually establishing a leading industry advantage in clinical development.
From the perspective of industry insiders, China’s pharmaceutical market has historically been dominated by generic drugs, with a scarcity of talent in clinical development. Even as innovation-driven drug R&D gains momentum today, talent across various stages remains heavily concentrated in the oncology sector, while clinical experts specializing in dermatology are exceedingly rare. Commenting on Dr. Art’s joining the company, Dr. Wang Zengquan, CEO of Tekelo, stated, “We are honored to have invited Dr. Art from the United States to join Tekelo. As our Chief Medical Officer (CMO), Dr. Art will provide significant impetus to the company’s new drug R&D efforts. The clinical development of novel dermatological therapies requires guidance from an expert like Dr. Art, who possesses profound professional expertise and strong capabilities in clinical research.”
Tecro also announced the establishment of its Scientific Advisory Board, comprising several distinguished internationally renowned scientists. In the future, the Scientific Advisory Board will serve as a think tank to guide the company’s drug R&D strategies, strategic directions, and decision-making. The inaugural members of Tecro’s Scientific Advisory Board include Professor Gary J. Fisher, Dr. John Mao, Dr. Art P. Bertolino, Professor Xiang Leihong, and Dr. Wang Zengquan. The establishment of the Scientific Advisory Board will safeguard the development of the company’s future R&D pipeline and clinical research directions, thereby empowering and accelerating its new drug development efforts.
Professor Gary J. Fisher is an internationally recognized leader in molecular dermatology and currently holds an endowed professorship in Dermatology at the University of Michigan Medical School.

Currently, clinical studies involving patients with hair loss are underway in the United States. The Phase I single ascending dose (SAD) trial is nearing completion, and the study will soon proceed to the multiple ascending dose (MAD) trial phase. TDM-105795 is expected to enter Phase II clinical trials in the second half of 2022.
In the field of inflammatory skin diseases, the company is focused on advancing the R&D of highly differentiated innovative small-molecule JAK inhibitors tailored to specific dermatological conditions. It has already established a robust intellectual property portfolio, with multiple series of compounds under simultaneous development for eczema, psoriasis, and lupus erythematosus.
Notably, preliminary efficacy results for the eczema program demonstrated that the candidate drug has a significant therapeutic advantage, with greater potency than marketed PDE4 inhibitors and comparable efficacy to glucocorticoids but without their adverse cutaneous side effects. The eczema program is expected to submit an Investigational New Drug (IND) application for Phase I clinical trials in the second quarter of 2022. The company’s new drug candidates for psoriasis and lupus erythematosus are also gradually entering the stage of submitting clinical trial applications.
