'''GT-20029''', also known as '''AR-PROTAC''', is an androgen receptor degradation enhancer which is under development for the treatment of androgenetic alopecia (male-pattern hair loss) and acne.<ref name="AdisInsight">{{cite web | title = GT 20029 | date = 28 September 2024 | website = AdisInsight | url = https://adisinsight.springer.com/drugs/800062165 | access-date = 2 October 2025 }}</ref><ref name="Synapse">{{cite web | title = Delving into the Latest Updates on GT-20029 with Synapse | date = 16 August 2025 | website = Synapse | url = https://synapse.patsnap.com/drug/42532833634043c9ba770ad3352e3a39 | access-date = 2 October 2025 }}</ref><ref name="Han_2022">{{cite journal | vauthors = Han X, Sun Y | title = Strategies for the discovery of oral PROTAC degraders aimed at cancer therapy | journal = Cell Reports Physical Science | volume = 3 | issue = 10 | article-number = 101062 | date = 2022 | doi = 10.1016/j.xcrp.2022.101062 | bibcode = 2022CRPS....301062H | doi-access = free | quote = Discovery of oral AR degrader GT20029 (undisclosed structures): Recently, Kintor Pharmaceutical Ltd. (Hong Kong Exchanges and Clearing Market [HKEX]: 9939) developed a topical AR degrader based on the PROTAC platform with development of an oral PROTAC drug (GT20029) targeting AR. The animal experiments showed that GT20029 is superior to other small molecule AR inhibitors. The company announced that the investigational new drug (IND) GT20029 for androgenetic alopecia and acne vulgaris indications was accepted by the National Medical Products Administration (NMPA) of China on February 2, 2021. With improved efficacy, GT20029 was reported to effectively avoids systemic exposure to mitigate the side effects of typical oral drugs. The time will tell how GT20029 performs in the clinical trials. }}</ref> It is used topically in gel form.<ref name="AdisInsight" /><ref name="SacedaCorralo_2023" />
