Yes.

(2026-03-18) ''In terms of efficacy: compared to the placebo group, both 1.0% BID (i.e. twice a day) group and 0.5% BID group demonstrated statistically significant therapeutic efficacy and clinical significance. The target area non-vellus hair counts (“TAHC”) of the 1.0% BID group showed an increase of 15.33 hairs/cm 2 from baseline, the TAHC of the 0.5% BID group showed an increase of 14.46 hairs/cm2 from baseline, and the TAHC of the placebo group showed an increase of 4.68 hairs/cm2 from baseline. The TAHC of the 1.0% BID group showed an increase of 10.65 hairs/cm2 from the placebo group, with statistically significant results (P<0.0001). The TAHC of the 0.5% BID group showed an increase of 9.78 hairs/cm2 from the placebo group, with statistically significant results (P<0.0001).''

''Based on results of previous clinical trials, the Company plans to communicate and initiate the NDA submission for KX-826 1.0% to the drug regulatory authorities in the PRC in the near term.''

''The Company will strive to position KX-826 as the first-in-class drug approved by regulatory authorities for the treatment of Androgenetic Alopecia in China and globally. Upon approval, KX-826 is expected to fill the current clinical gap for new drugs in Androgenetic Alopecia treatment and break the nearly 40-year treatment paradigm that has relied solely on minoxidil and finasteride.'' https://en.kintor.com.cn/news_details/22.html

It means that the efficacy of the medicine begins to wane from the sixth month of use.
It is critical to distinguish between a drug losing all efficacy and a drug peaking and stabilising.

According to top-line data from Kintor's year-long study, patients using 0.5% pyrilutamide twice daily still experienced significant increases in target area hair count (TAHC) and hair width (TAHW) at 52 weeks compared to where they started (baseline). https://en.kintor.com.cn/news_details/9.html

This data looks impressive at first glance, but in reality, it's not as good as min or finasteride.

Unlike oral finasteride or dutasteride, which reduce systemic DHT levels, pyrilutamide is designed to work locally with a different mechanism of action, so is a good option for those that can't or won't take finasteride or dutasteride.

Pyrilutamide 1.0% BID (twice daily): +15.33 hairs/cm² from baseline, which was +10.65 hairs/cm² over placebo. Pyrilutamide 0.5% BID (twice daily): +14.46 hairs/cm² from baseline, which was +9.78 hairs/cm² over placebo.

The placebo-adjusted gain looks competitive with established therapies. However, cross-trial comparisons should be made cautiously: populations, endpoints, baseline severity, counting methods, and timepoints differ across trials.

An open-label clinical observational trial found that combining pyrilutamide (0.5% BID) with minoxidil (5% BID) is superior to minoxidil monotherapy. The combination group showed a mean target area non-vellus hair count (TAHC) increase of +30.54 hairs/cm² from baseline. The combination exceeded minoxidil monotherapy by 10.29 hairs/cm², a statistically significant difference. A higher proportion of patients in the combination group achieved improvements of ≥ 20 and ≥ 40 hairs/cm², alongside numerical improvements in hair growth assessment (HGA) scores. Both groups showed comparable, favourable safety profiles and good tolerability. No unexpected adverse events or drug-related sexual dysfunction reactions were reported. https://en.kintor.com.cn/news_details/10.html
