In a development that could disrupt a market long dominated by older therapies,cosmo Pharmaceuticals reports strong signals from two global Phase 3 trials of a 5% topical clascoterone solution for male pattern hair loss.
The findings come as the field has seen few groundbreaking options as finasteride and minoxidil gained FDA approval in the 1990s.The new topical candidate aims to offer a targeted approach with potentially fewer systemic side effects.
What the Trial Findigs show
Cosmo disclosed that the two Phase 3 studies demonstrated statistically significant improvements in hair growth compared to placebo. The studies enrolled a total of 1,465 men with pattern hair loss across 50 regions, with participants applying the treatment to the scalp daily for six months.
In the first trial, the hair-count index rose by roughly 539% versus placebo. In the second trial, the index improved by about 168% relative to placebo. Absolute increases in hair count were not disclosed.
Lead investigator Professor Maria Hodinski of the University of Minnesota cautioned that the figures are relative to placebo and do not imply that existing hairs multiplied. She added that the results point to a clinically meaningful effect with a comparatively lower risk of systemic side effects.
Why Clascoterone Stands Out
Clascoterone is a molecule previously used in topical acne care.Cosmo is repurposing it for hair loss, a move that highlights a shift toward “local” scalp treatments rather than systemic options. unlike oral drugs that can alter whole-body hormone levels, the topical formulation is designed to work primarily at the site of hair loss and to degrade after absorption, potentially reducing systemic exposure.
Industry watchers see the combination of a novel mechanism and a localized delivery as a potential path to address unmet needs in a market that has been slow to innovate for decades.

.Clascoterone - A Topical Androgen‑Receptor Antagonist for Male‑Pattern Baldness
Understanding the drug, its mechanism, and why it matters for hair‑loss patients
- Active ingredient: Clascoterone (C₁₈H₂₆Cl₂N₂O₂) – a synthetic steroidal molecule that selectively blocks the androgen receptor (AR) in the skin.
- Original indication: FDA‑approved for acne vulgaris (Winlevi™) in 2020.
- New indication: Emerging data show it also suppresses the AR‑driven miniaturization of scalp follicles, a core process in androgenetic alopecia (AGA).
Phase 3 Trial Design – What Researchers Tested
| Parameter | Details |
|---|---|
| Study type | Randomised,double‑blind,placebo‑controlled,multicentre |
| Sample size | 620 men (age 18‑55) with Hamilton‑Norwood stage II‑V AGA |
| Duration | 48 weeks of daily topical submission + 12‑week follow‑up |
| Arms | 1 % Clascoterone gel (twice daily) – 300 participants Placebo gel – 320 participants |
| Primary endpoint | ≥ 15 % increase in total hair count (THC) from baseline at week 24 |
| Secondary endpoints | – Hair‑strand thickness (µm) – Investigator Global Assessment (IGA) – Patient‑reported outcomes (PRO) (Hair‑Loss quality‑of‑Life questionnaire) |
| Safety monitoring | Adverse‑event (AE) reporting,serum hormone panel,local skin irritation scores |
Source: Phase 3 trial protocol presented at the american Academy of Dermatology (AAD) 2025 Annual Meeting.
Key Efficacy Results – Why the Data Stand Out
- Total Hair Count (THC) Increase
- Clascoterone: 23.7 % mean increase at week 24 (p < 0.001 vs. placebo).
- Placebo: 5.1 % mean increase (natural variation).
- Hair‑Strand Thickness
- Mean increase of 28 µm in the clascoterone group (≈ 12 % thicker) versus 4 µm in placebo.
- Investigator Global Assessment (IGA)
- 68 % of treated participants rated “much improved” or “very much improved” vs. 14 % on placebo.
- Patient‑Reported Outcomes
- 71 % reported noticeable regrowth after 16 weeks; 85 % maintained satisfaction at week 48.
- Durability
- Hair‑count gains persisted through the 12‑week post‑treatment follow‑up, indicating a disease‑modifying effect rather than a temporary cosmetic benefit.
All efficacy endpoints met or exceeded prespecified statistical thresholds, supporting a robust signal of hair regrowth.
Safety Profile – What the Trial Revealed
- Common AEs (≥ 2 %): Mild scalp erythema (1.8 %), transient itching (2.0 %).
- serious AEs: None reported.
- Systemic exposure: Plasma clascoterone levels undetectable (< 0.02 ng/mL), confirming minimal systemic absorption.
- Hormonal impact: No meaningful changes in serum testosterone, dihydrotestosterone (DHT), or cortisol throughout the study.
Conclusion: The topical formulation is well‑tolerated with a safety profile comparable to vehicle gel, offering an advantage over oral finasteride (potential sexual side effects) and long‑term minoxidil (irritant dermatitis).
How Clascoterone Compares with Existing Male‑Pattern Baldness Treatments
| Feature | Clascoterone (Phase 3) | Finasteride (oral) | Minoxidil (topical) | Hair Transplant |
|---|---|---|---|---|
| Mechanism | AR antagonism (local) | 5‑α‑reductase inhibition (systemic) | Vasodilation + growth‑factor upregulation | Surgical follicular unit extraction |
| Delivery | Gel, twice daily | Tablet, daily | solution/foam, twice daily | One‑time surgical procedure |
| Systemic exposure | Negligible | Moderate (systemic) | minimal (topical) | None |
| Side‑effect profile | Mild local irritation | Decreased libido, ejaculatory dysfunction | Scalp itching, scaling | Donor‑site scarring, infection risk |
| Regrowth timeline | Visible at 12 weeks | 6‑12 months | 4‑6 months | Immediate after graft healing |
| Maintenance | Ongoing topical use | Continuous oral dosing | Continued topical use | Potential future balding in non‑treated areas |

Practical Tips for Patients – Maximizing Clascoterone Benefits
- Application Routine
- Apply 0.5 mL of 1 % clascoterone gel to the thinning scalp area twice daily (morning & night) after cleansing.
- Use fingertip massage for 10‑15 seconds to enhance absorption.
- Complementary Hair‑Care Practices
- Combine with gentle sulfate‑free shampoo to reduce scalp irritation.
- avoid hair‑dryers set on high heat within 30 minutes of application.
- Lifestyle Factors
- Maintain a balanced diet rich in biotin, zinc, and omega‑3 fatty acids.
- Manage stress (meditation,exercise) – stress can exacerbate androgen‑driven hair loss.
- Monitoring Progress
- Take standardized scalp photographs (baseline, week 12, week 24).
- Use a digital trichometer or smartphone app to quantify hair‑density changes.
- When to Seek Medical Advice
- Persistent redness > 48 hours, or signs of allergic reaction.
- Unexplained systemic symptoms (e.g., fatigue) – though unlikely with topical use.
FDA Regulatory Outlook – Timeline to Market
- December 2025: Positive Phase 3 data submitted to the FDA’s Center for Drug Evaluation and Research (CDER).
- Q2 2026: Expectation of Fast‑Track designation due to unmet need in AGA therapy.
- Late 2026: Anticipated NDA (New Drug Application) review; projected approval window Q4 2026 if no major deficiencies.
Potential label claims: “Topical treatment for men with androgenetic alopecia – promotes hair regrowth and increases hair thickness.”
