Veradermics.

Veradermics (US) is working on a new extended-release oral Minoxidil tablet to treat androgenetic alopecia (AGA). The product is called VDPHL (as well as VDPHL01) and is currently in Phase 3 clinical trials. The top half of this post contains new updates in reverse chronological order. Also see my past posts on immediate-release low-dose oral Minoxidil and sublingual Minoxidil.

Veradermics Raises $150 million in Series C Financing

Yesterday, we heard that Pelage Pharmaceuticals (US) raised a massive $120 million in Series B Financing. In 2026, they plan to begin Phase 3 trials for their hair growth product PP405.

Today, we have news that Veradermics has raised an even larger $150 million in an oversubscribed Series C Financing. And this is after they raised $75 million in 2024 from Series B Financing. Such numbers are unheard of in the hair loss world. Veradermics is already conducting multiple Phase 3 trials for their hair growth product VDPHL.

For context, in 2021, the esteemed RIKEN and Dr. Takashi Tsuji of Japan were finding it difficult to raise $5 million and even asked me to help them with the goal. And in 2025, Yunce Biotech (China) is finding it tough to raise just $2 million to move forward with their hair cloning work. See the most recent comments from reader “Jan Miedza” in that Yunce post. And in late 2024, the much hyped Stemson Therapeutics (US) folded because it could not raise sufficient funds. Many other hair loss companies that I have discussed on this site in the past folded due to lack of funds to proceed with tedious clinical trials and approval processes.

In the earlier mentioned press release from Veradermics, they do not mention any other ingredient besides extended-release oral Minoxidil in this VDPHL01 tablet. The do provide some great before and after hair growth photos from their Phase 2 trials:

Early Study Finds Extended-Release Minoxidil Grows More Hair

An optimistic summary of the results from the 20-person Phase 2 trial of VDPHL01, with the volunteers taking 8.5 mg VDPHL01 twice daily for 4 months. In the control groups, 33 patients received 5 mg immediate-release oral minoxidil once daily for 6 months; and 34 patients received 1 mL of 5% topical minoxidil solution twice daily for 6 months. Investigator Global Assessment (IGA) was the primary outcome that was measured, and the IGA ratings were made by blinded investigators.

The summary contains an interesting quote from Dr. Jerry Shapiro (who it is mentioned has a financial relationship with Veradermics):

“A longer time to sulfate is what we want, so if we keep the drug in the blood longer, there is greater sulfation and more activity.

Make sure to read my past post on Minoxidil sulfotransferase boosters and why Minoxidil requires sulfation in order to grow your hair.

Also of note, VDPHL:

“Offers an opportunity to maintain drug levels above those needed for therapeutic effect, but below those associated with cardiac adverse events.”

Veradermics Extended Release Minoxidil for Hair Loss: Superior to Topical and Oral Minoxidil

Veradermics presented its smaller 20-person Phase 2 trial results at this month’s EADV Congress in Paris. A post about this on Instagram is causing some excitement. It has two slides in there, and I will paste the main points below:

  • The doctor Congress attendee who made the Instagram post states that “Extended release oral minoxidil has superior increase in hair density compared to topical minoxidil and oral minoxidil. Phase 3 trials are underway.” So this confirms that VDPHL is extended release oral Minoxidil, even though Veradermics’ pipeline page still does not declare the key ingredient.
  • 82% of VDPHL01 patients achieved moderate to great improvement versus just 20% of topical Minoxidil or low-dose oral Minoxidil users.
  • There is superior efficacy (3.5 times higher IGA scores) in a shorter time frame (4 months versus 6 months) compared to “competitors”).

Veradermics Phase 2/3 Clinical Trial Enrollment Link

Veradermics Phase 2/3 US clinical trial enrollment link is live. Their 40 plus locations are pretty widely spread across the country. Please note that we are not certain of the active ingredient(s) in this tablet. From the company’s patent, I previously guessed that it is an extended release oral Minoxidil, plus hopefully some other surprises (see bottom of this post). But it could end up being something totally different too.

The study involves 13 visits to a clinic over the course of 12 months. Participants will either get the new treatment or be part of the placebo group (that will still also get a tablet).

Update: December 11, 2024

Veradermics Raises $75 Million for Phase 2/3 Trials

Veradermics just raised $75 million in Series B financing (h/t “meko”). They have also initiated a Phase 2/3 trial for their lead candidate VDPHL01 for the treatment of androgenetic alopecia (AGA). The trial will enroll 480 patients across 44 sites in the US. Note that Veradermics also has an ongoing 20-patient Phase 2 trial for VDPHL. The company plans to report topline data from that Phase 2 study in the first half of 2025.

Veradermics VDPHL Tablet: Phase 2 Trials Begin

Veradermics is a US-based startup that is working on a new tablet to treat androgenetic alopecia (AGA). They just started Phase 2 clinical trials for VDPHL01 in male subjects with AGA. Only 20 patients are enrolled, and the completion date is listed as August 1, 2025. The trial will take place at Therapeutic Research’s center in San Diego, California. Note that VDPHL likely stands for Veradermics Pattern Hair Loss.

The tablet does not impact hormone levels as do dihydrotestosterone (DHT) inhibitors finasteride and dutasteride. Thus avoiding potential side effects. Veradermics’ CEO is a young dermatologist named Reid Waldman.

Modified Release or Extended Release Oral Minoxidil

The mechanism of action (MOA) and key ingredient(s) in this tablet are both confidential. However, when I searched through the company’s patent, it seems like the drug candidate will be a “modified release” oral minoxidil tablet. In the patent, they use the term “extended release (ER)”. Note that they do not use the term “sublingual minoxidil” anywhere in the patent.

Other Potential Ingredients in VDPHL

In the patent, they also have a massive list of 191 claims. Within that section, all of the following drugs are listed 11 times each:

  • Setipiprant (11 times).
  • Valproic acid (11 times).
  • Cetirizine (11 times).
  • Medrogestone (11 times).

For long time readers of this blog, setipiprant (and Kythera) will ring a bell. It caused so much excitement a decade ago. I cannot believe that the very optimistic 9-yr old audio interview with Kythera’s CEO is still online. Setipiprant is an oral antagonist to the prostaglandin D2 (PGD2) receptor.

I covered valproic acid and hair growth in detail in the past. Follica also has a patent that covers valproic acid and hair regrowth. Valproic acid activates the Wnt/β-catenin signaling pathway.

Cetirizine is a PGD2 inhibitor that has been shown to benefit hair growth even when used topically.

I have never covered medrogestone on this site before. Per Wikipedia, it is a progestin that is an agonist of the progesterone receptor and a weak anti-androgen. Progesterone is a female sex hormone that has beneficial properties towards hair growth.

Pelage Pharmaceuticals Phase 3 Trials for PP405 in 2026

I originally wrote this post on Pelage Pharmaceuticals and its PP405 hair growth product in 2023. For all of the older updates, scroll till the end of this page. Also check out my 2017 post on Pelage founder and president Dr. William Lowry’s work.

Update: October 15, 2025

Pelage Raises $120 Million. Phase 3 Trials in 2026.

In an insane development, Pelage just raised $120 million in Series B Financing. The round was co-led by ARCH Venture Partners and GV (Google Ventures), with participation from a few existing investors. This amount might be a record in the hair loss world. No wonder this post has over 900 comments, an all-time high for this site.

“The financing will support the continued advancement of Pelage’s lead program, PP405, a topical small molecule designed to reactivate dormant hair follicle stem cells, offering a potential first-in-class approach for both men and women experiencing hair loss.”

Pelage Pharmaceuticals

I previously wrote about Pelage Pharmaceuticals in my 2019 post related to the research of its President and co-founder Dr. William Lowry. The other co-founders are Dr. Heather Christofk and Michael Jung. I also covered the findings of Dr. Lowry and Dr. Christofk’s UCLA team in a 2017 post.

These UCLA researchers discovered two topical compounds (RCGD423) and (UK5099) that regrew hair in mice via different mechanisms. Both drugs involve an increase in lactate production. This in turn activates hair follicle stem cells and leads to increased and quicker hair growth.

Dr. Lowry’s patent can be found here. Patent and technology rights to both topical drugs have been exclusively licensed to Pelage Pharmaceuticals by UCLA.

RCGD423

RCGD423 activates the JAK-STAT signaling pathway, which in turn leads to an increase in lactate production. This extra lactate activates hair follicle stem cells and results in quicker hair growth. The main 2017 study on RCGD423, lactate dehydrogenase activity and hair follicle stem cell activation can be read here. I also covered it in my earlier linked posts related to the work of Pelage co-founders Dr. William Lowry and Dr. Heather Christofk.

UK5099

UK5099, blocks pyruvate (a glucose metabolite) from entering cell mitochondria. This also results in an increase in lactate production in the hair follicle stem cells, and therefore accelerates hair growth. There is a 2015 study from China related to the application of mitochondrial pyruvate carrier blocker UK5099 and its effects on prostate cancer cells.

Pelage Announces Positive Results of Phase 2a Trials for Hair Loss Drug PP405

Google Ventures (GV) backed Pelage Pharmaceuticals (US) just announced positive Phase 2a clinical trial results for PP405, its novel hair growth drug. The trial entails 78 men and women with androgenetic alopecia. Key quote:

“PP405 induced new hair growth from follicles where no hair was previously present — offering early validation of its regenerative potential.”

Note that the trial participants just had 4 weeks of treatment. At another 4 weeks after the completion of this treatment (“in men with a higher degree of hair loss”), 31% of those treated with PP405 exhibited a greater than 20% increase in hair density. In comparison, 0% of patients in the placebo group responded favorably. These results are incredibly rapid in comparison to existing treatments.

Pelage expects to begin Phase 3 trials in 2026. They will likely have no issues with fundraising.

Update: August 13, 2024

Pelage Pharmaceuticals (US) just announced that the first patients have been dosed in its Phase 2a clinical trial evaluating the safety and efficacy of PP405. This drug is a novel topical small molecule for the treatment of androgenetic alopecia. The company is enrolling 60 men and women in the clinical study. PP405 addresses the metabolic processes that regulate activation of hair follicle stem cells.

Also of significance, Pelage raised $14 million in Series A-1 financing that was led by Google Ventures (GV). This follows an initial $16.75 million Series A financing round in February 2024 (see bottom of this post). The Series A-1 is a result of positive Phase 1 data that demonstrated proof of mechanism and target engagement in patients with AGA.

Update: July 20, 2024

We now have more details on the Phase 2 trials for PP405. Including a short survey to determine eligibility. All 6 US states that I mentioned in the last update are now recruiting volunteers (with Texas having two locations). You have to be between the ages of 18-55, and once-a-week visits will be required for 16 weeks. The product comes in the form of a topical gel. Pelage Pharmaceuticals also has an update with the above link on its home page.

Update: June 12, 2024

Pelage Pharmaceuticals’ Phase 2 clinical trials of PP405 officially started on June 5, 2024. They are currently recruiting volunteers in Indiana, Minnesota, Texas and Utah. Still to come are California and Virginia. The primary completion date is December 2024, and the study completion date is February 2025. PP405 is an inhibitor of mitochondrial pyruvate carrier (MPC).

Update: May 6, 2024

Pelage Pharmaceuticals Phase 2 Clinical Trials for PP405 Start in June 2024

Yesterday, a reader e-mailed a new link on Pelage Pharmaceuticals’ Phase 2 clinical trials for its PP405 inhibitor of mitochondrial pyruvate carrier (MPC). The Phase 2 trials are set to begin in June 2024 and will involve 60 participants. Half of these will take a PP405 0.05% topical gel once per day, and the other half will get a placebo vehicle daily gel. The study primary completion date is December 2024, and actual completion date is February 2025.

Recruitment will likely start soon, and I assume it will be in the US based on the listed contact person and phone number. The contact e-mail is listed as clinicaltrials@pelagepharma.com. Please DO NOT call them now as the recruitment has not yet commenced and they might get annoyed.

If you are between the ages of 18-55 and have androgenetic alopecia, you can participate. However, the inclusion criteria for men and women is specific:

  • Males must have an AGA modified Norwood-Hamilton Classification score of Type III vertex, Type IV or Type V.
  • Females must have a Savin classification score of I-2, I-3 or I-4.

Positive PP405 Phase 1 Clinical Trial Results

Earlier today, Pelage Pharmaceuticals gave a positive update on its novel small molecule PP405. Full summary can be read here. In Phase 1 clinical trials, PP405 reactivated dormant hair follicle stem cells and triggered hair growth. The company’s presentation was made by Dr. Christina Weng and titled: “Inhibition of pyruvate oxidation activates human hair follicle stem cells ex vivo”. Pelage will begin its multi-center Phase 2a trial of PP405 in mid-2024. It will recruit both men and women with androgenetic alopecia.

Their description of this unique hair growth molecule is as follows:

“PP405 is a potent topical mitochondrial pyruvate carrier (MPC) inhibitor that acts on the cellular metabolic pathway to upregulate lactate dehydrogenase (LDH).”

Stem cells are particularly sensitive to LDH, so this results in their activation and subsequent hair growth. PP405 demonstrates a statistically significant increase in Ki67 signaling in the hair follicle bulge. Ki67 is a well-established marker of stem cell proliferation.

Pelage Pharmaceuticals Raises $16.75 Million and Phase 2 Trials to Begin in 2024

Pelage Pharmaceuticals has raised $16.75 million in Series A Financing. More importantly, they will begin Phase 2 Clinical Trials for PP405 in mid-2024.

Phase I clinical data met primary safety endpoints. And they confirm that their was statistically significant stem cell activation in hair follicles after just one week of treatment with PP405.

Per CEO Daniel Gil, Ph.D.:

“Our scientific co-founders have uncovered a unique biological mechanism with the potential to reactivate hair growth in people with alopecia.”

The company will present translational data at the American Academy of Dermatology meeting in March 2024.

Recently, reader “Ben” made an very interesting discovery on Pelage Pharmaceuticals’ website. The following sentence at the bottom:

“Early Phase I clinical data shows statistically significant stem cell activation in the hair follicles after one week of treatment with PP405.”

This is super news. So their trials have started. I wonder if PP405 is RCGD423 or UK5099? I think it sounds like that latter. The company’s website homepage describes PP405 as:

“A novel, non-invasive, topical small molecule drug platform that activates stem cells in the hair follicles directly to stimulate robust hair growth. By targeting an intrinsic metabolic switch in hair follicles, Pelage’s platform is suitable for all genders, skin types, and hair types.”

In other recent news, Pelage appointed Dr. Qing Yu Christina Weng as Chief Medical Officer.
