FightAcne.com: What is the background for this study? What are the main findings?

ResponsePatients with skin of color have a higher risk of acne and inflammation-related complications, including post-inflammatory hyperpigmentation (PIH). Topical retinoids such as tazarotene treat acne in part by reducing inflammation. However, skin irritation and other skin reactions may limit the use of some tazarotene gel and cream formulations. A lower-dose tazarotene 0.045% lotion formulation (Arazlo™, Ortho Dermatologics) was recently developed to treat acne. 

FightAcne.com: How does Tazarotene Cream differ from other medication groups for acne? 

Response:To clarify, our results are on tazarotene lotion, not tazarotene cream. Tazarotene 0.045% lotion is the first lotion formulation of tazarotene, which was created using polymeric emulsion technology. The benefits of this new technology are that the lotion is highly spreadable, and it allows for more efficient delivery of tazarotene deep into the skin while reducing the potential for skin irritation. In a previous study, tazarotene 0.045% lotion had comparable efficacy to tazarotene 0.1% cream but with fewer side effects.

FightAcne.com:  What is the background for this announcement?   

Response: ARAZLOTM (tazarotene) Lotion, 0.045%, was approved by the U.S. Food and Drug Administration in December 2019 and is indicated for the topical treatment of acne vulgaris in patients nine years of age and older. This week, Ortho Dermatologics announced that ARAZLO is available commercially to healthcare professionals.



FightAcne.com: What are the main findings of your study? : Tanghetti EA, Kircik LH, Green LJ, et. Al. A Phase 2 multicenter, double-blind, randomized, vehicle controlled clinical study to compare the safety and efficacy of a novel tazarotene 0.045% lotion and tazarotene 0.1% cream in the treatment of moderate-to-severe acne vulgaris. J Drugs Dermatol. 2019;18(6):542-548

Response: In this Phase 2, head-to-head study, ARAZLO and Tazorac (tazarotene) Cream 0.1% showed similar treatment success rates and similar reductions in both inflammatory and non-inflammatory lesions over 12 weeks. While there were no significant differences in patient satisfaction or quality of life between the two treatments and both were well-tolerated, there were about double the number of treatment-related adverse events with Tazorac (5.6% with Tazorac vs. 2.9% with ARAZLO).

Additionally, ARAZLO was evaluated in two Phase 3 multicenter, randomized, double-blind, vehicle-controlled clinical trials in 1,614 patients with moderate to severe acne. In both Phase 3 studies, ARAZLO showed superiority to vehicle for all primary efficacy endpoints (p<.001). ARAZLO was also shown to be generally well-tolerated in the clinical study population.

In the topical retinoid world, consensus and head-to-head studies all have strongly suggested that tazarotene 0.1% cream and gel is the most potent retinoid in this space. However, irritation has always been a concern and has been one of the main impediments to widespread use. ARAZLO provides the same efficacy of tazarotene 0.1% cream with a significantly better tolerability profile.

First Topical Androgen Inhibitor Tested to Fight Acne

This document was completed by Martina Cartwright, PhD Senior Director, Medical Affairs and Dr. Alessndro Mazzetti, Chief Medical Officer, Cassiopea.  The product being discussed, clascoterone cream 1% is NOT FDA approved and is for informational purposes only.

FightAcne.com:  What is the background for this study?

Response: Androgens play a significant role in the development of acne in both males and females. Oral medications that reduce androgens are used to treat acne in females, but due to side effects, are unsuitable for males.  Clascoterone cream 1% is a novel, topical androgen receptor inhibitor under FDA review as possibly a new first in class treatment for acne in both males and females.  These pivotal phase 3 studies demonstrated favorable efficacy and safety with low adverse event rates. 

FDA Approves Ortho Dermatologics’ ARAZLO (Tazarotene) Lotion, 0.045%, For Acne Vulgaris

Emil Tanghetti, M.D., FAAD

FightAcne.com:  What is the background for this study?  What are the main findings?

Response: This new tazarotene lotion is a game changer, by enhancing the delivery of the active drug with the polymeric lotion vehicle we are able to get efficacy that is similar to the higher concentration of tazarotene. This vehicle also permits the simultaneous delivery of emollients and humectants. Both these factors provide a much better tolerability profile than the older preparations. The main impediment in the past to using tazarotene was irritation. With this new formulation, this concern is no longer of paramount importance. This vehicle is cosmetically elegant and highly spreadable, which should make it an ideal product for the face, chest and back.

Study Finds Chromophore Gel-Assisted Blue Light Phototherapy Improves Acne



This new study if a follow up of a study evaluating the KLOX BioPhotonic System, an LED blue light device using photo-converter chromophores, that demonstrated ” significantly improved moderate and severe facial acne vulgaris with an excellent safety profile”.

The current study extended the findings an additional 12 weeks and found ” The BioPhotonic System, which is comprised of LED blue light phototherapy and photo-converter chromophores, provides long-term efficacy and safety in the treatment of acne vulgaris, with a rate of compliance above what is generally observed in a young population of patients suffering from acne vulgaris, especially in light of sequential enrollment in a study treating one hemiface.”

Possible Link Between Adolescent Acne and Later Life Prostate Cancer



A Swedish study found #that men with acne had a statistically signicant increased risk of prostate cancer later in life compared with men without acne”.  The link between the two may be the acne-associated bacteria Propionibacterium acnes.

Pediatric Acne Microbiome Differs From Older Teens



‘The predominant bacteria in microbiome studies of adult acne is Propionibacterium, whereas in this pediatric population we saw a lot of Streptococcus bacteria. After treatment, the microbiomes of intervention group participants more closely resembled those of control group participants.’
