FDA Approves Arazlo (tazarotene) Lotion for the Topical Treatment of Acne Vulgaris

In continuation of my update on tazarotene

Bausch Health Companies Inc. (NYSE/TSX: BHC) and its dermatology business, Ortho Dermatologics, one of the largest prescription dermatology health care businesses,  announced the U.S. Food and Drug Administration (FDA)   approval of   the New Drug Application for Arazlo (tazarotene) Lotion, 0.045%, for the topical treatment of acne vulgaris in patients nine years of age and older.1 Arazlo is the first tazarotene acne treatment available in a lotion form, and has been shown to provide strong efficacy with favorable tolerability.

"Today's approval of Arazlo showcases our continued commitment to expanding our acne portfolio to help the approximately 50 million Americans who are impacted by this prevalent skin condition," said Bill Humphries, president, Ortho Dermatologics. "As our fourth FDA approval in just 14 months, Arazlo will provide dermatologists the efficacy expected of tazarotene in a new formulation that helps minimize the dryness and irritation historically associated with tazarotene use, which can cause many acne patients to discontinue treatment. We are purposely timing the launch of Arazlo to coincide with the start of acne season in the first half of 2020."

Retinoids like tazarotene are a core component of acne treatment. However, a common barrier to their use is that treatment with retinoids is often associated with skin irritation, such as dryness.2 In a head-to-head study, Arazlo demonstrated similar efficacy as Tazorac (tazarotene) Cream 0.1% with about half the adverse events.2  The most frequent adverse events reported with Arazlo (≥1%) were application site pain, dryness, exfoliation, erythema and pruritus.1

"Many of my patients with moderate to severe acne can benefit from the efficacy of tazarotene, but struggle to stay on treatment due to tolerability issues," said Emil Tanghetti, M.D., lead Arazlo study investigator and founder, Center for Dermatology and Laser Surgery, Sacramento, Calif. "Tazarotene has typically been reserved only for patients with severe acne, but offering it in a well-tolerated lotion formulation that includes hydrating agents can help more patients with most types of acne take advantage of its efficacy. I look forward to adding Arazlo to my practice armamentarium."

Arazlo Comprehensive Clinical Data

The FDA approval for Arazlo was based on data from 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, all primary efficacy endpoints were met with statistical significance (p<.001). Arazlo was also shown to be generally well-tolerated in the clinical study population.

In a 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 numerically about double the number of treatment-related adverse events with Tazorac (5.6 percent with Tazorac versus 2.9 percent with Arazlo).

FDA Approves Duobrii (halobetasol propionate and tazarotene) Lotion 0.01%/0.045% for Plaque Psoriasis In Adults

                                                                                                                      Tazarotene

Bausch Health Companies Inc. (NYSE/TSX: BHC) and its dermatology business, Ortho Dermatologics, one of the largest prescription dermatology health care businesses, announced,  that the U.S. Food and Drug Administration (FDA) has approved the New Drug Application for Duobrii (halobetasol propionate and tazarotene) Lotion, 0.01%/0.045%, indicated for the topical treatment of plaque psoriasis in adults. Duobrii is the first and only topical lotion that contains a unique combination of halobetasol propionate and tazarotene in one formulation. In a year-long safety study, patients used Duobrii Lotion for up to 24 weeks of continuous use and up to 52 weeks of as-needed use.2 Duobrii is expected to be available in June 2019.

"With today's approval of Duobrii, patients suffering from plaque psoriasis now have an innovative topical treatment option that uniquely combines two well-known ingredients, halobetasol propionate and tazarotene, with established safety profiles, into a single lotion featuring dual mechanisms of action," said Bill Humphries, president, Ortho Dermatologics. "Since psoriasis is a chronic skin disease, patients require continuous treatment in order to achieve optimal control of their symptoms. Now, with Duobrii, health care professionals and their patients have a new topical treatment option that can help them achieve those long-term goals. As a result, we believe that Duobrii has the potential to delay some patients from switching to more expensive biologic treatments, which could potentially result in health care savings."

Continued Mr. Humphries, "We remain committed to bringing forward new medicines, like Duobrii, to add to our portfolio of topicals and biologics to meet the varying treatment needs of patients with psoriasis."

When used separately to treat plaque psoriasis, the duration of use of halobetasol propionate is limited by FDA labeling constraints and the use of tazarotene can be limited due to tolerability concerns. By combining halobetasol propionate and tazarotene in an advanced, patented once-daily moisturizing lotion, the Duobrii formulation ensures uniform distribution, allowing for simultaneous contact with the skin surface.

In the United States, approximately 7.5 million people live with psoriasis, with 80 percent having plaque psoriasis.3 Plaque psoriasis is the most common type of psoriasis, a chronic, non-contagious skin disease that alters the life cycle of skin cells, causing them to build up rapidly on the surface of the skin.

"Duobrii provides the known benefits of a potent topical corticosteroid and a topical retinoid with synergistic efficacy. Combination therapy is the mainstay of topical treatment for plaque psoriasis, making Duobrii an important new option," said Linda Stein Gold, M.D., director, Dermatology Clinical Research, Henry Ford Health System. "Although effective, topical retinoids have had limited use as monotherapy due to tolerability concerns. Duobrii provides improved local tolerability, allowing patients to benefit from an extended duration of use."

FDA Approves Tolsura (SUBA®-itraconazole capsules) for the Treatment of Certain Fungal Infections

In continuation of my update on Itraconazole

Mayne Pharma Group Limited (ASX: MYX) announced,  that the US Food and Drug Administration (FDA) has approved the New Drug Application (NDA) for Tolsura™ (SUBA®-itraconazole) 65mg capsules. Tolsura is a new formulation of itraconazole indicated for the treatment of certain systemic fungal infections in adult patients.

Tolsura is indicated for the treatment of blastomycosis (pulmonary and extrapulmonary), histoplasmosis (including chronic cavitary pulmonary disease and disseminated, non-meningeal histoplasmosis) and aspergillosis (pulmonary and extrapulmonary, in patients who are intolerant of or who are refractory to amphotericin B therapy). These serious infections most commonly occur in vulnerable or immunocompromised patients, for example, those with a history of cancer, transplants (solid organ or bone marrow), HIV/AIDS, or chronic rheumatic disorders, and are often associated with high mortality rates or long-term health issues.

Mayne Pharma's CEO, Mr Scott Richards said, "We are very pleased to have received FDA approval of this patented formulation of itraconazole which incorporates Mayne Pharma's proprietary SUBA technology to improve the bioavailability of poorly soluble drugs. Reformulation of existing drugs plays an important role in improving patient compliance and clinical outcomes. We are proud to offer a new treatment option for patients with these life-threatening infections. We believe physicians will appreciate having access to Tolsura, which has been shown in clinical studies to have increased bioavailability and significantly reduced variability when compared to conventional oral itraconazole capsules."

"After many years of research and development and working closely with key global opinion leaders in infectious disease management, Tolsura represents a major milestone in the SUBA (SUper-BioAvailable) drug delivery platform at Mayne Pharma."

The Company will directly commercialise Tolsura and plans to launch in January 2019 with a new institutional sales team focused primarily on hospital-based infectious disease specialists. Tolsura has four granted patents from the United States Patent and Trademark Office with expiry dates ranging from 2023 to 2033.

The US anti-fungal triazole market has a current value of US$600m according to IQVIA and based on the clear unmet clinical need in serious systemic infections, the addressable market is estimated at US$200m[1].

Mayne Pharma directly markets more than 60 products in the US including three patent protected dermatology products Fabior® (tazarotene) foam, Sorilux® (calcipotriene) foam and Doryx® MPC (doxycycline) delayed-release tablets. The Company recently acquired Lexette® (halobetasol) foam used to treat plaque psoriasis which it expects to also launch in January 2019.

FDA Approves Sorilux for Adolescent Plaque Psoriasis

In continuation of my update on Sorilux(calcipotriene) 

 

Mayne Pharma Group Limited, announced that the US Food and Drug Administration (FDA) has approved Sorilux(calcipotriene) Foam, 0.005% in adolescents.

Sorilux is now approved for treating plaque psoriasis of the scalp and body in patients aged 12 years and older.

The FDA approved Sorilux in 2010 based on evidence from two 8-week placebo controlled clinical trials in patients with mild to moderate plaque psoriasis of the body and one 8-week placebo controlled clinical trial in patients with moderate plaque psoriasis of the scalp. Further data was obtained in a follow-on open label study in patients aged 12 to 17 years of age with psoriasis.

Sorilux Foam contains calcipotriene, a synthetic vitamin D analog that has a similar receptor binding affinity as natural vitamin D. The exact mechanism of action contributing to the clinical efficacy is unknown.

Psoriasis is a chronic disease of the immune system affecting approximately 7.5 million Americans each year[1]. The most common form, plaque psoriasis affects roughly 80 percent of people who have the condition.

Mayne Pharma's CEO, Mr Scott Richards, said "Sorilux is an elegant foam formulation that is marketed by Mayne Pharma's Specialty Brands sales team alongside recently launched LEXETTE™ (halobetasol propionate) Foam, a potent topical corticosteroid also used to treat plaque psoriasis in adult patients. Topical products are the mainstay of treatment for plaque psoriasis patients and the foam delivery platform has a well-established reputation with dermatologists due to ease of application and lack of greasiness and stickiness, especially in hair-bearing areas and under clothing."

Mayne Pharma directly markets more than 60 products in the US including four branded dermatology products FABIOR® (tazarotene) Foam, Sorilux Foam, DORYX® MPC (doxycycline hyclate) delayed-release tablets and LEXETTE Foam. The Company also markets TOLSURA® (SUBA®-itraconazole) capsules used to treat certain fungal infections which was recently approved and launched this year.
