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.

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.

Antifungal drug eliminates sleeping bowel cancer cells in mice

In continuation of my update on  itraconazole 

An antifungal medication, commonly prescribed for toenail infections, could help eliminate dormant cells within bowel tumours, according to new research funded by Cancer Research UK and published in the Journal of Experimental Medicinetoday.

Researchers at the Cancer Research UK Cambridge Institute have shown in laboratory studies in mice, that itraconazole effectively halts the growth and progression of certain types of bowel cancer. The next step will be to see if this holds true in patients with the disease.
Dr. Simon Buczacki, co-lead author and Cancer Research UK clinician scientist, said: "One of the biggest challenges in treating any cancer is the diversity of different cells within the same . We've targeted a type of cell that lies asleep within bowel tumours, remaining unresponsive to  and putting the patient at risk of their cancer coming back."
The Cambridge team characterised the molecular nature of dormant bowel cancer cells. These 'sleeping' cells are resistant to drugs, including chemotherapy, which work by targeting cells that are actively growing. So even if it looks like a treatment has worked, some of these dormant cells can later awaken after treatment has finished and lead to the tumour re-growing.
The scientists identified two key pathways involved in cell dormancy and used miniature bowel tumours grown from the cells of mice with cancer, to test different drugs targeting these pathways.
They found, for the first time, that itraconazole blocked signals from a pathway called Wnt, which is implicated in the growth and spread of many different cancers. This led to the tumours collapsing in the mice—dormant cells disappeared and the tumour stopped growing.
"What's interesting is that this  seems to kick both dormant and non-dormant cells into action," added Dr. Simon Buczacki. "It forces cells back into a short cycle of growth before slamming on an irreversible 'stop' button, entering a permanent standstill that's known as senescence."
The next stage will be to test this drug in people. The researchers hope to set up a clinical trial where they can test its effect on patients with hard to treat advanced  cancer. They also intend to investigate whether this drug could be more effective in combination with other treatments like chemotherapy.
Professor Greg Hannon, director of the Cancer Research UK Cambridge Institute, said: "This innovative study has taken a step toward addressing one of the biggest challenges in cancer research. Tumours are made up of many different types of cancer cells, which can evolve separately and respond to treatments differently.
"The presence of drug-resistant, dormant tumour cells is a problem in many types of . If we find ways to target these cells in , it might provide insights into tackling the problem of dormant tumour  more broadly."

In continuation of my update on Itraconazole
Anti-fungal drug shows promise as potential new cancer treatment.A common anti-fungal treatment has joined the ranks of drugs that may be suitable for use in treating cancer, according to research from the Repurposing Drugs in Oncology (ReDO) project published in ecancermedicalscience.  

The ReDO project is an international collaboration of anticancer researchers dedicated to promoting the cause of common medicines which may represent an untapped source of novel therapies for cancer.

In partnership with ecancer, the ReDO project is publishing a series of papers on drugs that have enough clinical evidence to be taken to clinical trials.Itraconazole is a drug used to treat a broad range of fungal infections, including skin and nail infections.

It also has a lot of potential as a new cancer treatment, according to the ReDo project.
"Itraconazole shows potential in a number of areas with high unmet patient needs, particularly in non-small cell lung cancer and possibly in some rarer malignancies," says Pan Pantziarka, PhD, member of the ReDO project and the Anticancer Fund.

Nearly five million asthmatics worldwide could benefit from antifungal therapy


Clinical studies have shown that oral antifungal drugs significantly improve symptoms and asthma control in asthmatics with ABPA, treatment endorsed by the Cochrane Collaboration. This is the first time that a global estimate of ABPA numbers has been made.
In national league tables of asthma rates in adults, only Australia and Sweden have a higher prevalence than the UK. In global league tables of ABPA occurrence, New Zealand tops the list with a 3.5% rate in new patients attending chest clinics at hospitals. The rates were 2.6% in Cape Town, 2.3% in Saudi Arabia, 2.5% in China and 0.7% in an older study from Ireland. No population-based studies have been done.
Itraconazole


Posaconazole


Voriconazole



In addition to standard asthma therapy, the antifungal therapy used is itraconazole  now a generic, inexpensive antifungal  with a response rate of 60%. The researchers also found that antifungal therapy also benefits patients with severe asthma sensitized to fungi, called SAFS.
Alternatives include voriconazole and posaconazole, which have 75-80% response rates. In a recent assessment of voriconazole and posaconazole for both ABPA and SAFS, 75% of patients were able to stop taking oral corticosteroids, a major benefit, and 38% of patients had their asthma severity downgraded on antifungal therapy.
Professor David Denning, professor of medicine and medical mycology at the University of Manchester and Director of the University Hospital of South Manchester's National Aspergillosis Centre, led the study into the total number of asthmatics worldwide. He said the study results implied that asthma admissions and deaths could be avoided with more extensive use of antifungal therapy.
"We were surprised by the number of patients with ABPA, and by the lack of community based studies done," he said. "Our National Aspergillosis Centre treats hundreds of these patients each year, generally with major improvement, and so a conscious program to seek out ABPA from all asthmatics is required."
Professor Donald Cole of the Dalla Lana School of Public Health at the University of Toronto was the senior author of the study and contributed his expert epidemiological knowledge to the development of the model and provided a 'reality' check of the model's estimates.
