Fair-skinned people - who traditionally burn the most in the sun - benefited most from an anti-sunburn drug which has finished Phase II human trials, the Professor of Dermatology at Sydney University said today.
Professor Ross Barnetson - a world authority in the field of photobiology, ultraviolet skin damage and the immunology of skin tumours - ran the Phase II human trials at Sydney University, alongside a concurrent trial at Royal Adelaide Hospital. Eighty volunteers took part in the trial.
Results of the trial into the drug Melanotan - which stimulates the production of melanin in the skin - showed that:
"The aim of the trial was to determine how Melanotan could reduce the degree and toxicity of sunburn in 80 healthy volunteers exposed to ultraviolet light both before and after a regime of the drug," said Professor Barnetson. "The fair-skinned people who took Melanotan had half the skin damage after the study compared to before the study. The results showed that fair-skinned people who have developed a tan are less likely to burn."
The drug was administered daily for ten days in each of three consecutive months. Twenty volunteers received placebos. The volunteers, of varying skin types, received controlled levels of UVA and UVB radiation onto a small area of skin resulting in a level of burning similar to spending 30-120 minutes in strong sun without sunscreen. A skin biopsy was taken from each to measure the level of resulting sunburn injury. The volunteers then received a regime of Melanotan, the same UV radiation exposure, and another skin biopsy.
A volunteer in the trial, Rachel Preece, a 25-year-old medical student, said that the drug gave her an even, all-over tan. She said she recognised the protective elements of the tan. "I am not a sun-lover and don’t go on the beach often. Being a medical student I see a lot of bad effects of sun-baking with skin cancers. I would take this drug if it was commercialised."
Professor Alan Cooper, Head of the Department of Dermatology at Sydney’s Royal North Shore Hospital, said: "I think its reasonable that we can consider Melanotan to be an internal sunscreen. Melanin is the body’s natural sunscreen and this is a way of increasing the amount of melanin we have."
Dr Wayne Millen, Managing Director of EpiTan - the biotechnology company developing Melanotan - said he was delighted with the results. "The results improve our chances of commercialising the world’s first prescription sunscreen. There is no other product available today to prevent sunburn apart from sunscreen. We expect Melanotan to be especially beneficial to those people with fair skin types who are most at risk of sunburn injury and therefore of developing skin cancers."
EpiTan recently announced that, following a successful meeting with the United States Food & Drug Administration, it would lodge an Investigational New Drug application in mid-2004. Clinical trials for a newly-developed long-acting implant has begun at Q-Pharm in Queensland. This trial is expected to conclude in May 2004.

Satellites in near-Earth orbit are at risk due to the steady increase in space debris. But their mission in the areas of telecommunications, navigation or weather forecasts is essential for society. Fraunhofer FHR therefore develops radar-based systems which allow the detection, tracking and cataloging of even the smallest particles of debris. Satellite operators who have access to our data are in a better position to plan evasive maneuvers and prevent destructive collisions. From April, 25-29 2018, Fraunhofer FHR and its partners will exhibit the complementary radar systems TIRA and GESTRA as well as the latest radar techniques for space observation across three stands at the ILA Berlin.
The "traffic situation" in space is very tense: the Earth is currently being orbited not only by countless satellites but also by a large volume of space...
An international team of researchers has discovered a new anti-cancer protein. The protein, called LHPP, prevents the uncontrolled proliferation of cancer cells in the liver. The researchers led by Prof. Michael N. Hall from the Biozentrum, University of Basel, report in “Nature” that LHPP can also serve as a biomarker for the diagnosis and prognosis of liver cancer.
The incidence of liver cancer, also known as hepatocellular carcinoma, is steadily increasing. In the last twenty years, the number of cases has almost doubled...
In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.
Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...
