A UK company is about to start a Phase 1 trial with the drug involving 18 healthy human volunteers and the results are expected to be announced later this year. In an earlier Phase 1 study in nine healthy human volunteers, the treatment was seen to reduce the excretion of sebum by the skin, which is associated with acne development, by up to 70%.
‘The Phase I results are startlingly good,’ said Nigel Blackburn, director of clinical development at the company, Summit, which is organising the trial. ‘Reducing sebum production has been the “holy grail” of acne treatment for 30 years, and there has been little success aside from Roaccutane which has significant side effects.’
The current ‘gold standard’ for acne treatment, Roaccutane can cause a wide range of side effects, including teratogenicity – which leads to abonormalities in the unborn foetus of pregnant women, and has also recently been linked to depression and (inconclusively) to teenage suicides. The market for acne treatments is worth several billion dollars, and any new treatment developed without side effects could potentially reap blockbuster sales.
Although Summit has not disclosed the name of the drug now under evaluation, the company says it represents an entirely new class of compounds for treating acne. ‘At the doses we are looking at any side effects should be mild compared with those resulting from Roaccutane treatment,’ Blackburn commented.
The company hopes to begin critical Phase 2 trials to assess the efficacy of the drug in acne sufferers next year. Depending on the results, the drug could either be formulated as a stand-alone topical treatment or more likely in combination with other existing treatments. The company has already been in talks with several interested companies, who are waiting to see whether the initial results can be repeated in a larger study group.

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
