PTC announces long-term data on Duchenne drug
08 October 2018
PTC Therapeutics recently presented positive preliminary data on the long-term clinical benefit of Translarna at the World Muscle Society conference. Data collected from 216 treated children showed that some boys were able to walk up to five years longer compared to untreated children (based on natural history data).
PTC Therapeutics has been working in partnership with TREAT-NMD to collect this information through the STRIDE registry. No long-term safety concerns of Translarna were reported.
For further information pleases read PTC Therapeutics’ press release.
Update from X-MTM gene therapy trial
5 October 2018
Today at the World Muscle Society conference, Audentes Therapeutics announced new data from its ASPIRO study testing a gene therapy for X-linked myotubular myopathy (X-MTM). Eight children have been enrolled to date; six have received a low dose of the gene therapy, one received a higher dose and one has not yet been treated (to act as a control). All treated children continue to show improvements in respiratory and neuromuscular function and no new safety issues have been reported since the company’s update in May 2018. Three children no longer require any ventilation support, which is “an unprecedented outcome in children with a congenital myopathy who have been ventilated from birth”.
Audentes also announced that it plans to hold initial discussions with the US Food and Drug Administration (FDA) and European Medicines Agency (EMA) beginning in the fourth quarter of 2018.
For more information, please see Audentes’ press release.
Update on PTC’s SMA trials
03 October 2018
PTC Therapeutics has released preliminary data from its ongoing clinical studies, FIREFISH and SUNFISH. These studies are investigating whether RG7916 (risdiplam) could be a potential treatment for spinal muscular atrophy (SMA).
So far, the FIREFISH study has shown that infants with Type 1 SMA treated with RG7916 have reached new developmental milestones (e.g head control and sitting). The SUNFISH study – which is focussed on people with Type 2/3 SMA – has also shown that RG7916 can improve motor function.
No severe adverse events have been reported to date, suggesting that the drug is safe and well-tolerated.

FDA lifts ban on Duchenne gene therapy trial
24 September 2018
The US Food and Drug Administration (FDA) has lifted its clinical hold on Sarepta’s Duchenne gene therapy trial. This hold was recently imposed by the FDA due to manufacturing issues. The company has now addressed this and plans to restart its gene therapy clinical program.
The company will also meet with the FDA to discuss the possibility of starting a pivotal Duchenne gene therapy trial by the end of 2018. Data from this trial would be used to seek marketing approval from the FDA.
For more information please read Sareta’s press release.

Update from myotubular myopathy trial
07 August 2018
Audentes Therapeutics has announced additional interim results from the first three treated children in its ASPIRO study. Muscle biopsies taken at the 24 week time point have shown increased levels of the myotubularin protein as well as improvements in the overall health of the muscle. No new safety concerns have been reported.
The company also announced that a higher dose of therapy will be administered to the next group of participants in the coming weeks.
Mallinckrodt starts Duchenne trial
03 August 2018
The first participant has enrolled into Mallinckrodt Pharmaceuticals’ phase 2 trial testing MNK-1411 as a potential treatment for Duchenne.

PTC highlights clinical benefit of deflazacort in Duchenne
25 July 2018
PTC Therapeutics has published data highlighting the clinical benefit of deflazacort. The company analysed functional data (e.g. walking ability and stair climbing) of the 114 boys who were in the control group during the ACT DMD Translarna trial. About half of these boys were taking deflazacort and half were taking prednisone as part of standard care. PTC’s analysis showed that the boys taking deflazacort had a slower functional decline over 48 weeks than those taking prednisone.
It’s important to remember that the ACT DMD trial was primarily focussed on demonstrating the effectiveness of Translarna, not deflazacort or prednisolone. Therefore further research is required to confirm which steroid is better.
New artificial intelligence company focuses on Duchenne
20 July 2018
Insilico medicine and A2A Pharmaceuticals have announced they have formed a new company – Consortium.AI – which will focus on identifying potential treatments for Duchenne. Both companies specialise in using complex computer programmes to design and identify new drug targets for a range of conditions. By combining their expertise, they hope to drive the development of new drug compounds for Duchenne.
For information, please read Insilico medicine’s press release.
Positive data from recent Translarna trial
10 July 2018
PTC Therapeutics has released data from its recent trial testing Translarna in boys between two and five years old. Whilst the study was small, it did show the drug was well tolerated and the boys improved in their timed function tests (e.g. stair climbing and rising from the floor).
Data from this trial encouraged the Committee for Medicinal Products for Human Use to recommend the expansion of the drug’s current licence to include boys as young as two.
For more information please read PTC’s press release.
