Therachon starts phase 1 clinical trial with TA-46 for achondroplasia

| 1 Comment

Therachon announced today, 14 February 2018, the beginning of Phase 1 for the clinical trial with TA-46 for achondroplasia.

This trial will take place in The Netherlands, with 70 adult healthy volunteers and it will be:

  • randomized – A study in which the participants are divided by chance into separate groups that compare different treatments or other interventions. Using the chance to divide people into groups means that the groups will be similar and that the effects of the treatments they receive can be compared more fairly. At the time of the trial, it is not known which treatment is best. Pubmed health
  • placebo-controlled – Studies of new drugs often compare the effects of an investigational drug with the effects of a placebo. The reason for using a placebo control is that the benefits of taking medications are not always due to the drug itself. These benefits are called “placebo effects.” An example is when an investigator’s enthusiasm about a new medication sometimes influences the patient’s response. In a double-blind, placebo-controlled research design, the doctors, nurses working directly with patients, and participants themselves involved in the study, will not know which group patients are in.

  • double-blind trial – is a trial where neither the researchers or patients/participants know what they are getting (the drug or the placebo). The computer gives each patient a code number. And the code numbers are then allocated to the treatment groups. Cancer Research UK

The trial is designed to evaluate the safety, tolerability and pharmacokinetics of single and multiple ascending doses of TA-46.

Luca Santarelli, Therachon´s CEO said that this is “an important milestone for the company,”.

Beyond Achondroplasia has published more information about TA-46 previously (read the first article). The company has high expectations that Ta-46 may show significant therapeutic impact in achondroplasia as may improve anatomical proportions and prevent complications related to achondroplasia, that start to occur in early life phases.

Next steps

Is important to know the timelines for this phase 1 trial, namely the duration of this trial as also the results of safety, tolerability and mechanism of the drug in these healthy volunteers and then, after positive results, know the expected dates of the beginning of phase 2, with children with achondroplasia.

How is expected TA-46 to work?

TA-46 acts as a ligand trap can reduce the superactivation of the mutated receptor FGFR3 (that is overworking in achondroplasia, which reduces the multiplication and development of chondrocytes, that the cells that give origin at the growth plate level, to the bone formation).

TA-46 is being developed as a weekly subcutaneous drug for children and adolescents living with the disease.

And this investigational therapy has received Orphan Drug Designation from the European Medicines Agency (EMA) on the 27th March 2017 and the U.S. Food and Drug Administration (FDA).
