Main objective of the trial

The primary objective of the study is to assess the efficacy of two doses of SOM3355 (400 mg/day and 600 mg/day taken twice daily [BID] over at least 8 weeks at maintenance dose) compared to placebo to reduce chorea in HD patients measured by the change in TMC score (primary efficacy endpoint).

Das Hauptziel der Studie besteht darin, die Wirksamkeit von zwei Dosen SOM3355 (400 mg/Tag und 600 mg/Tag zweimal täglich eingenommen [BID] über mindestens 8 Wochen bei Erhaltungsdosis) im Vergleich zu Placebo zur Reduzierung der Chorea bei HK-Patienten, gemessen anhand der Veränderung des TMC-Scores (primärer Wirksamkeitsendpunkt).

E.2.2

Secondary objectives of the trial

To evaluate the safety and tolerability of two doses of SOM3355 (400 mg/day and 600 mg/day taken) compared with placebo in HD patients, with particular attention to depression and suicidality and to the cardiovascular hemodynamic parameters.
And to evaluate the efficacy of the two doses of SOM3355 (400 mg/day and 600 mg/day taken BID) compared with placebo on:
the change of Clinical Global Impression (CGI C),
the change of Patient Global Impression (PGI-C),
the percentage of responders based on the improvement ≥2 in TMC score,
the percentage of change of TMC score.

E.2.3

Trial contains a sub-study

Yes

E.2.3.1

Full title, date and version of each sub-study and their related objectives

A PK sub-study will be conducted to characterize the PK profile of repeated doses of SOM3355 at 400 and 600 mg/day. This analysis will be performed by collecting 12-hour PK samples (H0, H0.5, H1, H1.5, H2, H3, H5, H8, and H12) in 8 patients per arm (24 patients in total) that will be hospitalized for 24 hours at Visit 2. In addition, cardiac and hemodynamic parameters will be collected in parallel, with 12-hour cardiac Holter and blood pressure measurements before each PK sample, to allow PK-PD modeling assessments. These patients will be recruited by 3 or 4 sites able to manage the logistics of PK sampling.

Eine PK-Unterstudie wird durchgeführt, um das PK-Profil von wiederholten Dosen von SOM3355 bei 400 und 600 mg/Tag zu charakterisieren. Diese Analyse wird durchgeführt, indem 12-Stunden-PK-Proben (H0, H0,5, H1, H1,5, H2, H3, H5, H8 und H12) bei 8 Patienten pro Studienarm (insgesamt 24 Patienten), die bei Besuch 2 24 Stunden stationär aufgenommen werden, entnommen werden. Darüber hinaus werden parallel kardiale und hämodynamische Parameter erfasst, mit 12-stündigen Langzeit-EKG- und Blutdruckmessungen vor jeder PK-Probe, um PK-PD-Modellbewertungen zu ermöglichen. Diese Patienten werden von 3 oder 4 Prüfzentren rekrutiert, die in der Lage sind, die Logistik der PK-Probenahme zu verwalten.
