A Study to Examine the Effect of Tesofensine and Metoprolol on the 24-hour Mean Heart Rate

In this study, the dose-response relationship between tesofensine and metoprolol will be examined and thus the optimal dose of metoprolol to mitigate the effects of tesofensine on heart rate (HR) will be determined. HR is the primary endpoint because in the previous studies it has been shown to be the most affected safety endpoint by the effects of tesofensine.

After enrolment of 37 subjects, 2 Subjects (0115 and 0147) in dose cohort 2 experienced prolonged tachycardia (\> 120 beats per minute (bpm) lasting for 30 min) documented in Holter Electrocardiogram (ECG) recording (a stopping criteria of the study). Therefore, the study was temporarily halted on 22 November 2018. Subsequent to the temporary halt, Saniona reviewed all the available data in January and February 2019 and determined that the results obtained from the completed participants were sufficiently robust to answer the questions for which the trial was designed. Therefore, Saniona decided to permanently end the trial on 20 February 2019.
