Clinical Trial Summary

A Phase 1 Study to Examine Pharmacodynamic Interaction Between Tesofensine and Metoprolol on 24-hours Mean Heart Rate

Description:

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.

2. Subject had any disorder that would interfere with the absorption, distribution, metabolism or excretion of drugs.

3. Subject had a clinically significant abnormality following the Investigator's review of the physical examination, ECG and clinical study protocol (CSP)-defined clinical laboratory tests at Screening or admission to the clinical unit or had any concurrent disease or condition that, in the opinion of the Investigator, would make the subject unsuitable for participation in the clinical study. One re-test was allowed, if (a) test result(s) was outside the limits.

4. History or presence of liver disease or liver injury, as indicated by abnormal liver

function tests including:

If a mean ECG parameter of a triplicate ECG exceeded the limits above, an additional triplicate ECG could have been taken. If this also gave an abnormal result, the subject was excluded. Also, the following cardiac conditions led to exclusion of the subjects: Untreated heart failure (pulmonary oedema, impaired blood flow or hypotension) and continuous or intermittent treatment leading to an increased contractility of the heart muscle (beta-receptor agonism); sick sinus syndrome; cardiogenic shock; severe peripheral arterial circulatory disturbances.

Primary	Dose of Metoprolol Resulting in no Change in Mean Heart Rate Over 24 Hours (M24HR)	The dose of metoprolol which resulted in no change relative to baseline in mean heart rate over 24 hours (M24HR) for each respective dose of tesofensine was calculated from a dose response relationship with the log-dose of metoprolol as independent variable and change in M24HR induced by various doses of metoprolol given to subjects on steady-state dose of tesofensine as the dependent variable. The dose for no change in M24HR derived from above calculation and the corresponding 95% confidence interval (CI) is presented for each dose of tesofensine. The result in this endpoint is not an arithmetic mean, but the model derived estimated dose from the model. Mitigating dose was estimated using a linear regression modelling mean change from pre-tesofensine baseline (Day -1) of M24HR as a function of the log metoprolol dose.	Day -1 to Day 23
