A Multiple Ascending Dose Trial Assessing Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of ZP7570

This is a randomised, double-blind, placebo-controlled, multiple ascending dose trial in healthy subjects, randomised to ZP7570 or placebo within each cohort

Forty subjects are planned to be studied in four cohorts in this multiple ascending dose trial. Ten subjects will be allocated to four dose levels. Intermediate dose levels may be applied. A sentinel dosing approach (sequential dosing) will be applied. The entire observation period comprises 51 days starting with a 96 hours in-house stay after the first dose injection, where discharge is planned for Day 5, followed by one outpatient visit. For the second and the third injection dose a 36 hours in-house stay is planned. After the fourth dose injection there is also a 96 hour in-house stay where discharge is planned for Day 26, followed by five outpatient visits and an End of Trial Visit on Day 51. A blinded evaluation of each cohort will be performed by a Trial Safety Group to determine whether the trial will progress to the next planned dose level based on the stopping rules specified in the protocol.

Eligibility Criteria:
Inclusion Criteria:

* Signed and dated informed consent obtained before any trial-related activities. Trial-related activities are any procedures that would not have been done during normal management of the subject.

* Body Mass Index (BMI) between 18.5 and 28.0 kg/m2, both inclusive
* A body weight of at least 60 kg.
* Heart rate after 5 minutes rest in supine position inside the range of 50-90 beats/min at screening

Exclusion Criteria:

* Any history of a disorder which in the investigator's opinion might jeopardize subjects safety, evaluation of results or compliance with the protocol.
* History of gallbladder disease or cholecystectomy.
* History of pancreatitis
* History of major depressive disorder or a Patient Health Questionnaire (PHQ-9) \> 9 completed at screening, or a history of other severe psychiatric disorders (e.g. schizophrenia or bipolar disorder).

* Family history of multiple endocrinological neoplasia type 2 (MEN2) or medullary thyroid carcinoma (MTC).
* Clinically significant abnormal standard 12-lead ECG after 5 min resting in supine position at screening, including a QTcF \> 450 ms (males) or QTcF \> 470 ms (females), PR ≥ 220 ms and QRS ≥ 110 ms.
* History of severe hypersensitivity to medicines or foods or history of severe medicinal/food induced anaphylactic reaction .
* Any clinically significant abnormal hematology, biochemistry, or urinalysis screening tests, as judged by the investigator.
* TSH values outside of normal reference ranges of safety laboratory
* Estimated glomerular filtration rate (eGFR) \< 90 ml/min/1.73 m2, as defined by - Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI).
* Known or suspected hypersensitivity to IMP(s) or related products.
* Systolic blood pressure \< 90 mmHg or \>139 mmHg and/or diastolic blood pressure \< 50 mmHg or \> 89 mmHg (one repeat test will be acceptable in case of suspected white-coat hypertension).
* Symptoms of arterial hypotension
* Women of childbearing potential
* Men with non-pregnant partner(s) of childbearing potential not willing to use male contraception (condom) in addition to a highly effective contraceptive method until 28 days after dosing
* Men with pregnant partner not willing to use male contraception (condom) until 28 days after dosing, in order to avoid exposure of the embryo/fetus to seminal fluid.
