We are experiencing 4 week turn-around time in review of submissions and resubmissions. We recommend commencing this process concurrently with your ethics submission and allowing at least 8 weeks for registration to be completed from date of first submission. We currently do not have the capacity to expedite reviews.

Note also there are delays to review of updates. We appreciate your patience.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

angiotensin system including angiotensin-converting-enzyme inhibitors (ACEi) or
angiotensin receptor blockers (ARB);

Can healthy volunteers participate?
Key exclusion criteria
1. Any significant past or current cardiac, pulmonary, hepatic, renal or other medical
condition which in the opinion of the investigator would make participation of the
subject in this study medically unsafe or compromise the accuracy of assessment of
safety, pharmacokinetic and pharmacodynamic data of the study;

2. Subjects who have abnormal safety labs outside the local lab ranges will be excluded
at PI's discretion based on his/her assessment of clinical significance (can be
repeated once at screening at PI's discretion);

3. Subjects with past medical history of malignancy except basal cell or squamous cell
carcinoma of the skin who have had curative surgical treatment and at least 6 months
have elapsed since the procedure;

4. A value outside the specified range of 90 mm Hg - 140 mm Hg for systolic blood
pressure and 50 mm Hg - 90 mm Hg for diastolic blood pressure (both inclusive) at
screening (can be repeated once at screening as per PI's discretion);

5. Subjects using angiotensin-converting-enzyme inhibitors (ACEi) or angiotensin receptor
blockers (ARB) to control blood pressure;

6. History of clinically significant acute bacterial, viral, or fungal systemic
infections in the last 4 weeks prior to screening;

7. Clinical or laboratory evidence of an active infection at the time of screening;

8. Known alpha 1-antitrypsin deficiency (a1-antitrypsin deficiency);

9. Serological evidence of human immunodeficiency virus (HIV), hepatitis B surface
antigen (HBsAg), or anti-hepatitis C virus (Anti-HCV) at screening;

10. Vaccination within 3 months of screening for the study or requiring vaccination during
the study or within 3 months after completion of the study;

11. Females who are pregnant or nursing;

12. Females of childbearing potential (i.e., any woman who is not surgically sterile e.g.,
hysterectomy, bilateral oophorectomy or >1-year postmenopause status confirmed by
follicle-stimulating hormone (FSH) levels as defined by established lab ranges) and
all men who, if participating in heterosexual sexual activity that could lead to
pregnancy are unable or unwilling to practice medically effective contraception during
the study. They should agree to use two reliable methods of contraception (e.g.,
double-barrier condom plus diaphragm, condom or diaphragm plus a stable dose of
hormonal contraception) throughout the study period and until 3 months after receiving
study drug. Women of childbearing potential will require compulsory pregnancy testing.
A negative pregnancy test (serum and urine) will be documented during screening and at
Day -1 respectively;

13. Participation in any other drug study within 8 weeks or 5 half-lives of the study
drug, whichever is longer;

14. Unable or unwilling to comply with the protocol requirements for study visits and

15. Subjects who do not have good venous access for infusion of study drug or for blood

Brief summary
This is a Phase 1B study to assess the safety, tolerability and pharmacokinetics of DM199 in
healthy volunteers. The study will be consist of two parts: Part A will focus on intravenous
dosing and Part B will directly compare intravenous dosing with subcutaneous dosing.
