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

carcinoma.

3. Mentally or legally incapacitated, has significant emotional problems at the time of
Screening Visit or expected during the conduct of the study, or has a history of a
clinically significant psychiatric disorder that would impact the subjects ability to
participate in the trial according to the Investigator.

weeks prior to screening; evidence of intestinal infection within 30 days prior to
screening.

5. History of severe allergic or anaphylactic reactions.

6. A supine blood pressure outside the range of 90 to 139 mm Hg systolic and 50 to 89 mm
Hg diastolic, OR heart rate (HR) >100 beats per minute at Screening and at Day -1.

immunodeficiency virus (HIV) antibody at Screening.

9. Subjects considered at high risk of iron deficiency according to the Investigator.

10. Subjects with iron deficiency as defined by a ferritin or transferrin saturation below
the normal range

11. Clinically significant abnormality on ECG performed at the Screening Visit or prior to
administration of the initial dose of study drug.

12. Corrected QT (QTcF) greater than 450 msec at Screening.

13. Subjects with a positive toxicology screening panel.

prescription and non-prescription drugs and herbal remedies (such as St. John's Wort
[Hypericum perforatum]), beginning 14 days (or 5 half lives, whichever is longer)
before administration of the initial dose of study drug and continuing throughout the
study until the final study visit.
