Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

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

5. For AML, WBC count, no upper limit at Screening, but must be <10 x109/L on Day 1 prior to the first dose of study drug. Note: Subjects with excessive blasts may be treated with hydroxyurea until 2 days prior to first dose of study drug to reduce WBC; Platelet count >10,000/µL; Platelet transfusion prior to first dose is permitted.

10. Life expectancy of at least 3 months.
11. A woman of childbearing potential must have a negative serum beta-human chorionic gonadotropin (beta-hCG) at screening and prior to the first dose of study drug.

Examples of highly effective methods of contraception are in Appendix 3, Contraceptive Guidance and Pregnancy.
13. In addition to the user-independent, highly effective method of contraception, a male or female condom is required. Male condoms and female condoms should not be used together (due to risk of failure with friction).
14. A man who is sexually active with a woman of childbearing potential and has not had a vasectomy must agree to use a barrier method of birth control, e.g., either condom with or partner with occlusive cap (diaphragm or cervical/vault caps).
15. Men or women must agree not to donate sperm or eggs (ova, oocytes) for the purposes of assisted reproduction during the study and for at least 3 months after the last study drug administration.
16. For Part 2 (dose expansion): for B-cell NHL, tumor tissue availability is required at baseline unless clinically contraindicated.
