18. Male who has a pregnant partner, and is not willing to use a condom during sexual activity for 3 months after the last dose of protocol-specified therapy
19. Currently receiving treatment in another investigational device or drug study or less than 30 days since ending treatment on another investigational device or drug study(s). The 30 days is calculated from day 1 of blinatumomab treatment.
20. Other investigational procedures while participating in the treatment portion of this study are excluded.
21. Subject has known sensitivity to immunoglobulins or any of the products or components to be administered during dosing.
22. Subject previously entered into this study or previous treatment with blinatumomab.
23. Subject likely to not be available to complete all protocol-required study isits or procedures, including follow-up visits, and/or to comply with all required study procedures including writing tests to the best of the subject and Investigator’s knowledge.
24. History or evidence of any other clinically significant disorder, condition or disease (with the exception of those outlined above) that, in the opinion of the Investigator or Amgen physician, if consulted, would pose a risk to subject safety or interfere with the study evaluation, procedures or completion. |
