Brief Summary

The purpose of this study is to evaluate the safety and tolerability of ASP1235 (AGS62P1) given at three dosing schedules (Schedule A, every three weeks \[Q3W\] or Schedule B, every other week of a 4 week cycle \[Q2W\] or Schedule C once a week for 3 weeks of a 4 week cycle) in subjects with acute myeloid leukemia (AML) and determine the maximum tolerated dose (MTD). In addition, this study will assess the pharmacokinetics (PK), the immunogenicity and the anti-leukemic activity of ASP1235 (AGS62P1).

Dose Escalation of ASP1235 (AGS62P1) Schedule B

EXPERIMENTAL

Subjects will receive ASP1235 (AGS62P1) as an intravenous infusion every other week of a 4-week cycle (Q2W) to determine the maximum tolerated dose (MTD) or recommended Phase 2 dose. A cycle is 28 days.

Drug: ASP1235

Dose Expansion of ASP1235 (AGS62P1) Schedule A

Once the maximum tolerated dose (MTD) or recommended Phase 2 dose has been determined, an expansion cohort of up to 25 subjects may be enrolled. Subjects will receive ASP1235 (AGS62P1) as an intravenous infusion once every three weeks (Q3W).

Drug: ASP1235

Dose Expansion of ASP1235 (AGS62P1) Schedule B

EXPERIMENTAL

Once the maximum tolerated dose (MTD) or recommended Phase 2 dose has been determined, an expansion cohort of up to 25 subjects may be enrolled. Subjects will receive ASP1235 (AGS62P1) as an intravenous infusion every other week of a 4-week cycle (Q2W).

Drug: ASP1235

Dose Escalation of ASP1235 (AGS62P1) Schedule C

EXPERIMENTAL

Subjects will receive ASP1235 (AGS62P1) as an intravenous infusion once weekly for three weeks of a 4-week cycle to determine the MTD or recommended Phase 2 dose. A cycle is 28 days.

Drug: ASP1235

Dose Expansion of ASP1235 (AGS62P1) Schedule C

EXPERIMENTAL

Once the MTD or recommended Phase 2 dose has been determined, an expansion cohort of up to 25 subjects may be enrolled. Subjects will receive ASP1235 (AGS62P1) as an intravenous infusion once weekly for three weeks pf a 4-week cycle.

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Subject has morphologically documented primary or secondary AML by the World Health Organization (WHO) criteria (2008) which is relapsed or refractory after failing at least 1 regimen and is not a candidate for established salvage treatment regimens. For expansion cohorts, patients are eligible if they have had ≤ 3 prior lines of therapy. Lines of therapy include initial induction (up to 2 cycles) with consolidation/maintenance, if applicable, and subsequent salvage regimens. Consolidation alone and stem cell transplantation are not counted as lines of therapy.
• Subject has an Eastern Cooperative Oncology Group performance score (ECOG) ≤ 2
• Subject has adequate renal function with an estimated creatinine clearance of ≥ 30 mL/min by the Cockcroft-Gault equation adjusted for body weight
• Subject has a total bilirubin ≤ 1.5 x upper limit of normal (ULN), albumin ≥ 2.5 g/d, aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤ 2.5 x upper limit of normal (ULN)
• Subjects must be competent to comprehend, provide written informed consent, and date an independent ethics committee/institutional review board/research ethics board (IEC/IRB/REB) approved informed consent form
• A female subject is eligible to participate if she is not pregnant and at least one of the following conditions applies:
• Not a woman of childbearing potential (WOCBP) OR
• WOCBP who agrees to follow the contraceptive guidance throughout the treatment period and for at least 6 months after the final study drug administration.
• Female subject must agree not to breastfeed starting at screening and throughout the study period, and for 6 months after the final study drug administration.
• Female subject must not donate ova starting at screening and throughout the study period, and for 6 months after the final study drug administration.

• Subject has any Grade ≥ 2 persistent non-hematological toxicity related to allotransplant
• Subject with Graft vs. Host Disease (GVHD) who is receiving treatment with systemic glucocorticoids \> 10 mg/day equivalent of prednisone; however, treatment with low dose glucocorticoids (≤ 10 mg/day equivalent of prednisone) is permitted
• The use of systemic glucocorticoids in excess of 10 mg/day equivalent of prednisone is permitted provided it is not for the treatment of GVHD (e.g. chronic obstructive pulmonary disease, anti-emetic, infusion reactions). The chronic use of topical, inhaled, and locally injected steroids is permitted
• Subject has known current central nervous system (CNS) disease
• Active angina or Class III or IV Congestive Heart Failure (CHF) (New York Heart Association CHF Functional Classification System) or clinically significant cardiac disease within 12 months of the first dose of study drug, including myocardial infarction, unstable angina, Grade 2 or greater peripheral vascular disease, congestive heart failure, uncontrolled hypertension, or arrhythmias not controlled by medication
• Subject has clinical evidence of Disseminated Intravascular Coagulation
• Subject has known positivity for human immunodeficiency virus
• Subject has known active hepatitis B (positive hepatitis B surface antigen \[HBs Ag\]) or C infection. For subjects who are negative for HBs Ag, but hepatitis B core antibody (HBc Ab) positive, an HB deoxyribonucleic acid (DNA) test will be performed and if positive, the subject will be excluded. Subjects with positive serology but negative hepatitis C virus (HCV) ribonucleic acid (RNA) test results are eligible.
• Subject has an uncontrolled active infection requiring treatment and grade 3 or higher fever 48 hours before the first dose of study drug. Controlled infections (i.e. 3 negative cultures completing antibiotics and/or stable fungal infection in therapy) are allowed provided the subject has a temperature of \< 38.3°C within 48 hours of the first dose of study drug.
• Subject has a known sensitivity to any of the components of the investigational product ASP1235 (AGS62P1):
