A Phase I, Two-part Study to Determine the Recommended Dose and Evaluate the Safety and Tolerability of a Novel Oral Arsenic Trioxide Formulation (ORH-2014) in Subjects With Advanced Hematological Disorders
Advanced Hematological Disorders
About this trial
This is an interventional treatment trial for Advanced Hematological Disorders focused on measuring acute promyelocytic leukemia, APL, arsenic trioxide
Eligibility Criteria
Inclusion Criteria:
Female and male subjects ≥18 years of age with one of the following:
- Relapsed or refractory acute myelocytic leukemia (AML) with nucleophosmin-1 (NPM1) mutations and no available therapies.
- Relapsed or refractory acute promyelocytic leukemia (APL), with no available therapies. Note: Prior exposure to arsenic trioxide is allowed; however, subjects who have failed arsenic trioxide within the last 12 months are not allowed.
- Relapsed or refractory myelodysplastic syndrome (MDS), International Prognostic Scoring System intermediate or high-risk, with no available therapies
- Relapsed or refractory chronic myelomonocytic leukemia (CMML), and other MDS/myeloproliferative neoplasm (MPN) overlap syndromes, with no available therapies
- Relapsed or refractory mantle cell lymphoma (MCL) with no adequate therapies.
- Negative pregnancy test at the Screening visit for women of childbearing potential and willingness to use adequate birth control
- Not willing to undergo, not a candidate for, or not having a donor for immediate (within 3 months from the Screening date) bone marrow transplantation.
Exclusion Criteria:
- Eastern Cooperative Oncology Group performance status of ≥3;
- Absolute myeloblast count ≥20,000/mm^3;
- Administration of any antineoplastic therapy within 5 half-lives of the antineoplastic therapy before the first dose of ORH-2014, with the exception of hydroxyurea that should be discontinued 1 day prior to the first dose of ORH-2014
- Presence of any remaining toxicities due to previous chemotherapy
- Participation in other clinical trials within at least 2 weeks of the first ORH-2014 dose;
- Clinical evidence of active central nervous system leukemia;
- Active and uncontrolled infection
- Major surgery within 2 weeks prior to trial entry;
- Liver function tests above the following limits at Screening: total bilirubin >1.5 x upper limit of normal (ULN) unless related to Gilbert's syndrome or hemolysis; aspartate aminotransferase (AST) and/or alanine aminotransferase (ALT) >2.5 x ULN; for subjects with liver involvement, AST and/or ALT >5 x ULN;
- Serum creatinine >1.5 x ULN and/or creatinine clearance or estimated glomerular filtration rate <30 mL/min
- Impaired cardiac function
- Myocardial infarction of unstable angina within 6 months prior to the planned start date of study drug.

Part 1
Part 2
Subjects will receive oral ORH-2014 at a planned starting dose of 5 mg once daily (QD) in the fasted state. If escalation criteria are met, the administered dose will increase by 5 mg increments to a maximum of 50 mg QD. The starting daily dose is approximately half the typical IV dose (0.15 milligram per kilogram [mg/kg]) extrapolated to a 70-kg person.
Subjects will receive a daily oral dose of ORH-2014 at the recommended dose identified in Part 1. ORH-2014 will be administered in the fasted state.
