Trial of DFP-10917 vs Non-Intensive or Intensive Reinduction for AML Patients in 2nd/3rd Salvage
Phase III, multicenter, randomized study with two arms (1:1 ratio) enrolling patients with AML relapsed/refractory after 2 or 3 prior induction regimens: Experimental arm: DFP-10917 14-day continuous intravenous (IV) infusion at a dose of 6 mg/m²/day followed by a 14-day resting period per 28-day cycles. Control arm: Non-Intensive Reinduction (LoDAC, Azacitidine, Decitabine) or Intensive Reinduction (High and Intermediate Dose Cytarabine Regimens), depending on the patient's prior induction treatment.
Phase 3 Randomized Trial of DFP-10917 vs Non-Intensive Reinduction (LoDAC, Azacitidine, Decitabine) or Intensive Reinduction (High & Intermediate Dose Cytarabine Regimens) for Acute Myelogenous Leukemia Patients in Second or Third Salvage
Study to compare the rate of complete response (CR) and duration of CR, in patients with relapsed or refractory AML to two or three prior induction regimens that may have included intensive chemotherapy (e.g., "7+3" cytarabine and daunorubicin), epigenetic therapy (i.e., azacitidine or decitabine), or targeted therapy (e.g., FLT-3, IDH-1/2, BCL-2, monoclonal antibody), who will receive DFP-10917 versus non-intensive reinduction (LoDAC, azacitidine, decitabine) or intensive reinduction (high and intermediate dose cytarabine regimens) as a second or third salvage treatment.
Experimental Arm DFP-10917 Dose: 6 mg/m²/day administered by continuous infusion for 14 days followed by a 14-day resting period per 28-day treatment cycle. If a patient experiences a significant treatment-related AE, the patient may undergo one dose reduction of DFP-10917 to 4 mg/m²/day x 14 days for subsequent treatment cycles
Control arm: Non-Intensive Reinduction (LoDAC, Azacitidine, Decitabine) or Intensive Reinduction (High and Intermediate Dose Cytarabine Regimens), depending on the patient's prior induction treatment. Control treatment is to be selected only from among the following. Institutional practice for administering these treatments are permitted, but the dose and days of drug administration should be followed as below.
- LoDAC: 20 mg Cytarabine administered by subcutaneous (SC) injection, twice daily (BID) for 10 days, plus best supportive care per 28-day treatment cycle
- Azacitidine: 75 mg/m²/day administered by SC for 7 consecutive days (or 5+2), plus best supportive care per 28-day treatment cycle
- Decitabine: administered as continuous intravenous (CIV) infusion 20 mg/m² x 5 days plus best supportive care per 28 day treatment cycle
- High DAC = cytarabine at doses of 1-2 g/m²/day for up to 5 days, with a maximum total dose 10 g/m² per course
- FLAG = Days 1-5: fludarabine 30 mg/m² IV over 30 minutes, Days 1-5: cytarabine 1 2 grm/m² over 4 hours daily x 5, and granulocyte colony-stimulating factor 5 mcg/kg or 300 mcg/m² until Polymorphonuclear Neutrophil (PMN) recovery, with or without idarubicin Days 1-3 at 8 mg/m² IV daily x 3 (FLAG-Ida)
- MEC = Days 1-6: mitoxantrone 6 mg/m² IV bolus, etoposide 80 mg/m² IV over 1 hour, and cytarabine 1 grm/m² IV over 6 hrs
- Intermediate DAC = cytarabine 20 mg/m² IV daily x 5
The selection of control arm treatment will be determined by the investigator depending on the patient's prior initial induction and salvage treatment regimen(s), as well as the patient's clinical condition and comorbidities. The investigator will select the patient's control treatment from among the non-intensive or intensive regimens prior to study treatment randomization in order to balance treatment allocation between the experimental and control treatment arms.

Open to people ages 18 years and up
- Histologically or pathologically confirmed diagnosis of AML based on World Health Organization (WHO) classification that has relapsed after, or is refractory to, two or three prior induction regimens that may have included intensive chemotherapy (e.g., "7+3" cytarabine and daunorubicin), epigenetic therapy (i.e., azacitidine or decitabine) , or targeted therapy (e.g., FLT-3, IDH-1/2, BCL-2, monoclonal antibody).
(Relapse is defined as reemergence of ≥5% leukemia blasts in bone marrow or ≥1% blasts in peripheral blood 90 days to 24 months after first CR or CR without complete platelet recovery (CRp). Refractory AML is defined as persistent disease ≥28 days after initiation of intensive induction therapy (up to two induction cycles) or relapse <90 days after first CR or CRp. Refractory disease for patients undergoing hypomethylating agent induction is defined as lack of remission following at least 2 cycles of epigenetic therapy without reduction in bone marrow blast status.)

- Absence of active central nervous system (CNS) involvement by leukemia. Patients with previously diagnosed CNS leukemia are eligible if the CNS leukemia is under control and intrathecal treatment may continue throughout the study.

- The interval from prior treatment to time of study drug administration is < 2 weeks for cytotoxic agents or < 5 half-lives for noncytotoxic agents. Exceptions: Use of hydroxyurea is allowed before the start of study and is to be discontinued prior to randomization. Hydroxyurea may be administered before study start and up to the time of study randomization. At the investigator's discretion, for patients with significant leukocytosis during the early treatment cycles, hydroxyurea may be administered. The hydroxyurea should be discontinued as soon as clinically appropriate.
