Experimental: Danvatirsen Monotherapy
Patients will be enrolled in cohorts of 3 for the Danvatirsen dose escalation substudy. Based on the DLT of the first cohort of participants, subsequent cohorts will either be administered doses at the next higher dose level, de-escalated to the next lower dose level, or remain the same. Dose escalation discontinuations and MTD will be determined as described in the 'Detailed Study Description.' The total duration of 1 cycle is approximately 4 weeks (28 days). Proposed dose levels and treatment schedule are as follows: Dose Level 1 (DL1): Danvatirsen Day 1 - Day 28 (1mg/kg loading dose on Cycle 1/Day 1 (C1D1), Cycle 1/Day 3 (C1D3); and Cycle 1/Day 5 (C1D5) followed by weekly 1mg/kg infusion for 3 weeks) Dose Level 2 (DL2): Danvatirsen Day 1 - Day 28 (2mg/kg loading dose on C1D1, C1D3, and C1D5 followed by weekly 2mg/kg infusion for 3 weeks) Dose Level 3 (DL3): Danvatirsen Day 1 - Day 28 (3mg/kg loading dose on C1D1, C1D3, and C1D5 followed by weekly 3mg/kg infusion for 3 weeks) |
Drug: Danvatirsen
Danvatirsen (AZD9150) is a selective, high-affinity, antisense oligonucleotide inhibitor of signal transducer and activator of transcription 3 (or STAT3).
Other Name: AZD9150 |
Experimental: Danvatirsen + Venetoclax Combination Therapy
Patients will be enrolled in cohorts of 3 for the Danvatirsen + Venetoclax dose escalation substudy. Dose escalation administration will be as described in the Danvatirsen monotherapy substudy arm and dose escalation discontinuations and MTD will be determined as described in the 'Detailed Study Description.' Up to 2 dose levels of Danvatirsen will be evaluated based on data from the Danvatirsen monotherapy arm. Dose 1 will be one level lower than the dose with expected target activity. Venetoclax: 400 mg (or equivalent) administered as fixed dose daily (except for specific dose modifications described in the protocol) orally for 28 days per cycle. To mitigate risk of tumor lysis syndrome, during Cycle 1 Venetoclax will be dose escalated daily to the goal dose of 400mg daily (100mg on Day 1, 200mg on Day 2 and 400mg on Day 3, and onwards, or adjusted dose ramp-up per Venetoclax label if on concomitant azoles). The three cycles are approximately 28 days each in duration. |
Combination Product: Danvatirsen + Venetoclax
Danvatirsen (AZD9150) is a selective, high-affinity, antisense oligonucleotide inhibitor of signal transducer and activator of transcription 3 (or STAT3). Venetoclax: Commercially available. Venetoclax is a potent, selective small molecule inhibitor of BCL-2, an anti-apoptotic protein found on some types of cancer cells. Other Name: Venclexta |
- Response to Therapy as determined by Overall Response Rate [ Time Frame: From 21 days after initiation of study treatment to within 14 days following treatment discontinuation; up to 14 weeks total ]
Overall Response Rate (ORR) will be used to assess clinical activity in AML and MDS participants. ORR will be measured as the percentage of participants demonstrating an objective overall response based upon a composite of remission related measures for AML and MDS participants as defined below.
For AML participants, ORR will be defined as any confirmed Complete Remission (CR) + Complete Remission with Incomplete hematologic recovery (CRi) + Partial Remission (PR).
or, AML = CR + CRi + PR
For MDS participants, ORR will be defined as any confirmed Complete Remission (CR) + Complete Remission with Partial Hematologic Recovery (CRh) + Hematologic Response (HR).
or, MDS = CR + CRh + HR
Higher percentage is indicative of increased clinical activity of the danvatirsen monotherapy and danvatirsen + venetoclax combination therapies.
- Duration of Response [ Time Frame: Up to 3 years after discontinuation of study treatment; up to 3.5 years total ]Duration of response will be measured by the number of days from the date of initial response (CRi or better) to the date of first documented disease progression/relapse or death, whichever occurs first. In the event that neither disease progression/relapse or death is documented prior to study termination, analysis cutoff, or the start of confounding anticancer therapy, this endpoint will be censored at the date of last tumor assessment date. An increased duration of response is indicative of how long a patient will respond to treatment without tumor growth or metastasis
- Event-free survival [ Time Frame: Up to 3 years after discontinuation of study treatment; up to 3.5 years total ]Event-free survival (EFS) will be measured as the number of days from the date of treatment initiation to the date of documented treatment failure, relapse from complete remission, or death from any cause, whichever occurs first. In the event that none of the above are documented prior to study termination, analysis cutoff, or the start of confounding anticancer therapy, this endpoint will be censored at the date of last tumor assessment date
- Overall Survival [ Time Frame: Up to 3 years after discontinuation of study treatment; up to 3.5 years total ]Overall Survival (OS) will be measured as the number of days from the date of treatment initiation until the date of death
- 30 Day All-cause mortality [ Time Frame: 30 days after initiation of study treatment ]Number of participant deaths by all causes
- 60 Day All-cause Mortality [ Time Frame: 60 days after initiation of study treatment ]Number of participant deaths by all causes
