    <detailed_description>
      <textblock>
        This is a Phase 1 study investigating the safety and efficacy of Danvatirsen as a monotherapy&#xD;
        followed by combination with Venetoclax in patients with intermediate/high/very high&#xD;
        myelodysplastic syndromes (MDS) as determined by revised International Prognostic Scoring&#xD;
        System (IPSS-R) or acute myeloid leukemia (AML) who have relapsed or are refractory to&#xD;
        frontline therapy. Danvatirsen is a next generation, high affinity, antisense oligonucleotide&#xD;
        inhibitor of signal transducer and activator of transcription 3 (or STAT3) that has shown&#xD;
        preclinical activity in vitro and good intracellular uptake in vivo in primary patient MDS&#xD;
        and AML stem cells. STAT3 is a transcription factor that is overexpressed and dysregulated in&#xD;
        several malignancies. Venetoclax is a commercially available, potent, selective small&#xD;
        molecule inhibitor of B-cell Lymphoma-2 (BCL-2), an anti-apoptotic protein found on some&#xD;
        types of cancer cells. Prior studies have demonstrated a strong correlation between STAT3 &amp;&#xD;
        Myeloid cell leukemia-1 (MCL-1) overexpression. MCL-1 is a multi-domain anti-apoptotic&#xD;
        protein belonging to the BCL-2 family, which regulates the intrinsic apoptosis pathways and&#xD;
        plays a central role in mediating therapeutic resistance to novel therapies such as&#xD;
        Venetoclax in MDS and AML.&#xD;
  &#xD;
        While FDA approved therapies have moved the field forward in newly diagnosed AML,&#xD;
        relapsed/refractory (R/R) MDS and R/R AML continue to have a dismal prognosis, with a median&#xD;
        overall survival of 4-10 months.&#xD;
  &#xD;
        The study team has designed an innovative clinical trial to study Danvatirsen as monotherapy&#xD;
        followed by combination with venetoclax for the treatment of relapsed/refractory high-risk&#xD;
        MDS/AML. The study team plans to incorporate several important pharmacodynamic endpoints that&#xD;
        will provide a real-time assessment of the effect of STAT3 inhibition in MDS/AML stem &amp;&#xD;
        progenitor cells and the impact on target gene expression. These correlative studies will&#xD;
        help identify subsets of patients that are most likely to respond to STAT3 inhibition.&#xD;
        Although direct targeting and monitoring of aberrant stem cells has recently gained some&#xD;
        traction in AML, it is a novel approach for the treatment of MDS.&#xD;
  &#xD;
        This study has been designed as a Phase 1 dose-escalation protocol of 2 different sub-studies&#xD;
        to evaluate the safety profile, determine the Maximum Tolerated Dose (MTD) of Danvatirsen&#xD;
        monotherapy followed by combination with Venetoclax once safety of Danvatirsen monotherapy is&#xD;
        established. Patients with intermediate/high/very high IPSS-R MDS or AML who have relapsed/or&#xD;
        are refractory to all available frontline therapy with no FDA approved treatment options will&#xD;
        be enrolled in both the sub-studies. The objective of determining the MTD is to be able to&#xD;
        find the minimum safe and biologically effective dose to be the recommended Phase 2 dose. For&#xD;
        both the sub-studies safety, efficacy and assessment of PK/PD will be used to inform the&#xD;
        recommended phase 2 dose.&#xD;
  &#xD;
        Arms/Groups are detailed in the 'Arms/Groups' module of this record. Dose-escalation for each&#xD;
        substudy is as follows:&#xD;
  &#xD;
        Substudy 1 (Danvatirsen Monotherapy): The maximum number of patients to be enrolled in&#xD;
        dose-escalation phase for Danvatirsen monotherapy is 12, and patients will be treated in&#xD;
        cohorts of 3. Based upon study parameters for Bayesian Optimal Interval (BOIN) design with a&#xD;
        target Dose Limiting Toxicity (DLT) rate of 25%, if the observed DLT rate at the current dose&#xD;
        ≤ 0.197, the next cohort of patients will be treated at the next higher dose. If it is &gt;&#xD;
        0.298, dosing will be de-escalated to the next lower dose level. Otherwise the next cohort of&#xD;
        patients will be enrolled at the current dose. Dose escalation will discontinue and the&#xD;
        Maximum Tolerated Dose (MTD) will be determined: (1) once all patients have been enrolled,&#xD;
        (2) 6 patients have been treated at the same dose level with the decision to stay, or (3) all&#xD;
        doses are found to be too toxic. Patients not evaluable for Dose Limiting Toxicities (DLTs)&#xD;
        will be replaced. The total duration of 1 cycle is approximately 4 weeks (28 days).&#xD;
  &#xD;
        Substudy 2 (Danvatirsen + Venetoclax Combination): Dose escalation for the combination&#xD;
        therapy is as described above for the Danvatirsen monotherapy except that dose escalation&#xD;
        will discontinue and Maximum Tolerated Dose (MTD) will be determined: (1) once all patients&#xD;
        have been enrolled, (2) 9 patients have been treated at the same dose level with the decision&#xD;
        to stay, or (3) all doses are found to be too toxic. The total duration of 1 cycle is again&#xD;
        approximately 4 weeks (28 days).&#xD;
  &#xD;
        Dose Modifications (referenced in 'Arms/Groups'):&#xD;
  &#xD;
        Dose modification guidelines apply to both sub-studies and are minimal recommendations.&#xD;
        Further reductions are permitted based on PI's clinical judgment following Sponsor approval.&#xD;
  &#xD;
        In general, in the event of ≥ Grade 3 hematological toxicities, laboratory values should be&#xD;
        monitored weekly (or more frequently until ≤ Grade 2).&#xD;
  &#xD;
        Proposed dose modifications for treatment related toxicity (hematological) Worst Toxicity&#xD;
        (CTCAE V5.0 Grade Recommended Dose Modification) Thrombocytopenia: Grade 4 (Platelet &lt;&#xD;
        25,000/mm3) Dose delay until resolved to ≤ Grade 2&#xD;
  &#xD;
          -  If resolved to ≤ Grade 2 in ≤ 7 days, then maintain dose level&#xD;
  &#xD;
          -  If resolved to ≤ Grade 2 in &gt; 7 but ≤ 21 days, then lower 1 dose level&#xD;
  &#xD;
          -  Permanently discontinue treatment if not resolved to ≤ Grade 3 in 21 days.&#xD;
  &#xD;
        Proposed dose modifications for treatment related toxicity (non-hematological) Worst Toxicity&#xD;
        (CTCAE V5.0 Grade Recommended Dose Modification) Grade 2: Dose delay until ≤ Grade 1 or&#xD;
        baseline and maintain dose level Grade 3: Dose delay until resolved to ≤ Grade 1 or baseline&#xD;
  &#xD;
          -  If resolved in ≤ 7 days, then maintain dose level&#xD;
  &#xD;
          -  If resolved in &gt; 7 days but ≤ 14 days, then lower 1 dose level&#xD;
  &#xD;
          -  If not resolved in ≤ 14 days, then permanently discontinue treatment Grade 4 :&#xD;
             permanently discontinue treatment&#xD;
  &#xD;
        Danvatirsen dose reductions Dose reduction for toxicity is allowed to one dose level below&#xD;
        the current level. For the lowest dose of 1 mg/kg, dose reduction is allowed to 0.5 mg/kg&#xD;
        below that dose level. Once a dose has been reduced for a given patient due to toxicity, this&#xD;
        dose should be administered for all subsequent infusions, unless a further dose reduction is&#xD;
        required. Any subsequent dose re-escalation would require consultation with the PI. Up to 1&#xD;
        dose level reduction is permitted.&#xD;
  &#xD;
        Venetoclax Dose Modifications:&#xD;
  &#xD;
        During cycle 1, venetoclax will be dose escalated daily to the goal dose. Patients will&#xD;
        receive 100mg on Day 1, 200mg on Day 2 and 400mg on Day 3 and onwards, or adjusted dose per&#xD;
        venetoclax label if on concomitant azoles. The goal is to administer 28 days of venetoclax in&#xD;
        cycle 1 unless marrow remission with concomitant marrow hypocellularity and/or&#xD;
        myelosuppression is confirmed earlier than cycle 1 Day 28. In this case the venetoclax may be&#xD;
        stopped earlier to avoid venetoclax related myelosuppression or further marrow hypo/aplasia&#xD;
        after discussion and approval from the PI.&#xD;
  &#xD;
        Initial response assessment will occur after 21 days of study therapy. Participants with&#xD;
        stable or responding disease may continue on study until completion of study if their&#xD;
        treating physician and PI feel that they are deriving clinical benefit. Participants with&#xD;
        significant AEs or progressive disease or those having absence of clinical benefit after 6&#xD;
        cycles of treatment should be removed from study. Duration of therapy will depend on&#xD;
        individual response, evidence of disease progression and tolerance. In the absence of&#xD;
        significant adverse events, treatment may continue indefinitely or until one of the following&#xD;
        criteria applies:&#xD;
  &#xD;
          -  Disease progression&#xD;
  &#xD;
          -  Intercurrent illness that prevents further administration of treatment&#xD;
  &#xD;
          -  Unacceptable adverse event(s)&#xD;
  &#xD;
          -  Participant decides to withdraw from the study OR&#xD;
  &#xD;
          -  General or specific changes in the participant's condition or compliance render the&#xD;
             participant unacceptable for further treatment in the opinion of the treating&#xD;
             investigator.&#xD;
  &#xD;
        All participants should undergo response evaluations between Day 21 and Day 42 of first&#xD;
        and/or second induction course (optional). Unless there is clear evidence of progressive&#xD;
        disease in the blood, bone marrow aspiration is required and bone marrow biopsy is strongly&#xD;
        encouraged. In cases with hypocellular marrows (&lt;10% cellularity), repeat bone marrow&#xD;
        examinations should be considered when there is evidence of hematopoietic recovery. If&#xD;
        multiple bone marrow examinations are performed, the last examination will be used to&#xD;
        classify the patient's response. The final response will be determined no later than day 42&#xD;
        from the start of therapy.&#xD;
  &#xD;
        During treatment, all participants should undergo response evaluations prior to cycle 3.&#xD;
        Unless there is clear evidence of progressive disease in the blood, bone marrow aspiration&#xD;
        (BMA) is required and bone marrow biopsy is strongly encouraged. In cases with hypocellular&#xD;
        marrows (&lt;10 % cellularity), repeat bone marrow examinations should be considered when there&#xD;
        is evidence of hematopoietic recovery. If multiple bone marrow examinations are performed,&#xD;
        the last examination will be used to classify the patient's response. The final response will&#xD;
        be determined no later than day 42 from the start of the first cycle of therapy. Clinical BMA&#xD;
        should be repeated to assess response prior to cycles 3, 5 and 7 and subsequently after every&#xD;
        2 cycles of treatment and at the end of treatment for patients that initially responded.&#xD;
  &#xD;
        When a participant discontinues the study, a final visit will be conducted. Following&#xD;
        discontinuation of the study treatment, the participant will be treated according to the&#xD;
        investigator's or treating physician's discretion. After the end-of-therapy visit, patients&#xD;
        who have not progressed/relapsed or initiated subsequent anticancer therapy will be followed&#xD;
        every 3 months for response assessment for up to 3 years, until the initiation of subsequent&#xD;
        anticancer therapy, or until disease progression/relapse, whichever occurs first. All&#xD;
        patients will be followed to document the start of subsequent anticancer therapy and overall&#xD;
        survival (OS) every 3 months for up to 3 years after discontinuation of study drug. If a&#xD;
        participant discontinues from the study due to an adverse event considered related to study&#xD;
        treatment, a follow-up visit should be conducted no later than 30 days after the last dose of&#xD;
        protocol therapy. Safety assessments are recommended at least every 14 days, until all&#xD;
        toxicities resolve, return to baseline or become clinically satisfactory, stable, or are&#xD;
        considered irreversible.&#xD;

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.'&#xD;
  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.&#xD;
  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).&#xD;
  The three cycles are approximately 28 days each in duration.</description>

  This is a Phase 1 study investigating the safety and efficacy of Danvatirsen as a monotherapy
        followed by combination with Venetoclax in patients with relapsed/refractory myelodysplastic
        syndromes (MDS) or acute myeloid leukemia (AML). [(FDA OOPD)]
  This is a Phase 1 study investigating the safety and efficacy of Danvatirsen as a monotherapy
        followed by combination with Venetoclax in patients with intermediate/high/very high
        myelodysplastic syndromes (MDS) as determined by revised International Prognostic Scoring
        System (IPSS-R) or acute myeloid leukemia (AML) who have relapsed or are refractory to
        frontline therapy. Danvatirsen is a next generation, high affinity, antisense oligonucleotide
        inhibitor of signal transducer and activator of transcription 3 (or STAT3) that has shown
        preclinical activity in vitro and good intracellular uptake in vivo in primary patient MDS
        and AML stem cells. STAT3 is a transcription factor that is overexpressed and dysregulated in
        several malignancies. Venetoclax is a commercially available, potent, selective small
        molecule inhibitor of B-cell Lymphoma-2 (BCL-2), an anti-apoptotic protein found on some
        types of cancer cells. Prior studies have demonstrated a strong correlation between STAT3 &
        Myeloid cell leukemia-1 (MCL-1) overexpression. MCL-1 is a multi-domain anti-apoptotic
        protein belonging to the BCL-2 family, which regulates the intrinsic apoptosis pathways and
        plays a central role in mediating therapeutic resistance to novel therapies such as
        Venetoclax in MDS and AML.
  
        While FDA approved therapies have moved the field forward in newly diagnosed AML,
        relapsed/refractory (R/R) MDS and R/R AML continue to have a dismal prognosis, with a median
        overall survival of 4-10 months.
  
        The study team has designed an innovative clinical trial to study Danvatirsen as monotherapy
        followed by combination with venetoclax for the treatment of relapsed/refractory high-risk
        MDS/AML. The study team plans to incorporate several important pharmacodynamic endpoints that
        will provide a real-time assessment of the effect of STAT3 inhibition in MDS/AML stem &
        progenitor cells and the impact on target gene expression. These correlative studies will
        help identify subsets of patients that are most likely to respond to STAT3 inhibition.
        Although direct targeting and monitoring of aberrant stem cells has recently gained some
        traction in AML, it is a novel approach for the treatment of MDS.
  
        This study has been designed as a Phase 1 dose-escalation protocol of 2 different sub-studies
        to evaluate the safety profile, determine the Maximum Tolerated Dose (MTD) of Danvatirsen
        monotherapy followed by combination with Venetoclax once safety of Danvatirsen monotherapy is
        established. Patients with intermediate/high/very high IPSS-R MDS or AML who have relapsed/or
        are refractory to all available frontline therapy with no FDA approved treatment options will
        be enrolled in both the sub-studies. The objective of determining the MTD is to be able to
        find the minimum safe and biologically effective dose to be the recommended Phase 2 dose. For
        both the sub-studies safety, efficacy and assessment of PK/PD will be used to inform the
        recommended phase 2 dose.
  
        Arms/Groups are detailed in the 'Arms/Groups' module of this record. Dose-escalation for each
        substudy is as follows:
  
        Substudy 1 (Danvatirsen Monotherapy): The maximum number of patients to be enrolled in
        dose-escalation phase for Danvatirsen monotherapy is 12, and patients will be treated in
        cohorts of 3. Based upon study parameters for Bayesian Optimal Interval (BOIN) design with a
        target Dose Limiting Toxicity (DLT) rate of 25%, if the observed DLT rate at the current dose
        ≤ 0.197, the next cohort of patients will be treated at the next higher dose. If it is >
        0.298, dosing will be de-escalated to the next lower dose level. Otherwise the next cohort of
        patients will be enrolled at the current dose. Dose escalation will discontinue and the
        Maximum Tolerated Dose (MTD) will be determined: (1) once all patients have been enrolled,
        (2) 6 patients have been treated at the same dose level with the decision to stay, or (3) all
        doses are found to be too toxic. Patients not evaluable for Dose Limiting Toxicities (DLTs)
        will be replaced. The total duration of 1 cycle is approximately 4 weeks (28 days).
  
        Substudy 2 (Danvatirsen + Venetoclax Combination): Dose escalation for the combination
        therapy is as described above for the Danvatirsen monotherapy except that dose escalation
        will discontinue and Maximum Tolerated Dose (MTD) will be determined: (1) once all patients
        have been enrolled, (2) 9 patients have been treated at the same dose level with the decision
        to stay, or (3) all doses are found to be too toxic. The total duration of 1 cycle is again
        approximately 4 weeks (28 days).
  
        Dose Modifications (referenced in 'Arms/Groups'):
  
        Dose modification guidelines apply to both sub-studies and are minimal recommendations.
        Further reductions are permitted based on PI's clinical judgment following Sponsor approval.
  
        In general, in the event of ≥ Grade 3 hematological toxicities, laboratory values should be
        monitored weekly (or more frequently until ≤ Grade 2).
  
        Proposed dose modifications for treatment related toxicity (hematological) Worst Toxicity
        (CTCAE V5.0 Grade Recommended Dose Modification) Thrombocytopenia: Grade 4 (Platelet <
        25,000/mm3) Dose delay until resolved to ≤ Grade 2
  
          -  If resolved to ≤ Grade 2 in ≤ 7 days, then maintain dose level
  
          -  If resolved to ≤ Grade 2 in > 7 but ≤ 21 days, then lower 1 dose level
  
          -  Permanently discontinue treatment if not resolved to ≤ Grade 3 in 21 days.
  
        Proposed dose modifications for treatment related toxicity (non-hematological) Worst Toxicity
        (CTCAE V5.0 Grade Recommended Dose Modification) Grade 2: Dose delay until ≤ Grade 1 or
        baseline and maintain dose level Grade 3: Dose delay until resolved to ≤ Grade 1 or baseline
  
          -  If resolved in ≤ 7 days, then maintain dose level
  
          -  If resolved in > 7 days but ≤ 14 days, then lower 1 dose level
  
          -  If not resolved in ≤ 14 days, then permanently discontinue treatment Grade 4 :
             permanently discontinue treatment
  
        Danvatirsen dose reductions Dose reduction for toxicity is allowed to one dose level below
        the current level. For the lowest dose of 1 mg/kg, dose reduction is allowed to 0.5 mg/kg
        below that dose level. Once a dose has been reduced for a given patient due to toxicity, this
        dose should be administered for all subsequent infusions, unless a further dose reduction is
        required. Any subsequent dose re-escalation would require consultation with the PI. Up to 1
        dose level reduction is permitted.
  
        Venetoclax Dose Modifications:
  
        During cycle 1, venetoclax will be dose escalated daily to the goal dose. Patients will
        receive 100mg on Day 1, 200mg on Day 2 and 400mg on Day 3 and onwards, or adjusted dose per
        venetoclax label if on concomitant azoles. The goal is to administer 28 days of venetoclax in
        cycle 1 unless marrow remission with concomitant marrow hypocellularity and/or
        myelosuppression is confirmed earlier than cycle 1 Day 28. In this case the venetoclax may be
        stopped earlier to avoid venetoclax related myelosuppression or further marrow hypo/aplasia
        after discussion and approval from the PI.
  
        Initial response assessment will occur after 21 days of study therapy. Participants with
        stable or responding disease may continue on study until completion of study if their
        treating physician and PI feel that they are deriving clinical benefit. Participants with
        significant AEs or progressive disease or those having absence of clinical benefit after 6
        cycles of treatment should be removed from study. Duration of therapy will depend on
        individual response, evidence of disease progression and tolerance. In the absence of
        significant adverse events, treatment may continue indefinitely or until one of the following
        criteria applies:
  
          -  Disease progression
  
          -  Intercurrent illness that prevents further administration of treatment
  
          -  Unacceptable adverse event(s)
  
          -  Participant decides to withdraw from the study OR
  
          -  General or specific changes in the participant's condition or compliance render the
             participant unacceptable for further treatment in the opinion of the treating
             investigator.
  
        All participants should undergo response evaluations between Day 21 and Day 42 of first
        and/or second induction course (optional). Unless there is clear evidence of progressive
        disease in the blood, bone marrow aspiration is required and bone marrow biopsy is strongly
        encouraged. In cases with hypocellular marrows (<10% cellularity), repeat bone marrow
        examinations should be considered when there is evidence of hematopoietic recovery. If
        multiple bone marrow examinations are performed, the last examination will be used to
        classify the patient's response. The final response will be determined no later than day 42
        from the start of therapy.
  
        During treatment, all participants should undergo response evaluations prior to cycle 3.
        Unless there is clear evidence of progressive disease in the blood, bone marrow aspiration
        (BMA) is required and bone marrow biopsy is strongly encouraged. In cases with hypocellular
        marrows (<10 % cellularity), repeat bone marrow examinations should be considered when there
        is evidence of hematopoietic recovery. If multiple bone marrow examinations are performed,
        the last examination will be used to classify the patient's response. The final response will
        be determined no later than day 42 from the start of the first cycle of therapy. Clinical BMA
        should be repeated to assess response prior to cycles 3, 5 and 7 and subsequently after every
        2 cycles of treatment and at the end of treatment for patients that initially responded.
  
        When a participant discontinues the study, a final visit will be conducted. Following
        discontinuation of the study treatment, the participant will be treated according to the
        investigator's or treating physician's discretion. After the end-of-therapy visit, patients
        who have not progressed/relapsed or initiated subsequent anticancer therapy will be followed
        every 3 months for response assessment for up to 3 years, until the initiation of subsequent
        anticancer therapy, or until disease progression/relapse, whichever occurs first. All
        patients will be followed to document the start of subsequent anticancer therapy and overall
        survival (OS) every 3 months for up to 3 years after discontinuation of study drug. If a
        participant discontinues from the study due to an adverse event considered related to study
        treatment, a follow-up visit should be conducted no later than 30 days after the last dose of
        protocol therapy. Safety assessments are recommended at least every 14 days, until all
        toxicities resolve, return to baseline or become clinically satisfactory, stable, or are
        considered irreversible.
  allocation: Non-Randomized
  intervention model: Parallel Assignment
  primary purpose: Treatment
  masking: None (Open Label)
  measure: 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
  description: 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.
  measure: Duration of Response
  time frame: Up to 3 years after discontinuation of study treatment; up to 3.5 years total
  description: 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
  measure: Event-free survival
  time frame: Up to 3 years after discontinuation of study treatment; up to 3.5 years total
  description: 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
  measure: Overall Survival
  time frame: Up to 3 years after discontinuation of study treatment; up to 3.5 years total
  description: Overall Survival (OS) will be measured as the number of days from the date of treatment initiation until the date of death

  arm group label: Danvatirsen Monotherapy
  arm group type: Experimental
  description: 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)
  arm group label: Danvatirsen + Venetoclax Combination Therapy
  arm group type: Experimental
  description: 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.
