Primary Outcome Measures :
- Determine the incidence of dose-limiting toxicities (DLTs) at escalated doses of TP-3654 [ Time Frame: 28 days ]Frequency, severity, and causal relationship of study defined high grade toxicities
- Determine the incidence of treatment emergent adverse events [ Time Frame: 28 days ]Frequency, severity, and causal relationship of adverse events
Secondary Outcome Measures :

- Determine proportion of patients who have ≥ 35% spleen volume reduction (SVR35) at week 24 [ Time Frame: 24 weeks ]Number of patients who have ≥ 35% spleen volume reduction compared to baseline after 24 weeks of treatment
- Determine proportion of patients with ≥ 50% improvement in total symptom score (TSS50) at week 24 [ Time Frame: 24 weeks ]Number of patients who have ≥ 50% total symptom score reduction by MFSAF compared to baseline after 24 weeks of treatment
- Determine the change in Patient Global Impression of Change (PGIC) at week 24 [ Time Frame: 24 weeks ]Change in PGIC score during treatment
- Assess the reduction in bone marrow fibrosis in repeat biopsies [ Time Frame: 12 months ]Change in bone marrow fibrosis during treatment compared to baseline
- Determine Overall Survival [ Time Frame: 3 years ]The time interval from treatment start date of death from any cause
- Determine the incidence of QT interval changes and morphology as assessed by holter electrocardiogram (ECG) monitoring [ Time Frame: 25 hours ]Changes in QT interval and heart rhythm
- Establish the pharmacokinetic (PK) parameters of TP-3654 by assessing Half-life (t½) [ Time Frame: 24 hours ]The estimate of time for the TP-3654 concentration or amount to be reduced by half
- Establish the pharmacokinetic (PK) parameters of TP-3654 by assessing Peak Plasma Concentration (Cmax) [ Time Frame: 24 hours ]The maximum TP-3654 concentration after administration
- Establish the pharmacokinetic (PK) parameters of TP-3654 by assessing Time of Maximum concentration observed (tmax) [ Time Frame: 24 hours ]The estimate of time to maximum TP-3654 concentration
- Establish the pharmacokinetic (PK) parameters of TP-3654 by assessing Area under the plasma concentration versus time curve (AUC) [ Time Frame: 24 hours ]The amount of drug exposure over 24 hours period after administration
Other Outcome Measures:
- Study potential pharmacodynamic (PD) markers of TP-3654 [ Time Frame: 12 months ]Evaluate exploratory biomarkers in peripheral blood samples and bone marrow biopsy samples. Change in protein phosphorylation and inflammatory cytokines.
