Gradual tapering of ruxolitinib as per investigator’s discretion is recommended, and must be completed at the latest 14 days prior to C1D1. Use of systemic steroids = 10 mg/day prednisone or equivalent is allowed. d) Participant with previous exposure to JAK2 inhibitor(s) other than ruxolitinib. 3) Participant with previous exposure to a BET inhibitor. 4) Prior organ allograft or allogenic hematopoietic stem cell transplantation. 5) Participant with diagnosis of chronic liver disease (eg, chronic alcoholic liver disease, autoimmune hepatitis, sclerosing cholangitis, primary biliary cirrhosis, hemochromatosis, non-alcoholic steatohepatitis). 6) Participant has impaired cardiac function or clinically significant cardiac diseases: a) Any of the following on 12-lead ECG prior to study drug administration, confirmed by repeat and central ECG laboratory assessment: i) QRS ? 120 msec ii) QTcF ? 460 msec 7) Positive blood screen for hepatitis C antibody, hepatitis B surface antigen, or human immunodeficiency virus (HIV) 1 and 2 antibody a) Participants who are seropositive due to hepatitis B virus (HBV) vaccination are eligible. b) Participants who have no active viral infection and are under adequate prophylactics against HBV re-activation are eligible. c) Participants who are positive on anti-HCV IgG, but negative on viral RNA, and without morphologic changes in liver, are eligible. 8) History of medically significant thromboembolic events or bleeding diathesis within the past 6 months, such as cerebrovascular accident (including transient ischemic attacks), pulmonary embolism, pulmonary hemorrhage > 2 teaspoonfuls/24 hours or repeated pulmonary hemorrhage. 9) Ppts with current or recent (within 1 month of study drug administration) GI disease such as symptomatic or uncontrolled ulcers (gastric or duodenal), particularly those with a history of and/or risk of perforation and GI tract hemorrhages, chronic or intermittent diarrhea, or uncontrolled disorders that increase the risk of diarrhea, such as inflammatory bowel disease. Non-chronic conditions (eg, infectious diarrhea) that are completely resolved for at least 2 weeks prior to starting study treatment are not exclusionary. 10) Previous SARS-CoV-2 infection within 10 days prior to Cycle 1 Day 1 for mild or asymptomatic illness or within 20 days prior to Cycle 1 Day 1 for severe/critical illness. Note: Acute symptoms must have resolved and based on investigator assessment in consultation with the Sponsor's Medical Monitor, there are no sequelae that would place the participant at a higher risk of receiving study treatment. 11) In Parts 1A and 2A: Participant with treatment or use of pharmaceutical, herbal agents, or food known to be strong inducers of CYP3A4 within 2 week or 5 half-lives (whichever is longer), strong inhibitors of CYP3A4 or P-gp within 1 week or 5 half-lives (whichever is longer). 12) Ppts with uncontrolled endocrine disord

| Main Objective: Dose Escalation (Part 1) - To assess the safety tolerability, and to determine the MTD and/or RP2D of BMS-986158 in combination with ruxolitinib in previously untreated (1L) MF participants, and in combination with fedratinib in ruxolitinib-exposed (2L) MF participants. Dose Expansion (Part 2) - To further determine the safety and tolerability of BMS-986158 in combination with ruxolitinib in 1L or as an "add-on" to ruxolitinib in MF participants, and in combination with fedratinib, or as monotherapy, in 2L MF participants at the RP2Ds.;Secondary Objective: - To assess the preliminary efficacy of BMS-986158 in combination with ruxolitinib in 1L or as an "add-on" to ruxolitinib in MF participants or in combination with fedratinib, or as monotherapy, in 2L MF participants, based on SVR. -To assess the preliminary efficacy of BMS-986158 in Part 2A2 (add-on to ruxolitinib) participants based on SVR. - To evaluate MF-associated symptoms as measured by the MFSAF of participants treated with BMS-986158 monotherapy and in combination with either ruxolitinib or fedratinib in Part 2. - Improvement in anemia in Part 2 based on pre-defined changes in both TI participants and TD participants. - To characterize the PK of BMS-986158 in combination with ruxolitinib and in combination with fedratinib and in monotherapy - SDPFS of participants treated with BMS-986158 in combination with either ruxolitinib or fedratinib and in monotherapy.;Primary end point(s): •Incidence of AEs, SAEs, AEs meeting protocol-defined DLT criteria, AEs leading to discontinuation, and death. •Incidence of AEs, SAEs, AEs leading to discontinuation, and death. ;Timepoint(s) of evaluation of this end point: up to progressive disease, but it is expected to last from 12 months up to 24 months + 30-90 days. = up to 27 months | — |
