In Part 2A2 (add-on to Ruxo), Ruxolitinib Combo cohorts: participants must have been treated with ruxolitinib for = 6 months, and on a stable dose = 8 weeks prior to C1D1 with sub-optimal response defined as: (1) palpable spleen > 10 cm below left costal margin (LCM) on physical examination at Screening, or (2) palpable spleen 5-10 cm below LCM on physical examination at Screening and the presence of active MF symptoms at screening as measured by MFSAF (Appendix 9) and defined as 1 symptom score = 5 or 2 symptom scores = 3 each., Participant has diagnosis of PMF according to the 2017 World Health Organization criteria (Appendix 12), or diagnosis of post-ET or post-PV MF according to the IWG-MRT 2007 criteria (Appendix 13), confirmed by the most recent local pathology report., Participant has an Eastern Cooperative Oncology Group (ECOG) Performance Status (PS) = 2 at Screening., Part 1A, 1B, and 2B participants at Screening must have a DIPSS Risk Score of Intermediate-1 with symptoms, Intermediate-2, or High., Part 2A participants must have had a DIPSS Risk Score of Intermediate-2 or High, Participant has a measurable splenomegaly during the screening period as demonstrated by spleen volume of = 450 cm3 by MRI or computed tomography (CT) scan assessment., Not Applicable per Protocol Amendment 03, replaced with 10). In Part 1A- and 2A1-Ruxolitinib Combo cohorts: participants must not have been treated with JAK2 inhibitors prior to the start of treatment with BMS- 986158 in combination with ruxolitinib.

•Participant with previous splenectomy., 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., 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)., Participants with uncontrolled endocrine disorder including thyroid disease or inadequate thyroid function. Note: Subclinical hypothyroidism (thyroid-stimulating hormone< 10 mIU/mL) or controlledhypothyroidism on appropriate thyroid supplementation are acceptable. Physical and Laboratory Test Findings a) Absolute neutrophil count< 1.0 × 109/L b) Hgb < 8 g/dL (Screening Hgb = 14 days after last RBC transfusions)only for non-TD participants) c) WBC count > 100 × 109/L d) Myeloblasts = 10% in peripheral blood e) AST and ALT = 3.0 × upper limit of normal (ULN) f) Serum amylase or lipase > 1.5 × ULN g) Serum total bilirubin = 1.5 × ULN (participant's total bilirubin between 1.5 to 3.0 × ULN are eligible if the direct bilirubin fraction is < 25% of the total bilirubin) h) Creatinine clearance (CrCl) < 50 mL/min (calculated using the Cockroft-Gault formula) within 14 days prior to first dose of study treatment. i) Serum albumin < 3.0 g/dL j) Participant with abnormal blood coagulation parameters: Prothrombin time (PT) such that international normalized ratio (INR) is > 1.5 × ULN or a partial thromboplastin time > 1.2 × ULN. k) PLT < 100 × 109/L for participants in the ruxolitinib cohorts Parts 1A and 2A1, and PLT < 75 × 109/L for participants in fedratinib cohorts Parts 1B and 2B (combination and monotherapy arms), for participants in the ruxolitinib cohort Part 2A2 (add-on to Ruxo) and Part 2A3 (only if PLT is not > 99 × 109/L) (Screening PLT = 7 days after last PLT transfusions)., In Part 1B-Fedratinib Combo cohorts, Part 2B1-Fedratinib Combo arm, and Part 2B2- BMS-986158 Mono arm: a) Participant with prior history of encephalopathy including WE. b) Participant with thiamine deficiency, defined as thiamine levels in whole blood below normal range according to institutional standard and not corrected prior to enrollment on the study (ie, C1D1). c) Participant who received ruxolitinib within 14 days prior to starting the treatment with BMS-986158 alone or in combination with fedratinib. 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., Participant with previous exposure to a BET inhibitor., Prior organ allograft or allogenic hematopoietic stem cell transplantation., Participant with diagnosis of chronic liver disease (eg, chronic alcoholic liver disease, autoimmune hepatitis, sclerosing cholangitis, primary biliary cirrhosis, hemochromatosis, non-alcoholic steatohepatitis)., Participant has impaired cardiac function or clinically significant cardiac diseases a) Any of the following on 12-lead E
