| Main Objective: Part I. To determine the recommended phase 2 dose (RP2D) of GSK2879552 administered alone and in combination with azacitidine in adult subjects with HR MDS previously treated with HMA. Part II. To evaluate clinical activity after treatment with GSK2879552, alone or in combination with azacitidine, in adult subjects with HR MDS previously treated with HMA.;Secondary Objective: PartI. 1. To evaluate clinical activity after treatment with GSK2879552, alone or in combination with azacitidine, in adult subjects with HR MDS previously treated with HMA. 2. To measure the exposure to GSK2879552 alone and to GSK2879552 and azacitidine in combination, in patients with HR MDS previously treated with HMA. 3. To evaluate duration of response, duration of clinical benefit, progression-free survival and overall survival. 4. To evaluate frequency and time to progression to AML (per 2006 IWG criteria). 5. To evaluate platelet and RBC transfusion dependence Part II. 1. To further evaluate the safety and tolerability of GSK2879552 administered alone or in combination with azacitidine. 2. To characterize the population PK of GSK2879552, alone or in combination with azacitidine in patients with HR MDS previously treated with HMA. 3. To evaluate duration of response, duration of clinical benefit, progression-free survival, and overall survival. Please see protocol;Primary end point(s): Part 1: AEs, SAEs, dose limiting toxicities, dose reductions or delays, withdrawals due to toxicities and changes in safety parameters (e.g., laboratory values, vital signs, electrocardiograms [ECGs], physical examinations). Part 2: Clinical benefit rate (CBR) defined as % of subjects achieving CR, mCR, PR, cytogenetic response, HI or SD. Objective response rate (ORR) defined as % of subjects achieving CR, mCR, PR, cytogenetic response, or HI [as per 2006 IWG criteria]).;Timepoint(s) of evaluation of this end point: AEs/SAEs are evaluated throughout the trial at each visit.
