Safety, Clinical Activity, Pharmacokinetics (PK) and Pharmacodynamics Study of GSK2879552, Alone or With Azacitidine, in Subjects With High Risk Myelodysplastic Syndromes (MDS)

Stopped early · Phase 1/Phase 2

Conditions studied: Myelodysplastic Syndrome, Myelodysplastic Syndromes

In brief

This is a Phase I/II, open-label, 2 arm study to evaluate the safety and clinical activity of GSK2879552 alone, or in combination with azacitidine in subjects with MDS. The study consisted of 2 parts. The objective of Part 1 is to determine the recommended phase 2 dose (RP2D) of GSK2879552 administered alone and in combination with azacitidine in adult subjects with high risk MDS previously treated with HMA. The objective of Part 2 is to evaluate clinical activity after treatment with GSK2879552, alone or in combination with azacitidine, in adult subjects with high risk MDS previously treated with HMA.

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• >=18 years of age and provided signed written informed consent
• Subjects must have IPSS-R high or very high risk myelodysplastic syndromes (MDS) by World Health Organization (WHO) classification
• Subjects must have failed hypomethylating treatment where "failure" is defined as: Progression (according to 2006 International Working Group [IWG] criteria) at any time after initiation of the hypomethylating treatment OR Failure to achieve complete or partial response or hematological improvement (HI) (according to 2006 IWG) after at least 4 cycles treatment OR Relapse after initial complete or partial response or HI (according to 2006 IWG criteria).
• Subjects are not a candidate, or have failed allogeneic stem cell transplantation. Subjects who underwent allo-transplant in the past are eligible under following conditions: transplant was >2 year prior to enrolment, and no evidence of active graft-versus-host disease (GVHD)
• Eastern Cooperative Oncology Group (ECOG) performance status of 0-1.
• Subjects must have a life expectancy of at least 12 weeks, in the opinion of the investigator.
• Able to swallow and retain orally administered medication and does not have any clinically significant gastrointestinal abnormalities that may alter absorption such as malabsorption syndrome or major resection of the stomach or bowels.
• All prior treatment-related toxicities must be National Cancer Institute- Common Toxicity Criteria for Adverse Events (NCI-CTCAE), version 4.0 <=Grade 1 at the time of enrollment (except for alopecia).
• Adequate baseline organ function defined by: International Normalization Ratio (INR) and activated partial thromboplastin time (aPTT) <=1.3xupper limit of normal (ULN); platelet count (PLT) >=10,000 (transfusions permitted to bring PLT to >10,000); total bilirubin <=1.5xULN (Isolated bilirubin >1.5xULN is acceptable if bilirubin is fractionated and direct bilirubin <35% or subject has a diagnosis of Gilbert's syndrome); Alanine transaminase (ALT) <=2.5xULN; creatinine <=1.5xULN OR calculated creatinine clearance by Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation or measured from 24 hour urine >=50 milliliters (mL)/minute (min); and Ejection fraction >=lower limit of normal (LLN) by Echocardiogram (ECHO) or multigated acquisition scan (MUGA)
• Women of childbearing potential must have a negative serum pregnancy test within 7 days of first dose of study treatment and agree to use effective contraception during the study and for 7 days following the last dose of study treatment.
• Men with a female partner of childbearing potential must have either had a prior vasectomy or agree to use effective contraception from the administration of the first dose of study treatment until 3 months after the last dose of study treatment to allow for clearance of any altered sperm.

You may not qualify if…

• Evidence of severe or uncontrolled systemic diseases (e.g., severe/chronic infection, unstable or uncompensated respiratory, renal, or cardiac disease). Any serious and/or unstable pre-existing medical (aside from malignancy exception above), psychiatric disorder, or other conditions that could interfere with subject's safety, obtaining informed consent or compliance to the study procedures, in the opinion of the Investigator
• Current active liver or biliary disease (with the exception of Gilbert's syndrome or asymptomatic gallstones or otherwise stable chronic liver disease per investigator's assessment)
• Patients with any major bleeding current or within the past 4 weeks. (e.g. recent gastrointestinal [GI] hemorrhage or neurosurgery).
• Administration of an investigational drug within 14 days or 5 half-lives, whichever is shorter, preceding the first dose of study treatment(s) in this study.
• Cardiac abnormalities as evidenced by any of the following: clinically significant uncontrolled arrhythmias or uncontrolled hypertension; history or evidence of current >=Class II congestive heart failure as defined by New York Heart Association (NYHA); history of acute coronary syndromes (including unstable angina and myocardial infarction), coronary angioplasty, or stenting within the past 3 months; baseline Corrected QT (QTc) interval using Fridericia's formula >450 milliseconds (msec) or >480 msec in subjects with Bundle Branch Block.
