Description of intervention(s) / exposure
Treatment: Drugs - GSK2879552
Treatment: Drugs - ATRA
Experimental: Dose Escalation Phase (Part 1) - The safety and PK/PD data will be reviewed prior to the dose decision, and the dose escalation will be guided by the Neuenschwander -continuous reassessment method (N-CRM).The dose escalation will complete when RP2D is determined. The RP2D will be the MTD or a lower dose that provides adequate PK exposure and biologic activity with superior tolerability.
Experimental: Expansion Phase (Part 2) - Once the MTD and/or RP2D has been determined in Part 1, an expansion cohort of up to 30 subjects will be enrolled in order to characterize the clinical activity and safety profile of the RP2D. Subjects may continue treatment in the study until disease progression, unacceptable toxicity, or withdrawal of consent.
Treatment: Drugs: GSK2879552
GSK2879552 capsules contain 0.25 mg, 0.5 mg, 2 mg or 5 mg of GSK2879552 as parent. The initial dosing regimen will be continuous oral daily dosing.
Treatment: Drugs: ATRA
ATRA (Tretinoin) will be supplied as a 10 mg capsule for oral administration. The initial dosing regimen will be continuous oral twice daily dosing

An AE is any untoward medical occurrence in a clinical investigation participant, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. SAE is defined as any untoward medical occurrence that, at any dose results in death, is life threatening, requires hospitalization or prolongation of existing hospitalization, results in disability, is a congenital anomaly/ birth defect, other situations and is associated with liver injury or impaired liver function.

excluded.
- Subjects >= 60 years of age with AML who are not candidates for or have refused
standard chemotherapy.

if a minimum of 3 months has elapsed from the time of transplant and the subject has
recovered from transplant-associated toxicities prior to the first dose of GSK2879552.
- Subjects with a history of allogeneic stem cell transplant are eligible for study
participation provided the following eligibility criteria are met: transplant was >60
days prior to study enrolment; subject has not taken immunosuppressive medications for
at least 1 month; no signs or symptoms of graft versus host disease other than Grade 1
skin involvement; no active infection.
- Eastern Cooperative Oncology Group (ECOG) performance status of 0-1.
- Subjects must be stable and, in the opinion of the investigator, be expected to
complete 4 week treatment period.
- 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.
- 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 (GSK2879552 mono therapy) or 30 days (combination with ATRA),
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.

virus (HCV) infections at the time of screening. Subjects with laboratory evidence of
HCV clearance may be enrolled.
- History of or concurrent malignancy of solid tumours, except: subjects who have been
disease-free for 5 years, or subjects with a history of completely resected
non-melanoma skin cancer or successfully treated in situ carcinoma are eligible.
Subjects with second malignancies that are indolent or definitively treated may be
enrolled even if less than 5 years have elapsed since treatment. Consult
GlaxoSmithKline (GSK) Medical Monitor if unsure whether second malignancies meet
requirements specified above.
- Currently receiving cancer therapy. Hydroxyurea will be allowed.
- Received major surgery, radiotherapy, or immunotherapy within 4 weeks of GSK2879552
administration.

- Prior treatment with poly ADP ribose polymerase (PARP) inhibitors (eg., olaparib,
ABT-888)
- Baseline Montreal Cognitive Assessment (MOCA) score of 22 or lower
- Evidence of severe or uncontrolled systemic diseases. Any serious and/or unstable
pre-existing medical, 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.
- Patients at risk of non-AML related major bleeding (e.g. recent gastrointestinal [GI]
hemorrhage or neurosurgery).
- Symptomatic or untreated central nervous system (CNS) leukemia. Subjects are permitted
to enroll if previously treated for CNS disease, free of symptoms at the time of
screening, and have not required intrathecal chemotherapy at least 1 month prior to
study Day 1.

shorter with a minimum of 14 days preceding the first dose of study treatment(s) in
this study.
- Have a known immediate or delayed hypersensitivity reaction or idiosyncrasy to drugs
chemically related to GSK2879552 or LSD1 inhibitors that contraindicates their
participation.
- Lactating female.
- Consumption of Seville oranges, grapefruit, grapefruit hybrids, grapefruit juice,
pommelos, or exotic citrus fruits, from 1 day prior to the first dose of study
treatment(s) until the last dose of study drug.
- Current use of a prohibited medication including anticoagulants or platelet inhibitors
or expected to require any of these medications during treatment with the
investigational drug.
- Previous treatment with GSK2879552 For ATRA Combination arm ONLY
- Known hypersensitivity to ATRA, parabens (preservatives in the gelatin capsule) or
other retinoids.
- ATRA capsule contains sorbitol. Subjects with rare hereditary problems of fructose
intolerance are excluded.

Summary
Brief summary
This study is a phase I, open-label study to determine recommended phase 2 dose (RP2D) and
regimen for the orally administered lysine specific demethylase 1 (LSD1) inhibitor
GSK2879552, alone or in combination with All-Trans Retinoic Acid (ATRA). The recommended dose
and regimen will be selected based on the safety, pharmacokinetic (PK), and pharmacodynamic
(PD) profiles observed after the treatment of subjects with relapsed/refractory AML. The
study consists of two parts. Part 1 will identify the maximum tolerated dose (MTD) and/or
RP2D using a dose-escalation procedure. Dose escalations will be guided by the
Neuenschwander-continual reassessment method (N-CRM). PK/PD expansion cohorts will also be
included in Part 1 to characterize the range of biologically effective doses by assessing PD
markers and obtain additional PK data. Part 2 will explore further the safety, tolerability,
and clinical activity of GSK2879552, alone or in combination with ATRA, at the RP2D in
subjects with AML.
