Description of intervention(s) / exposure

Treatment: Drugs - GSK525762

Experimental: Part 1: GSK525762 QD Cohort - Subject will be administered a 5 milligram (mg) starting dose of GSK525762, oral tablets, QD. Dose escalations will be performed in Part 1 and dose adjustments are allowed to address tolerability and safety issues. Thereafter, subjects will be enrolled in a standard 3+3 design. Separate dose escalation cohorts will be opened for subjects with AML, NHL, and MM for QD dosing. Dose escalation will continue until an MTD is determined or until a dose of 200 mg per day is reached.

Experimental: Part 1: GSK525762 BID Cohort - Subject will be administered a starting dose of GSK525762, oral tablets, 20 mg BID (12 hours apart, total daily dose of 40 mg). Dose escalations will be performed in Part 1 and dose adjustments are allowed to address tolerability and safety issues. Thereafter, subjects will be enrolled in a standard 3+3 design. Separate dose escalation cohorts will be opened for subjects with AML, NHL, and MM, for BID dosing. Dose escalation will continue until an MTD is determined or until a dose of 200 mg per day is reached.

Experimental: Part 2: GSK525762 dose expansion cohort - After the MTD has been determined in Part1, Part 2 dose expansion cohorts will be opened for AML, NHL and MM.

Treatment: Drugs: GSK525762
GSK525762 1 mg, 10 mg and 30 mg will be supplied as white to off-white, amorphous free base and white to slightly colored crystalline besylate tablets, round, biconvex tablets with no markings. GSK525762 will be administered with 240 milliliter (mL) water.

* In Part 1 and, Part 2, subjects must have AML, MM, or NHL. Subjects with AML, are eligible if they • have relapsed and/or refractory disease, OR are>=65 years of age and not candidates for or have refused standard chemotherapy. Subjects with multiple myeloma are eligible if they have progressed despite therapy with an alkylating agent, proteasome inhibitor, and immunomodulatory agent, either as individual regimens or in combination. Subjects with NHL are eligible if they have received at least two prior lines of systemic therapy, including at least one line of immunochemotherapy with an anti-CD20 antibody (if their tumor expresses CD20).

In Part 2, the NHL cohort will separately enrol subjects with double- and triple hit lymphoma, so that a minimum of 10 subjects with this subset of disease will be enrolled. To be eligible for this sub-cohort, tumor sample from the subject must demonstrate rearrangement and/or overexpression of MYC and either BCL2 and/or BCL6 genes. Evaluation of double- or triple-hit status may be performed via appropriate local testing, and the determination of double- or triple-hit diagnosis will be at the discretion of the investigator and GSK Medical Monitor.

* Subjects with a prior history of stem cell transplant (autologous and/or allogeneic) are allowed if

* At least 3 months has elapsed from the time of transplant and
* the subject has recovered from transplant-associated toxicities prior to the first dose of GSK525762, and For subjects with a prior history of allogeneic transplant,
* the subject has been off systemic immunosuppressive medications (including but not limited to: cyclosporine, tacrolimus, mycophenolate mofetil, or corticosteroids) for at least 1 month prior to the first dose of GSK525762. Topical steroids are permitted
* there are no signs or symptoms of graft versus host disease, other than Grade 1 skin involvement.
* Eastern Cooperative Oncology Group (ECOG) performance status of <=1.
* Subject must be stable enough to be expected to complete dosing through the DLT observation period as assessed by 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.
* A female subject is eligible to participate if she is of: Non-childbearing potential defined as pre-menopausal females with a documented tubal ligation or hysterectomy; or postmenopausal defined as 12 months of spontaneous amenorrhea [in questionable cases, a blood sample with simultaneous follicle stimulating hormone (FSH) > 40 milli-International units per milliliter and estradiol < 40 picograms per milliliter (< 140 picomole per liter) is confirmatory]. Females on hormone replacement therapy (HRT) and whose menopausal status is in doubt will be required to use one of the contraception methods defined in protocol if they wish to continue their HRT during the study. Otherwise, they must discontinue HRT to allow confirmation of post-menopausal status prior to study enrolment. For most forms of HRT, at least two to four weeks will elapse between the cessation of therapy and the blood draw; this interval depends on the type and dosage of HRT. Following confirmation of their post-menopausal status, they can resume use of HRT during the study without use of a contraceptive method; Child-bearing potential and agrees to use one of the contraception methods for an appropriate period of time (as determined by the product label or investigator) prior to the start of dosing to sufficiently minimize the risk of pregnancy at that point. Female subjects must agree to use contraception until at least 7 months after the last dose of study medication; Negative serum pregnancy test <= 7 days prior to first study drug dose; Female subjects who are lactating must discontinue nursing prior to the first dose of study treatment and must refrain from nursing throughout the treatment period and for 5 half-lives of GSK525762 or at least 28 days (whichever is longer) following the last dose of study treatment.
* Male subjects must agree to use one of the methods of contraception specified.

* Current use of a prohibited medication or requires any of these medications during treatment with the investigational drugs. This includes excluding current medications known or suspected to be associated QT prolongation. In addition, any subject who is expected to require a QT prolonging medication while on trial should not be enrolled.
* Evidence of severe or uncontrolled systemic diseases (e.g., unstable or uncompensated respiratory, hepatic, renal, cardiac disease, or clinically significant bleeding episodes). 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.
* Symptomatic or untreated Central nervous system (CNS) disease, Subjects with a history of CNS disease (leukemia, lymphoma or myeloma) are permitted to enrol if they have previously received appropriate therapy and CNS remission has been documented. Subject with primary CNS lymphoma (defined as isolated CNS lymphoma without systemic involvement) are excluded from study.
* Cardiac abnormalities as evidenced by any of the following: History or current clinically significant uncontrolled arrhythmias or hypertension; Clinically significant conduction abnormalities or arrhythmias, subjects with Bundle Branch Block; Presence of cardiac pacemaker; 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.
* Any of the following ECG findings or assessments including: Baseline QTcF interval >=450 milliseconds; Clinically significant ECG assessments should be reviewed by the site cardiologist prior to study entry.
* GSK525762 is a benzodiazepine class molecule. Any serious known immediate or delayed hypersensitivity reaction(s) to GSK525762 or idiosyncrasy to drugs chemically related to the investigational drug.
* Evidence of hemoptysis within the last 7 days.
* History of major gastrointestinal bleeding within the last 3 months or any evidence of active gastrointestinal bleeding excludes the subject.

Summary

Brief summary

This is an open-label repeat dose, multicenter, 2-part study to determine the maximum tolerated dose (MTD) and the recommended Phase 2 dose (RP2D) for GSK525762 given once-daily (QD) orally. Part 1 of the study is a dose escalation phase to select the recommended Part 2 dose (RP2D) based on the safety, PK, and PD profiles observed after oral administration of GSK525762. Eligible subjects with select relapsed refractory hematological malignancies (acute myeloid leukemia \[AML\], non-Hodgkin's Lymphoma \[NHL\]and multiple myeloma \[MM\]), will be enrolled in the QD and/or BID dosing cohorts until a MTD is established. Subjects may continue treatment in the study until disease progression, unacceptable toxicity, or withdrawal of consent. . Upon determination of the MTD, twice daily (BID) dosing cohorts may be opened to collect additional safety data and evaluate the preliminary efficacy of GSK525762 administered BID. Part 2 will explore clinical activity at the MTD or RP2D; separate expansion cohorts will be planned for acute myeloid leukemia (AML), non-Hodgkin's Lymphoma (NHL, including an exploratory sub-cohort of subjects with myc and B-Cell Leukemia (BCL)2 and/or BCL6 rearrangements/overexpression \[double- and triple-hit lymphoma\]), and multiple myeloma (MM). This is the first study of this agent to be conducted in subjects with these relapsed and/or refractory hematological malignancies for which no standard therapies are anticipated to result in a durable remission.
