Description of intervention(s) / exposure
Treatment: Drugs - Part 1; Cohort 1
Treatment: Drugs - Part 1; Cohort 2
Treatment: Drugs - Part 2; Stage 1
Treatment: Drugs - Part 2, Stage 2

Experimental: GSK2110183 - The oral dose of GSK2110183 the subjects received will be dependent on when the subject is enrolled to the study. GSK2110183 will be provided in 25mg and 50mg capsules containing the hydrochloride salt form of the API, microcrystalline cellulose, magnesium stearate, and microcrystalline cellulose (optional). They are filled into hard gelatin capsules. The 25mg tablets are opaque, swedish orange, size 2 capsules with no external markings, filled with a white powder. The 50mg tablets are opaque, white, size 1 capsules with no external markings, filled with a white powder.

Other: Bortezomib - Bortezomib salvage therapy will be administered as a 3 to 5 second intravenous (IV) push at 1.3 mg/m2 on Days 1, 8, and 15 in each 21-day cycle until one of the Treatment Discontinuation Criteria is met.


Treatment: Drugs: Part 1; Cohort 1
On Cycle 0, Day -3, three subjects will be enrolled to receive a single oral dose of 125mg GSK2110183. After the 72 hour PK sampling is completed, the subjects will continue the 125mg GSK2110183 dose daily for 21 day cycles. If none of the 3 subjects experience one of the DLTs listed in the protocol during Cycle 1, the dose will be escalated to 150mg GSK2110183 for the subject enrolled to Cohort 2. Alternately, if 1 subject reports a DLT, then 3 more subjects will be enrolled at the same dose. If 2 of 6 subjects report a DLT, then the MTD has been exceeded. Subjects will remain on study until they meet one of the Treatment Discontinuation Criteria.

Treatment: Drugs: Part 1; Cohort 2
For Cohort 2, on Cycle 0, Day -3, three subjects will be enrolled to receive a single oral dose of 150mg GSK2110183. After the 72 hour PK sampling is completed, the subjects will continue the 150mg GSK2110183 dose daily for 21 day cycles. If none of the 3 subjects experience one of the DLTs listed in the protocol during Cycle 1, the MTD will be determined unless the PK and Pharmacodynamic data indicates another dose level should be evaluated. Alternately, if 1 subject reports a DLT, then 3 more subjects will be enrolled at the same dose. If 2 of 6 subjects report a DLT, then the MTD has been exceeded. Subjects will remain on study until they meet one of the Treatment Discontinuation Criteria.

Treatment: Drugs: Part 2; Stage 1
Following the completion of PK sampling and the determination of a Recommended Phase 2 Dose (RP2D) of GSK2110183 in Cohorts 1 and 2, subjects will be enrolled into Part 2, Stage 1 of the study. Twenty subjects will be enrolled in Stage 1. If no subject responds, the study will be stopped; otherwise, the study will continue enrollment of Stage 2.

Treatment: Drugs: Part 2, Stage 2
Twenty subjects will be enrolled in Part 2, Stage 2. If 4 or fewer of the 40 subjects (Stages 1 and 2) respond, the study will not be deemed as a success for GSK2110183 monotherapy. However, those subjects meeting the criteria for progression (as defined by IMWC Panel 1) who also meet the additional eligibility criteria for salvage therapy may proceed to GSK2110183 + bortezomib salvage therapy. GSK2110183 + bortezomib salvage therapy will be continued until one of the Treatment Discontinuation Criteria is met

Eligibility
Key inclusion criteria
* Capable of giving written informed consent, which includes compliance with the requirements and restrictions listed in the consent form.
* Male or female who is at least 18 years of age or older.
* Histologically confirmed diagnosis of secretory MM (must have measurable M protein in serum or urine) with one or more of the following:

Serum M-protein count greater than or equal to 1 g/dL Urinary M-protein greater than or equal to 200 mg/24 hours Serum free light chain (FLC) assay: involved FLC level greater than or equal to 10 mg/dL (greater than or equal to 100 mg/L) and a serum FLC ratio outside of normal range. Biopsy proven plasmacytoma

* Relapsed after 2 or more lines of systemic therapy including at least one proteasome inhibitor (i.e., bortezomib, carfilzomib) and at least one immunomodulatory agent (i.e., lenalidomide, pomalidomide) AND refractory to proteasome inhibitor therapy. Subjects will be considered refractory to proteasome inhibitor therapy if they experienced stable disease or progressive disease as the best response on their last proteasome inhibitor containing therapy OR progressed within 60 days following two or more cycles of proteasome inhibitor therapy. A line of therapy is generally separated by disease progression from a preceding line of therapy; therefore, the preparative regimen (with or without total body irradiation) and subsequent autologous stem cell rescue used for an autologous stem cell transplant are considered as one line of therapy.
* Subjects with a history of autologous stem cell transplant are eligible for study participation provided the following eligibility criteria are met:

Transplant was more than 100 days prior to study enrolment No active infection Subject meets the remainder of the eligibility criteria

* Performance status score of 0 to 2 according to Eastern Cooperative Oncology Group (ECOG).
* Able to swallow and retain oral medication.
* Fasting serum glucose less than126 mg/dL (<7 mmol/L). Subjects diagnosed previously with diabetes mellitus type 2 must also meet the additional following criteria:

Diagnosis of diabetes greater than 6 months prior to enrollment Glycosylated hemoglobin A1c (HbA1c) less than 8% at screening

* A female subject is eligible to participate if she is of the following:

Non-childbearing potential (i.e., physiologically incapable of becoming pregnant) defined as premenopausal 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 greater than 40 MlU/ml and estradiol less than 40 pg/ml (less than 147 pmol/L) 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 listed in the 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 enrollment. For most forms of HRT, at least 2 to 4 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.

Childbearing potential, has a negative serum pregnancy test during the screening period, and agrees to use adequate contraception (methods listed in the protocol) from screening until four weeks after the last dose of GSK2110183. Note: Oral contraceptives are not reliable due to potential drug-drug interaction.

* Male subjects with female partners of childbearing potential must have had a prior vasectomy or agree to use adequate contraception from the time of the first dose of GSK2110183 until 3 months after the last dose of GSK2110183.
* Adequate organ function as defined by laboratory results within specific value ranges listed in the protocol.

Inclusion criteria: Salvage Therapy with GSK2110183 and Bortezomib:

* Platelet count greater than or equal to 70 X 10^9/L
* A subject whose ANC is greater than 1000/mm^3 before GSK2110183 monotherapy but whose ANC decreases below 1000/mm^3 at the time of transitioning to the salvage therapy is allowed up to 14 days following interruption of GSK2110183 dosing for ANC to recover to greater than or equal to 1000/mm^3.

* Use of an investigational drug within 14 days or 5 half-lives, whichever is longer, preceding the first dose of GSK2110183.

* Current use of a prohibited medication.
* Current use of oral corticosteroids, with the exception of inhaled or topical corticosteroids.
* Anticoagulants (e.g., warfarin, low molecular weight heparin, direct thrombin inhibitors) at therapeutic doses or at low doses (e.g., prophylactic) are permitted only if the subject meets the partial thromboplastin time (PTT) and international normalization ratio (INR) entry criteria. Anticoagulant use must be monitored in accordance with local institutional practice.

* History of known human immunodeficiency virus infection.
* Subjects with a positive test for hepatitis B surface antigen or a positive test for hepatitis C antibody are excluded, regardless of the viral load. If hepatitis C antibody is positive, a confirmatory RIBA test may be performed. If the RIBA test is negative, the subject is eligible for the study.
