  • Performance Status score of 0 or 1 according to the Eastern Cooperative Oncology Group (ECOG) scale.
  • Able to swallow and retain oral medication.
  • Must agree to collection of blood samples for the evaluation of circulating free DNA (cfDNA) (Part 1B or Part 2).
  • 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] greater than 40 MlU/ml and estradiol less than 40 pg/ml [less than 140 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 in Section 8.1.1 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.
  • Child-bearing potential and agrees to use one of the contraception methods listed in Section 7.3.2 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. Additionally, women of child-bearing potential must have a negative serum pregnancy test within 14 days prior to the first dose of study medication. Female subjects must agree to use contraception until four weeks after the last dose of study medication.
  • Note: Oral contraceptives are not reliable due to potential drug-drug interaction and should only be used in combination with the alternative methods outlined in Section 8.1.1.
  • Male subjects must agree to use one of the contraception methods listed in Section 8.1.2. This criterion must be followed from the time of the first dose of study medication until four months after the last dose of study medication.

  • Histologically- or cytologically-confirmed diagnosis of one of the following:
  • Triple negative (estrogen receptor(ER)-/ progesterone receptor(PR)-/ human epidermal growth factor receptor 2 (HER2)) breast cancer in the locally advanced or metastatic setting BRAF-wild type melanoma. Based on emerging data, subjects with these tumor histologies may be required to meet specific genetic selection criteria if those criteria are felt to improve the likelihood that a given subject will respond to study drug(s). If this is to occur, the site and the Investigational Review Board (IRB) will be notified but this change will not constitute a protocol amendment.
  • Known Phosphatase and tensin homolog (PTEN) status of tumor. At least 6 of the subjects enrolled in Stage 1 with each tumor type will have PTEN deficiency while at least 6 others will be PTEN wild type.
  • If the subject's tumor PTEN status was previously determined by an acceptable, analytically validated assay (i.e., Immunohistochemistry (IHC), fluorescence in situ hybridization (FISH), sequencing, copy number analysis) then PTEN by IHC at Screening will not need to be repeated for the purpose of enrollment in this study. However, archival tumor tissue or tissue from a fresh biopsy specimen should be submitted for confirmation of PTEN status by a central laboratory using IHC.
  • If PTEN status was not previously determined, archival tissue from a previous tumor biopsy specimen must be available for PTEN IHC analysis; if archival tissue is not available or found to not contain tumor tissue, a fresh biopsy is required to obtain tumor tissue for testing.
  • Subjects in Part 2 that have been previously diagnosed with Type 2 diabetes must also meet the additional following criteria:
  • Diagnosis of diabetes greater than or equal to 6 months prior to enrolment HbA1C less than or equal to 8 percent at Screening visit

About this study

Official title: A Phase I Dose Escalation Open-Label Safety, Pharmacokinetic and Pharmacodynamic Study to Determine the Recommended Phase II Dose of GSK1120212 Dosed in Combination With GSK2141795

This study is a Phase 1 dose-escalation open-label study to determine the recommended Phase II dose (RP2D) and regimen for the combination of the orally administered MEK inhibitor GSK1120212 and the orally administered AKT kinase inhibitor GSK2141795. The study consists of two parts. Part 1A will identify the maximum tolerated dose (MTD) using a Zone-Based, modified 3 plus 3 dose escalation procedure. The starting dose (Zone 1, Cohort 1) will be 0.5mg GSK1120212 combined with 25mg GSK2141795. Dose escalation will continue based on predefined parameters until a MTD is established. The initial regimen for dose escalation in Part 1A will be continuous oral daily dosing. Once the continuous daily dosing MTD or RP2D has been established in Part 1A, Part 1B will explore alternate dosing schedule(s) in which the dosing schedule may be adjusted for either GSK1120212 or GSK2141795. Dose escalation will proceed using a 3 plus 3 dose escalation procedure until an MTD or RP2D of that alternate schedule is defined. Part 2 will explore further in specific tumor types the safety, tolerability, clinical activity, pharmacokinetic (PK) and pharmacodynamic (PD) properties of the combination of GSK1120212 and GSK2141795 at the recommended dose(s) and regimen(s) identified in Part 1.

Study groups in NCT01138085
Study groupRoleWhat they receive
Dose EscalationExperimentalDose escalation will proceed until unacceptable toxicity is observed. Dose escalation decisions will take into account all available data, including PK data and the safety profile of prior cohorts and will occur following review of these data by the investigator(s), GSK medical monitor, pharmacokineticist, and statistician.
Receives: Drug: GSK1120212; Drug: GSK2141795
Expansion CohortsExperimentalEnrollment into expansion cohort(s) in Part 2A may begin once a recommended dosing regimen(s) is identified in Part 1A utilizing a once daily continuous dosing schedule for both GSK1120212 and GSK2141795. Enrolment to cohorts utilizing this daily dosing schedule may proceed in parallel with enrolment in Part 1B. Expansion cohort(s) will preferentially enroll subjects with treatment-refractory, measurable and biopsiable triple negative breast cancer or BRAF- wild type melanoma. Subjects selected for enrollment into Part 2A or Part 2B will be tested for PTEN deficiency and must agree to provide paired tumor biopsies (at baseline and once while on- treatment). An additional tumor biopsy at the time of disease progression should also be collected if feasible. In Part 2A and Part 2B, up to 35 additional subjects per tumor type and schedule (i.e., a total of up to 70 subjects per schedule tested) may be enrolled in a two-stage design to better characterize safety, PK and PD.
Receives: Drug: GSK1120212; Drug: GSK2141795

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing GSK1120212 and GSK2141795 in people with Cancer, run by GlaxoSmithKline at 10 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 23 inclusion and 31 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 13 Nov 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 10 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Part 1A: To determine the safety, tolerability and recommended Phase II dose of GSK1120212 and GSK2141795 administered in combination orally, once daily continuously (time frame: Duration of study.). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01138085.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Nov 2017.
