Brief Summary

This study of MK-8776 (SCH 900776) will evaluate its safety and tolerability when given as monotherapy or in combination with gemcitabine to participants with advanced solid tumors or lymphoma. Participants will be enrolled in cohorts that will receive sequentially higher doses of MK-8776 in combination with standard doses of gemcitabine The recommended combination doses for a Phase 2 trial (combination-RP2D) will be determined based on safety and biological activity. Up to 10 to 15 additional participants may be studied at the combination-RP2D.

Conditions

Hodgkin Disease; Lymphoma, Non-Hodgkin; Neoplasms

Outcome Measures

Primary Outcomes (3)

• Number of Participants Who Experienced a Dose-limiting Toxicity (DLT) During Cycle 0 and Cycle 1 Based on National Cancer Institute Common Terminology Criteria for Adverse Events Version 3.0 (CTCAE v 3.0)

  During Cycle 0, a DLT was defined as: CTCAE v 3.0 Grade 3 neutropenia or thrombocytopenia lasting ≥3 days; any CTCAE v 3.0 Grade 4 neutropenia or thrombocytopenia; neutropenic fever; any CTCAE v. 3.0 ≥ Grade 3 QT interval corrected by Fridericia (QTcF) prolongation of any duration; any other CTCAE v 3.0 Grade 3 or higher nonhematologic toxicity; or Grade 3 elevation of transaminases that resolved prior to administration of next dose(s) of study drug(s); delay in Cycle 1 Day 1 beyond 3 weeks due to continuing toxicity. During Cycle 1, a DLT was defined as: CTCAE v 3.0 Grade 4 neutropenia that persists for ≥7 days; neutropenic fever; CTCAE v 3.0 Grade 4 thrombocytopenia; CTCAE v 3.0 ≥ Grade 3 thrombocytopenia with bleeding; any CTCAE v 3.0 QTc ≥ Grade 3 QTcF prolongation of any duration; any other CTCAE v 3.0 Grade 3 or higher nonhematologic toxicity; or Grade 3 elevation of transaminases that resolved prior to administration of next dose(s) of study drug(s).

  Through Cycle 0 and Cycle 1 (Up to 42 days)

• Number of Participants Who Experienced an Adverse Event (AE)

  An AE was defined as any untoward medical occurrence in a participant administered study treatment which did not necessarily have to have a causal relationship with this treatment. An AE could have been any unfavorable and unintended sign (e.g. an abnormal laboratory finding), symptom, or disease temporally associated with the use of study treatment, whether or not considered related to study treatment. The number of participants who experienced an AE is presented.

  Up to approximately 72 weeks (Up to approximately 6 weeks after last dose of study treatment)

• Number of Participants Who Discontinued Study Treatment Due to an AE

  An AE was defined as any untoward medical occurrence in a participant administered study treatment which did not necessarily have to have a causal relationship with this treatment. An AE could have been any unfavorable and unintended sign (e.g. an abnormal laboratory finding), symptom, or disease temporally associated with the use of study treatment, whether or not considered related to study treatment. The number of participants who discontinued study treatment due to an AE is presented.

  Up to approximatey 66 weeks

Standard therapy is defined as therapy that is approved in a particular line of therapy or considered as standard of care based on published peer reviewed data in a specific line of therapy.
• Gemcitabine-naïve participants with tumors known to be responsive to gemcitabine or participants previously treated with gemcitabine who did not progress while on treatment or who are currently still responding to treatment should only be enrolled in cohorts for which gemcitabine doses are \>=1000 mg/m². Participants previously treated with gemcitabine, whose disease has progressed wile on treatment, can be enrolled to any part.
• Must be ambulatory with an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.
• Participants (and/or parent/guardian for participants who otherwise are unable to provide independent consent) must be willing to give written informed consent and able to adhere to dose and visit schedules.
• Female participants of childbearing potential must have a negative pregnancy test within 7 days of first dose of protocol therapy.
• Female participants of childbearing potential and male participants whose sexual partners are of childbearing potential must agree to abstain from sexual intercourse or to use an acceptable method of contraception during the study and for 90 days following the last dose of protocol therapy. Acceptable methods of contraception include condoms (male or female) with or without spermicidal agent, diaphragm or cervical cap with spermicide, medically prescribed intrauterine device (IUD), oral or injectable hormonal contraceptive, and surgical sterilization (eg, hysterectomy or tubal ligation).
• Must have adequate bone marrow reserve as evidenced by a white blood cell (WBC) count \>=3,000/ μL, absolute neutrophil count (ANC) \>=1,500/μL AND platelet count \>=100,000/μL.

• Participants, except those with known Gilbert's Syndrome, must have adequate hepatic function as evidenced by a serum bilirubin level \<=1.5 x the ULN AND serum levels of aspartate and alanine aminotransferase (AST/ALT) levels \<=3 x the ULN for the reference lab (participants with known hepatic metastases must have serum AST/ALT levels \<=5 x the ULN for the reference lab).
• Must be recovered from the effects of any prior surgery, radiotherapy or systemic antineoplastic therapy.

You may not qualify if:

• Has received radiation therapy within 3 weeks prior to first study drug administration after enrollment or radiation therapy to \>25% of bone marrow.
• Has received \>3 prior chemotherapy regimens (may have received prior gemcitabine). A participant may not have experienced any CTCAE v 3.0 \>Grade 1 myelotoxicity (neutropenia and/or thrombocytopenia) with any prior regimen, including gemcitabine. Participants with \>3 prior chemotherapy regimens, one or more of which were targeted, nonmyelosuppressive agents, may be considered on a case-by-case basis after discussion with the sponsor.
• Has undergone previous allogeneic or autologous stem cell transplant.
• Has had any of the following within 6 months prior to first study drug administration after enrollment: myocardial infarction, severe/unstable angina pectoris, coronary/peripheral artery bypass graft, symptomatic congestive heart failure, cerebrovascular accident or transient ischemic attack, or seizure disorder.
• Has a known bleeding diathesis, eg, hemophilia.
