Brief Summary:
A two part, Phase 1b/2 study to define a recommended Phase 2 dose of VRx-3996 in combination with valganciclovir (Phase 1b) designed to evaluate the efficacy of this combination in relapsed/refractory EBV+ lymphomas.

Condition or disease Intervention/treatment Phase
Epstein-Barr Virus Associated Lymphoma Lymphoproliferative Disorders Drug: VRx-3996 Drug: Valganciclovir Phase 1 Phase 2

Detailed Description:
The purpose of this study is to determine whether VRx-3996 in combination with valganciclovir is safe, determine the side effect profile, and to determine whether this therapy may help patients with EBV-related lymphomas. The study has two phases. Goals of the first phase include determining a safe and tolerable dose that can be administered in phase 2. Goals of the second phase include further evaluating the safety and tolerability of VRx-3996 in combination with valganciclovir, evaluating how the drugs are metabolized in the body, evaluating response rates and other exploratory objectives that will help the researchers evaluate how these drugs work in the body. Participants will receive daily oral doses of the two study drugs and will have multiple study visits where they will have blood collected, physical examinations, and other medical monitoring.

Primary Outcome Measures :
  1. Incidence of Adverse Events and changes in clinical safety laboratory values in Dose Escalation and Cohort Expansion [ Time Frame: Approximately 2 years ]
    Determination of a safe and tolerable Recommended Phase 2 Dose (RP2D)

  2. Incidence of Dose Limiting Toxicities in in Dose Escalation and Cohort Expansion [ Time Frame: Approximately 2 years ]
    Determine safety and tolerability

  3. ORR as measured by stable disease (SD), partial response (PR), and complete response (CR) by radiographic assessment [ Time Frame: Approximately 2 years ]
    Disease response will be assessed using a combination of physical exam and imaging


Secondary Outcome Measures :
  1. Single-dose and steady-state Cmax of VRx-3996 and valganciclovir [ Time Frame: Through study completion, an average of 6 months ]
    PK assessment of both VRx-3996 and valganciclovir at 0, 1, 1.5, 2, 3, 5 and 7 hours post-dose on C1D1 and pre-dose on Day 1 of all following cycles

  2. Single-dose and steady-state AUC of VRx-3996 and valganciclovir [ Time Frame: Through study completion, an average of 6 months ]
    PK assessment of both VRx-3996 and valganciclovir at 0, 1, 1.5, 2, 3, 5 and 7 hours post-dose on C1D1 and pre-dose on Day 1 of all following cycles

  3. Steady-state Elimination half-life of VRx-3996 and valganciclovir [ Time Frame: Through study completion, an average of 6 months ]
    PK assessment of both VRx-3996 and valganciclovir at 0, 1, 1.5, 2, 3, 5 and 7 hours post-dose on C1D1 and pre-dose on Day 1 of all following cycles

  4. Time to response [ Time Frame: Approximately 6 months ]
    The time from the start of first study drug administration to the first overall tumor response observed for subjects who achieved a CR or PR

  5. Duration of response [ Time Frame: Up to approximately 2 years ]
    The time interval (days) from date of the first overall response (CR or PR; achieved after the study drug administration) to the date of disease progression

  6. Progression-free survival [ Time Frame: Up to approximately 2 years ]
    The interval between the date of first study drug administration and the date of PD or death, whichever is first reported
