Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase 2a Open-Label Multi-Center Study Evaluating HQK-1004 Administered With Valganciclovir in Patients With Relapsed or Refractory Epstein-Barr Virus-Positive Lymphoid Malignancies or Lymphoproliferative Disorders

Primary Outcome Measures:
  • Overall response rate [ Time Frame: Days 21, 42, 84 and 126 ]

Secondary Outcome Measures:
  • Safety and tolerability as measured by adverse events, physical exams, ECG, and laboratory evaluations [ Time Frame: through end of treatment (up to Day 126) and 30 days post last dose ]
  • Overall and progression-free survival [ Time Frame: through end of treatment (up to Day 126), then every 8 weeks for 1 year post last dose ]

Enrollment: 1
Study Start Date: May 2010
Primary Completion Date: November 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: HQK-1004 + Valganciclovir Drug: HQK-1004
1,000 mg/kg/day administered IV 24 hours/day for 5 days (Days 1-5 of each 21 day cycle)
Other Name: arginine butyrate
Drug: Valganciclovir (may substitute with ganciclovir)
900 mg BID oral for 21 days (Days 1-21 of each 21 day cycle). If the subject cannot tolerate or absorb valganciclovir, ganciclovir my be administered instead at 5 mg/kg intravenously BID until the subject can tolerate and absorb valganciclovir.


Ages Eligible for Study:   3 Years and older   (Child, Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Histologically confirmed lymphoid malignancy or lymphoproliferative disorder with EBV detected by either immunohistochemistry or in situ hybridization. Pathology can be assessed on either a current or previous biopsy. All disease stages are eligible
  • Disease that is refractory or relapsed after at least one prior standard therapeutic regimen, which includes biologic agents (e.g., monoclonal antibodies), chemotherapy or chemoradiotherapy regimens. Prior therapy may include high dose chemotherapy and stem cell rescue or bone marrow transplantation
  • Bidimensionally measurable disease by computerized tomography (CT) or magnetic resonance imaging (MRI; patients with sensitivity to contrast or for tumor types that are less accurately measured by CT) scan or physical measurement (cutaneous lesions only) with at least 1 lesion ≥ 10 mm in the greatest diameter. PET-CT should be used at baseline for patients with Hodgkin's Disease (HD) or diffuse large B-cell lymphoma (DLBCL).
  • Absolute neutrophil count ≥ 500/mm3 and platelet count ≥ 50,000/mm3
  • Bilirubin ≤ 2.0 times upper limit of normal (ULN) with the exception of patients with Gilbert's syndrome (bilirubin ≤ 3.5 times ULN allowed), and both AST and ALT ≤ 3 times ULN
  • Serum creatinine ≤ 2.0 mg/dL

Exclusion Criteria:

  • Patients who have not recovered from previous treatment with chemotherapy
  • Patients who have been treated with biologic agents within two weeks prior to first dose of HQK-1004
  • Uncontrolled ischemic heart disease or uncontrolled congestive heart failure, or myocardial infarction within the past 3 months
