Durvalumab and Tremelimumab for Pediatric Malignancies

Status: Active


The purpose of the study is to determine the recommended dose of durvalumab and tremelimumab (immunotherapy drugs) in pediatric patients with advanced solid and hematological cancers and expand in a second phase to test the efficacy of these drugs once this dose is determined.

Eligibility Criteria

Inclusion Criteria

  • Max Age =17 years
  • Solid Tumors (except primary central nervous system malignant tumors): Patients must have a histopathologic confirmation of malignancy. Patients must have progressed or are refractory to standard therapies, and for whom no standard of care treatments exist
  • Malignant neoplasms of hematopoietic and lymphoid tissue and myelodysplastic syndrome: pathologically confirmed relapsed or refractory advanced hematological malignancies including lymphoma and acute leukemia
  • Provision of diagnostic tumor sample mandated if available
  • Evaluable disease
  • No prior exposure to immune-mediated therapy
  • Adequate organ and marrow function
  • Life expectancy of at least 3 months

Exclusion Criteria

  • History of allogeneic organ transplantation (exceptions may be allowed for HL, NHL, ALL and AML, after discussion with Sponsor). History of autologous bone marrow transplant may be allowed (after discussion with Sponsor).
  • Active or prior documented autoimmune or inflammatory disorders (exceptions)
  • Uncontrolled intercurrent illness
  • History of primary immunodeficiency
  • Active infection including tuberculosis, hepatitis B, C or HIV
  • Any unresolved toxicity NCI CTCAE version 5.0 Grade ≥2 from previous anticancer therapy (exceptions)

Trial Objectives and Outline

This is a first time in pediatrics study primarily designed to evaluate the safety and tolerability of durvalumab and durvalumab in combination with tremelimumab at increasing doses in pediatric patients with advanced solid malignancies and hematological malignancies (including lymphomas) and for whom no standard of care treatments exist. Although treatment efficacy is not a primary objective of this study given its early phase nature, the patients screened for this study have no curative options and this study offers the potential of some benefit. The study will also characterize the PK of durvalumab and durvalumab in combination with tremelimumab in children and adolescents and explore potential biological activity and immunogenicity by assessing pharmacodynamics, anti drug antibody (ADA) levels, and anti-tumor activity. The results from this trial will form the basis for decisions for potential future pediatric studies.
