Study Details

Study Description

Brief Summary

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

Condition or DiseaseIntervention/TreatmentPhase
  • Drug: Durvalumab / Tremelimumab Combination Therapy
Phase 1/Phase 2

Detailed Description

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

Arms and Interventions

Experimental: Durvalumab / Tremelimumab Combination Therapy

Part 1 (dose finding) Durvalumab + tremelimumab Combination Treatment. Durvalumab and tremelimumab are initially administered at dose level 1 and dose escalated based on results from PK modeling and tolerance to determine the RP2D. Both drugs are administered every 4 weeks as intravenous infusions. Tremelimumab is only administered with durvavalumab for 4 doses, from cycles 2-5. (sarcoma, NB and NHL) Part 2 (dose expansion phase) Durvalumab + tremelimumab Combination Treatment. Durvalumab and tremelimumab are administered at the RP2D, every 4 weeks as intravenous infusions. Tremelimumab is only administered with durvalumab for 4 doses, from cycles 1-4. Tremelimumab may be added for 4 doses at time of progressive disease. Cohorts: solid tumors, sarcomas, NHL restricted to PMBCL and ALCL subtypes)

Drug: Durvalumab / Tremelimumab Combination Therapy
Starting dose: durvalumab: 20mg/kg tremelimumab: 1mg/kg at cycles 2 to 5 only co-administered with durvalumab. The Recommended Phase 2 dose will be used for the dose expansion phase.
Other Names:
  • durvalumab: Imfinzi, MEDI4736
  • tremelimumab: CP-675,206
  • Outcome Measures

    Primary Outcome Measures

    1. Dose Finding phase: Recommended Phase 2 Dose [15 months]

      Endpoints include adult equivalent dose for both durvalumab (administered as monotherapy and in combination) and for tremelimumab, to reflect the RP2D regimen dose for durvalumab monotherapy and for the combination treatment

    2. Safety and Tolerability [Up to 4 years.]

      Evaluated based on adverse events occurring throughout the study

    3. Objective Response Rate (dose expansion phase only) [up to 4 years.]

      Number (%) of patients achieving complete or partial response according to RECIST 1.1. (solid tumors) and disease-specific response criteria.

    Secondary Outcome Measures

    1. Pharmacokinetics (PK) of Durvalumab and Tremelimumab [15 months.]

      Serum concentrations of Durvalumab and Tremelimumab
