NCT02901483

Brief Summary

It's a prospective, open-label, single arm, nonrandomized study of PEP503 in head and neck squamous cell carcinoma (HNSCC) patients.

  • Escalation portion (Phase 1b):A 3 + 3 dose escalation study design will be adopted in this phase to identify the recommended intratumor injection volumes of PEP503.
  • Expansion portion (Phase 2): Following confirmation of the recommended volumes, 18 additional patients will be enrolled at the recommended volume level to evaluate for safety and efficacy.

Outcome Measures

Primary Outcomes (3)

  • Phase 1: Determination of the Recommended doses and the Dose Limiting Toxicities (DLT)

    To determine the Recommended volumes and the Dose Limiting Toxicities (DLT) of PEP503 administered as intratumor injection, activated by CCRT

    24 months

  • Phase 2: The rate of locoregional control at one year

    To evaluate the rate of locoregional control at one year after PEP503 intratumor injection

    24 months

  • Phase1 and 2: Evaluation of Safety profile of PEP503

    Safety of PEP503, as intratumor injection schedule, activated by CCRT will be assessed in terms of incidence and severity of clinical and laboratory Adverse Events by NCI-CTCAE version 4.0

    24 months

Secondary Outcomes (4)

  • Phase 1: The body kinetic profile of PEP503

    24 months

  • Phase 2: Evaluation of objective tumor response as per Response Evaluation Criteria in Solid Tumors (RECIST)

    24 months

  • Phase 2: Pathological response (pR)

    24 months

  • Phase 2: Evalution of progression free survival rate at 1 year

    24 months

Study Arms (1)

PEP503+Cisplatin+Radiotheraphy

EXPERIMENTAL

Phase 1b: There are 6 levels (L1- 5% + 40mg/m2 weekly cisplatin, L2- 10% + 40mg/m2 weekly cisplatin, L3- 15% + 40mg/m2 weekly cisplatin, L4-22% + 100mg/m2 tri-weekly cisplatin, L3a- 15% + 100mg/m2 tri-weekly cisplatin, and L5- 33% + 100mg/m2 tri-weekly cisplatin) in this phase 1b study. Only primary tumor will receive PEP503 implementation via intratumor injection. A 3 + 3 dose escalation study design will be adopted in this phase to identify the recommended intratumor injection volumes of PEP503. Phase 2: The recommended volume identified from phase 1b will be applied in phase 2 for both primary tumor and ≥ 3 cm lymph node lesions.

Drug: PEP503Drug: CisplatinRadiation: Radiotherapy

Interventions

PEP503DRUG

PEP503 will be administered by intratumoral route as slow injection

Also known as: NBTXR3
PEP503+Cisplatin+Radiotheraphy

The concurrent chemoradiotherapy. Weekly cisplatin 40 mg/m2 or tri-weekly 100 mg/m2, depending on which dose level patients are in, with a minimum of accumulated 200 mg/m2 during the 7\~8 weeks' radiation period.
