Primary Purpose: Treatment
Official Title: A Phase 1, Open-Label, Multicenter, Dose Escalation And Expansion Study Of NKTR-214 In Subjects With Locally Advanced Or Metastatic Solid Tumor Malignancies

Further study details as provided by Nektar Therapeutics:

Primary Outcome Measures:
  • Safety of NKTR-214 as evaluated by incidence of drug-related adverse events (AEs), serious adverse events (SAEs), adverse events leading to discontinuation, deaths and clinical laboratory test abnormalities [ Time Frame: 30 days after last dose ]
  • Tolerability of NKTR-214 as evaluated by incidence of dose limiting toxicities (DLTs), drug-related adverse events (AEs), serious adverse events (SAEs), adverse events leading to discontinuation, deaths and clinical laboratory test abnormalities [ Time Frame: 30 days after last dose ]

Secondary Outcome Measures:
  • Objective response rate (ORR) of NKTR-214 based on investigator review of radiographic images [ Time Frame: Through study completion, an expected average of 1 year ]
  • Best overall response (BOR) in the population of interest [ Time Frame: Through study completion, an expected average of 1 year ]
  • Duration of Response (DOR) [ Time Frame: Through study completion, an expected average of 1 year ]
    It is defined as time between the date of first radiographic documented objective response and the date of the radiographic documented disease progression.

  • Progression-Free Survival (PFS) [ Time Frame: Through study completion, an expected average of 1 year ]
    PFS is defined as the time from date of enrollment to the date of the first objectively documented tumor progression or death due to any cause

  • Clinical benefit rate (CBR) [ Time Frame: Through study completion, an expected average of 1 year ]
    Clinical benefit rate will be assessed as the number of subjects with confirmed complete response (CR), partial response (PR), or stable disease (SD) (where the duration of SD should be ≥ 3 months) divided by the total number of subjects in the Response Evaluable Population

  • Median time to response (MTR) [ Time Frame: Through study completion, an expected average of 1 year ]
    The median time to response will be summarized descriptively for subjects who have a CR or PR.

  • Overall Survival (OS) [ Time Frame: Within 3 years from study start ]
    Overall survival is defined as the time from date of enrollment to the date of death.

  • Maximum observed plasma concentration (Cmax) of NKTR-214 [ Time Frame: Day 1 of Cycle 1 and 2: pre-dose and end of administration, 0.5 hr., 3 hr., 6 hr., Post dosing on Days 2, 3, 4, 5, 8, 11, and 15 for Cycle 1 and 2 ]
  • Time of maximum observed plasma concentration (Tmax) of NKTR-214 [ Time Frame: Day 1 of Cycle 1 and 2: pre-dose and end of administration, 0.5 hr., 3 hr., 6 hr., Post dosing on Days 2, 3, 4, 5, 8, 11, and 15 for Cycle 1 and 2 ]
  • Area under the plasma concentration time curve in the dosing interval AUC(TAU) of NKTR-214 [ Time Frame: Day 1 of Cycle 1 and 2: pre-dose and end of administration, 0.5 hr., 3 hr., 6 hr., Post dosing on Days 2, 3, 4, 5, 8, 11, and 15 for Cycle 1 and 2 ]
  • Half life (t½) of NKTR-214 [ Time Frame: Day 1 of Cycle 1 and 2: pre-dose and end of administration, 0.5 hr., 3 hr., 6 hr., Post dosing on Days 2, 3, 4, 5, 8, 11, and 15 for Cycle 1 and 2 ]
  • Functional and phenotypic characterization of peripheral immune cells by flow cytometry [ Time Frame: Day 1 and Day 8 of Cycle 1 and 2 ]
  • Changes in soluble cytokines and chemokines by multiplex immunoassay [ Time Frame: Day 1 and Day 8 of Cycle 1 and 2 ]
  • Functional and phenotypic characterization of tumor immune infiltrates (TIL) by flow cytometry. [ Time Frame: Pre-dose and week 3 after first dose ]
  • Functional and phenotypic characterization of tumor immune infiltrate (TIL) by next generation sequencing of T cell receptors [ Time Frame: Pre-dose and week 3 after first dose ]
  • Functional and phenotypic characterization of tumor immune infiltrate (TIL) by immunohistochemistry (IHC) [ Time Frame: Pre-dose and week 3 after first dose ]
  • Immunogenicity analysis to assess antibodies to NKTR-214 in human serum [ Time Frame: Screening and pre-dose of Day 1 of Cycle 2 and odd-numbered cycles there after (Cycle 3, 5, 7…) ]

Arms Assigned Interventions
Experimental: NKTR-214 Dose Escalation
This is a first in human, open-label, sequential dose escalation and expansion Phase 1 study of NKTR--214 in adult patients with locally advanced and metastatic solid tumors. The Phase 1 stage of the study is designed as an open-label dose escalation trial of NKTR--214 in participants with locally advanced or metastatic solid tumors. The goal of the dose escalation stage of the study is to find the recommended phase 2 dose, to evaluate the efficacy of NKTR--214 by assessing the objective response rate and to evaluate the safety of NKTR-214. Immunological biomarkers in plasma and tumor samples will also be measured.
Drug: NKTR-214
Participants in the dose escalation cohorts will be treated every 21 days (q21d) or every 14 days (q14d) until tumor progression.
