Phase 1
Completed
Conditions
Advanced Solid Tumors
Interventions
Biological: MEDI1873
Registration Number
NCT02583165
Lead Sponsor
MedImmune LLC
Brief Summary

To evaluate the safety and tolerability of MEDI1873 in adult subjects with selected advanced solid tumors.

Detailed Description

This is a first-time-in-human, Phase 1, multicenter, open-label, single-arm dose-escalation study of MEDI1873 to evaluate the safety, tolerability, pharmacokinetics, immunogenicity, pharmacodynamics and anti-tumor activity in adult subjects with advanced solid tumor malignancies

Inclusion Criteria
  • All subjects must consent to provide archived tumor specimen
  • Subjects must have histologically or cytologically confirmed advanced solid tumor for recurrent or metastatic disease.
  • At the time of Day 1 of the study, subjects with central nervous system (CNS) metastases must have been treated and must be asymptomatic
  • Willingness to provide pretreatment and on-treatment biopsies.
  • Adequate organ function
  • Females of childbearing potential and nonsterilized males who are sexually active must use effective methods of contraception
Exclusion Criteria
  • Known allergic reaction to any component of MEDI1873
  • Concurrent enrollment in another clinical study, unless it is an observational clinical study or the follow-up period of an interventional study
  • Receipt of any anticancer therapy within 4 weeks prior to the first dose of MEDI1873; in the case of mAbs, 6 weeks prior to the first dose of MEDI1873
  • Any concurrent chemotherapy, immunotherapy, biologic, or hormonal therapy for cancer treatment.
  • Receipt of live, attenuated vaccine within 28 days prior to the first dose of investigational product
  • Unresolved toxicities from prior anticancer therapy
  • Any condition that, in the opinion of the investigator or sponsor, would interfere with evaluation of the investigational product.

Primary Outcome Measures
NameTimeMethod
Number and percentage of subjects with adverse events (AEs), serious adverse events (SAEs), and dose-limiting toxicities (DLTs)From time of informed consent through 12 months after last dose of MEDI1873

The maximum tolerated dose (MTD)/highest protocol-defined dose level in the absence of establishing an MTD will be determined by the number of participants experiencing DLTs. The safety profile will be assessed through number of participants experiencing AEs, SAEs, DLTs, abnormal laboratory parameters, vital signs and electrocardiogram (ECG) results.

Secondary Outcome Measures
NameTimeMethod
Overall survival (OS)Estimated to be from time of informed consent up to 4.5 years

Overall survival will be determined as the time from the start of treatment with MEDI1873 until death due to any cause.

Number of subjects who develop detectable anti-drug antibodies (ADAs)From first dose of MEDI1873 through to 12 months after last dose of MEDI1873

The immunogenicity of MEDI1873 will be assessed by summarizing the number of subjects who develop detectable anti-drug antibodies (ADAs)

Objective response rate (ORR)Estimated to be from time of informed consent up to 4.5 years

The ORR is defined as the proportion of subjects with confirmed CR or confirmed PR, based on RECIST Version 1.1

Terminal half-life of MEDI1873From first dose of MEDI1873 through to 30 days after last dose of MEDI1873

The endpoint for assessment of PK of MEDI1873 include serum concentrations of MEDI1873 at different timepoints after MEDI1873 administration

Maximum observed concentration (Cmax) of MEDI1873From first dose of MEDI1873 through to 30 days after last dose of MEDI1873

The endpoint for assessment of PK of MEDI1873 include serum concentrations of MEDI1873 at different timepoints after MEDI1873 administration

Disease control rate (DCR)Estimated to be from time of informed consent up to 4.5 years

The DCR is defined as the proportion of subjects with CR, PR, or SD (subjects achieving SD will be included in the DCR if they maintain SD for ≥8 weeks) based on RECIST Version 1.1

Duration of response (DoR)Estimated to be from time of informed consent up to 4.5 years

Duration of response will be defined as the duration from the first documentation of objective response to the first documented disease progression or death due to any cause, whichever occurs first.

PD biomarkers including changes from baseline levels in various lymphocyte populationsFrom time of informed consent through to disease progression, assessed up to 4.5 years

PD biomarkers including changes from baseline levels in various lymphocyte populations

Area under the curve (AUC) of MEDI1873From first dose of MEDI1873 through to 30 days after last dose of MEDI1873

The endpoint for assessment of PK of MEDI1873 include serum concentrations of MEDI1873 at different timepoints after MEDI1873 administration

Progression-free survival (PFS)Estimated to be from time of informed consent up to 4.5 years

Progression-free survival will be measured from the start of treatment with MEDI1873 until the first documentation of disease progression or death due to any cause, whichever occurs first.

Percentage of subjects who develop detectable anti-drug antibodies (ADAs)From first dose of MEDI1873 through to 12 months after last dose of MEDI1873

The immunogenicity of MEDI1873 will be assessed by summarizing the percentage of subjects who develop detectable anti-drug antibodies (ADAs)

Clearance (CL) of MEDI1873From first dose of MEDI1873 through to 30 days after last dose of MEDI1873

The endpoint for assessment of PK of MEDI1873 include serum concentrations of MEDI1873 at different timepoints after MEDI1873 administration
