A Study of Novel Anti-cancer Agents in Patients With Metastatic Triple Negative Breast Cancer

Phase 1
Active, not recruiting
Conditions
Triple Negative Breast Neoplasms
Interventions
Registration Number
NCT03742102
Lead Sponsor
AstraZeneca
Brief Summary

This study is designed to determine the efficacy and safety of durvalumab in combination with novel oncology therapies with or without paclitaxel and durvalumab + paclitaxel for first-line metastatic triple negative breast cancer

Detailed Description

This is a Phase IB/II, 2-stage, open-label, multicenter study to determine the efficacy and safety of durvalumab in combination with novel oncology therapies (i.e. therapies designed for immune modulation) with or without paclitaxel and durvalumab + paclitaxel as first-line treatment in patients with metastatic triple negative breast cancer (TNBC). The study is designed to concurrently evaluate potential novel treatment combinations with clinical promise using a 2-stage approach. The study will use a Simon 2-Stage design to evaluate which cohorts may proceed to expansion.

Part 1 is a Phase IB study of safety and initial efficacy, and Part 2 may expand patient enrollment if adequate efficacy signal is observed in Part 1. The treatment regimens evaluated in Part 2 will depend on the evaluation of safety and efficacy outcomes in Part 1.

Primary Outcome Measures
NameTimeMethod
Incidence of adverse eventsPart1: From informed consent until the safety follow-up visit 3 months after the last dose of study drug. Part 2: From informed consent until the safety follow-up visit 3 months after the last dose of study drug.

Part 1: Assessment of safety and tolerability of each treatment arm

Part 2:

Endpoints based on Investigator assessment according to RECIST 1.1: ORR (objective response rate): The percentage of evaluable patients with a confirmed Investigator-assessed visit response of CR (complete response) or PR (partial response).

Laboratory findingsPart 1: From informed consent until the safety follow-up visit 3 months after the last dose of study drug. Part 2:From informed consent until the safety follow-up visit 3 months after the last dose of study drug.

Assessment of safety and tolerability of each treatment arm

Secondary Outcome Measures
NameTimeMethod
Presence of anti-drug antibodies (ADAs) for durvalumab and applicable novel oncology therapiesFrom cycle 1 day 1 until cycle 7 day 1 (Arms 1-5), from cycle 1 day 1 until cycle 8 day 1 (Arms 6-8) (each cycle is 28 days) and every 12 weeks thereafter until study completion approx. 30 months

Investigation of the immunogenicity of durvalumab and novel oncology therapies in all applicable treatment arms Applicable for Part 1 (Arms 1-8) and for Part 2 (Arm 7)

Progression-free survival (PFS 6)On-study tumor assessments occur every 8 weeks until week 48 (Arms 1-5), every 6 weeks until week 48 (Arms 6-8) and then every 12 weeks thereafter until radiological progression, death, withdrawal of consent or study completion up to approx. 30 months

PFS at 6 months following date of first dose Applicable for Part 2

Serum concentration of durvalumab and serum or plasma concentration of novel oncology therapiesFrom cycle 1 day 1 until cycle 7 day 1 (Arms 1-5), from cycle 1 day 1 until cycle 8 day 1 (Arms 6-8) (each cycle is 28 days) and every 12 weeks thereafter until study completion approx. 30 months

Assessment of pharmacokinetics (PK) Applicable for Part 1 (Arms 1-8) and for Part 2 (Arm 7)

Objective response rate (ORR)Approx. 30 months

Assessment of the efficacy of each treatment arm according to RECIST 1.1. ORR: The percentage of evaluable patients with a confirmed Investigator-assessed response of CR (complete response) or PR (partial response) Applicable for Part 1 and Part 2.

Duration of response (DoR)On-study tumor assessments occur every 8 weeks (Arms 1-5), every 6 weeks (Arms 6-8) until week 48 and then every 12 weeks thereafter until radiological progression, death, withdrawal of consent or study completion up to approx. 30 months

Assessment of the efficacy of each treatment arm according to RECIST 1.1. DoR: Time from date of first detection of objective response (which is subsequently confirmed) until the date of objective radiological disease progression Applicable for Part 1 and Part 2

Progression-free survival (PFS).On-study tumor assessments occur every 8 weeks (Arms 1-5),every 6 weeks (Arms 6-8) until week 48 and then every 12 weeks thereafter until radiological progression, death, withdrawal of consent or study completion up to approx. 30 months

Assessment of the efficacy of each treatment arm according to RECIST 1.1. PFS: Time from date of first dose until the date of objective radiological disease progression or death (by any cause in the absence of progression)

Applicable for Part 1 and Part 2

Overall survival (OS)Approx. 30 months

OS: Time from date of first dose until the date of death by any cause

Applicable for Part 1 and Part 2
