Phase 1b/2 Study of BKM120 Plus Trastuzumab in Patients With HER2-positive Breast Cancer

9 augusti 2016 uppdaterad av: Novartis Pharmaceuticals

A Phase Ib/II, Open Label, Multi-center Study Evaluating the Safety and Efficacy of BKM120 in Combination With Trastuzumab in Patients With Relapsing HER2 Overexpressing Breast Cancer Who Have Previously Failed Trastuzumab

This study will assess the safety and efficacy of BKM120 in combination with trastuzumab in patients with relapsing HER2 overexpressing breast cancer who have previously failed trastuzumab.

The study will further assess the safety and preliminary efficacy of BKM120 in combination with trastuzumab and capecitabine in patients with relapsing HER2 overexpressing breast cancer and brain metastases (BM) who have previously failed trastuzumab.

Intervention / Behandling
Experimentell: HER2+ metastatic breast cancer
Patients with HER2-overexpressing metastatic breast cancer, with or without PIK3 signaling pathway alteration, who have previously failed trastuzumab
Läkemedel: BKM120
Buparlisib (BKM120) is the investigational drug. Burparlisib was supplied as 10 mg and 50 mg hard gelatin capsules. Buparlisib was dosed on a flat scale of mg/day and not adjusted to body weight or body surface area. Buparlisib capsules were packaged in high density polyethylene bottles with a plastic child resistant closure.
Läkemedel: Trastuzumab
Trastuzumab was used in this study according to the local regulations in each participating country. A loading dose (4 mg/kg) of trastuzumab was administered (if required as assessed by the principal Investigator based on the timing of the last trastuzumab dose prior to enrollment) on Day -7 over 90 minutes, followed by weekly intravenous infusion of 2 mg/kg maintenance doses from Day 1 of Cycle 1 (over 30 minutes if the previous infusion was well tolerated).
Experimentell: HER2+ metastatic breast cancer with BM

Primära resultatmått

Resultatmått
Åtgärdsbeskrivning
Tidsram
Dose Limiting Toxicity (DLT) - Phase l Only
Tidsram: cycle 1 - 28 days
Determination of the maximum tolerated dose (MTD) in the dose escalation part of the study was based upon the estimation of the probability of DLT in Cycle 1 in patients of the dose-determining set.
cycle 1 - 28 days
Overall Response Rate (ORR) - Phase ll
Tidsram: 18 months

Objective response rate (ORR) was defined as the rate of patients with best overall response (BOR) equal to complete response (CR) or partial response (PR) according to RECIST 1.0 from the Investigators review.

Per Response Evaluation Criteria In Solid Tumors (RECIST) version 1.0 assessed of the disease status by imaging (i.e. CT/MRI): Complete Response (CR) = Disappearance of all tumor lesions; Partial Response (PR)= >=30% shrinkage of lesions; Overall Response (OR) = patients with CR and PR.

Åtgärdsbeskrivning
Tidsram
Disease Control Rate (DCR) Based on Investigator Assessment- Phase l & ll
Tidsram: 18 months

Disease control rate (DCR) = patients with complete response (CR), partial response (PR) or stable disease (SD) as per RECIST criteria.

Response Evaluation Criteria In Solid Tumors (RECIST) version 1.0 assessed the disease status by imaging (i.e. CT/MRI): CR = disappearance of all tumor lesions; PR = >=30% shrinkage of lesions; SD = Neither sufficient shrinkage to qualify for PR or CR nor an increase in lesions which would qualify for progressive disease (PD); PD = At least a 20% increase in the sum of the longest diameter of all measured target lesions, taking as reference the smallest sum of longest diameter of all target lesions recorded at or after baseline.
18 months
Clinical Benefit Rate (CBR) - Phase l & ll
Tidsram: 18 months

CBR = patients with CR, PR or SD ≥ 24 weeks according to RECIST by the investigator.

Response Evaluation Criteria In Solid Tumors (RECIST) version 1.0 assessed the disease status by imaging (i.e. CT/MRI): CR = Disappearance of all tumor lesions; PR= >=30% shrinkage of lesions; SD = Neither sufficient shrinkage to qualify for PR or CR nor an increase in lesions which would qualify for PD; PD = At least a 20% increase in the sum of the longest diameter of all measured target lesions, taking as reference the smallest sum of longest diameter of all target lesions recorded at or after baseline.
