Abstract 1359


While doxorubicin has been the mainstay of treatment for decades, in more recent years gemcitabine plus docetaxel has emerged as an effective treatment in metastatic STS. The platelet-derived growth factor receptor alpha (PDGFR α) antibody olaratumab in combination with doxorubicin demonstrated a significant improvement of overall survival over doxorubicin alone in patients with advanced STS in a randomized phase 2 study (NCT01185964). Since some patients may not be appropriate candidates for doxorubicin-based chemotherapy, or have received prior anthracycline treatment, exploring the efficacy and safety of olaratumab with gemcitabine plus docetaxel is of considerable interest.

Trial design

ANNOUNCE 2 (NCT02659020) is a multicentre Phase 1b/2 study of olaratumab in combination with gemcitabine and docetaxel in patients with advanced or metastatic STS (≥16 years; ECOG performance status ≤1; naïve to therapy with study drugs; not amenable to curative treatment with surgery or radiotherapy; ≤2 prior lines of systemic therapy for advanced or metastatic disease). The Phase 1b part of the study consists of an open-label, single-arm, dose-escalation assessment of the safety and tolerability of olaratumab administered at 15 mg/kg (Days 1 and 8) or 20 mg/kg (Days 1 and 8) with gemcitabine (900 mg/m2 [fixed dose rate: 10 mg/m2/minute] Days 1 and 8) and docetaxel (75 mg/m2 Day 8) in a 21-day cycle. The primary objective is to determine a dose of olaratumab that may be safely administered in combination with gemcitabine and docetaxel in patients with advanced or metastatic STS. Secondary objectives are to evaluate the safety and toxicity profile, pharmacokinetics, and immunogenicity of olaratumab in combination with gemcitabine and docetaxel; and to document any antitumor activity. After the optimal dose of olaratumab in combination with gemcitabine and docetaxel has been determined, the Phase 2, randomized, double-blind, placebo-controlled part of the study will open to enrolment (in approximately December 2016). The study began in March 2016; planned enrollment for the 1b phase is approximately 30 patients.
