Overview
Brief Summary
The purpose of this study is to determine the safety profile, the maximum tolerated dose (MTD) and the associated dose-limiting toxicities (DLTs) of S 81694 in combination with paclitaxel in metastatic breast cancer (mBC) patients, and to investigate the antitumour activity of the combination in metastatic triple negative breast cancer (mTNBC) patients.

Eligibility Criteria
Inclusion Criteria
- •For Phase I :
- •Histologically or cytologically confirmed metastatic breast cancer, refractory to any standard therapy or for which the standard therapy is considered unsuitable;
- •Patient must have at least one evaluable or measurable metastatic lesion (lesions as defined by revised Response Evaluation Criteria in Solid Tumors).
- •For Phase II :
- •Histologically or cytologically confirmed advanced inoperable triple negative breast cancer with no prior anticancer therapy regimen in metastatic setting;
- •Patient with a minimum washout period of 12 months following previous taxane based adjuvant therapy;
- •Patient must have at least one measurable metastatic lesion. Ascites, pleural effusion, and bone metastases are not considered measurable;
- •Acceptance of pre-treatment metastatic biopsies for all patients and on-treatment metastatic biopsies in selected centres.
- •For the whole study:
- •Male or female subjects aged ≥ 18 years old, or legal age of the majority in the country;
Exclusion Criteria
- •Other active malignancy within the last 3 years (except for basal cell carcinoma or a non-invasive/in situ cervical cancer or intra-mucosal gastro-intestinal cancers that were treated curatively);
- •Presence of grade ≥ 2 toxic effects (excluding alopecia) due to prior cancer therapy;
- •Known hypersensitivity to the IMP (S 81694 and paclitaxel) or their excipients;
- •Evidence of peripheral neuropathy of grade 2 or higher;
- •Participant previously received paclitaxel and discontinued due to toxicity related to paclitaxel;
- •Participant known as refractory to taxanes;
- •Any prior cancer therapy within 4 weeks or 5 half-life (whichever is the shorter) before the first IMP administration;
- •Participant with current, serious, uncontrolled infections;
- •Participant with brain metastasis or leptomeningeal metastasis (except patients with brain metastasis that have been stable post-radiation therapy and who are off steroids for \> 2 months);
- •History of cardiac disease;
Arms & Interventions
Combination therapy (S81694 + paclitaxel) phase I
Phase I: Single arm, non-randomized study in metastatic breast cancer patients. S81694 given intravenously every two weeks at different doses on D1 and D15 last for 28 days. The participants will also receive paclitaxel intravenously on D1, D8 and D15 last for 28 days.
Intervention: Combination therapy (S81694 + paclitaxel) phase I
paclitaxel phase II
Phase II: Randomised phase II part , two-arm, in untreated metastatic triple negative breast cancer patients. Paclitaxel given intravenously on D1, D8, and D15 at 80 mg/m² during a 28-day cycle.
Intervention: Paclitaxel
Combination therapy (S81694 + paclitaxel) phase II
Phase II: Randomised phase II part , two-arm, in untreated metastatic triple negative breast cancer patients. S 81694 given intravenously on D1 and D15 at recommended phase 2 dose (RP2D). Paclitaxel given intravenously on D1, D8, and D15 during a 28-day cycle.
Intervention: Combination therapy (S81694 + paclitaxel) phase II
