Phase 3 Trial of SRG-514 Administered Intraoperatively to Patients Undergoing Breast-Conserving Surgery

Official title

A Randomized, Phase 3 Trial of SRG-514 Administered Intraoperatively to the Site of Tumor Resection in Patients Undergoing Breast-Conserving Surgery for Triple Negative Breast Cancer

Overview

This is a Phase 3 trial to compare SRG-514 (active pharmaceutical ingredient \[API\]: ketorolac) administered intraoperatively to the tumor resection cavity with standard-of-care (SOC) versus SOC alone in participants with clinical stage II-III triple negative breast cancer (TNBC) undergoing breast-conserving surgery (BCS) who are neoadjuvant therapy naïve.

Detailed description

This is a Phase 3, multicenter, randomized, blinded trial to compare SRG-514 (active pharmaceutical ingredient \[API\]: ketorolac) administered intraoperatively to the tumor resection cavity with standard-of-care (SOC) versus SOC alone in participants with clinical stage II-III triple negative breast cancer (TNBC) undergoing breast-conserving surgery (BCS) who are neoadjuvant therapy naïve. Participants will be randomized 1:1 to receive SOC plus SRG-514 administered intraoperatively (treatment group) or SOC alone (control group). All participants will receive pre-operative and post-operative SOC.

Interventions

• Drug BCS + SRG-514
  BCS + SRG-514
• Procedure BCS
  BCS

Primary outcome measures

• EFS by BICR assessment [Time frame: EFS is defined as the time from randomization to the first occurrence of an event up to 5 years post BCS.]

Secondary outcome measures (1)

• Incidence and severity of TEAEs [Time frame: Events will be followed for up to 5 years post BCS.]

Eligibility criteria

Inclusion criteria

• Eligible participants will be adults (≥18 years old) who have a history of histologically confirmed diagnosis of TNBC (clinical stage II-III), except inflammatory breast cancer. Bilateral and/or multifocal primary tumors are allowed. For multifocal/multicentric disease, diagnosis needs to be confirmed for each focus. Participants have confirmed TNBC (as defined by the 8th edition of American Joint Committee on Cancer \[AJCC\] cancer staging manual and National Comprehensive Cancer Network \[NCCN\] guidelines), Eastern Cooperative Oncology Group (ECOG) Performance Status (PS) of ≤2, and plan to undergo breast-conserving surgical treatment of breast cancer with curative intent within 28 days of Screening.

Exclusion criteria

• Participants will not be eligible if they anticipate requiring the use of a drain after BCS, and/or have received neoadjuvant therapy, and/or are undergoing immediate reconstruction surgery with flaps involving transposition of a vascularized tissue flap from a remote donor site (oncoplastic closures are allowed), intraoperative radiation therapy (IORT) or brachytherapy requiring the placement of balloons or catheters during the lumpectomy procedure, and/or have a history of invasive malignancy (other than the disease under trial, ≤5 years prior to signing informed consent except for adequately treated basal cell or squamous cell skin cancer or in situ cervical cancer), and/or have stage IV disease.

Criteria are shown verbatim from the registry (in English). Final eligibility is always assessed by the study center.
