Spots Global Cancer Trial Database for A Study Comparing Immunopheresis® Alone or In Combination With Chemotherapy Versus Chemotherapy Alone in Treatment of Advanced Breast Cancer Patients

Study Description

Brief Summary: This is a multicenter, open-label, Phase 1/ 2 study to evaluate the short-term and longer-term safety, tolerability, and effectiveness of Immunopheresis® with the LW-02 column in removal of Soluble Tumor Necrosis Factor Receptors (sTNF-Rs) from plasma of patients with advanced, refractory Breast Cancer (BC) and for disease control when employed as monotherapy, or in combination with a low dose chemotherapy. A low dose chemotherapy will serve as control.

Detailed Description: This is a multicenter, open-label, Phase 1/ 2 study to evaluate the short-term and longer-term safety, tolerability, and effectiveness of Immunopheresis® with the LW-02 column in removal of sTNF-Rs from plasma of patients with advanced, refractory BC and for disease control when employed as monotherapy, or in combination with a low dose chemotherapy. A low dose chemotherapy will serve as control. Part A (n=10 evaluable patients): Overall safety, tolerability, and sTNF-R-removal effectiveness of LW-02 device-based immunopheresis monotherapy conducted 3 times per week for 4 weeks in patients with advanced TNBC. This part is already completed. Part B/Part B Extension (n = up to 30 evaluable patients): Overall safety, tolerability, and sTNF-Rs-removal effectiveness of LW-02 device-based Immunopheresis® 3 times per week for up to 16 weeks combined with low dose chemotherapy in patients with advanced refractory BC.. Part C (3 treatment arms; n=50 patients per treatment arm): Randomized comparison of overall safety, tolerability, and clinical efficacy effectiveness of (i) Immunopheresis® monotherapy with the LW-02 column 3 times per week for 16 weeks, (ii) or Immunopheresis® in combination with low dose chemotherapy, and (iii) plain low dose chemotherapy. Safety Endpoints 1. Safety and tolerability - incidence of Adverse Device Effects (ADEs), Serious Adverse Device Effects (SADEs) and Unanticipated Serious Adverse Device Effects (USADEs) related to immunopheresis procedure as well as Adverse Events (AE) and Serious Adverse Events (SAEs). 2. Safety endpoints of special interest - incidence of tumor lysis syndrome, and systemic inflammatory response syndrome. 3. Patient-Reported Outcomes to evaluate health status and Quality of Life (QoL) instruments for patients with BC: * Eastern Cooperative Oncology Group (ECOG) status * EQ-5D-5L index-based scale * EORTC: QLQ-BR23 (breast), and QLQ-C30 (general cancer questionnaire) * 6-minute walk test and BORG dyspnea, fatigue scale and hand grip test * Nutritional status will be assessed with PG-SGA scale and via laboratory assessments of changes in serum albumin and CRP Efficacy Endpoints 1. Column efficiency and effectiveness in removal of sTNF-Rs from patient plasma without clinically-meaningful leaching of capture ligand (SC-TNF-α) - change in sTNF-R and TNF-α plasma levels from initiation to the end of each Immunopheresis® procedure, including pre- and post-column measurements, between each treatment, and from baseline to end of a treatment cycle (4 weeks - Part A and B/B-extension, or 16 weeks - Part C). 2. Clinical endpoints - response in tumor burden - progression-free survival (PFS), disease control rate (DCR), objective response rate (ORR), clinical benefit rate (CBR), duration of response (DOR), duration of clinical benefit (DOCB), time-to-progression (TTP) and overall survival (OS). Serial evaluation of tumor burden/tumor growth is assessed according to Response Evaluation Criteria in Solid Tumors, Version 1.1 (RECIST v1.1).
