Brief Summary

This pilot study aims to evaluate the short-term and long-term safety, tolerability, and effectiveness of immunopheresis with the LW-02 column in removal of sTNFRs from plasma of patients with advanced, refractory NSCLC and to detect a potential disease control signal when employed in combination with low dose chemotherapy (ie, paclitaxel), immunotherapy (ie, atezolizumab) in patients who already failed first-line therapy, or as monotherapy in patients who already have failed second-line therapy.

Detailed Description

This is an open-label, Phase 2a pilot study of Immunicom's LW-02 column- combined with low-dose chemotherapy or immunotherapy in patients who have failed first-line treatment or employed as monotherapy in patients who have failed second-line therapy-to evaluate the short-term and long-term safety, tolerability and effectiveness of these approaches in removing sTNF-Rs and the potential for disease control in advanced, refractory NSCLC patients. Along with LW-02 column immunopheresis, patients enrolled in Arm 1 will receive combination immunotherapy with atezolizumab and patients enrolled in Arm 2 also will receive combination chemotherapy with paclitaxel. Patients in Arm 3 will be treated with LW-02 column immunopheresis alone as a third-line treatment regimen, assuming the first-line treatment included a platinum salt. Following study qualification, patients will be assigned to the appropriate treatment. All patients may receive up to 48 LW-02 column-based immunopheresis treatments over a 16-week (4-month) period with up to 3 treatments per week). Importantly, each LW-02 immunopheresis treatment should last up to 3 hours and process, approximately, 2 times the patient's plasma volume (2PV).

Each patient assigned to the treatment with LW-02 column-based immunopheresis will require central vascular access for the procedure. In general, a cuffed, tunneled dual-lumen catheter will be inserted into a central vein and remain in situ throughout the 16-week treatment phase (or longer if additional treatment is clinically indicated). The catheter will be used to connect the inlet and return lines of the apheresis system to the patient. Immunopheresis treatments will be performed using the LW-02 column used inline with a centrifugal apheresis system that allows for secondary plasma processing system (eg, the Terumo BCT Spectra Optia Apheresis System® or alternate apheresis system). Proper anticoagulation of the centrifugal apheresis device is generally provided by utilizing acid citrate dextrose formula A (ACD-A).

Patients will be followed and clinically evaluated for two-years posttreatment. In Year 1, patients will be clinically evaluated at 3, 6, 9, and 12 months from the end-of-treatment (EOT) visit. In Year 2 quarterly (every 3 months) telephone contacts will be made to determine overall survival.

Study Groups

LW-02 device immunopheresis combined with atezolizumab

LW-02 column immunopheresis treatments \~3x/week for 16 weeks plus atezolizumab 1200 milligrams (mg) q3w until disease progression or loss of clinical benefit, death, unacceptable toxicity, withdrawal of consent, or study termination by sponsor, whichever occurs first \[N=8\]

Group Type: EXPERIMENTAL

LW-02 device immunopheresis combined with atezolizumab

Intervention Type: DEVICE

The LW-02 device comprises an immunoadsorption affinity column, employing a proprietary human recombinant protein, single chain TNF-α ligand, covalently linked to a bead resin, that both enhances the capture efficiency of sTNF-Rs while avoiding complications from column leaching. Reduced sTNF-R plasma levels may lead to objective tumor responses. In combined treatment arm the immunopheresis procedure is combined with standard dose immunotherapy (atezolizumab) to potentially enhancing its cytotoxic effect.

LW-02 device immunopheresis combined with weekly paclitaxel

LW-02 column immunopheresis treatments \~3x/week for 16 weeks plus paclitaxel 80 mg/m2 /week × 6 followed by 2 weeks rest until disease progression, death, unacceptable toxicity, withdrawal of consent, or study termination by sponsor, whichever occurs first. \[N=8\]
