Clinical Trial Summary

Progression of DLBCL is the major obstacle for the success of chimeric antigen receptor-T cell (CAR-T) with approximately 60% of the patients relapsing in the first year, and 40% within 3 months, after infusion. While patient with DLBCL in Partial Response/Complete Response at lymphodepletion have a 1-year Progression Free Survival (PFS) of 60-80%, those with Stable Disease/Progressive Disease at time of lymphodepletion have a dismal PFS of 20-30%.

Trials showed that better expansion of CAR-T cells, even in patients with a progressive disease, may overcome this grave prognosis and may result in better PFS

Description:

Factors that may introduce resistance to CAR-T. in addition to the bulk of disease, include also expression of check point molecules that eventually interfere with the CAR-T action. The investigator, have recently shown (EBMT 2022, # LWP-03) a real-life data, that day +7 CAR-T concentration in patients with stable or progressive disease (SD/PD) at lymphodepletion segregates patients to those with high CAR-T blood concentrations that achieve a high CR/PR rate after CAR-T infusion ,those with 20-100 CAR-T cells/microL that achieve a lower CR/PR rate after CAR-T infusion, and those with <20 cells/microL that achieve the lowest CR/PR rate after infusion. Thus, the extent of CAR-T cell expansion on day 7 after treatment is a prognostic marker predicting response to treatment in this patient group. Considering all these - patients with SD/PD at time of lymphodepletion, and specifically those with lower CAR-T blood concentrations on day +7 are at a very high risk for early disease progression after CAR-T infusion and, as such, there is an urgent unmet medical need to improve their outcomes.

Addition of anti PD-1 to patients with low expansion of CAR-T cells may overcome the inhibitory effect of PD-1 expression and may result in a better function of the CAR-T and eventually tumor suppression.

Nivolumab is a human monoclonal antibody targeting (programmed death-1 ) PD-1, a negative regulatory molecule expressed by activated T and B lymphocytes. Anti PD-1 treatment has been administered as a single dose or repeated administration in different time points during CAR-T cell therapy. These studies showed that this treatment is safe, well tolerated and does not result in increased CAR-T associated toxicities, mainly cytokine release syndrome(CRS) and immune effector cell associated neurotoxicity(ICANS). The optimal time window to administer these agents for achieving safety and efficacy is not determined.
