CAR T 细胞长期暴露于肿瘤抗原可导致 CAR T 细胞耗竭和肿瘤扩张。为了扭转这种疲惫,我们开发了两种正交策略,专门针对用尽的 CAR T 细胞靶向有效的 TLR7 激动剂。我们在此证明,这两种策略都能使衰竭的 CAR T 细胞恢复活力,从而导致 T 细胞衰竭标志物 (PD-1 + Tim-3 + ) 的显着减少和 CAR T 细胞抗性肿瘤的缩小。
The present invention relates to immune response modifiers of formula (I), which act selectively through agonism, of Toll-Like Receptors (TLRs), uses thereof, processes for the preparation thereof, intermediates used in the preparation thereof and compositions containing said inhibitors. These inhibitors have utility in a variety of therapeutic areas including the treatment of infectious disease such as Hepatitis (e.g. HCV, HBV), genetically related viral infection and cancer.
Pharmaceutical compositions comprising a poorly water soluble ionizable drug, a cationic species and a dispersion polymer are disclosed, together with a process for forming the compositions. The neutral form of the drug has (i) a solubility of less than 1 mg/ml, in aqueous solution at a pH between 6 and 7, (ii) a solubility of less than 20 mg/mL in a volatile organic solvent, and (iii) an acidic pKa value of greater than 5. At least 90 wt % of the drug in the solid dispersion being in a non-crystalline form. The drug, the cationic species, and the dispersion polymer constitute at least 80 wt % of the solid dispersion.
