Brief Summary

The purpose of this study was to investigate the efficacy and safety of pamiparib in patients with EGFR-TKIs-resistant NSCLC, using a single-center, dual-arm, open-label design.

Detailed Description

Lung cancer is the second most common cancer type worldwide and remains the leading cause of cancer death worldwide. Non-small cell lung cancer accounts for 80% of the total number of lung cancers, 15-55% of NSCLC have EGFR mutations, of which about 50% of Asians, targeted drugs - epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) ) showed good clinical benefit. However, patients with EGFR-mutant lung cancer experience disease progression within about a year of treatment with EGFR-TKIs, and acquired resistance develops and limits the long-term efficacy of these EGFR-TKIs. About 50% of EGFR-TKIs acquired resistance mutations by the mechanism of T790 mutation. Third-generation EGFR-TKIs can be used to overcome drug resistance against T790 mutation. Unfortunately, acquired resistance to third-generation EGFR-TKIs will eventually emerge, and when third-generation EGFR-TKIs acquire resistance, effective treatment options are still being explored. PARP (poly(ADP-ribose) polymerase) inhibitors represent a new class of anticancer therapy. They exploit synthetic lethality and induce cell death by exploiting defects in DNA repair, poly(ADP-ribose) polymerase-1 (PARP1) and poly(ADP-ribose) polymerase-2 (PARP2) are PARP enzymes Members of the family that play key roles in the DNA damage response (DDR) by acting as DNA damage sensors and signal transducers. PARP inhibitors can be used in combination with conventional NSCLC treatment regimens or as monotherapy. In clinical applications, PARP inhibitors have demonstrated sustained antitumor responses as single agents in BRCA1- or BRCA2-mutated patients. Studies have shown that the single-drug toxicity of PARP inhibitors is much lower than that of platinum drugs, and experimental results in NSCLC cell lines have shown that PARP inhibitors have single-drug activity in NSCLC. The characteristics of the domestic PARP inhibitor, Pamiparib, reflect its advantages over other PARP inhibitors: 1)low drug resistance, 2)high selectivity, 3)high capture of PARP-DNA complexes, 4)high membrane permeability, 5)Dual pathway metabolism, 6)Blood-brain barrier permeability. Multiple clinical data show that Pamiparib as a single agent has favorable safety and antitumor activity in advanced recurrent solid tumors.

Study Groups

Pamilarib in combination with Chemotherapy Drugs

The specific chemotherapy regimen was formulated by the investigator. The dosage of chemotherapy drugs is selected according to the drug use guidelines. Combination medication, the initial dose is 40mg each time (2 capsules), 2 times a day, the total daily dose is 80mg. Can be taken with a meal or on an empty stomach. If the patient misses a dose, no additional dose should be taken, and the next prescribed dose should be taken normally at the planned time. Continue the treatment until the disease progresses or unacceptable adverse reactions occur, and the dose is adjusted.
