pharmacogenomics ind exempt snp clinical study - crizotinib and single nucleotide polymorphisms

Conditions: Non-Small Cell Lung Cancer

Summary: explore the relationship between drug target alk gene single nucleotide polymorphisms and xalkori - crizotinib therapeutic-effects in patients with non-small cell lung cancer, based on oxford precisely sequencing drug targets' genes. explore the relationship between drug target cyp4503a gene single nucleotide polymorphisms and xalkori - crizotinib side-effects in patients with non-small cell lung cancer, based on oxford precisely sequencing drug targets' genes.

the usual approach group, after lung tissue biopsy, 300 double blind random group separated nsclc patients currently used the combined chemotherapy on xalkori - crizotinib capsule, film coated, it will try to look for the relationship between the crizotinib therapeutic efficacy and the alk snp genotyping, and the relationship between the crizotinib therapeutic safety and the cyp4503a snp genotyping, based on oxford precisely sequencing drug targets' genes. the study approach group, after lung tissue biopsy, 300 double blind random group separated nsclc patients currently used the combined chemotherapy on xalkori - crizotinib capsule, film coated, it will try to look for the relationship between the crizotinib therapeutic efficacy and the alk snp genotyping, and the relationship between the crizotinib therapeutic safety and the cyp4503a snp genotyping, based on oxford precisely sequencing drug targets' genes. 1. detect drug target whole gene precision sequence of everyone patient for all 600 recruited double blind nsclc patients. 2. mutually compare everyone patient drug target whole gene precision sequence for a total of 600 recruited double blind nsclc patients. 3. calculate drug target gene snps in all 600 recruited double blind nsclc patients. 4. correlate everyone patient drug target gene snp to everyone patient drug efficacy. 5. correlate everyone patient drug target gene snp to everyone patient drug safety. 6. mutually compare the usual approach group snps (300 double blind random group separated nsclc patients) with the study approach group snps (300 double blind random group separated nsclc patients). 7. confirm the relationship between drug target gene snps and drug efficacy. 8. confirm the relationship between drug target gene snps and drug safety.
