Definitions
- the host cell produces only two major antibody species, where each HC primarily pairs with its cognate LC, and most antibodies are those containing two heavy chains with the same amino acid sequence and two heavy chains with the same amino acid sequence. Tetramer of light chains (see PCT/US2017/030676).
- Partial response (PR) The sum of target lesion diameters is reduced by at least 30% from baseline.
- SAE Serious adverse events
- Blood routine no blood transfusion or correction with hematopoietic stimulating factor drugs within 14 days before obtaining the laboratory test: white blood cell count ⁇ 3.0 ⁇ 10 9 /L; absolute neutrophil count ⁇ 1.5 ⁇ 10 9 /L; platelets ⁇ 100 ⁇ 10 9 /L; hemoglobin ⁇ 90g/L;
- ZPML265 single agent combined with chemotherapy was used to treat 40 patients with extensive-stage small cell lung cancer.
- the efficacy analysis was based on 39 evaluable patients. As of January 16, 2023, the confirmed ORR was 89.7% (35/39) and 35 patients (92.1%).
- the best overall tumor assessment of the subjects was PR, 3 subjects (7.7%) subjects had the best overall tumor assessment of SD, 1 subject (2.6%) was PD, the overall DCR was 97.4% (38/39), 3 subjects
- the monthly PFS rate was 94.8%, and the median PFS was 5.7 months (95% confidence interval: 5.4-7.1 months).
Abstract
L'invention concerne une utilisation d'un agent de chimiothérapie combiné contenant un anticorps mixte anti-CTLA4 et anti-PD1, par exemple, carboplatine/cisplatine et étoposide, dans le traitement du cancer du poumon à petites cellules.
