suzhou, march 11, 2021 - alphamab oncology (stock code: 9966.hk) announced that data from phase ib/ii clinical study (clinical trial no.: kn046-203) of pd-l1/ctla-4 bispecific antibody kn046 in combination with nab-paclitaxel for the treatment of patients with metastatic triple-negative breast cancer (mtnbc) will be presented in a poster at the 112th american association for cancer research (aacr 2021 virtual meeting) in april 2021.


founded in 1907, the american association for cancer research (aacr) is one of the largest cancer meetings in the world and widely considered by the global cancer community to be the touchstone event that sets the cancer research agenda. it attracts nearly 20,000 professionals from all over the world each year with its spectrum of cancer science and excellent reputation, accelerates the dissemination of new research findings among scientists and others dedicated to the conquest of cancer; promotes science education and training; and advances the public understanding of cancer. due to the pandemic, the 2021 aacr will be held virtually from april 10-15 and may 17-21, local time (eastern time).


the abstract of the research:

title:

preliminary safety, tolerability and efficacy results of kn046 (anti-pd-l1/ctla-4 bispecific antibody) in combination with nab-paclitaxel in metastatic triple-negative breast cancer (mtnbc)

presentation format: poster

poster launch time: april 10, 2021, 8:30 a.m.et, u.s. time


kn046-203 is a phase ib/ii, open label, multi-center clinical study, evaluating the efficacy, safety, and tolerability of kn046 combined with nab-paclitaxel in patients with metastatic tnbc. a total of 27 patients with treatment-naïve locally advanced inoperable or metastatic tnbc were enrolled in the study. the results show that kn046 is well tolerated and effective as a treatment for advanced triple-negative breast cancer, especially in pd-l1-positive tnbc patients, showing a progression-free survival (pfs) benefit.


breast cancer is the most common malignant tumor among women in the world, and its morbidity and mortality are increasing year by year. among them, triple-negative breast cancer lacks the expression of estrogen receptor (er), progesterone receptor (pr) and human epidermal growth factor receptor 2 (her2). tnbc is highly invasive, has a high recurrence rate, and a poor prognosis. endocrine therapy and her-2 targeted therapy are not effective for tnbc. chemotherapy is currently a common choice for systemic treatment of tnbc, but its side effects are obvious, and once a patient develops resistance to chemotherapy drugs, the tumor may quickly recur and metastasize.
