摘要
利妥昔单抗是一种单克隆抗体(mAb),是全球销量最大的10种药物之一,
预计2015年将超过70亿美元。 利妥昔单抗适用于治疗包括慢性
淋巴细胞性白血病(CLL)、B-B细胞非霍奇金淋巴瘤和各种自身免疫性疾病。
群体药代动力学研究显示,
利妥昔单抗在一个疗程后在血液中发现,这些水平与治疗相关,
成果。 在目前的给药方案下,相当一部分患者可能没有接受治疗。

英文摘要
Abstract
Rituximab is a monoclonal antibody (mAb) among the top 10 best-selling drugs, with global sales
estimated to exceed $7B in 2015. Rituximab is indicated to treat conditions including chronic
lymphocytic leukemia (CLL), B-cell non-Hodgkin's lymphoma, and various autoimmune disorders.
Population pharmacokinetic studies have revealed considerable differences in the final levels of
rituximab found in the blood after a course of therapy, and these levels correlate with therapeutic
outcomes. With current dosing regimens, a substantial fraction of the patients may not be receiving an
efficacious dose. During clinical development, laboratory-based tests are used to monitor rituximab
levels in patients, but these tests are not available to physicians after approval. Currently, there are no
point-of-care (POC) tests available to monitor the levels of rituximab in patients. The goal of this project
is to develop low cost POC devices that provide a quantitative measure of rituximab levels in blood.
These tests will help physicians personalize the dosing of patients and identify early rituximab treatment
failures resulting from low drug levels. Our core enabling technology platform is based on mimetope
peptides, termed VeritopesTM, that mimic the cognate ligand of a given mAb and specifically bind at the
antigen binding site. VeritopesTM are cheap, robust, and simple to integrate into lateral flow
immunoassay (LFA) that then enables inexpensive POC testing. In preliminary studies, we
demonstrated the feasibility of VeritopeTM-based LFA for the qualitative detection of rituximab,
trastuzumab, and bevacizumab levels in biologic fluids as well as the potential to develop quantitative
tests. In this Phase II project, we will complete the development of a CLIA-waivable rituximab monitoring
test that can be performed at the POC from a single drop of blood. We will integrate the LFA strips into
single-use, disposable digital LFA reader devices that can provide quantitative analysis of the test
strips. These devices will be validated in a clinical trial in partnership with UCSD Moores Cancer Center
using blood samples from patients treated with rituximab. The data generated during this Phase II study
will be incorporated in our technical data package to submit to FDA for clearance of our device, which
will be the first FDA cleared device for biologic drug monitoring at the POC.
This innovative product will fulfill of an unmet clinical need for a rapid, cost effective, and accurate dose
monitoring assay. Precision dosing through data-driven, personalized regimens will improve treatment
outcomes and maximize the efficient use of this and other monoclonal antibody therapeutics.
