Antitumor activity of a novel HER3-targeting antibody-drug-conjugate / 药学学报

As a member of the human epidermal growth factor receptor (HER) family of receptor tyrosine kinases, HER3 is an aberrantly activator of the PI3K/AKT pathway. Studies have indicated that HER3 is related to the progression of a variety of tumor types such as breast cancer, non-small cell lung cancer (NSCLC), ovary cancer and colon cancer, and in acquired resistance to EGFR and HER2 therapies. However, the attempts to target HER3 with neutralizing antibodies are not ideal previously. This is most likely due to the fact that the antibodies targeting HER3 fail to completely block the heterodimerization of HER3 and other receptors. Antibody-drug conjugates (ADCs) can specifically bind to target cells and exert the highly cytotoxicity effect on cancer cells through chemical drugs. ADCs have been widely used in clinical cancer therapies. We analyzed and optimized the structure of the antigen-antibody complex between HER3 and antibody LmAb3 by computer-aided molecular simulation technology, and the key sites involved in antigen binding in LmAb3 were predicted by distance geometry and computer graphics technology. Then a novel anti-HER3 antibody FD001 was obtained by point mutation technology. The affinity measurement by ForteBio results showed that the affinity of FD001 is much higher than LmAb3, the KD values of FD001 and LmAb3 with HER3 were 1.48E-11 and 2.46E-10, respectively. Antibody drug conjugate FD001-DM1 is obtained by coupling FD001 to DM1 [emtansine, N2'-deacetyl-N2'-(3-mercapto-1-oxopropyl)-maytansine] by lysine coupling technology. The results of cell cytotoxicity experiments showed that FD001-DM1 could effectively inhibit the proliferation of HER3-positive HT-29 colon cancer cells, with EC50 value of 33.62 nmol·L-1. The in vivo xenografts therapy results showed that the tumor volume of the FD001-DM1 treatment group was about 25% of that of the control group, and there was no significant weight reduction of the mice. These results reveal that FD001-DM1 had good in vivo and in vitro anti-tumor activity with high safety, which may provide effective help for further exploration of HER3-targeted ADCs drugs. The mice in this study were used and treated in accordance with international laboratory animal care and use guidelines and approved by the Animal Ethics Committee of the Military Cognitive and Brain Science Institute of the Military Medical Research Institute.

Anti-tumor activity of novel targeting HER2 antibody-drug conjugates / 药学学报

Antibody-drug conjugates (ADCs) are widely used in cancer treatment. Human epidermal growth factor receptor-2 (HER2) is overexpressed in various types of solid tumors and is a validated therapeutic target for cancers. To develop a more effective therapy, we generated a novel anti-HER2 humanized monoclonal antibody MIL40 and MIL40 drug conjugates as novel cancer therapies. The MIL40 was conjugated with small molecule cytotoxic agents DM1 [emtansine, N2'-deacetyl-N2'-(3-mercapto-1-oxopropyl)-maytansine] or monomethylauristatin E (MMAE) to generate ADCs, which were evaluated for their in vitro and in vivo anti-cancer activities. Experimental results show that MIL40-DM1 and MIL40-MMAE can effectively identify and bind to HER2-positive tumor cells. The binding capabilities of MIL40-DM1 and MIL40-MMAE with HER2 extracellular domain (ECD) antigens were not different after conjugation with DM1 or MMAE. The ADCs showed potent cytotoxicity in HER2-positive ovarian cancer cells SKOV3, breast cancer cells SKBR3 and stomach cancer cells N87 in vitro. MIL40-DM1 can effectively inhibit the volume and weight growth of SKOV3 transplant tumors in mice. The mice in this study were used and treated by following the international guidelines for the care and use of laboratory animals, and approved by Animal Ethics Committee of Institute of Military Cognitive and Brain Sciences.

Correlation between the primary tumor size of endometrial carcinoma and lymph node metastasis and recurrence / 中华妇产科杂志

Objective:To investigate the clinical significance of the primary tumor size in patients with endometrial carcinoma (EC).Methods:A total of 385 patients with EC admitted to Peking University People's Hospital from January 2006 to December 2016 with complete follow up data were selected, whose tumor size data before biopsy were retrospectively studied.Results:(1) The mean diameter of the primary tumor was (3.6±1.8) cm (range: 1-15 cm). And 48 cases were 0-<2 cm, 78 cases were 2-<3 cm, 92 cases were 3-<4 cm, 73 cases were 4-<5 cm, 94 cases were ≥5 cm. The diameter of the tumor was associated with age <60 years old, premenopause, CA 125≥35 kU/L, non-parturition, poor differentiation, stage Ⅲ-Ⅳ, depth of myometrial infiltration ≥1/2, cervical interstitial involvement, adnexal metastasis and lymph node metastasis (all P<0.05), but not associated with body mass index, hypertension, diabetes mellitus, pathology, lymph-vascular space invasion (all P>0.05). (2) Among the 334 patients underwent lymphadenectomy, 45 (13.5%, 45/334) cases with lymph node metastasis were observed. Stratified analysis showed that lymph node metastasis and recurrence rate of patients with EC gradually increased with the increase of tumor size ( P<0.05). Adopting 2, 3, 4 and 5 cm as cut-off values of tumor size, there were significant differences in the rate of lymph node metastasis and recurrence among them observed ( P<0.05), except for lymph node metastasis rate and recurrence rate when the cut-off value was 2 cm ( P>0.05). (3) An receiver operating characteristic (ROC) curve analysis showed that a tumor diameter of 4.25 cm was the cut-off prognostic value to predict lymph node metastasis and recurrence of EC. Conclusions:Tumor diameter is significantly correlated with lymph node metastasis and recurrence in patients with EC. Tumor size should be considered in determining the scope of surgery and adjuvant therapy.

Dissolution, absorption and bioaccumulation in gastrointestinal tract of mercury in HgS-containing traditional medicines Cinnabar and Zuotai / 中国中药杂志

α-HgS is the main component of traditional Chinese medicine cinnabar, while β-HgS is the main component of Tibetan medicine Zuotai. However, there was no comparative study on the dissolution and absorption in gastrointestinal tract and bioaccumulation in organs of mercury in Cinnabar, Zuotai, α-HgS and β-HgS. In this study, the dissolution process of the four compounds in the human gastrointestinal tract was simulated to determine the mercury dissolutions and compare the mercury dissolution of different medicines and the dissolution-promoting capacity of different solutions. To explore the absorption and bioaccumulation of cinnabar and Zuotai in organisms, mice were orally administered with clinical equivalent doses cinnabar and Zuotai. Meanwhile, a group of mice was given α-HgS and β-HgS with the equivalent mercury with cinnabar, while another group was given β-HgS and HgCl2 with the equivalent mercury with Zuotai. The mercury absorption and bioaccumulation capacities of different medicines in mice and their mercury bioaccumulation in different tissues and organs were compared. The experimental results showed a high mercury dissolutions of Zuotai in artificial gastrointestinal fluid, which was followed by β-HgS, cinnabar and α-HgS. As for the mercury absorption and bioaccumulation in mice, HgCl2 was the highest, β-HgS was the next, and a-HgS was slightly higher than cinnabar. The organs with the mercury bioaccumulation from high to low were kidney, liver and brain. This study is close to clinical practices and can provide reference for the clinical safe medication as well as a study model for the safety evaluation on heavy metal-containing medicines by observing the mercury dissolution, absorption, distribution and accumulation of mercury-containing medicines cinnabar and zuotai.
