Project description:IntroductionYS110, a humanized monoclonal antibody with a high affinity to CD26, exhibited promising antitumor activity and was generally well-tolerated in the phase 1 part of a phase 1 and 2 Japanese trial in patients with malignant pleural mesothelioma (MPM). Here we report the results of the phase 2 part of the study.MethodsThe patients included were aged 20 years and older, had histologically confirmed MPM, were refractory to or intolerant of existing antineoplastic agents, and were not candidates for standard therapy. YS110 6 mg/kg, determined in the phase 1 dose-determination part, was given in 6-weekly cycles (5 × once-weekly infusions, followed by a 1-wk rest).ResultsThe study included 31 patients (median age = 68 y, 90.3% men); 64.5% had stage IV MPM, 90.3% had greater than or equal to 20% CD26 expression in tumor tissue, and 38.7% (12 patients) had previously received nivolumab. The 6-month disease control rate was 3.2%. The best overall response was partial response in one patient and stable disease in 14 patients. The median progression-free survival was 2.8 months (both in patients who had and had not previously received nivolumab-groups A and B, respectively). Respective progression-free survival rates at 6 months were 9.1% and 31.6% in groups A and B. The median overall survival was 9.7 months. A total of 30 patients (96.8%) had at least one adverse event. Common treatment-related adverse events were infusion-related reaction (16.1%), hiccups (9.7%), and interstitial lung disease (9.7%). There were no treatment-related deaths.ConclusionsThe 6-month disease control rate did not exceed the predefined threshold, but YS110 revealed modest efficacy in response rate as salvage therapy in difficult-to-treat patients with MPM. YS110 was generally well tolerated.

Project description:Current chemotherapy regimens have certain limitations in improving the survival rates of patients with advanced ovarian cancer. Hepatocyte growth factor (HGF) is important in ovarian cancer cell migration and invasion. This study assessed the effects of YYB-101, a humanized monoclonal anti-HGF antibody, on the growth and metastasis of ovarian cancer cells. YYB-101 suppressed the phosphorylation of the HGF receptor c-MET and inhibited the migration and invasion of SKOV3 and A2780 ovarian cancer cells. Moreover, the combination of YYB-101 and paclitaxel synergistically inhibited tumor growth in an in vivo ovarian cancer mouse xenograft model and significantly increased the overall survival (OS) rate compared with either paclitaxel or YYB-101 alone. Taken together, these findings suggest that YYB-101 has therapeutic potential in ovarian cancer when combined with conventional chemotherapy agents.

Project description:Veltuzumab is a humanized anti-CD20 monoclonal antibody with complementarity-determining regions (CDRs) identical to rituximab, except for one residue at the 101st position (Kabat numbering) in CDR3 of the variable heavy chain (V(H)), having aspartic acid (Asp) instead of asparagine (Asn), with framework regions of epratuzumab, a humanized anti-CD22 antibody. When compared with rituximab, veltuzumab has significantly reduced off-rates in 3 human lymphoma cell lines tested, as well as increased complement-dependent cytotoxicity in 1 of 3 cell lines, but no other in vitro differences. Mutation studies confirmed that the differentiation of the off-rate between veltuzumab and rituximab is related to the single amino acid change in CDR3-V(H). Studies of intraperitoneal and subcutaneous doses in mouse models of human lymphoma and in normal cynomolgus monkeys disclosed that low doses of veltuzumab control tumor growth or deplete circulating or sessile B cells. Low- and high-dose veltuzumab were significantly more effective in vivo than rituximab in 3 lymphoma models. These findings are consistent with activity in patients with non-Hodgkin lymphoma given low intravenous or subcutaneous doses of veltuzumab. Thus, changing Asn(101) to Asp(101) in CDR3-V(H) of rituximab is responsible for veltuzumab's lower off-rate and apparent improved potency in preclinical models that could translate into advantages in patients.

Project description:PurposeRC48 contains the novel humanized anti-HER2 antibody hertuzumab conjugated to MMAE via a cleavable linker. A phase I study was initiated to evaluate the toxicity, MTD, PK, and antitumor activity of RC48 in patients with HER2-overexpressing locally advanced or metastatic solid carcinomas, particularly gastric cancer.Patients and methodsThis was a 2-part phase I study. Successive cohorts of patients received escalating doses of RC48 (0.1 mg/kg, 0.5 mg/kg, 1.0 mg/kg, 2.0 mg/kg, 2.5 mg/kg, and 3.0 mg/kg). Dose expansion proceeded at the dose of 2.0 mg/kg Q2W. The efficacy and safety set included all patients who received at least one dose of RC48.ResultsFifty-seven patients were enrolled, the MTD was unavailable due to termination of 3.0 mg/kg cohort; 2.5 mg/kg Q2W was declared the RP2D. RC48 was well tolerated, the most frequent grade 3 or worse TRAEs included neutropenia (19.3%), leukopenia (17.5%), hypoesthesia (14.0%), and increased conjugated blood bilirubin (8.8%). Four deaths occurred during the whole study, three of which were believed to be related to RC48. Overall, ORR and DCR were 21.0% (12/57) and 49.1% (28/57). Notably, patients who were HER2 IHC2+/FISH- responded similarly to those who were IHC2+/FISH+ and IHC3+, with ORRs of 35.7% (5/14), 20% (2/10), and 13.6% (3/22), respectively. In patients who were pretreated with HER2-targeted drugs, RC48 also showed promising efficacy, with ORR of 15.0% (3/20) and DCR of 45.0% (9/20).ConclusionRC48 was well tolerated and showed promising antitumor activity in HER2-positive solid tumors, including gastric cancer with HER2 IHC 2+/FISH- status.Clinical trial informationNCT02881190.

Project description:Neuroinflammation is a crucial process for the loss of retinal ganglion cells (RGC), a major characteristic of glaucoma. High expression of high mobility group box protein 1 (HMGB1) plays a detrimental role in inflammatory processes and is elevated in the retinas of glaucoma patients. Therefore, this study aimed to investigate the effects of intravitreal injection of an anti-HMGB1 monoclonal antibody (anti-HMGB1 Ab) in an experimental animal model of glaucoma. Two groups of Spraque Dawley rats received episcleral vein occlusion to chronically elevate intraocular pressure (IOP): (1) IgG group, intravitreal injection of an unspecific IgG as a control, n=5, (2) HMGB1 group, intravitreal injection of an anti-HMGB1 Ab, n=6. IOP, retinal nerve fiber layer thickness (RNFLT), and the retinal flash response was monitored longitudinally. Post-mortem examinations included immunohistochemistry, microarray, and mass spectrometric analysis. RNFLT was significantly increased in the HMGB1 group compared to the IgG group (p<0.001). RGC density showed improved neuronal cell survival in the retina in HMGB1 compared to the IgG group (p<0.01). Mass spectrometric proteomic analysis of retinal tissue showed increased abundance of RNA metabolism-associated heterogeneous nuclear ribonucleoproteins (hnRNPs), such as hnRNP U, D, and H2, in animals injected with the anti-HMGB1 Ab, indicating that application of the antibody may cause increased gene expression. Microarray analysis showed significantly decreased expression of C-X-C motif chemokine ligand 8 (CXCL8, p<0.05) and connective tissue growth factor (CTGF, p<0.01) in the HMGB1 group. Thus, these data suggest that intravitreal injection of anti-HMGB1 Ab reduced HMGB1-dependent inflammatory signaling and mediated RGC neuroprotection.

Project description:Antibodies are commonly used in cancer immunotherapy because of their high specificity for tumor-associated antigens. The binding of antibodies can have direct effects on tumor cells but also engages natural killer (NK) cells via their Fc receptor. Mucin 1 (MUC1) is a highly glycosylated protein expressed in normal epithelial cells, while the under-glycosylated MUC1 epitope (MUC1-Tn/STn) is only expressed on malignant cells, making it an interesting diagnostic and therapeutic target. Several anti-MUC1 antibodies have been tested for therapeutic applications in solid tumors thus far without clinical success. Herein, we describe the generation of fully humanized antibodies based on the murine 5E5 antibody, targeting the tumor-specific MUC1-Tn/STn epitope. We confirmed that these antibodies specifically recognize tumor-associated MUC1 epitopes and can activate human NK cells in vitro. Defucosylation of these newly developed anti-MUC1 antibodies further enhanced antigen-dependent cellular cytotoxicity (ADCC) mediated by NK cells. We show that endocytosis inhibitors augment the availability of MUC1-Tn/STn epitopes on tumor cells but do not further enhance ADCC in NK cells. Collectively, this study describes novel fully humanized anti-MUC1 antibodies that, especially after defucosylation, are promising therapeutic candidates for cellular immunotherapy.

Project description:Purpose This study aimed to evaluate the safety and pharmacokinetic (PK) profiles of HLX07, a novel, recombinant, humanized anti-epidermal growth factor receptor (EGFR) antibody, in patients with advanced solid cancers who had failed standard therapy or for whom no standard therapy was available. Methods In this prospective, open-label, Phase I dose escalation study, patients aged ≥18 years (≥20 years for patients in Taiwan) with histologically-confirmed metastatic or recurrent epithelial carcinoma that had no K-RAS or B-RAF mutations were enrolled in a '3 + 3' escalation design. HLX07 was administered weekly by 2-h intravenous infusion at doses ranging from 50 to 800 mg. The primary endpoint was summary listing of participants reporting treatment-emergent adverse events (TEAEs). Secondary endpoints included PK analysis, serum anti-HLX07 antibody assessments and efficacy. Results In total, 19 patients were enrolled between 1 October 2016 and 16 July 2019 to receive HLX07 at doses of 50 (n = 3), 100 (n = 3), 200 (n = 3), 400 (n = 3), 600 (n = 3) and 800 (n = 4) mg per week. All patients experienced at least one TEAE, most commonly fatigue (68.4%), nausea (47.4%), paronychia (31.6%) and vomiting (31.6%). Serious TEAEs were reported in 11 patients but only one serious TEAE (dyspnea in 600 mg cohort) was regarded as possibly related to study treatment. No dose limiting toxicity (DLT) was reported. Systemic exposure to HLX07 increased proportionally with dose. Anti-HLX07 antibodies were not detected in any patients. Conclusion HLX07 was well tolerated (at dose levels up to 800 mg/week) and promising in patients with advanced solid cancers.Clinical Trial Registration: The study was registered at ClinicalTrials.gov : NCT02648490 (Jan 7, 2016).
