ABSTRACT

BACKGROUND: The programmed death 1 inhibitor toripalimab plus the angio-immuno kinase inhibitor surufatinib revealed a tolerable safety profile and preliminary efficacy in patients with advanced solid tumours in a phase I study. PATIENTS AND METHODS: This was an open-label, single-arm, multi-cohort phase II study in China. Patients with advanced neuroendocrine tumours (NETs) or neuroendocrine carcinomas (NECs) or mixed neuroendocrine non-neuroendocrine neoplasms (MiNENs) who had failed or were intolerable of standard treatment were given surufatinib (250 mg orally, once daily) plus toripalimab (240 mg intravenously, once every 3 weeks). Primary end-point was investigator-assessed objective response rate (ORR) per Response Evaluation Criteria in Solid Tumors version 1.1. Secondary end-points included duration of response (DoR), disease control rate, progression-free survival (PFS), overall survival (OS), and safety. RESULTS: Forty patients were enrolled into two cohorts by tumour types (NET, n = 19; NEC-MiNEN, n = 21). ORRs (95% CIs) were 21.1% (6.1-45.6) and 23.8% (8.2-47.2) in the NET and NEC-MiNEN cohorts, respectively. Median DoR was 7.1 months (6.9-not evaluable [NE]) and 4.1 months (3.0-NE), respectively. Median PFS was 9.6 months (4.1-NE) and 4.1 months (1.5-5.5); median OS was 27.3 (15.3-NE) and 10.9 months (9.1-14.6), respectively. Overall, grade ≥ 3 treatment-related adverse events occurred in 18 (45.0%) patients. CONCLUSIONS: Surufatinib plus toripalimab showed antitumour activity and a tolerable safety profile in patients with previously treated NETs/NECs/MiNENs. Further study of this combination regimen is ongoing for advanced NECs, for which current therapeutic options remain limited. CLINICALTRIALS: gov: NCT04169672.

ABSTRACT

Objective: The aim of this study is to explore the value of combined detection of ABO blood group and tumor markers in the diagnosis of gastric cancer. Methods: A total of 3650 gastric cancer patients treated in our center from January 2015 to December 2019, and 5822 controls were recruited, and divided into training set and validation set according to 7:3. The diagnostic and predictive model of gastric cancer was constructed by binary logistic regression method in the training set. The diagnostic value of the prediction model for gastric cancer was evaluated by calculating the prediction probability P value and drawing the Receiver operating characteristic (ROC) curve, and was verified in the validation set. Results: The Area under the curve (AUC) of the diagnosis and prediction model in the training set was 0.936 (95%CI: 0.926-0.941), the sensitivity was 81.66%, and the specificity was 98.61%. In the validation set, the AUC was 0.941 (95%CI: 0.932-0.950), the sensitivity was 82.33%, and the specificity was 99.02%. Furthermore, the diagnostic model obtained in this study had a high diagnostic value for early gastric cancer patients in the healthy population (AUC of training set, validation set and total population were 0.906, 0.920 and 0.908, respectively). Conclusions: We constructed a diagnostic model for gastric cancer including blood group and tumor markers, which has high reference value for the diagnosis of gastric cancer patients, and the model can better distinguish early gastric cancer from healthy people.

ABSTRACT

BACKGROUND: With the development of traditional Chinese medicine research, berberine has shown good efficacy and safety in the eradication of Helicobacter pylori (H. pylori). The present study aimed to evaluate the efficacy and safety of triple therapy containing berberine, amoxicillin, and vonoprazan for the initial treatment of H. pylori. METHODS: This study was a single-center, open-label, parallel, randomized controlled clinical trial. Patients with H. pylori infection were randomly (1:1:1) assigned to receive berberine triple therapy (berberine 500 mg, amoxicillin 1000 mg, vonoprazan 20 mg, A group), vonoprazan quadruple therapy (vonoprazan 20 mg, amoxicillin 1000 mg, clarithromycin 500 mg, colloidal bismuth tartrate 220 mg, B group), or rabeprazole quadruple therapy (rabeprazole 10 mg, amoxicillin 1000 mg, clarithromycin 500 mg, colloidal bismuth tartrate 220 mg, C group). The drugs were taken twice daily for 14 days. The main outcome was the H. pylori eradication rate. The secondary outcomes were symptom improvement rate, patient compliance, and incidence of adverse events. Furthermore, factors affecting the eradication rate of H. pylori were further analyzed. RESULTS: A total of 300 H. pylori-infected patients were included in this study, and 263 patients completed the study. An intention-to-treat (ITT) analysis showed that the eradication rates of H. pylori in berberine triple therapy, vonoprazan quadruple therapy, and rabeprazole quadruple therapy were 70.0% (70/100), 77.0% (77/100), and 69.0% (69/100), respectively. The per-protocol (PP) analysis showed that the eradication rates of H. pylori in these three groups were 81.4% (70/86), 86.5% (77/89), and 78.4% (69/88), respectively. Both ITT analysis and PP analysis showed that the H. pylori eradication rate did not significantly differ among the three groups (P >0.05). In addition, the symptom improvement rate, overall adverse reaction rate, and patient compliance were similar among the three groups (P >0.05). CONCLUSIONS: The efficacy of berberine triple therapy for H. pylori initial treatment was comparable to that of vonoprazan quadruple therapy and rabeprazole quadruple therapy, and it was well tolerated. It could be used as one choice of H. pylori initial treatment.

ABSTRACT

BACKGROUND: Senaparib, a novel poly(ADP-ribose) polymerase 1/2 inhibitor, demonstrated antitumor activity in preclinical studies. This phase I, first-in-human, dose-escalation/-expansion study explored the pharmacokinetics, safety and tolerability, and preliminary antitumor activity of senaparib in Chinese patients with advanced solid tumors. PATIENTS AND METHODS: Adults with advanced solid tumors who had failed ³1 line of prior systemic treatment were enrolled. Senaparib (once daily [QD]) dose was escalated from 2 mg until the maximum tolerated dose (MTD)/recommended phase II dose (RP2D) using a modified 3 + 3 design. Dose expansion included: dose groups with ≥1 objective response and one dose higher, as well as those at the MTD/RP2D. Primary objectives were to evaluate the safety and tolerability, and determine the MTD and/or RP2D of senaparib. RESULTS: Fifty-seven patients were enrolled across 10 dose groups (2-120 mg QD, and 50 mg twice daily). No dose-limiting toxicities were observed. The most common senaparib-related adverse events were anemia (80.9%), white blood cell count decreased (43.9%), platelet count decreased (28.1%), and asthenia (26.3%). Senaparib exposure increased dose proportionately at 2-80 mg; absorption saturated at 80-120 mg. Senaparib accumulation was minimal after repeated QD administration (accumulation ratio=1.1-1.5). The objective response rate was 22.7% (n=10/44) overall (all partial responses) and 26.9% (n=7/26) for patients harboring BRCA1/BRCA2 mutations. Disease control rates were 63.6% and 73.1%, respectively. CONCLUSIONS: Senaparib was well tolerated and demonstrated promising antitumor activity in Chinese patients with advanced solid tumors. The RP2D for this clinical study in China was identified as 100 mg QD. CLINICALTRIALS.GOV IDENTIFIER: NCT03508011.

ABSTRACT

Serologic biomarker to predict clinical outcome is needed for immune checkpoint inhibitors (ICIs). We evaluated soluble intercellular adhesion molecules-1 (sICAM-1) as a predictor of response to ICIs treatment. Ninety-five patients with cancer treated with ICI were studied. The serum sICAM-1 levels of baseline, post two cycle therapy and end of therapy (EOT) were measured by enzyme-linked immunoassay. We randomly assigned the patients into the primary cohort (n = 47) and validation cohort (n = 48). Serum sICAM-1 post two cycle (277.7 ± 181.6 ng/mL) and EOT (403.9 ± 218.9 ng/mL) were significantly elevated compared to baseline (244.8 ± 153.8 ng/mL, p = 0.008 and p = 0.004, respectively). Early changes of sICAM-1 (ΔsICAM-1), deemed as sICAM-1 after two cycles minus baseline, were assessed. Following ICI treatments, responders had significantly lower ΔsICAM-1 compared with nonresponders in the primary cohort (p = 0.040) and the validation cohort (p = 0.026). High ΔsICAM-1 was strongly associated with inferior progression-free survival (PFS; (primary cohort: p = 0.001 and validation cohort: p = 0.002) and overall survival (OS; (primary cohort: p < 0.001 and validation cohort: p = 0.007). The ΔsICAM-1 remained independently associated with worse PFS and OS in the primary cohort and the validation cohort. Subgroup analysis indicated patients whose sICAM-1 significantly elevated had shorter PFS and OS in both anti-PD-1 and anti-PD-L1 treatment groups. Early change of serum sICAM-1 could be used to monitor and predict clinical benefit of ICI therapy in patients with solid cancer.

ABSTRACT

BACKGROUND AND OBJECTIVE: The development of epigenetics holds great promise for diagnosis and treatment of lung adenocarcinoma (LUAD). The purpose of this work was to analyze the correlation between Ras Homolog Gene Family Member H (RHOH) expression and methylation in patients with LUAD and its association with survival. METHODS: Data related to gene expression, DNA methylation, and clinical features of LUAD from The Cancer Genome Atlas (TCGA) database were analyzed. A total of 50 patients were included in verification group. The methylation level of RHOH in verification group was detected by bisulfite amplicon sequencing. RESULTS: The RHOH methylation level in TCGA cohort was significantly and negatively correlated with its expression level (Cor = -0.5, p = 2.687e-33). Patients with hypermethylation and low expression of RHOH had significantly worse prognosis than patients with hypomethylation and low expression of RHOH (TCGA: p = 0.004; validation cohort: p = 0.006, HR: 4.740, 95% CI: 1.567-14.340). CONCLUSION: Our research revealed that RHOH may prove to be a new potential prognostic predictor for LUAD patients.

ABSTRACT

PURPOSE: ARX788 is a novel antibody-drug conjugate (ADC) comprised of an anti-HER2 mAb and a potent tubulin inhibitor payload AS269 that is site-specifically conjugated to the antibody via a nonnatural amino acid incorporated into the antibody. Herein, we present the results of a phase I study of the safety, pharmacokinetics, and antitumor activity of ARX788 in patients with HER2-positive metastatic breast cancer (MBC). PATIENTS AND METHODS: Patients with HER2-positive MBC received ARX788 at doses of 0.33, 0.66, 0.88, 1.1, 1.3, or 1.5 mg/kg every 3 weeks, or 0.88, 1.1, or 1.3 mg/kg every 4 weeks. The dose-limiting toxicity (DLT) was assessed for 84 days for pulmonary toxicity and at a duration of one cycle (21 or 28 days) for other toxicities. RESULTS: In total, 69 patients were enrolled. No DLT or drug-related deaths occurred. Most patients (67/69; 97.1%) experienced at least one treatment-related adverse event (TRAE). Common (≥ 30%) TRAEs included an increase in aspartate aminotransferase, an increase in alanine aminotransferase, corneal epitheliopathy, alopecia, hypokalemia, interstitial lung disease (ILD)/pneumonitis, and an increase in aldosterone. While 34.8% of participants experienced ILD/pneumonitis, only 2 had a severity of grade 3. At 1.5 mg/kg every 3 weeks, the recommended phase II dose, the objective response rate was 65.5% [19/29, 95% confidence interval (CI), 45.7-82.1], the disease control rate was 100% (95% CI, 81.2-100), and the median progression-free survival was 17.02 months (95% CI, 10.09-not reached). CONCLUSIONS: ARX788 demonstrated a manageable safety profile with promising preliminary signs of activity in patients with HER2-positive MBC who progressed on prior anti-HER2 therapies.

ABSTRACT

PURPOSE: KN026 is a novel bispecific antibody that simultaneously binds to two distinct HER2 epitopes. This first-in-human phase I study evaluated the safety/tolerability, pharmacokinetics, preliminary efficacy, and potential predictive biomarker activity of KN026 administered as monotherapy to patients with HER2-positive metastatic breast cancer (MBC). PATIENTS AND METHODS: Female patients with HER2-positive MBC who had progressed on prior anti HER2 therapies received intravenous KN026 monotherapy at 5 mg/kg (once weekly), 10 mg/kg (once weekly), 20 mg/kg (once every 2 weeks), or 30 mg/kg (once every 3 weeks). Dose escalation was guided by a "3+3" dose escalation rule followed by dose expansion. RESULTS: Sixty-three patients were enrolled. The most common treatment-related adverse events (TRAE) were pyrexia (23.8%), diarrhea (22.2%), aspartate aminotransferase increased (22.2%), alanine aminotransferase increased (22.2%). Only 4 patients reported grade 3 TRAEs. Results from exposure-response analysis supported the selection of the recommended phase II doses at 20 mg/kg once every 2 weeks or 30 mg/kg once every 3 weeks, which had objective response rates (ORR) of 28.1% and median progression-free survival (PFS) of 6.8 months (95% confidence interval: 4.2-8.3) in 57 patients. Translational research in 20 HER2-amplified patients further confirmed that co-amplification (vs. no co-amplification) of CDK12 was a promising biomarker in predicting better response to KN026 (ORR of 50% vs. 0% and median PFS of 8.2 vs. 2.7 months, P = 0.05 and 0.04, respectively). CONCLUSIONS: KN026, a HER2 bispecific antibody, was well tolerated and achieved comparable efficacy as trastuzumab and pertuzumab doublet even in the more heavily pretreated patients. Co-amplification of HER2/CDK12 may define patients who benefit more from KN026.

ABSTRACT

BACKGROUND: Abemaciclib, a cyclin-dependent kinase 4 and 6 inhibitor, is approved in combination with endocrine therapy or as monotherapy for hormone receptor-positive and human epidermal growth factor receptor-2-negative (HR+/HER2-) advanced breast cancer outside of China. OBJECTIVE: To evaluate the safety, tolerability, and pharmacokinetic (PK) profile of abemaciclib in Chinese patients with advanced and/or metastatic cancers. PATIENTS AND METHODS: A multicenter, open-label, phase I trial of abemaciclib in Chinese patients with advanced and/or metastatic cancers was conducted. Patients were randomized (1:1) to oral abemaciclib 150 or 200 mg every 12 h on a 28-day cycle. Safety analyses (primary outcome) included all patients receiving at least one dose of abemaciclib. PK and antitumor activity were also assessed. RESULTS: Of the 26 patients randomized, 25 received abemaciclib 150 mg (n = 12) or 200 mg (n = 13). All 25 patients reported ≥ 1 treatment-emergent adverse event (TEAE). The majority of TEAEs were Common Terminology Criteria for Adverse Events (CTCAE) Grade 1 or 2 in severity. The most frequent TEAEs of Grade ≥ 3 were neutropenia (32%) and thrombocytopenia (24%). Four patients (16%) discontinued treatment due to AEs. Abemaciclib exhibited slow absorption and clearance at single dose, with maximum concentrations achieved after around 6 h and an elimination half-life of approximately 24 h. No complete response was observed, two patients (8%) achieved partial response, with one confirmed responder, and the disease control rate was 68% (n = 17). CONCLUSIONS: Abemaciclib was well tolerated and the safety and PK profiles in Chinese patients were comparable to those previously reported in non-Chinese populations. Preliminary antitumor activity was observed. CLINICALTRIALS. GOV IDENTIFIER: NCT02919696.

ABSTRACT

BACKGROUND: Trastuzumab emtansine (T-DM1) is an antibody-drug conjugate that retains the antitumor effects of trastuzumab while also delivering the cytotoxic antimicrotubule agent, DM1, directly to tumor cells that overexpress human epidermal growth factor receptor 2. The pharmacokinetic (PK) profile of T-DM1 has been well characterized in Western, Asian, and Japanese patients; this single-center, phase I study (NCT03153163) examined the PK of T-DM1 and safety specifically in Chinese patients. METHODS: Patients with locally advanced or metastatic breast cancer, previously treated with trastuzumab and a taxane, received open-label T-DM1 at 3.6 mg/kg every 3 weeks. Serum T-DM1 and total trastuzumab, and plasma DM1 were evaluated, and PK parameters were calculated using standard noncompartmental approaches. Adverse events (AEs) were assessed, and immunogenicity was evaluated by measuring antidrug antibodies to T-DM1. RESULTS: Among 11 Chinese patients, mean (±standard deviation) PK parameters (maximum serum concentration, 77.6 ±â€Š17.4 µg/mL; clearance 11.0 ±â€Š2.6 mL/d/kg; terminal half-life 3.8 ±â€Š1.0 days) were similar to those previously reported in Western and Japanese patients. One patient transiently developed antidrug antibodies, which did not appear to influence safety or PK. T-DM1 was generally well tolerated. Grade 3-4 AEs occurred in 7 patients (63.6%) and serious AEs occurred in 4 patients (36.4%). Platelet count decrease was the most common all-grade AE (10/11; 90.9%), grade 3-4 AE (5/11; 45.5%), and serious AE (3/11; 27.3%), but did not appear to be associated with any clinically significant bleeding events. CONCLUSIONS: T-DM1 PK in Chinese patients was consistent with those in global and Asian populations, supporting its use in patients with advanced human epidermal growth factor receptor 2-positive breast cancer following progression on trastuzumab and a taxane. The safety profile of T-DM1 was consistent with prior experience.

ABSTRACT

LESSONS LEARNED: Ramucirumab was well tolerated in Chinese patients with advanced solid tumors, and adverse events were manageable in this study.Pharmacokinetics characteristics in Chinese patients were similar to those in other populations. Immunogenicity was not detected.No efficacy conclusion could be drawn, and further randomized studies are warranted. BACKGROUND: This single-arm, nonrandomized, open-label, dose-escalation, phase I study was designed to evaluate the safety, tolerability, and pharmacokinetics (PK) of ramucirumab in Chinese patients with advanced solid tumors that were resistant to standard therapy or no standard therapy was available. METHODS: Dose escalation was a 3 + 3 design, with expansion in Cohorts 2 and 3 for PK. Ramucirumab was given intravenously at three different dosages: 6 mg/kg every 2 weeks, 10 mg/kg every 3 weeks, and 8 mg/kg every 2 weeks. Safety analyses included all patients. PK, immunogenicity, and antitumor activity were also assessed. RESULTS: Among 28 patients treated, 2 experienced dose-limiting toxicity, possibly related to ramucirumab. No maximum tolerated dose was determined. All patients experienced at least one treatment-emergent adverse event. Grade ≥3 adverse event was reported for 53.6% (n = 15) of patients. PK analyses indicated that ramucirumab had low clearance, small volume of distribution, and long half-life in Chinese patients, as in other populations. Immunogenicity was not detected. No patient had complete/partial response, and 64.3% (n = 18) had stable disease with a median duration of 5.55 months (95% confidence interval: 3.38-7.13 months). CONCLUSION: Ramucirumab appeared to be well tolerated in Chinese patients with advanced solid tumors. PK characteristics in Chinese patients were similar to those in other populations.

ABSTRACT

OBJECTIVE: The aim of this study was to compare the safety and efficacy profiles of R-CHOP and R-fCHOP regimes in the treatment of primary gastric diffuse large B cell lymphoma (PG-DLBCL). METHODS: Data of PG-DLBCL patients admitted in our hospital from March 2010 to March 2014 were collected retrospectively. Differences in gastrointestinal bleeding and perforation between the R-CHOP group and R-fCHOP group were compared. The influence of the gastrointestinal complication on subsequent treatment was also analyzed. Treatment outcome of the two groups was also compared. RESULTS: A total of 50 patients were included in this retrospective study. Forty of them were in the R-CHOP group, another ten were in the R-fCHOP group. Patients in the R-fCHOP group had a higher rate of Lugano late stage disease, and a relatively high rate of a deeper/larger ulcer. Fence occult blood test (FOBT) was positive in one (10.0%) patient in the R-fCHOP group, and 11 (31.4%) patients in the R-CHOP group, among them one had hematemesis and had to give up the subsequent chemotherapy. No perforation was observed in both groups. The response rate (RR) was 92.5% in the R-CHOP group and 90.0% in the R-fCHOP group (P > 0.05). The PFS was also comparable between the two groups (P > 0.05). CONCLUSIONS: R-fCHOP regimen has a good safety profile in patients with Lugano late stage and deep/large ulcers, who are of high risk of gastrointestinal bleeding or perforation, and also has a comparable efficacy profile when compared with the R-CHOP regimen in short-term follow-up.

ABSTRACT

Gastrointestinal diffuse large B cell lymphoma (DLBCL) is a common subtype of extranodal lymphoma. There has been uncertainty about the clinical efficacy of combination therapy (surgery and chemotherapy) for gastrointestinal DLBCL. We retrospectively analyzed 114 patients with newly diagnosed gastrointestinal DLBCL from six medical centers. We evaluated four groups based on whether they were treated with or without surgery as the initial treatment for DLBCL, followed by either a regimen with cyclophosphamide, vincristine, doxorubicin, and prednisone (CHOP) or CHOP with rituximab (R-CHOP). For all patients, treatment with R-CHOP resulted in significantly greater overall survival (OS; 93.2 vs. 74.5%, p = 0.008) and progression-free survival (89.8% vs. 72.7, p = 0.029). Tumor resection did not improve OS (84.0 vs. 85.0%, for surgery and chemotherapy alone, respectively, p = 0.980). However, for younger patients, overall survival was greater (p = 0.005) for patients treated with surgery plus chemotherapy (83.9%) than for patients treated with chemotherapy alone (40.0%). Elevated serum lactate dehydrogenase level (p = 0.004) and performance status (Eastern Cooperative Oncology Group; p = 0.003) were independent predictors of survival in patients with gastrointestinal DLBCL. Stage-modified IPI was recognized as the best prognostic tool. There were significant differences among patients with low-risk, intermediate-risk, and high-risk groups in 50-month OS (94.2 vs. 84.0 vs. 66.7%, p = 0.008). The results of this large-scale study suggest that R-CHOP regimen is the first-line treatment for gastrointestinal DLBCL. The benefit of surgery for these patients remains controversial. Further prospective analyses are warranted.
