All patients were treated with TACE. All patients were treated with C-TACE. The treatment times of TACE were determined according to the changes of liver function and tumor volume.
Sorafenib (Bayer HealthCare AG, 200 mg/pill) was initially prescribed at 400–800 mg/day after one week after TACE, and with tumor progression, regorafenib replaced Sorafenib. regorafenib was administered orally within one week of TACE surgery at a dosage of 80–160 mg (Bayer HealthCare AG, 40 mg/pill) according to the patient’s tolerance, and during weeks 1–3 of each 4-week cycle. After tumor progression, patients were treated with TACE combined with regorafenib and PD-1 antibody (sintilimab), or with continued TACE combined with regorafenib according to the wishes of the patient. Sintilimab (Innovent Biologics, Suzhou, China) was prescribed at a fixed dose of 200 mg every 3 weeks, and adverse events (AEs) were managed by reducing the pre-specified dose and delaying the next cycle. Treatment was interrupted in patients with hepatic decompensation with Child-Pugh C, clinical progression to ECOG performance status >2, or intolerable toxicity even after the dose adjustment of Sorafenib, regorafenib, or sintilimab.

Check if the same lab product or an alternative is used in the 5 most similar protocols
All patients in group A received sequential systemic therapy with molecular targeted agents after the TIPS procedure when the symptoms of portal hypertension were controlled. Patients received a daily oral dose of sorafenib (400 mg/bid, Bayer) or lenvatinib (8–12 mg/qd, Eisai Co Ltd). Patients received regorafenib (120–160 mg/qd during weeks 1–3 of each 4-week cycle, Bayer) if they were nonresponders or tolerated sorafenib or lenvatinib. The treatment strategy is shown in Fig. 3.

Treatment strategy for advanced hepatocellular carcinoma (HCC) with portal vein tumour thrombus (PVTT)–related symptomatic portal hypertension to improve survival. A transjugular intrahepatic portosystemic shunt (TIPS) is used to resolve portal hypertension complications, including variceal bleeding, refractory ascites or hydrothorax, and access to antitumour treatment opportunities (molecular targeted agents)

Evaluating Drug Combinations and siRNA Effects on Cell Growth

Check if the same lab product or an alternative is used in the 5 most similar protocols
50 μl Huh7 (2000 cell/well) and Mahlavu (1000 cell/well) cells were seeded into 96-well plates in 100 μl of medium/well. The next day, cells were treated with the drugs and CI (Cell Index) values were taken every 10 min for 4 h to get the fast drug response and then every 30 min to obtain the long-term drug response. Impedance measurements displayed as CI values reflect cell growth. The SynergyFinder Zero Interaction Potency (ZIP) model is used for the evaluation of the combined effect of PIK-75, TGX-221, and their combinations with Sorafenib (Sorafenib (Nexavar) Bayer Healthcare Pharmaceuticals, Inc., NJ USA). ZIP model defines the effect of combining two compounds by comparing the change in the dose-response curves between individual drugs and their combinations [39 (link)]. For monitoring the effects of siRNA treatment for AOX1 or AGER genes, Mahlavu and Huh7 cells were seeded onto 96-well E-Plate in triplicates. After overnight incubation, siRNA treatments were done as described previously. Cell index (CI) were recorded every 30 min for total of 96 h. Data was normalized using time-zero CI values (when siRNA treatment was performed). For statistical analysis, Two-Way ANOVA was performed using GraphPad Prism 8.

Full details on the development of a sorafenib-resistant cell line were previously published [18] (link). Briefly, HepG2 human hepatoblastoma cells (HB-8065-ATCC, Rockville, MD) were incubated with increasing doses of sorafenib (Bayer HealthCare, Leverkusen, Germany) over several months, resulting in a cell line resistant to sorafenib (HepG2S1).

HepG2 cells, Huh-7 cells and HEK-293 T cells were obtained from the Cell Bank of Chinese Academy of Sciences (Beijing, China). Cells were cultured in a dulbecco’s modified Eagle’s medium (DMEM, Gibco) with a 1:1 ratio of penicillin and streptomycin (100 U/mL) and 10% fetal bovine serum (FBS, Gibco) [17 (link)]. Sorafenib (200 mg, tablets, Bayer Inc., Germany) was used to construct the Sorafenib-resistant HepG2 cell line (namely SR-HepG2 cells) and Huh-7 cell line (namely SR-Huh-7 cells) by continuous induction.

Check if the same lab product or an alternative is used in the 5 most similar protocols
Animal procedures were performed in accordance with the UK Home Office guidelines and approved by the Ethical Review Group of Cardiff University. Tsc2+/− balb/c mice were described previously [11] (link). To test whether combination of everolimus with Sorafenib could improve antitumor efficacy, we first determined the combined maximum tolerated dose in the Tsc2+/− mice in a 2-week pilot treatment study. Tsc2+/− littermates were randomly allocated into 4 groups of 10, balanced for gender and of the same age. Animals were treated from the age of 11 months with vehicle, everolimus (10 mg/kg), Sorafenib (42 mg/kg), or everolimus (6 mg/kg) plus Sorafenib (30 mg/kg). All mice were treated five times a week via gavage for 2 months and then sacrificed for assessment of tumor burden and analysis of protein expression and phosphorylation in the kidneys. Vehicle and everolimus were supplied by Novartis Pharma AG, Basel, Switzerland. Sorafenib was supplied by Bayer Schering Pharma AG, Leverkusen, Germany.

Combinatorial Therapy for Orthotopic HCC

Check if the same lab product or an alternative is used in the 5 most similar protocols
For the established orthotopic HCC model, we confirmed tumor growth by MRI fourteen days after tissue implantation and then randomly divided the mice into different groups (Sorafenib, DC-TEX, PD-1 Ab, Sorafenib plus DC-TEX, Sorafenib plus PD-1 Ab, DC-TEX plus PD-1 Ab, Triple combination of Sorafenib, PD-1 Ab, and DC-TEX, Phosphate buffered saline, n = 6 mice/group). The tumor volume in each group was not significantly different. Sorafenib (Nexavar, Bayer Healthcare, Leverkusen, Germany) was dissolved in phosphate buffered saline (PBS) containing 1% Tween 80 and the final dose of 50 mg/kg was administered by gavage daily for three weeks. DCs were pulsed with exosomes (4×106, injected intravenously) three times, at 5-day intervals. PD-1 Ab (200 μg) was injected intraperitoneally three times at 5-day intervals (clone J43; BioXCell, West Lebanon, USA). After one week of treatment, the established orthotopic HCC model were to sacrifice and to analyze the variation. For survival analysis, the treatment was conducted as above described (n = 10 mice/group).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
