Recurrence of Retinopathy of Prematurity Following Anti-vascular Endothelial Growth Factor (Anti-VEGF) Therapy: A Systematic Review and Meta-Analysis

Review

Author: Dablouk, Mohammed ; Chhabra, Amit ; Masoud, Ahmed T

Retinopathy of prematurity (ROP) is a neovascular disorder which affects premature infants and can lead to childhood blindness. Treatment includes laser photocoagulation and intravitreal anti-vascular endothelial growth factor (anti-VEGF) injections, both effective options. However, laser photocoagulation can lead to refractive errors, while anti-VEGF therapy can result in disease recurrence. Our systematic review aimed to evaluate the recurrence rates of ROP following treatment with anti-VEGF agents compared to other anti-VEGF agents and laser photocoagulation. We also aimed to measure the retreatment intervals and assess successful retreatment rates to identify the most effective treatment modality. Our review adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and included both randomized controlled trials (RCTs) and non-randomized comparative studies (NCS). A thorough search of MEDLINE, EMBASE, Web of Science, and Cochrane Central Register of Controlled Trials (CENTRAL) databases was performed. Studies were assessed using the Cochrane Risk of Bias (RoB2) tool and the Newcastle-Ottawa Scale (NOS). Random-effects and fixed-effects models were used to measure pooled estimates. The outcomes were reported as risk ratios (RR) and standardized mean differences (SMD). A total of 21 studies (six RCTs and 15 NCS) with 6,152 eyes were included. Overall, anti-VEGF agents showed a higher risk of recurrence compared to laser photocoagulation (RR=2.14, 95% CI: 1.06-4.33, p=0.03). Conbercept demonstrated a significantly lower risk of recurrence than laser photocoagulation and ranibizumab (RR=0.47, 95% CI: 0.39-0.58, p<0.00001), while aflibercept showed a higher recurrence risk compared to bevacizumab (RR=12.61, 95% CI: 6.43-24.73, p<0.00001). Bevacizumab was associated with a longer retreatment interval than laser photocoagulation (SMD=0.89, 95% CI: 0.61-1.17, p<0.00001). No significant differences in retreatment success rates between bevacizumab and laser photocoagulation were observed. Anti-VEGF therapy is effective in the treatment of ROP; however, it is associated with a higher risk of recurrence compared to laser photocoagulation. Conbercept shows greater efficacy in reducing recurrence risk and prolonging the retreatment interval compared to ranibizumab. Aflibercept demonstrated inconsistent outcomes. No significant difference in recurrence rates was observed between bevacizumab and ranibizumab. Recurrences occurred significantly later when anti-VEGF therapy was used compared to laser photocoagulation. Successful retreatment rates between bevacizumab and laser photocoagulation were similar.

BACKGROUND:

Patients with recurrent or metastatic advanced colorectal cancer (mCRC) often face the clinical dilemma as this unresectable disease is continuously progressing and endangering the patients' lives. In the current study, we explored the clinical feasibility of KH903 in combination with FOLFIRI chemotherapy as a new clinical indication for mCRC.

METHODS:

Patients (N = 122) were randomized 1:1 to 4mg/kg q1w KH903 or 5mg/kg q2w KH903, and both groups of patients were treated with the fixed regimen of FOLFIRI (every 2 weeks) along with the KH903 therapy. The primary endpoint was progression-free survival (PFS), and the secondary endpoints were Overall Survival (OS), objective response rate (ORR), and disease control rate (DCR).

RESULTS:

As of December 30, 2020, median (m)PFS was 5.68 months (95% CI, 4.67-7.13) with 4mg/kg q1w versus 5.19 months (95% CI, 4.04, 5.78) with 5mg/kg q2w (HR, 0.76; 95% CI, 0.50-1.16),and mOS was 13.14 months (95% CI, 10.61-19.52) versus 16.03 months (95% CI, 10.28- NE), respectively (HR, 1.11; 95% CI, 0.65-1.89), The ORR was 15.9% and 11.9% for both groups, respectively, and The DCR for both groups was 85.7% and 83.1%, respectively. Grade 3 or higher treatment-related adverse event rates for both groups were 68.3% vs.52.5%, respectively.

CONCLUSIONS:

KH903 in combination with FORFIRI in second-line treatment of patients with mCRC showed prolonged mPFS and mOS, comparing to the similar agents (Avastin®, ZALTRAP®, Cyramza®) and no new safety signals were observed.

Vascular endothelial growth factor/connective tissue growth factor and proteomic analysis of aqueous humor after intravitreal conbercept for proliferative diabetes retinopathy

Article

Author: Rong, Ao ; Rong, Ao ; Lyu, Xiao ; Cui, Hong-Ping ; Cui, Hong-Ping ; Li, Hou-Shuo ; Xu, Wei ; Xu, Wei ; Bi, Yan-Long ; Bi, Yan-Long

AIM: To investigate the role of connective tissue growth factor (CTGF) and vascular endothelial growth factor (VEGF) in the protein profile of the aqueous humor in patients with proliferative diabetic retinopathy (PDR) following intravitreal injection of conbercept. METHODS: This study included 72 PDR patients and 8 cataract patients as controls. PDR patients were divided into 3 groups according to the intervals of 3, 5, and 7d between intravitreal conbercept (IVC, 0.5 mg/0.05 mL) injection and pars plana vitrectomy (PPV) performed. Aqueous humor samples were collected before and after IVC and PPV for VEGF and CTGF levels detected with enzyme-linked immunosorbent assay (ELISA). The differential proteomics of 10 patients who underwent PPV surgery 5d after IVC and 8 normal controls was studied, Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis were performed on the data, and the protein interaction network of 23 differential proteins was studied. RESULTS: Post-IVC, VEGF levels decreased and CTGF levels increased significantly in aqueous humor, with the CTGF/VEGF ratio rising significantly at all intervals. Liquid chromatography tandem mass spectrometry (LC-MS/MS) identified differentially expressed proteins between pre- and post-IVC samples. GO and KEGG analyses revealed involvement in immune response, stress response, complement and coagulation cascades, ferroptosis, and PPAR signaling pathways. PPI analysis highlighted key proteins like APOA1, C3, and transferrin (TF). ELISA assay confirmed the differential expression of proteins such as HBA1, SERPINA1, COL1A1, and ACTB, with significant changes in the IVC groups. CONCLUSION: The study demonstrates that IVC effectively reduces VEGF levels while increasing CTGF levels, thereby modifying the CTGF/VEGF ratio, and IVC significantly alters the protein profile in the aqueous humor of patients with PDR. Proteomic analysis reveals that these changes are associated with critical biological pathways and protein interactions involved in immune response, stress response, and cellular metabolism.

Gastric Cancer Overview Stomach cancer is cancer that begins within the stomach or on the stomach wall. It is also known as gastric cancer. Stomach cancer is more common in the elderly. People aged 75 and above account for approximately 50 out of every 100 cases (around 50%). It affects men more than women. The exact gastric cancer causes are not known. Stomach cancer is linked to Helicobacter pylori, a bacteria that lives in the stomach. The most common gastric cancer symptoms are difficulty swallowing (dysphagia), weight loss, persistent indigestion (dyspepsia), feeling full after eating small amounts, feeling or being sick, and fatigue due to low red blood cell count (anaemia). Several tests, such as ultrasound, imaging tests, blood tests, and others, are used for gastric cancer diagnosis. Gastric cancer patients can receive a variety of treatments. Standard gastric cancer treatment consists of seven types: surgery, endoscopic mucosal resection, chemotherapy, radiation therapy, chemoradiation, targeted therapy, and immunotherapy.

Roche touts less onerous schedule for its in-the-eye injection faricimab, hoping to sweeten the sales pitch over Eylea

Regeneron has made its name on the back of wet AMD drug Eylea, but the blockbuster’s dosing schedule of into-the-eye shots every eight weeks is no cakewalk for patients. Roche, looking to take the fight to Eylea with faricimab, thinks it has a lighter schedule that could help sway physicians. Roughly half of patients across four Phase III trials eligible for extended dosing of faricimab were able to be treated every four months after one year, subsidiary Genentech announced Friday, and nearly 75% could take the experimental drug every three months. Roche has already prepped a hefty data package for its hopeful Eylea competitor, releasing trickling data from four Phase III trials over the last few months in diabetic macular edema and wet AMD. “These positive results show the potential for faricimab as the first new type of medicine in 15 years for people with neovascular age-related macular degeneration and in close to a decade in diabetic macular edema,” Roche CMO Levi Garraway said in a statement. Two of the trials evaluated faricimab in DME and two studied it in wet AMD. Extending the dosage periods and measuring the proportion of people able to do so was a key secondary endpoint, Roche said. The DME studies showed 52.8% and 51% of patients, respectively, achieved four-month dosing at one year. On top of that, another 21% and 20.1% in each study were able to be dosed every three months. Then, in wet AMD, the studies registered a respective 45.7% and 44.9% of patients who received four-month dosing regimens. Another 34% and 32.9% of individuals managed three months between doses. Each of the four studies saw about 300 patients randomized into the drug arms, and Friday’s data come from a total of 1,225 individuals across all four groups. Roche is expected to present full data from all four trials this weekend, where analysts expect significant warning signs for Eylea’s dominance. The faricimab program has already demonstrated non-inferiority in both diseases, and coupled with the extended time between doses, the candidate has emerged as the “top competitive threat” to the Regeneron franchise, Cowen’s Yaron Werber wrote earlier this week. Faricimab is the first bispecific antibody for AMD, targeting two pathways — angiopoietin-2 and vascular endothelial growth factor-A. The treatment, like Eylea, is injected directly into the eye and designed to prevent inflammation and blood vessels from leaking. Longer time between doses is central to Roche’s pitch, given the inherent discomfort in receiving any sort of eye injectable. Roche hasn’t specified when it’s submitting the data to regulators, but Werber predicts it could make it to the market sometime in 2022. Faricimab isn’t the only potential Eylea competitor, however, with Chengdu Kanghong’s Conbercept and Kodiak’s KSI-301 also making moves. But it’s still too early to say how much impact that program could have, he wrote.
