Association between ramucirumab-related hypertension and response to treatment in patients with metastatic gastric cancer.

ABSTRACT: Hypertension (HTN) is frequently associated with the use of angiogenesis inhibitors targeting the vascular endothelial growth factor pathway, such as ramucirumab. The aim of this study was to retrospectively evaluate if occurrence of HTN is correlated with response to second line treatment with ramucirumab+paclitaxel for metastatic gastric cancer.Treatment consisted of ramucirumab 8 mg/kg intravenously (iv) on days 1 and 15, plus paclitaxel 80 mg/m2 iv on days 1, 8, and 15 of a 28-day cycle. Patients received study treatment until disease progression, unacceptable toxicity, or withdrawal of consent.Thirty-four patients were retrospectively evaluated. Among these, 6 (17.6%) developed grade 3 ramucirumab-induced HTN. These patients had a better outcome than those with lesser grades events, with a progression-free survival (PFS) of 7.8 months (95% CI 4.4-not reached) versus 4.2 months (95% CI 3.1-5.2) (p=0.001). overall survival (OS) was 11.9 months (95% CI 9.3-not reached) in the grade 3 HTN group, versus 7.2 months (95% CI 5.9-10.1).Despite the small number of patients and the retrospective nature of the data, our analysis showed that occurrence of ramucirumab-related HTN, in particular G3 HTN, predicts response to treatment with ramucirumab+paclitaxel in patients with metastatic gastric cancer.

Project description:Background Nanoparticle albumin-bound paclitaxel (nab-PTX) has shown non-inferiority to paclitaxel (PTX) as second-line therapy for advanced gastric cancer (AGC) with fewer infusion-related reactions. The efficacy and safety of nab-PTX plus ramucirumab (RAM) was reported in a phase II trial; however, there is no randomized trial comparing this regimen with PTX plus RAM in patients with AGC. This retrospective study aimed to investigate the efficacy and safety of nab-PTX plus RAM versus PTX plus RAM in patients with AGC. Methods This study included patients with AGC who received nab-PTX plus RAM from September 2017 to January 2019 or PTX plus RAM from June 2015 to August 2017 as second-line chemotherapy in our hospital. Results A total of 113 and 138 patients who received nab-PTX plus RAM and PTX plus RAM, respectively, were analyzed. Median progression-free survival (PFS) was 3.9?months (95% confidence interval [CI]: 3.4–4.3) in the nab-PTX plus RAM group and 3.9?months (95% CI: 3.1–4.7) in the PTX plus RAM group (hazard ratio [HR]: 1.08; 95% CI: 0.83–1.40; P?=?0.573). Median overall survival (OS) was 10.9?months (95% CI: 9.3–12.7) in the nab-PTX plus RAM group and 10.3?months (95% CI: 8.5–12.0) in the PTX plus RAM group (hazard ratio: 0.82; 95% CI: 0.61–1.10; P?=?0.188). In patients with moderate/massive ascites, favorable outcomes for progression-free survival were observed in the nab-PTX plus RAM group compared with the PTX plus RAM group. Although anemia and fatigue (any grade) were more frequent in the nab-PTX plus RAM group, discontinuation of study treatment was not increased in the nab-PTX plus RAM group. There was no occurrence of hypersensitivity reaction in the nab-PTX plus RAM group, while two patients (1.4%) experienced grade 3 hypersensitivity reactions in the PTX plus RAM group. Conclusions The combination of nab-PTX plus RAM showed a similar efficacy and safety profile to PTX plus RAM as second-line treatment for patients with AGC.

Project description:PurposeSecond-line treatment with ramucirumab-paclitaxel has demonstrated statistically significant and clinically meaningful survival outcomes compared to paclitaxel-alone in patients with advanced gastric cancer (HR=0.807, 95% CI 0.678-0.962; P=0.017). Post hoc, exploratory analyses of RAINBOW patient data were performed to examine whether ascites impacted the efficacy and safety of ramucirumab-paclitaxel.Patients and methodsPatients were placed in with- or without-ascites subgroups based on baseline information collected on case report forms. The Kaplan-Meier method was used to estimate median progression-free survival (PFS) and overall survival (OS) of the ascites subgroups. HR and 95% CI were calculated using the Cox proportional hazards model. Survival distributions within the two arms in each ascites subgroup were compared using the log-rank test.ResultsThere were 36% of RAINBOW trial patients (237/665) that had ascites at baseline (with-ascites subgroup); 64% of patients (428/665) had no baseline ascites (without-ascites subgroup). Most baseline characteristics were balanced. The with-ascites subgroup had a higher percentage of patients with peritoneal metastases (91% vs 23%) as expected. Overall survival for the with-ascites subgroup was worse than for the without-ascites subgroup (median OS for placebo-treated patients: 5.2 vs 8.5 months, respectively). However, OS treatment effects did not seem to differ significantly among patients with ascites (OS stratified HR=0.864, 95% CI=0.644-1.161; P=0.3362) vs those without ascites (OS stratified HR=0.745, 95% CI=0.593-0.936; P=0.0115). Similar results were observed for PFS. Ramucirumab treatment was associated with a greater incidence of all-grade vomiting for the with-ascites subgroup vs the without-ascites subgroup (ramucirumab arm: 39.2% vs 18.8%; placebo arm: 23.3% vs 19.5%, respectively). The incidence of adverse events of special interest was not elevated among the ramucirumab-treated ascites subgroup over the without-ascites subgroup.ConclusionThe benefit/risk profile of ramucirumab-paclitaxel remains favorable in patients with ascites and is consistent with the findings of the RAINBOW trial.

Project description:ImportanceWhile the incidence of early-onset metastatic colorectal cancer (mCRC) has been increasing, studies on the age-related disparity in this group of patients are limited.ObjectiveTo evaluate the association of age with treatment-related adverse events and survival in patients with mCRC and explore the potential underlying factors.Design, setting, and participantsThis cohort study included 1959 individuals. Individual data on 1223 patients with mCRC who received first-line fluorouracil and oxaliplatin therapy in 3 clinical trials, and clinical and genomic data of 736 patients with mCRC from Moffitt Cancer Center were used to assess genomic alterations and serve as an external validation cohort. All statistical analyses were conducted from October 1, 2021, through November 12, 2022.ExposuresMetastatic colorectal cancer.Main outcomes and measuresSurvival outcomes and treatment-related adverse events were compared among patients in 3 age groups: younger than 50 (early onset), 50 to 65, and older than 65 years.ResultsIn the total population of 1959 individuals, 1145 (58.4%) were men. Among 1223 patients from previous clinical trials, 179 (14.6%) in the younger than 50 years group, 582 (47.6%) in the 50 to 65 years group, and 462 (37.8%) in the older than 65 years group had similar baseline characteristics except for sex and race. The younger than 50 years group had significantly shorter progression-free survival (PFS) (hazard ratio [HR], 1.46; 95% CI, 1.22-1.76; P < .001) and overall survival (OS) (HR, 1.48; 95% CI, 1.19-1.84; P < .001) compared with the 50 to 65 years group after adjustment for sex, race, and performance status. Significantly shorter OS in the younger than 50 years group was confirmed in the Moffitt cohort. The younger than 50 years group had a significantly higher incidence of nausea and vomiting (69.3% vs 57.6% [50-65 years] vs 60.4% [>65 years]; P = .02), severe abdominal pain (8.4% vs 3.4% vs 3.5%; P = .02), severe anemia (6.1% vs 1.0% vs 1.5%; P < .001), and severe rash (2.8% vs 1.2% vs 0.4% P = .047). The younger than 50 years group also had earlier onset of nausea and vomiting (1.0 vs 2.1 vs 2.6 weeks; P = .01), mucositis (3.6 vs 5.1 vs 5.7 weeks; P = .05), and neutropenia (8.0 vs 9.4 vs 8.4 weeks; P = .04), and shorter duration of mucositis (0.6 vs 0.9 vs 1.0 weeks; P = .006). In the younger than 50 years group, severe abdominal pain and severe liver toxic effects were associated with shorter survival. The Moffitt genomic data showed that the younger than 50 years group had a higher prevalence of CTNNB1 mutation (6.6% vs 3.1% vs 2.3%; P = .047), ERBB2 amplification (5.1% vs 0.6% vs 2.3%; P = .005), and CREBBP mutation (3.1% vs 0.9% vs 0.5%; P = .05), but lower prevalence of BRAF mutation (7.7% vs 8.5% vs 16.7%; P = .002).Conclusions and relevanceIn this cohort study of 1959 patients, those with early-onset mCRC showed worse survival outcomes and unique adverse event patterns, which could be partially attributed to distinct genomic profiles. These findings may inform individualized management approaches in patients with early-onset mCRC.
