The Impact of Nonsteroidal Anti-Inflammatory Drugs, Beta Blockers, and Metformin on the Efficacy of Anti-PD-1 Therapy in Advanced Melanoma.

ABSTRACT: Anti-programmed cell death protein-1 (anti-PD-1) therapy has greatly improved outcomes of patients with melanoma; however, many fail to respond. Although preclinical studies suggest a potentially synergistic relationship with anti-PD-1 therapy and certain concurrent medications, their clinical role remains unclear. Here, we retrospectively evaluated the use of nonsteroidal anti-inflammatory drugs (NSAIDs) and other drugs in 330 patients with melanoma treated with anti-PD-1 therapy from four academic centers. In the cohort, 37% of patients used NSAIDs including aspirin (acetylsalicylic acid; ASA; 47%), cyclooxygenase (COX)-2 inhibitors (2%), and non-ASA/nonselective COX inhibitor NSAIDs (59%). The objective response rates (ORRs) were similar in patients with NSAID (43.4%) and no NSAID (41.3%) use with no significant difference in overall suvival (OS). There was a trend toward improved progression-free survival (PFS) in patients who took NSAIDs (median PFS: 8.5 vs. 5.2 months; p = .054). Most patients (71.3%) took NSAIDs once daily or as needed. Multivariate analysis did not reveal an association with NSAID use with ORR, PFS, or OS. Concurrent use of metformin or beta blockers did not affect ORR, PFS, or OS. Our study found no conclusive association of concurrent NSAID or other medication use with improved outcomes in patients with melanoma treated with anti-PD-1 therapy. Larger and more systematic analysis is required to confirm these findings.

Project description:PurposeTo evaluate the pharmacokinetics and efficacy of topically applied nonsteroidal anti-inflammatory drugs (NSAIDs) in the retinochoroidal tissues of rabbits.MethodsThe cyclooxygenase (COX) inhibitory activity of diclofenac, bromfenac, and amfenac, an active metabolite of nepafenac, were determined using human-derived COX-1 and COX-2. Each of the three NSAIDs was applied topically to rabbits, and after 0.5 to 8 hrs, the concentration of each drug in the aqueous humor and the retinochoroidal tissues was measured by liquid chromatography-tandem mass spectrometry. The pharmacokinetics of the drugs in the tissues after repeated doses as is done on patients was calculated by a simulation software. The inhibitory effect of each NSAID on the breakdown of the blood-retinal barrier was assessed by the vitreous protein concentration on concanavalin A-induced retinochoroidal inflammation in rabbits.ResultsThe half-maximal inhibitory concentration (IC50) of diclofenac, bromfenac, and amfenac was 55.5, 5.56, and 15.3 nM for human COX-1, and 30.7, 7.45, and 20.4 nM for human COX-2, respectively. The three NSAIDs were detected in the aqueous humor and the retinochoroidal tissue at all-time points. Simulated pharmacokinetics showed that the levels of the three NSAIDs were continuously higher than the IC50 of COX-2, as an index of efficacy, in the aqueous humor, whereas only the bromfenac concentration was continuously higher than the IC50 at its trough level in the retinochoroidal tissues. The intravitreous concentration of proteins was significantly reduced in rabbits that received topical bromfenac (P?=?0.026) but not the other two NSAIDs.ConclusionsTopical bromfenac can penetrate into the retinochoroidal tissues in high enough concentrations to inhibit COX-2 and exerts its inhibitory effect on the blood-retinal barrier breakdown in an experimental retinochoroidal inflammation in rabbits. Topical bromfenac may have a better therapeutic benefit than diclofenac and nepafenac for retinochoroidal inflammatory diseases.

Project description:Background & aimsNonsteroidal anti-inflammatory drugs (NSAIDs) have been suggested to protect against esophageal adenocarcinoma (EAC). This study examined the effect of NSAIDs on the risk of developing Barrett's esophagus (BE), the precursor lesion to EAC.MethodsWe conducted a case-control study among eligible patients scheduled for either elective esophagogastroduodenoscopy (EGD) or recruited from primary care clinics to undergo a study EGD. We compared 323 patients with BE (296 nondysplastic and 27 dysplastic) with 2 separate control groups: 1347 patients from the elective EGD group (endoscopy controls) and 502 patients from the primary care group (primary care controls) with no endoscopic or histopathologic BE. Use of aspirin products and 23 nonaspirin NSAIDs was ascertained from detailed, self-reported questionnaires. We calculated odds ratios (ORs) and 95% confidence intervals (CIs) using multivariable logistic regression models.ResultsThere were no significant differences in self-reported NSAID use between all BE cases and all controls (58.2% vs 54.6%; P = .33); this was seen for aspirin products (43.0% vs 37.4%; P = .08) and nonaspirin NSAIDs (7.7% vs 8.9%; P = .46). These findings persisted in the multivariable model for any NSAIDs (adjusted OR, 0.89; 95% CI, 0.75-1.28), aspirin (adjusted OR, 1.16; 95% CI, 0.90-1.51), and nonaspirin NSAIDs (adjusted OR, 0.88; 95% CI, 0.55-1.39). Use of a combination of aspirin and nonaspirin NSAIDs was reported in 7.4% of cases and 8.3% of controls, and a nonsignificant inverse association with BE was seen (adjusted OR, 0.70; 95% CI, 0.44-1.11). There was no significant association between BE and daily NSAID use (adjusted OR, 1.03; 95% CI, 0.78-1.37). Similar findings were observed for comparisons involving nondysplastic or dysplastic BE cases, and endoscopy or primary care control groups separately or combined.ConclusionsThe use of NSAIDs was not associated with a reduced risk of BE. It is likely that the protective mechanism of NSAIDs on EAC occurs subsequent to the development of BE.
