Systems pharmacology of adverse event mitigation by drug combinations.

ABSTRACT: Drugs are designed for therapy, but medication-related adverse events are common, and risk/benefit analysis is critical for determining clinical use. Rosiglitazone, an efficacious antidiabetic drug, is associated with increased myocardial infarctions (MIs), thus limiting its usage. Because diabetic patients are often prescribed multiple drugs, we searched for usage of a second drug ("drug B") in the Food and Drug Administration's Adverse Event Reporting System (FAERS) that could mitigate the risk of rosiglitazone ("drug A")-associated MI. In FAERS, rosiglitazone usage is associated with increased occurrence of MI, but its combination with exenatide significantly reduces rosiglitazone-associated MI. Clinical data from the Mount Sinai Data Warehouse support the observations from FAERS. Analysis for confounding factors using logistic regression showed that they were not responsible for the observed effect. Using cell biological networks, we predicted that the mitigating effect of exenatide on rosiglitazone-associated MI could occur through clotting regulation. Data we obtained from the db/db mouse model agreed with the network prediction. To determine whether polypharmacology could generally be a basis for adverse event mitigation, we analyzed the FAERS database for other drug combinations wherein drug B reduced serious adverse events reported with drug A usage such as anaphylactic shock and suicidality. This analysis revealed 19,133 combinations that could be further studied. We conclude that this type of crowdsourced approach of using databases like FAERS can help to identify drugs that could potentially be repurposed for mitigation of serious adverse events.

Project description:IntroductionThis study aimed to gain insight from patients with refractory Mycobacterium avium complex lung disease (MAC-LD) into strategies used to manage adverse events (AEs) associated with amikacin liposome inhalation suspension (ALIS).MethodsWe conducted semi-structured interviews with US patients with refractory MAC-LD prescribed ALIS in a real-world setting. Interview transcripts were analyzed and coded to identify patterns in participants' descriptions of their ALIS treatment experiences, including AEs and their disruptiveness, and AE mitigation strategies, including participants' ratings of strategies' effectiveness. Concept saturation was also assessed.ResultsTwenty participants (mean age 48.7 years; 80% women; mean ALIS duration 5.45 months) were interviewed. At the time of the interview, 15 participants (75%) had received ALIS for > 1 month and 13 (65%) were currently receiving ALIS. Participants described 44 unique AE mitigation strategies, which can be categorized into three groups: prepare for treatment; prevent increased emergence of AEs; and persist on treatment by mitigating AEs. Common strategies (reported by ≥ 50% of participants) included use of educational materials from the patient support program, localized management of throat irritation, and symptom management to reduce fatigue. Evidence of concept saturation was observed: no new strategies were identified in the last five interviews, which suggests the sample was robust enough to identify all mitigation strategies likely to be used by the broader patient population.ConclusionsThis real-world study identified a diverse set of potential AE mitigation strategies intended to help individual patients prepare for ALIS treatment, prevent the increased emergence of certain AEs, and mitigate the impact of AEs on treatment persistence. Developing a comprehensive accounting of the types of mitigation strategies in use among patients in real-world settings can inform future investigation of the effectiveness of such strategies, and support evidence-based recommendations for treatment management.
