Endeavor to Stop Nausea/Vomiting Associated With Pregnancy (E-SNAP) — ESNAP  

Pregnancy Clinical Trial

Official title:
Endeavor to Stop Nausea/Vomiting Associated With Pregnancy (E-SNAP)

Clinical Trial Summary

The primary objective of this proposal is to conduct an early Phase 2 clinical trial to determine the acceptability, dosing, tolerability and safety of mirtazapine for severe nausea and vomiting of pregnancy (sNVP) that is not adequately responsive to current standard treatments. This plan mirrors clinical practice since commonly prescribed antiemetic/ antinauseant drugs will be tested for efficacy before treating with mirtazapine.

Clinical Trial Description

Translational Research in Maternal and Pediatric Pharmacology and Therapeutics (PAR-20-299) supports research to "enhance the usage of existing drugs or drug repurposing for safer and more effective treatment for pregnant women" for "the early and conceptual stages of these projects. The primary objective of this proposal is to conduct an early Phase 2 clinical trial to determine the acceptability, dosing, tolerability and safety of mirtazapine for severe nausea and vomiting of pregnancy (sNVP) that is not adequately responsive to current standard treatments. This plan mirrors clinical practice since commonly prescribed antiemetic/ antinauseant drugs will be tested for efficacy before treating with mirtazapine. Mirtazapine is a promising drug to repurpose for sNVP. It has potent anti-emetic properties and is available as an oral disintegrating formulation. It is used off-label to treat NV during cancer chemotherapy, prevent post-surgical nausea and vomiting and for gastroparesis. It is marketed as the serotonin-norepinephrine reuptake inhibitor antidepressant Remeron®. Mirtazapine has multiple receptor effects beyond those involved in reducing depressive symptoms. In cancer and chemotherapy patients, it produces rapid resolution of nausea and vomiting by blocking physiologic inputs that coordinate emesis. It is hypothesized that repurposing mirtazapine for obstetric use overcomes the challenges of traditional pathways to develop new agents because its pharmacokinetics, safety and dosing have been established for general populations of patients and exposure data are available because it is prescribed to pregnant persons with depression. ;
