Evaluation of PK/PD, Breastmilk Transfer, and Effectiveness of Ketamine After Cesarean Delivery - Part 1
In Brief
A Phase 2 clinical trial evaluating Ketamine for Obstetric Pain and 7 related conditions. Completed, enrolled 8 participants across 2 sites.
Detailed Summary
The objective of this study is evaluate the breastmilk transfer and pharmacokinetics (Part 1) and effectiveness (Part 2) of a post-cesarean delivery intravenous ketamine bolus-and-infusion strategy, as a preventive analgesic modality to reduce pain and opioid requirements. In Part 1, physiochemical analysis of pharmacokinetic/pharmacodynamic (PK/PD) and breastmilk transfer of ketamine and its metabolites will be assessed. Additionally calculated estimations for neonatal and infant exposure will be assessed. In Part 2, PK/PD assessments will continue in a larger cohort; endpoints will also include postpartum pain, depression scores, central sensitization measures, patient-reported postpartum recovery scores, breastfeeding, and parent-infant bonding, assessed in the acute post-cesarean period and up to 12 weeks postpartum in a randomized controlled trial.

Timeline
Interventions
Subjects in the intervention arm will receive infusion dosing as noted in arm/group descriptions at the time of cord clamping. Duration of infusion will be 12 hours. Concentrations of ketamine and ketamine metabolites (nor-ketamine, NKET; and dehydro-nor-ketamine, DHNK) are measured in maternal plasma and urine as well as breastmilk. Maternal side effects, adverse events, and efficacy endpoints will be measured over the 12 hour infusion and over 15 hours after infusion discontinuation.
