STTEPP: Safety, Tolerability and Dose Limiting Toxicity of Lacosamide in Patients With Painful Chronic Pancreatitis
In Brief
A Phase 1 clinical trial evaluating Lacosamide for Chronic Pain and 9 related conditions. Active but no longer recruiting, targeting 21 participants across 5 sites.
Detailed Summary
The investigators propose to conduct a dose-escalation trial of an FDA-approved antiepileptic drug, lacosamide, added to opioid therapy in patients with chronic abdominal pain from chronic pancreatitis (CP). This pilot trial will test the feasibility of the study design and provide reassurance regarding the tolerability and safety of lacosamide used concomitantly with opioids in this patient population to reduce the condition known clinically as opioid-induced hyperalgesia (OIH).
Study Details
Timeline
Arms & Interventions
In the first 3-patient cohort, the dose of lacosamide given is 50mg/d BID. Enrollment to the next higher dose cohort will be initiated only if none of the 3 participants exhibits a DLT in the 21 ±3 days following completion of the 7 day drug therapy. Dose escalation will proceed according to the Bayesian optimal interval (BOIN) design at incremental increase of 100mg/day in two divided doses. The maximum daily dose of lacosamide will be 400mg/day.
Interventions
Study Visit 1: Baseline study assessments will be made and questionnaires completed in person, on day 0. Drug treatment days will then occur on days 1-7. Study Visit 2: Following completion of the 7-day drug treatment period, participants will have a face-to-face clinic visit on day 8 (with a 3 day grace period), where similar assessments and questionnaires will again be completed. Participants will return all unused drug at this visit, for disposal and to monitor compliance. A follow-up phone visit will occur on day 21 (with a 3 day window) to assess for adverse events and medication changes
