NCT05572190

Brief Summary

The goal of this Phase 1 clinical study is to evaluate the safety, tolerability, and pharmacokinetics (PK) of O2P (Oral Overdose Protected) hydrocodone prodrugs (ETR028 and ETR029) relative to hydrocodone bitartrate hemipentahydrate (HCBT) comparator following single oral doses in healthy adult subjects under fasted and fed conditions with naltrexone blockade

Outcome Measures

Primary Outcomes (3)

  • Pharmacokinetic (PK) profile

    Plasma concentration-time profile (ng/ml) of ETR028, ETR029, \[ETR028 + ETR029\] blend, O2P hydrocodone-derived 3 major metabolites (e.g., 3-hydroxy-arylguanadine \[3-HAG\], 4-hydroxy-arylguanadine \[4-HAG\], and ETR106), and hydrocodone

    Time Zero (just prior to dose) to 48 hours post dose Timepoints: pre-dose and at 0.5,1, 1.5, 2, 2.5, 3, 4, 6, 8, 10, 12, 24, 36, and 48 hours post-dose.

  • Subjects reporting at least one Adverse Event (AE)

    An AE can be any unfavorable and/or unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of the investigational medicinal product, whether or not related to the investigational medicinal product.

    From the time a subject is dosed until 8 day post-dose Follow-Up Visit

  • Subjects reporting at least one Serious Adverse Event (SAE)

    A Serious Adverse Event is an AE that results in any of the following outcomes; Death, Life-threatening, inpatient hospitalization or causes prolongation of existing hospitalization, persistent or significant disability/incapacity, congenital anomaly/birth defect, important medical event (i.e., based upon appropriate medical judgment, they may jeopardize the subject and may require medical or surgical intervention to prevent 1 of the outcomes listed above)

    From the time a subject is dosed up to 30 days post-dose
