Anricfen for pain relief and recovery after pancreaticoduodenectomy

The Safety and Efficacy of Aniracetamfen for Postoperative Analgesia and Rehabilitation After Pancreaticoduodenectomy: A Single-center, Single-arm Clinical Study

Phase 2 Interventional The Affiliated Nanjing Drum Tower Hospital of Nanjing University Medical School · NCT07514637

This will try a short course of IV Anricfen in adults after pancreaticoduodenectomy to see if it reduces pain and speeds recovery.

What this trial studies

This Phase 2 interventional trial gives adults who undergo pancreaticoduodenectomy intravenous Anricfen at 1 μg/kg every 8 hours for three days after surgery. Pain scores, opioid consumption, and measures of recovery such as time to ambulation, return of bowel function, and length of stay will be recorded as primary and secondary outcomes. Blood and tissue samples will be collected for exploratory biomarker analyses and correlated with tumor pathology. The single-center trial is conducted at The Affiliated Nanjing Drum Tower Hospital and enrolls patients aged 18–79 with ASA I–III who can provide informed consent.

Who should consider this trial

Good fit: Adults 18–79 undergoing pancreaticoduodenectomy (including PD, PPPD, or LPD), with ASA I–III and the ability to give informed consent and tolerate postoperative IV treatment are ideal candidates.

Not a fit: Patients with severe cardiac, cerebral, hepatic, renal, or hematopoietic disease, pregnancy or lactation, chronic preoperative pain with long-term analgesic use, substance abuse, thyroid dysfunction, or known allergy to the medication are unlikely to benefit or be eligible.

Why it matters

Potential benefit: If successful, Anricfen could reduce postoperative pain, lower opioid needs, and help patients recover faster after pancreaticoduodenectomy.

How similar studies have performed: Peripheral kappa opioid receptor agonists have shown analgesic effects in preclinical work and early-phase human trials, but perioperative use after pancreaticoduodenectomy is relatively novel and not yet proven.
