Research Overview

P11-4

P11-4 has been studied for its ability to penetrate initial carious lesions and self-assemble into a fibrillar matrix that nucleates hydroxyapatite. Human and preclinical studies support its role in non-invasive enamel repair.

Anamorelin

Trials in cachexia populations showed increased appetite and modest gains in body weight and IGF-1. Regulatory progress has varied by region, but it remains a well-studied ghrelin agonist in the GH space.
