I. Introduction

A. Overview of HCP-2303

HCP-2303 is an investigational drug candidate currently navigating the initial stages of clinical development.[1] It is being developed by Hanmi Pharmaceutical Co., Ltd., a prominent South Korean pharmaceutical entity.[1] As of mid-2024, HCP-2303 has successfully completed Phase 1 clinical trials, signifying its transition from preclinical research into human testing.[1]

Available data indicate that HCP-2303 is formulated for oral administration.[1] However, critical details regarding its pharmacological profile remain undisclosed. Specifically, the mechanism of action (MoA) through which HCP-2303 exerts its effects is currently classified as "Unknown".[1] Furthermore, the specific therapeutic indication, or the disease(s) it is intended to treat, has not been specified in the available documentation.[4] This lack of detailed public information positions HCP-2303 as an early-stage asset whose full therapeutic potential and target application are yet to be defined.

B. Report Objective and Scope

The primary objective of this report is to synthesize and analyze all accessible information pertaining to the drug candidate HCP-2303, drawing exclusively from the provided research materials. The scope is strictly focused on HCP-2303, encompassing its identifiable characteristics (such as drug type and administration route), its developer (Hanmi Pharmaceutical Co., Ltd.), and the details of its completed Phase 1 clinical trial program (specifically trials HM-EMMA-101 and HM-EMMA-102). This analysis includes the context provided by the co-administered components, RLD2302 and RLD2102, which were studied alongside HCP-2303 in these trials.
