Workflow
The service process is a multi-stage, high-fidelity journey designed to minimize risk and maximize clinical output.
- Strategic Development Planning
We begin with a comprehensive gap analysis of your preclinical data to establish a regulatory roadmap. This stage involves defining primary endpoints, including the percentage of body weight reduction at 52 weeks, and secondary metabolic markers such as HbA1c and lipid profiles.
- Protocol Design and Optimization
Leveraging our expertise in metabolic science, we draft robust clinical protocols. This includes the integration of standard-of-care lifestyle interventions to ensure the trial environment mirrors real-world clinical practice, a key requirement for modern regulatory approval.
- Scientific Medical Writing and Submission
Our team of expert medical writers develops the IB and IND application. We focus on a cohesive narrative that links the mechanism of action, such as GLP-1/GIP receptor agonism, to the anticipated clinical outcomes.
- Clinical Execution and Standardized Monitoring
During the trial, we provide medical monitoring to manage dose-escalation phases, which are critical for maintaining patient tolerability in anti-obesity studies. Our standardized monitoring ensures all SAEs are captured and reported in real-time.
- Data Synthesis and CSR Finalization
Following the database lock, we produce an ICH-compliant CSR. This document translates raw data into a persuasive scientific argument, ready for a new drug application (NDA) or marketing authorization application (MAA) submission.
Applications
- Pharmaceutical Companies: Focused on developing potent GLP-1, GIP, and glucagon receptor mono-, dual-, or tri-agonists. We assist in characterizing dose-response relationships and managing the titration complexities inherent in large-scale injectable and oral peptide programs to ensure high patient compliance and robust efficacy data.
- Biotech Startups: Advancing first-in-class small molecules for metabolic health, including mitochondrial uncouplers or lipase inhibitors. We provide the high-level scientific support needed to translate novel mechanisms of action into cohesive regulatory narratives that highlight potential advantages over existing standard-of-care therapies.

Publication Data
Title: Incomplete data and potential risks of drugs in people with obesity
Journal: Current Obesity Reports, 2023
DOI: https://doi.org/10.1007/s13679-023-00532-1
Summary: This pivotal review identifies a critical gap in the pharmacological landscape: the historical exclusion or underrepresentation of individuals with obesity in clinical drug trials across various therapeutic areas beyond weight loss. The authors demonstrate that obesity induces significant physiological alterations, such as changes in body composition, organ function, and metabolic pathways, which profoundly affect drug disposition and pharmacodynamic action. By failing to account for these systemic changes, traditional drug development often overlooks the specific safety and efficacy needs of a large segment of the global population, creating a regulatory blind spot that can jeopardize patient outcomes and therapeutic precision.
Furthermore, the review emphasizes that a one-size-fits-all dosing approach is often inadequate for this clinically complex demographic, potentially leading to suboptimal efficacy or increased toxicity. The authors advocate for a shift toward evidence-based, inclusive trial designs that incorporate robust PK/PD data specifically from individuals with obesity. This scientific perspective underscores the importance of data generalizability and highlights the necessity for future drug development programs to integrate sophisticated modeling and inclusive protocols to ensure that final labeling reflects accurate and safe dosing guidance for the global population.
