Clinical Support

As a full-service clinical research organization (CRO), Protheragen offers comprehensive clinical support services that span the entire drug development lifecycle—from first-in-human studies to post-marketing surveillance. Backed by deep expertise in the China clinical landscape and a commitment to global quality standards, we help sponsors navigate the complexities of clinical research with confidence.

Intoduction to Clinical Support

Clinical support is the operational engine of drug development—the discipline that turns a protocol into reliable, GCP-compliant evidence. It spans study start-up, site management, monitoring, recruitment, and data oversight, and it directly determines whether a trial is delivered on time, on budget, and with data that regulators will accept.

Figure 1. The Pharma Drug Development Cycle. (Harrer S, et al., 2019)

The drug development funnel: from 5,000-10,000 candidate compounds to a single approved drug, only ~10% of those entering clinical trials reach approval. The clinical phase consumes roughly half of the ~US$1.5-2B R&D cost per new drug and up to 60% of the overall timeline.

The stakes make execution quality decisive and late-stage failures are rarely pure biology: Hwang et al. attribute ~57% of Phase III failures to inadequate efficacy, often compounded by enrollment and protocol-design challenges. Yet executing trials well is genuinely hard: study start-up is a lengthy, multi-stakeholder process in which timeline slippage is common; patient recruitment and retention remain the most persistent industry-wide bottleneck; and effective monitoring now demands risk-based, analytics-driven oversight under ICH E6(R2). Building all of this in-house—across therapeutic areas, regions, and rapidly evolving decentralized models—is slow and expensive.

That is why clinical trial outsourcing has become the industry norm. Across the industry, partnering with a CRO is now standard practice, and specialized partners contribute risk-based quality management (RBQM) under ICH E6(R2) and decentralized-trial capabilities aligned with current FDA guidance, together with cross-program experience that would take years to build internally. Outsourcing clinical support lets sponsors concentrate on science and strategy, while a dedicated team de-risks the execution that approvals ultimately depend on.
