Phase II & III Clinical Trials

Scale with Confidence

Our full-service approach to Phase II & III clinical trials cuts complexity, protects timelines, guarantees inspection readiness, and ensures patient-centric execution, so you can confidently move at the speed of science.

Quality, Speed, and Scale

No matter where in the world your study is or where it’s going in the next phase, our strong governance and impeccable operations help you:

Scale Phase III Easily

We deliver full-service Phase III support across clinical ops, medical monitoring, clinical data management, clinical trial biostatistics, and safety and pharmacovigilance, enabling scalable execution with structured communication and clear decision pathways.

Execute Globally

We reduce delays through early contracting, align data management and operations for timely entry and cleaning, sustain enrollment momentum, and leverage our China presence to speed site selection and activation.

Accelerate Enrollment

We accelerate enrollment and ensure inspection readiness, helping Phase II and Phase III clinical studies finish ahead of schedule and exceed targets. Through principal investigator and sub-investigator engagement, tailored site strategies, and expanded recruitment pools via optimized site selection, we enable faster, compliant study delivery.

Keep the Patients Front and Center

We map patient pathways, partner with advocacy groups, and use decentralized approaches to improve access, adherence, and diversity while minimizing logistical barriers.

Frequently Asked Questions About
Phase II and III Clinical Trials

What are the biggest operational risks when moving from Phase II to Phase III scale?

The biggest risks include rapid expansion across sites and countries, increased protocol complexity, variability in site performance, supply chain strain, and data quality challenges. Without strong governance and planning, these can lead to delays, inconsistent execution, and reduced study quality.

How do you manage multi-country site activation and keep enrollment rates stable?

We manage this through integrated start-up planning, country-specific activation sequencing, and real-time enrollment tracking. By aligning regulatory, contracting, and site readiness activities, we reduce activation delays and maintain consistent enrollment momentum across regions.

What full-service functions can you provide in Phase III (ClinOps, PV, biostats, DM, etc.)?

We provide full-service Phase III support, including clinical operations, pharmacovigilance, biostatistics, data management, medical monitoring, and regulatory support, ensuring end-to-end execution with integrated oversight and coordinated decision-making.

How do you keep complex stakeholder groups aligned on decisions and timelines?

We use structured governance, clear communication cadences, defined decision pathways, and transparent reporting. This helps sponsors, vendors, and sites remain aligned on priorities, timelines, and enables risk mitigation actions throughout the study.

How do you maintain inspection readiness throughout Phase II/III execution?

Inspection readiness is maintained through continuous quality oversight, real-time risk monitoring, standardized processes, and ongoing documentation review, ensuring audit-ready data and compliance are built into daily operations rather than addressed at study close.

What is RBQM and what does the lifecycle look like from RFP through DBL?

RBQM (Risk-Based Quality Management) is a proactive approach to identifying, assessing, and mitigating risks throughout a study. From RFP to DBL, it includes risk assessment, critical data/critical process identification, centralized monitoring, ongoing review, and continuous mitigation tracking.

How do you accelerate enrollment when eligibility is narrow, or screening failure is high?

We accelerate enrollment by optimizing site selection, engaging experienced investigators, refining pre-screening strategies, and leveraging targeted recruitment approaches. Continuous monitoring allows rapid adjustments to improve screening efficiency and retention.

How do you approach rare disease feasibility (pathway mapping, advocacy partnerships, burden reduction)?

We map patient pathways, engage advocacy groups, and assess real-world treatment journeys to understand where patients are found and how they access care. This enables feasibility strategies that reduce burden and improve recruitment potential.

What decentralized elements can reduce patient burden in rare disease trials?

Decentralized elements include telemedicine visits, home nursing, local labs, direct-to-patient drug supply, and wearable technologies. These help reduce travel burden, improve access, and increase retention in geographically dispersed populations.

Can you “rescue” a late-stage program midstream, and what does a transition look like?

Yes, we can transition late-stage programs through rapid study assessment, risk identification, governance stabilization, and operational takeover. This includes restoring enrollment, aligning vendors, reinforcing data quality, and implementing recovery plans to stabilize and complete the study.
