Clinical Research Services
At QPS, a global full-service Contract Research Organization (CRO), clinical research services encompass comprehensive support for the development and approval of new therapies across all phases of clinical development. These services typically include study design, site selection, regulatory affairs, patient recruitment, clinical trial management, data collection and analysis, pharmacovigilance, and biostatistics, supported by robust laboratory services, such as preclinical studies (pharmacology and DMPK) and bioanalysis. With offices in USA, Europe, Asia, Australia, and India, and a site network of over 700 locations, QPS leverages local expertise and regulatory knowledge to streamline trial execution across multiple regions, ensuring compliance with international standards. By integrating cutting-edge technology and therapeutic expertise, QPS helps pharmaceutical, biotechnology, and medical device companies accelerate timelines, maintain excellence and bring safe, effective treatments to market more efficiently.
All services are conducted in accordance with ICH-GCP standards (International Conference on Harmonization-Good Clinical Practice) and local regulatory requirements to ensure consistent data integrity and patient safety.

Whether launching an early-phase trial or evaluating post-market safety, we tailor services to each protocol for reliable, reproducible outcomes.
Clinical Trial Types and Capabilities
QPS provides full-service clinical trial support across a wide range of study designs and scientific needs. Our capabilities include:
- Phase I - IV Trials: Comprehensive trial management for every clinical development stage.
- First-in-Human Trials: Safely transitioning innovative therapies from preclinical to clinical stages.
- Pharmacokinetics & Pharmacodynamics: Studying how drugs interact with the body and their mechanisms of action.
- Bioavailability & Bioequivalence: Measuring absorption and efficacy of pharmaceutical formulations.
- Drug-Drug Interaction (DDI) Studies: Assessing safety and efficacy when drugs are combined.
- Food Effect Studies: Evaluating how food impacts drug pharmacokinetics.
- Single & Multiple Dose Escalation (SAD/MAD): Determining optimal dosage levels through rigorous study protocols.
- Efficacy Endpoints: Precise evaluation to ensure trial outcomes meet regulatory and scientific benchmarks.
- Bridging Studies: Ensuring clinical data applicability across diverse populations.
- Basket Studies: Early stage oncology clinical trials conducted to determine how a drug works in patients who have different types of cancer that all have the same mutation or biomarker.
- Post-Marketing Studies: Supporting the safety evaluation of drugs after they reach the market.
- Real World Data (RWD) & Real World Evidence (RWE): RWD studies gather the raw data collected from real-world sources (patients or databases), while RWE studies deliver the evidence generated from analyzing and interpreting that data.
