Late phases studies overview
Since 2015 we have been organizing and conducting scientific, preclinical, and clinical studies of pharmaceuticals and medical devices, as well as implementing new diagnostic and treatment methods in compliance with international ethical and regulatory standards.

To date, we have conducted over 130 clinical trials across 27 therapeutic areas in Eastern Europe and Asia, spanning all phases.

One of our key focus areas is vaccine clinical trials. Our experience includes large-scale studies of vaccines for COVID-19, pneumococcal and meningococcal infections, influenza, MERS, tuberculosis, SARS, and other diseases, involving thousands of volunteers. Our specially developed Vaccine Fast Track approach utilizes advanced algorithms and data-driven forecasting to accelerate research without compromising quality.
Early phases studies overview
Since 2015, our company has specialized in organizing and conducting early-phase clinical trials, including:
  • Phase I studies, including first-in-human (FIH) trials;
  • Bioequivalence (BE) studies;
  • Early-phase studies of small molecules and biologics.
Our key capabilities:
  • Conducting cohort studies with single and multiple ascending doses;
  • Experience with various study designs, including the "3+3" dose-escalation scheme;
  • Deep expertise in pharmacokinetics (PK) and pharmacodynamics (PD).
Over the years, Accellena R&D has investigated comparative pharmacokinetics of various dosage forms, including sprays, and has experience with studies featuring pharmacodynamic endpoints.

Data Management and Biostatistics
Data management (DM) services are being provided by Accellena R&D from 2015. From 2017 we have it as in-house department.

We provide services for database and EDC development, data collection and routine data management, as well as data processing in accordance with Good Clinical Data Management Practice.

Since 2017 we have collected and processed data for more than 120 clinical trials of various phases and types, in which data from more than 22,000 study subjects were processed.


Real World Data (RWD) / Real World Evidence (RWE)
Since its establishment in 2015, Accellena R&D has been conducting real-world evidence (RWE) studies to evaluate the effectiveness and safety of various therapeutic interventions in real-world clinical settings.

Today, leading regulatory agencies are actively developing and refining guidelines for such studies. At Accellena R&D, we employ cutting-edge technologies and methodologies to ensure the reliability and credibility of our research data, including:
  • Advanced data collection and processing systems:
  • Centralized statistical monitoring:
  • Comprehensive risk assessment and mitigation approaches.

These solutions enable us to:
  • Generate high-quality real-world data (RWD) efficiently
  • Conduct timely and relevant clinical studies
  • Build a robust evidence base grounded in real-world clinical practice (RWE)

By combining regulatory expertise with innovative tools, we help bridge the gap between clinical research and everyday patient care.
    Our devotion to evidence-based medicine is fostered by our daring dream of healthy humanity expanding to space.

      Founder of Accellena R&d
      "We are passionate about creating and implementing new time and cost-effective tools and methodologies, such as comparative PK/PD studies that take a wider range of factors altering metabolism into consideration, or applying new managerial methodologies in the way we organize our research teams".
    • Artem Sergeenko
      Project Management
      "The key is integral thinking, in which each team member is aware of their unique function and area of responsibility, and at the same time, is able to perceive the health of the project in its entirety. We are strong in people and teams, this is the secret of successfully passing critical milestones of a trial and faster drug development. Isn't this what humanity needs?"
    • Maria Belavina
      QUALITY ASSURANCE
      "Quality assurance is not a matter of trust anymore, it is rather a technological challenge that is being solved today with the use of superior IT tools tailored individually for each project in compliance with GCP. And last but not the least, her majesty "discipline" - the holy grail of evidence-based medicine - rules everything."
    • Alexandra Eller
      Data Management
      "In clinical research, data management (DM) is a powerhouse, driving the accuracy and success of studies. By embracing advanced and efficient DM techniques, researchers can streamline data collection, analysis, and standardisation, especially critical in multicenter and international studies. This proactive approach not only speeds up the drug approval process but significantly boosts the odds of research success."
