Opt-X-pense Ltd. is a privately owned company established in Hungary. Since its roll-out in 2014, the company has been operating with the aim to support clinical trial sponsors and clinical trial participants by providing reasonable solutions to patient reimbursement and compensation needs. The founders and owners spent sevaral years in clinical research management which enabled them to design, implement and continuously develop these innovative solutions.


Our mission is to provide clinical trial reimbursement services utilizing simple and effective processes that reduce workload and costs for all parties involved.

Reimbursement of clinical trial subjects is a complex task sometimes requiring considerable extra work and cost burdens for sponsoring companies, the clinical trial sites and even for the subjects. Additional care must be exercised to ensure all other data privacy, law, ethical and taxation concerns are addressed. We have the optimal solutions for reimbursement that deals with all of these problems!

Our Services

Opt-X-pense's reimbursement services are unique, transparent and highly effective in assisting companies to implement a successful reimbursement management system.
Our unique reimbursement program helps the subjects to understand how they will get paid for their applicable costs related to their participation in a clinical trial. We also understand the need for confidentiality of sensitive data. We anonymize all subject data to ID codes and study numbers so that any reports you receive are completely in line with EMA, FDA, and other competent authorities/ethics committees' requirements.

Based on the steady growth of our operations in Hungary, we have developed the next generation of reimbursement service supported by a Pre-Paid Card system. The new system allows our clients to utilize our system in several countries at the highest data privacy standards and significantly reducing their vendor management related costs by using a single vendor for multiple countries.

Subject compensation
and reimbursement options


Subjects participating in clinical trials authorize us to handle their confidential data for the purpose outlined in the applicable agreement.

All data is stored on a secure server utilizing current information security best practices.

We ensure that all visit and payment confirmation is coded in our system so that subject's personal data are kept strictly confidential and cannot be revealed by the sponsoring companies. In the event the bills are sent to us we anonymize the details to ensure that the reports sponsoring companies can see will meet the standards needed for sponsoring companies and regulatory authorities such as the EMA, FDA or other authorities and ethics committees. Subject information and travel arrangements are totally confidential with reports only showing ID codes and study numbers.
