About us

HCC was founded by Sven Tops and Ilse Cassiman with the aim of creating the most cost-effective international market access consultancy company. Given the high complexity of market access processes on an international scale, HCC collaborates with experienced professionals across markets and scientific disciplines.

Founding Managing Partner Sven Tops holds master's degrees in physical education and health economics. He worked for eight years in a pharmaceutical sales and marketing function followed by 12 years as Market Access Manager and then Director with a team of four direct reports. In this role, he carried out international payer research and value messaging and successfully submitted pricing and reimbursement files and delivered contract negotiations in Belgium and Luxembourg.

Sven has held numerous relevant memberships.  He was a member of the Belgian Pharma.be Market Access Taskforce, and the ISPOR Leadership Group on HTA and Good Research Practices for reimbursement decisions.  He represented Sanofi in Belgian working groups to establish Belgian guidelines for pharmacoeconomic research, and lead the Sanofi Payer Stakeholder Management Working Group which addressed how to approach payers and their influencers in order to improve market access.

Sven has significant market access experience across a wide range of therapeutic areas including diabetes, cardiology, neurology, orphan disease, oncology, dermatology and immunology. He has in depth knowledge in the fields of:

  • Market research
  • Medical writing
  • Health economics
  • Budget impact analysis
  • Innovative contracting
  • Complex stakeholder management (academic and institutional e.g. healthcare insurers and governments)
  • Payer research and mock negotiations
  • Delphi panel research
  • Cost research

Additionally, Sven’s extensive experience has led to an understanding of the dynamics of management and business needs which is beneficial to complex internal strategic discussions.

Senior partner Ilse Cassiman holds a master's degree in hospital sciences and is well trained as a medical writer and systematic literature reviewer.
