qPharmetra Experience

Therapeutic Areas

qPharmetra has completed multiple projects in all these therapeutic areas. The firm has particularly deep experience with oncology, CNS and Cardiovascular drugs, resulting in models with nuanced insights on mechanisms and biology.

Oncology CNS Cardiovascular
Endocrinology Infectious Disease Pain
Gastrointestinal Men's Health Rare Disease
Hematology Metabolic Disease Respiratory
Immunology Musculoskeletal Urology

All Phases of Drug Development

qPharmetra's skills can be used at all stages of drug development from preclinical through Phase 4 to make better decisions that lead to better medicines. Establishing models early in the drug development process helps to define the assumptions around a drug, define areas where data are needed and provide a structure for integrating diverse datasets.

Regulatory Interactions

qPharmetra regularly works with its clients to produce or support regulatory documents that help to clearly express the insights from their data to justify doses, support approval, and demonstrate risks and benefits of the drug. qPharmetra has helped produce more than a dozen NDA/CTD submissions.

Industry Experience

qPharmetra consultants average over 15 years of industry experience working directly in pharma companies and consulting for them. This depth of experience allows them to understand both the technical and organizational challenges in drug development.


Most of the qPharmetra consultants are scientists or engineers with PhDs in chemical engineering, pharmaceutical science and biomathematics. This provides a range of perspectives to help solve challenging problems.


qPharmetra is comitted to sharing knowledge that will assist others in developing better medicines. To accomplish this, we publish our work whenever a client agrees, so that the drug development community and ultimately patients will benefit from new information about a drug or disease.
