We apply pharmaceutical industry best practices to the unique challenges of the Cell and Gene Therapy (C&GT) field. Our team can help you with a wide range of needs, spanning from high level corporate strategy development to detailed technical implementation.

We have a dozen commonly-requested services, listed below.

During 2020, we released 20 case studies to provide concrete examples of how our expertise can support your business. In 2021 we added two additional case studies to the bank. Both of them (Remediation of CRL issues for BLA resubmission, and Embedded early for de novo support) are applicable to six of our twelve service areas. See all case studies in one place here.
