Investigator Sponsored Research

Nektar Therapeutics (Nektar) has a deep and diverse portfolio of investigational medicines in different stages of clinical development. Our team of dedicated scientists, clinicians and employees are focused on bringing new medicines to patients with debilitating diseases.

As a research-based biopharmaceutical company, Nektar conducts preclinical and clinical studies of our investigational medicinal products (IMP) to evaluate them for both safety and efficacy through company sponsored and independently sponsored research such as Investigator Sponsored Research (ISR). ISR is independent research initiated, designed and conducted by qualified investigators, on Nektar IMPs and/or within Nektar’s therapeutic areas of interest. ISR is a component of our clinical research strategy.

By supporting innovative research ideas initiated by qualified investigators, we can advance the medical and scientific knowledge of Nektar’s IMPs. Research conducted through ISR can provide valuable information regarding the safety, efficacy, pharmacology, and tolerability of Nektar's IMPs. Nektar may provide support for ISR in the form of financial support and/or drug supply requests.
