Double Bond aims at adaptive design for SI-053 Phase I

Double Bond Pharmaceutical (DBP) has signed a service contract with Cytel Inc, a leading provider of clinical research services and software, to develop an adaptive model-based study design for upcoming Phase I clinical trial for SI-053.

“In our planned Phase I dose-escalation study we aim at using an adaptive model-based design to help identify the maximum tolerated dose (MTD) of SI-053, – says Dr Breezy Lindqvist, CMO of DBP. – This is considered to be much more effective than the traditional 3+3 model and is a crucial step in the clinical development of SI-053, as it also decides the recommended optimal dose of SI-053 for Phase II.”

“Model-based designs are known to estimate optimum dose accurately and treat more patients at optimal dose. We are confident that this design will establish a better, i.e. more efficient and safe SI-053 dose, most likely with higher temozolomide content than Temodex, and hence further prolonged overall survival,” – comments Igor Lokot, CEO of Double Bond Pharma.

The model will be based on the data already available for the product and on the software that Cytel has developed in-house and tested in multiple oncology studies. The report generated using this model will be submitted to regulatory authorities, as part of a Phase I clinical trial application for SI-053 in EU.
