Alligator Bioscience benefits from Cobra’s maxXpress platform

Cobra developed the cell line to express agonistic CD40 antibodies for an immuno-oncology application using its maxXpress platform

Cobra Biologics has developed a cell line for Alligator Bioscience, a Swedish biotechnology company, expressing monoclonal antibodies for a phase 1 clinical trial that commenced in April. Cobra developed the cell line to express agonistic CD40 antibodies for an immuno-oncology application using its maxXpress platform, which harnesses the power of ubiquitous chromatin opening element (UCOE) technology.

Combined with Cobra’s experienced cell line development team, and the added benefit of the Ambr robotic system, the platform enables the rapid production of correctly folded and glycosylated recombinant proteins, complimented by Cobra’s in-house cell-based potency assays and high resolution mass spectrometry analytical capability.

The maxXpress service can assess up to nine constructs at a time and can generate purified mixed clonal pool material in just 10 weeks.

The study, led by Alligator Bioscience, will determine the safety, pharmacokinetics and pharmacodynamics of intratumourally administered ADC-1013, enrolling up to 40 patients during the dose escalation and expansion phases at five centres in the United Kingdom, Denmark and Sweden.

Peter Coleman, CEO, Cobra Biologics, commented: ‘I am delighted that we have had the opportunity to work with Alligator on this promising clinical programme and would like to congratulate the team on their success to date. Cobra has been manufacturing protein therapeutics since 1995 and our maximum protein expression platform, maxXpress, has proven to be very popular to customers looking for both speed and quality.’

Dr Per Norlén, CMO and VP Development Alligator Bioscience, commented: ‘ADC-1013 has been found to have good developmental properties; a very pure and stable drug product has now been successfully administered to patients.’
