Scientists in specialized roles like immunogenicity risk becoming siloed service providers. To maintain impact and growth, they must proactively collaborate with other functions like CMC, safety, and quality. This provides a holistic view of drug development and integrates their expertise into the entire process.
Bi-specific T-cell engagers (BiTEs) are highly immunogenic because the mechanism activating T-cells to kill cancer also primes them to mount an immune response against the drug itself. This 'collateral effect' is an inherent design challenge for this drug class.
Dr. Vibha Jawa's career shows a powerful strategy: learning drug development fundamentals in large companies (Amgen, Merck) and applying them in nimble startups. This cycle across different environments accelerates learning and deepens expertise in a specialized field like immunogenicity.
The future of medicine isn't about finding a single 'best' modality like CAR-T or gene therapy. Instead, it's about strategic convergence, choosing the right tool—be it a bispecific, ADC, or another biologic—based on the patient's specific disease stage and urgency of treatment.
Modern, highly sensitive assays often detect high rates of anti-drug antibodies (ADAs). However, the critical question for drug developers isn't the ADA incidence rate itself, but whether that immune response actually impacts drug exposure, efficacy, or overall patient outcome.
Non-human primate models are poor predictors of human immunogenicity. The industry has shifted to human-relevant ex vivo assays using whole blood or PBMCs. These tests can assess risks like complement activation upfront, enabling proactive protein engineering to improve a drug's safety profile.
