QSP 建模优化多发性骨髓瘤疗法的首次人体试验剂量选择

When preparing for first-in-human (FIH) clinical trials of ISB 2001 (NCT05862012), IGI faced a significant challenge. Translating preclinical data from animals to humans often leads to an overly conservative Minimum Anticipated Biological Effect Level (MABEL) approach for dose selection. While safe, this can result in suboptimal dosing in the trial’s initial phases, unnecessarily prolonging the timeline and escalating costs. IGI needed a proven framework to determine the most appropriate therapeutic dose for their tri-specific T-cell engager.

Certara’s Quantitative Systems Pharmacology (QSP) Center of Excellence collaborated with IGI to address the challenge. The team built a specialized QSP model for ISB 2001, leveraging their extensive biosimulation and oncology dose optimization expertise.

Key highlights of their solution include:

Developing Precision Models: Certara’s model used a Minimal Pharmacologically Active Dose (MPAD) approach. Compared to the traditional MABEL approach, this model allowed for a 50-100 times higher dose.

Regulatory Acceptance: This new approach received approvals from regulatory bodies, such as the US FDA and Australia’s HREC, supporting FIH dose determination for other TCEs as well.

The implementation of this QSP model ensured the following benefits for IGI’s clinical trial process:

Optimized Dose Selection: A higher starting dose reduced the number of patients exposed to subtherapeutic levels, enhancing efficacy evaluation in early trial phases.

Streamlined Timelines: By accelerating dose optimization, IGI minimized the overall duration and cost of the trial.

These advancements solidified IGI’s position as a trailblazer in tri-specific TCE therapy, getting life-saving treatments to patients faster.
