The Role of High Throughput DSC in Biopharmaceutical Development

The development of biopharmaceuticals demands precise thermal stability characterization to ensure efficacy, safety, and manufacturability. As the industry shifts toward high concentration biologic formulations and subcutaneous delivery methods, the need for innovative DSC solutions becomes increasingly critical.

High concentration biologic formulations are essential for subcutaneous delivery, providing benefits such as improved patient convenience and reduced healthcare costs. However, these formulations present unique challenges in stability testing. Traditional DSC methods often require sample dilution, which can alter the stability profile of the biologic, leading to less reliable data. To ensure accurate thermal characterization, DSC technologies must be capable of analyzing high concentration samples in their native state, without dilution.

Additionally, the rapid growth of biopharmaceutical pipelines demands high-throughput DSC solutions to accelerate drug development. The ability to analyze multiple samples simultaneously not only reduces testing time but also enhances decision-making in candidate selection and formulation optimization.

TA Instruments | Waters Rapid Screening Differential Scanning Calorimeter (RS-DSC) is designed to meet these challenges, offering parallel analysis of up to 24 samples with minimal sample volume. This innovation provides high-throughput capabilities while preserving sample integrity, ensuring robust and reliable biologic drug formulations.

In the candidate selection phase, scientists must rapidly assess multiple biomolecules to identify those with optimal thermal stability and formulation compatibility. The RS-DSC supports this process by providing key thermodynamic data:

• Biomolecule Stability: Measures thermal stability through unfolding transitions.
• T_onset (Onset Temperature): Identifies the temperature at which the biomolecule begins to denature.
• T_max (Melting Temperature): Temperature at which half of the biomolecule population is unfolded.
• Enthalpy (ΔH): Assesses the energy required for thermal unfolding, revealing structural integrity.

By enabling the simultaneous analysis of 24 samples, RS-DSC reduces experimental time, making it ideal for large-scale screening efforts. Unlike traditional capillary DSC systems that require lengthy cleaning and large sample volumes, RS-DSC’s disposable microfluidic chip technology minimizes sample preparation time and eliminates contamination risks.

As biologics transition toward subcutaneous injections, higher concentration formulations become necessary to ensure therapeutic efficacy due to reduced injection volume. However, these high concentrations present several challenges:

• Increased risk of higher order structure, aggregation, precipitation, and phase separation
• Viscosity changes that impact manufacturability and patient administration
• The need for excipients to stabilize biomolecules without compromising activity

The RS-DSC is uniquely suited for evaluating biologic formulations at dosage concentrations (≥ 20 mg/mL – 330+ mg/mL, protein dependent) without the need for dilution. This ensures that researchers can:

• Detect and prevent higher order structure by evaluating stability at real-world concentrations.
• Optimize excipient selection by assessing how buffers, salts, and stabilizers affect biomolecule stability.
• Enhance manufacturability by identifying stable formulations with optimal viscosity profiles.

By combining RS-DSC with TA Instruments rheology techniques, researchers can also assess formulation viscosity and ensure subcutaneous injectability. This makes RS-DSC a powerful tool for accelerating drug development while maintaining regulatory compliance.
