The use of bulk containers for supplying phase I drug products is indicative of the nature of early-phase trials, where the focus is primarily on assessing safety outcomes and pharmacokinetics rather than extensive packaging. In phase I studies, it is common to supply larger volumes of the drug in bulk to enable the clinical research team to dispense the medication as needed throughout the trial, particularly as dosage adjustments may be required based on early findings.

Bulk containers allow for efficient handling and distribution in a clinical setting, where multiple participants may be involved. This method provides flexibility in dosing, as it allows the research team to draw from a larger supply to create individualized doses for each participant, which can be particularly important during the initial stages of drug development.

The other options, such as single-dose ampoules, pre-packaged blister packs, and individual vials, are typically more suited for later-phase studies where the dosing regimen is well-established and the need for precise, patient-specific dosages is greater. These packaging methods are aimed at minimizing the risk of dosing errors and improving patient compliance, which is less of a primary concern in the exploratory phase of research.
