Investigate a problem · Illustrative example
Development has hit a problem.
Understand a batch difference before repeating work or changing the plan.
Fictional scenario for discussion. This is not a client engagement, an actual DEP deliverable, or a reported result. The work and outputs described would depend on an agreed scope.
The situation
Two batches of the same compound behave differently in a formulation study. Repeating the study is one suggestion; changing the formulation is another. The cause has not been established.
What the team would examine
DEP’s team would bring together the relevant drug-substance, analytical, solid-form, and formulation expertise. They would compare available batch records, characterization, and study conditions, identifying what is comparable and where information is missing.
How the reasoning changes the plan
In this fictional scenario, the available records do not establish whether the material and study conditions were comparable. The team would recommend a focused comparison to test the competing explanations before selecting a formulation change or a repeat study. No cause or successful outcome is assumed.
What you would receive under the proposed scope
A proposed investigation plan connecting each question to the information needed, the specialist responsible, and the decision the findings would support.
Your decision
You review the scope and authorize the investigation. The team would revisit the recommendation when the findings are available.
