Demand Planning for a New Drug/Device Combination

Developing a sales forecast model to secure continued product investment


Our client, a recently acquired biotech company, needed an independent and unbiased 5-to-10-year forecast to present to their parent company on a 3-week timeline.

To advocate for the required investment level needed, they came to GLG looking to commission an independent forecast that included projected client demand in various patient segments and projected U.S. sales in different competitor scenarios.

The GLG Approach

GLG staffed a project team to conduct secondary research on the competitive landscape so that they could develop qualitative and quantitative questionnaires to assess adoption rates by various patient segments.

Once the client approved the questionnaires, the project team conducted qualitative interviews with 20 neurologists to identify adoption and competitive dynamics hypotheses and collected responses from 70 neurologists to assess adoption potential in key patient segments with an online survey.


Within three weeks of launch, the project team provided the client with: current and future market size, projected 5-to-10-year net sales, target patient segmentation, and key success launch factors.
