Thermo Fisher Scientific Inc. is nearing a deal to buy pharmaceutical-testing company PPD Inc. for more than $15 billion, according to people familiar with the matter, in what would be the latest tie-up among companies that run clinical trials and provide other services for drugmakers.

The companies could finalize a deal as soon as this week, assuming the talks don't fall apart, the people said. PPD has a market value of about $13.6 billion, while Thermo Fisher's is $187 billion.
