K241868 is an FDA 510(k) clearance for the xR IVD. Classified as Next Generation Sequencing Based Tumor Profiling Test (product code PZM), Class II - Special Controls.

Submitted by Tempus AI, Inc. (Chicago, US). The FDA issued a Cleared decision on September 19, 2025 after a review of 449 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Pathology FDA review panel, regulated under 21 CFR 866.6080 - the FDA pathology device framework. The Traditional 510(k) pathway establishes clearance through substantial equivalence to a legally marketed predicate device, without requiring clinical trial data.

Device pattern: High-complexity regulatory submission. Elevated predicate reliance profile. The extended review timeline suggests the FDA required additional documentation before confirming substantial equivalence - a pattern common in complex or first-of-kind Pathology submissions.

Device Classification

Product Code PZM Next Generation Sequencing Based Tumor Profiling Test
Device Class Class 2 - Special Controls
CFR Regulation 21 CFR 866.6080
Definition A Next-generation Sequencing Based Tumor Profiling Test Is A Qualitative In Vitro Diagnostic Test Intended To Detect Mutations In A Broad Panel Of Targeted Genes That Are Somatically Altered In Malignant Neoplasms From Tumor Specimens Obtained From Patients Diagnosed With Malignant Solid Neoplasms Using Targeted Next-generation Sequencing.
What this classification means

Class II devices require demonstration of substantial equivalence to a legally marketed predicate device. This pathway does not require clinical trials - it relies on engineering equivalence and performance data. Most Pathology devices follow this clearance model.
