• Tempus AI (NasdaqGS:TEM) reported new study results on its Immune Profile Score (IPS) test.
• The study found IPS can more accurately predict outcomes for patients receiving immunotherapy compared with conventional biomarkers.
• The data suggests IPS may expand access to immune checkpoint inhibitor therapy for patients who are often overlooked, including those with rare cancers and microsatellite stable colorectal cancer.

Tempus AI, which focuses on data driven precision medicine and AI tools for healthcare, is leaning further into cancer care with this IPS study. Immunotherapy is a major focus area for drug developers and clinicians, and any test that can sharpen patient selection tends to attract attention from biopharma partners, hospitals, and payers. For investors, IPS sits at the intersection of diagnostics, oncology, and AI enabled clinical decision support.

Looking ahead, the key questions are how widely IPS gets adopted in clinical practice and whether it is integrated into treatment guidelines or drug label workflows. Investors may watch for updates on regulatory submissions, payer coverage, and collaborations with pharma companies that could look to use IPS in trial design or companion diagnostics.

The IPS update underscores how Tempus AI is trying to make its sequencing business more clinically useful by turning DNA and RNA data into treatment guidance for immunotherapy. By outperforming widely used markers such as tumor mutational burden, microsatellite status, and PD L1 in multiple cancer cohorts, IPS positions Tempus closer to companies like Foundation Medicine, Guardant Health, and Caris that are building test-plus-algorithm offerings for oncologists and biopharma partners.

How this fits the Tempus AI Narrative

This IPS study aligns with the existing Tempus AI narrative that growth is tied to richer oncology data and AI tools that sit on top of that data. Each add-on test that can be run off the same xT and xR assays strengthens the case that Tempus can deepen relationships with health systems and drug companies that want longitudinal, multimodal data to inform trials and real world evidence work.

IPS study, key risks and rewards for investors

• 🎁 IPS sits in a part of the market where payers, oncologists, and pharma companies already spend on precision oncology, which could make add-on adoption easier if clinical utility is recognized.
• 🎁 The ability to flag treatment options for microsatellite stable colorectal cancer and rare tumors reflects Tempus AI's focus on under served niches where competitors may be less established.
• ⚠️ Analysts note that Tempus AI is still unprofitable and requires ongoing investment, so turning IPS into a material revenue stream depends on reimbursement and sustained ordering from clinicians.
• ⚠️ Larger diagnostics and AI players, including companies such as Roche and Exact Sciences, are also investing in immunotherapy biomarkers, which may pressure pricing and require Tempus to keep demonstrating the added value of IPS.

What to watch next

From here, the developments to watch include whether IPS is written into treatment guidelines, included in pharma trial designs, and supported by payer coverage decisions, as those factors tend to influence volume in cancer testing.
