Three things to know before you look at the chart.

  1. 01 Lung cancer is the world's deadliest cancer. When chemo and immunotherapy stop working, patients typically have just 2 to 3 months before the cancer keeps growing. There are very few good options left — and the global market for new cancer immunotherapies is worth more than $50 billion a year.
  2. 02 MAIA's drug attacks cancer in a new way. It targets the part of a cancer cell that lets it keep multiplying. In a Phase 2 trial — using MAIA's drug followed by an existing FDA-approved immunotherapy — patients lived a median of 17.8 months, more than double what's typical with standard chemo. Eight patients are still alive past two years.
  3. 03 The FDA gave the drug Fast Track status — a designation reserved for serious diseases with major unmet need, designed to speed up review. The final-stage trial is now enrolling up to 300 patients, and a $33 million raise in March is expected to fully fund it through completion. Early results are expected in 2027.

Important

MAIA's drug is still being tested and has not been approved by the FDA. Trial results so far don't guarantee future results. Investing in a clinical-stage drug company carries real risk of loss, including total loss.
