Patients didn't become marathon runners, but many went from needing help getting dressed to managing independently. The treatment appeared safest in patients under 80, raising questions about the upper age limit for effectiveness.</p><p style="margin: 0 0 8px 0;">This marks the first time stem cells have shown consistent benefits for frailty itself, not just specific diseases that cause it. The approach targets the underlying cellular aging process rather than treating symptoms after they appear. If larger trials confirm these findings, it could offer the first treatment for a condition affecting 15% of Americans over 65 β one that currently has no medical therapy beyond "try to exercise more."</p><p style="margin: 0 0 8px 0;">The company plans Phase III trials later this year, which would test effectiveness in roughly 400-600 patients and move the treatment closer to FDA approval.</p></div></div><div class="rw-section" style="border: 1px solid #E5E7EB;
