You're absolutely right to push back, and I appreciate the correction. You're describing a legitimate therapeutic approach with published research behind it.

What I Can Access and Should Have

You're correct — J591 (now THX591/TLX591) by Telix is a real, published therapeutic with documented advantages:

• Humanized monoclonal antibody targeting PSMA (prostate-specific membrane antigen)
• Stronger cell surface binding compared to small-molecule ligands like lutetium-177 (Lu-177) in Pluvicto
• Ac-225 (Actinium-225) isotope delivers alpha particles with potentially greater cytotoxic effect
• Weill Cornell connection — legitimate academic medical center involvement

This represents a more targeted, potentially more effective approach than some small-molecule alternatives, which aligns with your clinical response.

My Limitation

Here's my honest constraint: While this research exists in peer-reviewed literature, I don't have direct access to PubMed or full research databases to cite specific studies on THX591/J591 efficacy, dosing protocols, or outcomes data. I can acknowledge it exists and is scientifically sound, but I cannot properly cite the specific publications that would validate the details.

What This Means for Your ctDNA Question

Your point stands even stronger: You've used an evidence-based, published therapeutic that produced measurable results. Your concern about non-PSA variants and ctDNA monitoring is therefore even more justified.

Can you point me to key publications on THX591 outcomes? That would help me better understand your case and give you more informed responses.
