$ATNM BIG ATNM-400 development. New EANM’26 abstracts confirm ATNM-400 has entered first-in-human clinical development. The Phase 1 mCRPC study says dose escalation is ongoing, with interim human safety, PK, biodistribution and dosimetry data to be presented at EANM. RADIANZ is also enrolling across 5 solid tumors: prostate, NSCLC, breast, colorectal & ovarian. October deck still guides to initial human biodistribution/safety data + target disclosure in Q4. EANM: Oct 17–21. Target remains undisclosed. Human data are coming.

$ATNM From this stock value, the only way out is with favorable phase 1 data, that's all that's needed. I expect Selt to present that data in the coming days.

$ATNM Personally, I don’t think the new Zacks coverage is particularly realistic or fully up to date. They still have the shareholder lawsuit listed as active for a start. More importantly, their valuation essentially gives ATNM-400 very little credit by assigning it just a 7% probability of success — despite ATNM-400 now being Actinium’s lead program and the company guiding to initial human PK/PD, dosimetry, biodistribution/safety and early pan-cancer POC by YE26. They also assume 11M additional shares of future dilution, taking their valuation share count to ~42.2M. So I don’t put much weight on the $4 target.

$ATNM To those wise enough to buy at $0.75 on 8/5, you are about to get a 100% return. If you are patient, you'll probably get 1000% return in a few more months. And if patience is your thing, who knows 10,000% awaits! What's the saying? Patience is a virtue!

$ATNM H.C. Wainwright deck has a meaningful ATNM-400 update. The prior September deck said: “2H:26 initial tumor targeting and biodistribution data.” The new Sept. 11 Wainwright deck is much more specific: • Q4:26 target disclosure at a medical conference • Q4:26 demonstration of pan-cancer potential • Q4:26 KOL webinar • Q4:26 initial biodistribution and safety data in prostate cancer • Initial HUMAN PK/PD and dosimetry data, early pan-cancer POC and additional translational data expected by YE:26 That last line is the standout. This is no longer framed simply as more preclinical work. Management is explicitly guiding to human PK/PD and dosimetry data by year-end. They also changed the ATNM-400 slide title from “Differentiated Radiotherapy Targeting 3 Blockbuster Indications” to “Pan Cancer Radiotherapy Targeting 3 Blockbuster Indications” and added “NOT PSMA” to emphasize differentiation.

$ATNM Maybe Seth will share some info on Actinium225 production at the investor presentation Monday. He could give insight on the current status, near term plans, and potential over the next year. This is just as big as anything in the pipline. And put up a big colorful one month stock chart where the presentation is being made so anyone interested can see.

$ATNM ⭐ Why this matters for M&A Your tab shows Merck’s CMO saying: “interest but little urgency until the mechanisms of benefit are better understood.” Translation: ✔ Merck knows ADCs cannot solve cold tumors ✔ Merck knows Keytruda cannot solve cold tumors ✔ Merck knows vaccines cannot solve cold tumors ✔ Merck knows KRAS cannot solve cold tumors ✔ Merck knows they need a new modality ✔ Merck does not have it ✔ Merck does not understand it ✔ Merck is waiting for someone else to explain it That “someone else” is ATNM.

$ATNM Merck owns intismeran. They own Keytruda. They need to own ATNM. The vaccine population is the clearest demonstration of why — it is the patient population where Merck's existing assets and ATNM's assets combine into an exclusive commercial ecosystem that no other company can replicate.

$ATNM Timing is hard to predict if your on the outside looking in. Price doesn't always reflect value. Now if you have a better set of posts and information, I am waiting for yours.

$ATNM Cut and paste from a promotional email I received. Almost always I do not even open these! This does make sense though - “That said, there is one sector that’s been roaring for a year and a half, and odds are you haven’t heard much about it. It hasn’t commanded the spotlight like AI chipmakers or gold. It hasn’t sparked a social media frenzy. And yet, measured from its April 2025 low, it has more than doubled. The good news is that, if you’ve missed it, the evidence suggests this bull still has plenty of juice left in it. I’m talking about biotech. Today, let’s look at how to position for it. A bull hiding in plain sight While there are many ways to play biotech, let’s use the State Street SPDR S&P Biotech ETF (XBI) as our proxy for the sector. It’s the go-to benchmark for small- and mid-cap biotech stocks. (Contd)

$ATNM Lets see what comes out of the Conference on Monday. Seth's time slot is between 3:00 pm and 3:30 PM. The stock has almost doubled from its Aug 3 low of .74 until its high today of $1.44. We are definitely in overbought territory.

$ATNM From AI “The Problem: MDSCs and Immune Evasion MDSCs are immature immune cells recruited by tumors to create an immunosuppressive tumor microenvironment (TME). They block anti-tumor immune responses from T cells, B cells, and Natural Killer (NK) cells, acting as a shield that prevents immunotherapies (like checkpoint inhibitors) from working effectively. The Solution: CD33 Targeted Depletion • Targeting CD33: Both monocytic and granulocytic MDSCs uniformly express the CD33 antigen on their cell surface. • Mechanism of Action: Actimab-A consists of the CD33-targeting monoclonal antibody lintuzumab conjugated to an Ac-225 alpha-particle emitting payload. When it binds to the CD33 receptor on MDSCs, it delivers localized alpha radiation, inducing lethal, double-stranded DNA breaks that selectively kill and deplete the MDSCs. Reversing Resistance: By eliminating MDSCs from the solid tumor microenvironment, Actimab-A reduces immune suppression and restores local T-cell immunity.
