$ARTV — Translational Mirror to
$CABA’s Proven Autoimmune Pathway
Artiva Biotherapeutics (
$ARTV) just released early translational data that strongly parallel Cabaletta Bio (
$CABA)’s now clinically validated CAR T results.
• ✅ Complete CD19⁺ B-cell depletion by Day 13
• ✅ Naïve/transitional B-cell repopulation — the same immune “reset” profile seen in
$CABA’s remission patients
• ✅ Favorable safety and community-site administration potential
$CABA’s maturing clinical data (rese-cel / CABA-201) proved the therapeutic effect of deep, transient CD19⁺ depletion — leading to durable autoimmune disease remissions (≥12 months) across lupus, myositis, and systemic sclerosis.
That same depletion biology is now replicated in
$ARTV’s AlloNK platform — suggesting a convergent mechanistic pathway to durable immune reset, but through an off-the-shelf, allogeneic, outpatient cell therapy.

📈 Investor Takeaway
Cabaletta’s results substantially de-risk
$ARTV by validating that the therapeutic mechanism works.
If durability and tissue depletion data align, Artiva could become the scalable NK-cell analog to CABA’s autologous CAR T success.
