🧬 The
$NWBO Immune OS Was Already Tested: How
#DCVax, RevImmune, and CYT107 Quietly Rewrote Survival in Pediatric Sarcomas
📍
ClinicalTrials.gov: NCT00923351
This was not experimental guesswork.
This was the DCVax method fully implemented, 8 years ago, in pediatric sarcomas.
Led by Crystal Mackall at the NIH, the trial enrolled 43 patients with metastatic or recurrent Ewing sarcoma, rhabdomyosarcoma, and related high-risk tumors.
The immune platform was:
✔️ Tumor lysate from patient biopsy
✔️ Autologous dendritic cells, matured ex vivo
✔️ CD25⁺ Treg-depleted lymphocyte reinfusion
✔️ 6 rounds of vaccination over 10 weeks
✔️ Recombinant IL-7 (CYT107) in Arm B to boost immune recovery
✔️ Cryopreserved tracking and DTH skin testing
✔️ Fully GMP-compatible
This was not a checkpoint inhibitor trial. It was programmable immunotherapy, before the name existed.
📈 Here’s What Happened:
✅ 100% of patients in the vaccine arm mounted a KLH-specific immune response
✅ 62% developed confirmed tumor-specific T-cell responses (ex vivo IFN-γ assay)
✅ Arm B (with IL-7): 57.7% showed positive DTH responses to tumor lysate
✅ 5 of 5 DTH-negative patients were in Arm A (no IL-7)
The immune response was real. And it tracked with survival.
🧬 Survival Data NCT00923351
🎯 Newly Diagnosed Metastatic Ewing/RMS
• 5-Year Overall Survival (Intent-to-Treat): 83.3%
• Prior-generation cohort: 25%
• P = 0.017 when tumor-specific immune response was detected
• Median OS (Arm B): 4.3 years (range: 0.9 to 10.4 years)
• 6 of 6 patients in Arm A survived (100%), though fewer mounted measurable responses
🧪 One patient with over 100 lung metastases remains alive, cancer-free, 7 years later.
“I’d like to see more cancer therapies that apply to stage four metastatic disease… therapies that result in a complete pathologic response, that is, the cancer melts away, without chemo, surgery, or radiation.”
Dr. Marty Makary, FDA Commissioner
🔗 CYT107 Was Not Just a Cytokine. It Was a Strategic Asset.
IL-7 (CYT107) wasn’t a throw-in. It was the terrain calibrator.
And it is owned by RevImmune.
RevImmune is directed by Linda Powers, who is also the CEO of Northwest Biotherapeutics ($NWBO).
This means both the instruction layer (DCVax) and the immune recovery booster (IL-7) were under unified ownership, years before the public understood the stack.
⚙️ The Platform Was Already Fully Aligned:
• Instruction: Autologous tumor antigens
• Compiler: Flaskworks Eden (now GMP-automated)
• Booster: CYT107 terrain recovery (IL-7)
• Execution Sites: Advent (UK), Winterfell (US), C3i (Canada)
• Traceability: GMP, cryogenic recall, automated QC
• Ownership: Linda Powers across instruction and booster class
This is not a speculative system.
It was executed once. The results are public. The infrastructure is now global.
🧠 Strategic Takeaway
This wasn’t an isolated study. It was a real-world execution of programmable dendritic cell immunotherapy across multiple tumor types, with durable survival and 100% immune engagement in KLH assays.
If the tumor is readable, the platform works.
If terrain is supported with IL-7, the immune system responds.
If cryogenic traceability is in place, the network can deploy globally.
The architecture is modular.
The signal has been validated.
The system is already online.
