Title: Recurrent Pancreatic Cancer Treated with N-803 and PD-L1 t-haNK Followed by an EGFR-targeted Nanocell Drug Conjugate
Published in: The Oncologist, March 2024
Link to article

Summary of the Case Study This is a detailed compassionate-use report of a patient with recurrent metastatic pancreatic cancer (mPC) who had already failed three prior lines of therapy.

First spIND protocol:
  • Therapies used:

    • N-803 (IL-15 superagonist to activate NK and CD8+ T cells)

    • PD-L1 t-haNK cells (engineered NK cells with high-affinity CD16 targeting PD-L1 for enhanced ADCC)

    • Aldoxorubicin (albumin-doxorubicin conjugate to improve tumor-targeted chemotherapy)

  • Treatment duration: ~27 months

  • Clinical result:

    • Stable disease was achieved.

    • A transient complete response was observed by ~14 months into therapy.

Second spIND protocol (post-progression):
  • Therapies used:

    • E-EDV-D682 + EDV-GC, components of the EGFR-targeted nanocell delivery system

  • Duration: Over 24 months

  • Outcome: Maintained stable disease, with the patient still alive at the time of publication.

Evaluation Scientific and Clinical Significance
  • Exceptional Duration of Disease Control: Total of more than 4 years (27 months first-line + >24 months second-line) of disease stability in advanced pancreatic cancer, which is notoriously resistant to treatment.

  • Immunotherapy + Targeted Delivery Synergy:

    • The case demonstrates how sequential or combinatory regimens using engineered NK cells, immune-stimulatory cytokines, and targeted chemotherapy nanocells may extend survival and control tumor progression in difficult-to-treat cancers.

  • Evidence of Activity: A complete response, even if transient, is rare in metastatic pancreatic cancer after third-line failure and may suggest significant immunologic engagement by IBRX’s technologies.

Limitations
  • Single-patient case report: Results cannot be generalized. There’s no control group, and spontaneous stabilization cannot be ruled out (though unlikely).

  • Need for Clinical Trials: Further validation in controlled, multi-patient trials is necessary to determine real-world applicability and reproducibility.

Significance for IBRX (ImmunityBio) Investors This case supports the clinical relevance of IBRX’s core immunotherapy platform, especially:

  • N-803 (Anktiva), which is currently in multiple trials (e.g., bladder cancer, NSCLC, and other solid tumors).

  • PD-L1 t-haNK cells, which offer a dual targeting approach (NK activation + checkpoint modulation).

  • Targeted nanocell conjugates (e.g., EDV platforms), which may provide a next-generation drug delivery system especially when combined with immunotherapies.

Investor Takeaways:
  • Validation of Platform: Demonstrates long-term disease control even after multiple therapy failures, reinforcing IBRX’s platform potential.

  • Durability: Highlights a major differentiator versus many checkpoint-only approaches.

  • Catalyst for Partnerships: The combination of immunotherapy and targeted delivery could attract strategic partnerships or expanded trials.

  • Support for Expansion: If replicated, could justify new indications beyond bladder cancer and increase the addressable market for IBRX technologies.

Conclusion This compassionate use case, while limited to a single patient, presents powerful anecdotal evidence supporting IBRX’s immunotherapy and drug delivery platforms in an extremely resistant cancer. For long-term IBRX investors, it affirms the underlying scientific thesis and suggests significant upside if further trials corroborate these findings.
