We are HEPHAISTOS
Unlocking Immunity
HEPHAISTOS is a biopharmaceutical company developing 3rd generation innate immune boosters designed to convert myeloid-rich tumors into immunotherapy responsive tumors.
The lead drug-candidate HEPHA 440 has demonstrated compelling anti-tumor activity in a broad spectrum of preclinical models of cancers, both as single agent and in combination with other immunotherapies. The drug also demonstrated favorable tolerability and a broad therapeutic window predicting safe and efficacious systemic administration in humans.
HEPHA 440 is scheduled to enter clinical trials in 2027.
HEPHAISTOS is advancing next generation TLR4 agonist with high-therapeutic-index for front-line cancer therapy.

Overcoming resistance to immunotherapy
The biggest challenge in oncology
Many patients still fail to derive durable benefit from immunotherapy because tumors can evade immune surveillance and establish a microenvironment with Myeloid cells that suppresses effective anti-tumor immunity. HEPHA-440 act simultaneously on two anti-tumor mechanisms:
1. Primary activation of innate immunity
-
- M2 to M1 macrophages conversion
- TME remodeling from cold to hot tumors
- Induction of tumor antigen presentation by DCs
2. Secondary activation of adaptive immunity
-
- Recruitment and priming of CD8+ T Cells
- Immune-memory against tumor recurrence
- Systemic anti-tumor and metastases immune effect
HEPHA440 activates innate and adaptive immune responses with significant systemic anti-tumor potential.
Publications
In preclinical studies, HEPHA440 demonstrated compelling anti-tumor activity with deep and durable responses and induced a memory effect through its unique mode of action of recruiting CD8 T cells, activating antigen presentation, and converting M2 to M1 macrophages. Through TME remodeling, HEPHA440 has the potential to overcome myeloid cell-based immune-suppression and unleash the full potential of immune checkpoint inhibitors.
