MiNK Therapeutics ($INKT), a nano-cap clinical-stage biotech firm, shocked the market Friday with a massive surge of over 700%, driven by a landmark cancer remission case published in Nature's Oncogene.
What Happened?
MiNK announced a complete and durable remission in a patient with metastatic, treatment-refractory testicular cancer. The patient had failed multiple prior therapies and received a single infusion of MiNK’s proprietary agenT-797 iNKT cell therapy, combined with Bristol Myers Squibb’s ($BMY) Opdivo (nivolumab).
✅ Outcome: Two years later, no evidence of disease, with the treatment well-tolerated — no cytokine release syndrome (CRS) or graft-versus-host disease (GVHD).
This case marks a critical validation point for agenT-797’s potential in treating solid tumors — a notoriously tough challenge in oncology.
Other Clinical Highlights
At the 2025 AACR Immuno-Oncology meeting, MiNK presented Phase 2 data in second-line gastric cancer:
Signs of immune activation
Tumor infiltration
Early tumor control in checkpoint inhibitor-resistant patients
Several cases of survival beyond 12 months
Another peer-reviewed case in Oncogene described a 42% tumor reduction and 9+ months of progression-free survival in metastatic gastric cancer.
The ongoing Phase 2 trial for gastric cancer is actively enrolling, with more data readouts expected soon.

Investor Takeaway
MiNK’s stunning stock rally is not just hype — it's underpinned by compelling, peer-reviewed clinical data in solid tumors, a field with high unmet needs. While it's early-stage and risks remain (including scalability and future trial results), breakthrough results like this can drive significant upside in nano-cap biotech.
Risk-tolerant investors watching the immuno-oncology space may want to track further trial readouts in gastric cancer and potential strategic interest from larger pharma players.
