FDA Clears TELLOMAK 3 Phase 3 Trial for Lacutamab—IPHA Advances in Rare Cancer Research
Regulatory Milestone Signals Accelerated Approval Path for Rare Cancer Therapy
Innate Pharma (NASDAQ: IPHA, Euronext: IPH) has just received the green light from the FDA to proceed with TELLOMAK 3, its pivotal Phase 3 trial for lacutamab—a first-in-class antibody targeting cutaneous T-cell lymphomas (CTCL), including Sézary syndrome and Mycosis fungoides. This regulatory clearance is a key development for patients with aggressive, rare blood cancers who have exhausted prior therapies and signals that the company's innovation pipeline could soon offer a new standard of care.
Why the FDA Clearance Matters: Opportunity in CTCL Treatment
With CTCL classified as a group of rare non-Hodgkin’s lymphomas that severely affect patient quality of life, treatment options remain limited, especially after first-line therapy fails. Sézary syndrome is particularly aggressive, often leaving clinicians and patients with few choices. By approving the study design with no additional comments, the FDA has acknowledged the unmet need and supported lacutamab’s accelerated regulatory path—setting the stage for possible early access via Accelerated Approval once pivotal trial enrollment begins in 2026.
Phase 3 Trial Design Focuses on Toughest-to-Treat Populations
TELLOMAK 3 is structured as an open-label, randomized trial targeting patients with prior therapy failure. It will enroll two separate cohorts:
- Patients with Sézary syndrome (post-mogamulizumab treatment), randomized to lacutamab or romidepsin.
- Patients with Mycosis fungoides, randomized to lacutamab or mogamulizumab.
The main metric? Progression-free survival, assessed via blinded central review, which is the gold standard for judging if a cancer therapy genuinely improves outcomes in tough-to-treat patient groups.
Promising Phase 2 Data Backed the FDA Decision
Earlier data from the TELLOMAK Phase 2 trial highlighted lacutamab’s durable activity, safety, and positive quality-of-life impact—three pillars that not only motivated this next-phase trial but also helped the drug secure multiple regulatory advantages. These include:
| Regulatory Status | Jurisdiction | Indication |
|---|---|---|
| Fast Track | FDA | Sézary Syndrome |
| PRIME | EMA (Europe) | Sézary Syndrome |
| Orphan Drug | US & EU | CTCL |
| Breakthrough Therapy | FDA | Sézary Syndrome |
Market Perspective: Potential Value Creation on the Horizon
Innate Pharma’s announcement landed while its shares traded at $2.03 as of 11:17 AM, reflecting a sharp move higher as the news circulated. This momentum underlines the market’s recognition of a significant clinical milestone, which, if followed by positive trial results, could accelerate regulatory review and product launch in rare cancer markets with few competitors. Shareholders and prospective investors are watching for continued progress—particularly with a view toward a possible accelerated approval for Sézary syndrome if Phase 3 results match the Phase 2 promise.
| Metric | Value |
|---|---|
| Stock Price (as of 11:17 AM) | $2.03 |

Takeaway: What’s Next for IPHA and Investors?
The FDA’s nod to proceed with TELLOMAK 3 is more than a procedural milestone—it’s a validation of lacutamab’s scientific rationale and clinical potential in some of oncology’s hardest cases. As the trial moves forward, close attention will focus on early data, regulatory updates, and the possibility of an expedited path to market. For those following rare disease innovation or seeking potential catalysts in biotech, Innate Pharma’s progress warrants a place on the radar.
