Coherus Oncology's LOQTORZI Plus Chemotherapy Nearly Doubles 6-Year Survival In Recurrent/Metastatic Nasopharyngeal Carcinoma

Coherus Oncology, Inc. (NASDAQ:CHRS) today announced compelling six-year overall survival (OS) follow-up results from the Phase 3 JUPITER-02 trial evaluating LOQTORZI® (toripalimab-tpzi) plus chemotherapy in recurrent or metastatic nasopharyngeal carcinoma (RM-NPC). The findings reveal a striking and durable survival advantage that underscores the urgent clinical need to incorporate LOQTORZI with chemotherapy as first-line treatment.

In this exploratory post-hoc analysis, patients receiving LOQTORZI plus gemcitabine and cisplatin achieved a median OS of 64.8 months, nearly double that of chemotherapy alone (33.7 months), representing a 31-month improvement and an observed 38% reduction in risk of death (HR 0.62; 95% CI, 0.45–0.85). These results, presented at ESMO Asia 2025, signal a step change in cancer patient survival, reinforcing LOQTORZI's role in transforming outcomes for people living with RM-NPC.

JUPITER-02 is a randomized, double-blind, placebo-controlled Phase 3 study evaluating LOQTORZI with chemotherapy in first-line RM-NPC, and this long-term follow-up provides additional context for the previously reported survival outcomes.

A Meaningful Shift for Patients Who Need It Most

RM-NPC is an aggressive cancer, and long-term survival with standard chemotherapy can be limited for many patients. The multi-year survival observed in the LOQTORZI arm suggests a potential for meaningful clinical benefit, which may translate into longer survival for patients who typically face a challenging prognosis.

"The new 6-year overall survival follow up data gives us even greater confidence to use toripalimab in patients with NPC that is recurrent or metastatic," said Victoria Villaflor, MD, Professor and Director, Head and Neck Oncology Program, Division of Hematology-Oncology, Department of Medicine, UC Irvine School of Medicine.

For many patients, the difference between 33 months and nearly 65 months represents the possibility of more time with family and more milestones. This meaningful extension highlights why oncologists may consider adding LOQTORZI to chemotherapy upfront, as delaying or omitting a therapy associated with improved survival outcomes could reduce a patient's opportunity to achieve longer-term benefit.
