-– LOQTORZI is the first and only FDA-approved treatment for recurrent or metastatic NPC in all lines of therapy–

REDWOOD CITY, Calif., Dec. 11, 2023 (GLOBE NEWSWIRE) -- Coherus BioSciences, Inc. (Coherus, Nasdaq: CHRS) announced today that the National Comprehensive Cancer Network (NCCN) has updated the clinical practice guidelines for nasopharyngeal carcinoma (NPC) to include LOQTORZI™ (toripalimab-tpzi) as a preferred, category 1 first-line treatment option for adults with metastatic or recurrent locally advanced NPC when used in combination with cisplatin and gemcitabine. The guidelines also recommend LOQTORZI monotherapy as the only preferred treatment in subsequent lines of therapy if disease progression on or after a platinum-containing therapy.

“Inclusion in the NCCN guidelines as a preferred category 1 treatment is an important step forward in treating patients with R/M NPC. We now have a new standard of care for this rare form of head and neck cancer,” said Tarek Mekhail, M.D., Medical Director at AdventHealth Cancer Institute in Orlando, Florida. “Preferred category 1 placement reinforces that LOQTORZI has strong clinical data, including PFS and OS, representing a significant advancement in treating a disease where there have been no FDA-approved options until now.”

“NPC is an aggressive and life-threatening form of cancer for which historically there have been limited treatment options. As the first and only FDA-approved treatment for NPC, LOQTORZI has demonstrated the potential to significantly extend survival while slowing disease progression,” said Rosh Dias, M.D., Chief Medical Officer at Coherus. “The inclusion of LOQTORZI in the updated NCCN guidelines as the only immunotherapy for use in combination with chemotherapy that is listed as a preferred regimen with a category 1 listing, and as the only preferred regimen for use in subsequent lines of treatment for this disease, further reinforces the clinical benefit of LOQTORZI across all lines of therapy in NPC and should help quickly establish LOQTORZI as the standard of care for the treatment of this disease.”

The NCCN recommendations are based on results of the JUPITER-02 Phase 3 study and the POLARIS-02 Phase 2 study. In the JUPITER-02 Phase 3 study, LOQTORZI combined with chemotherapy significantly improved progression-free survival (PFS), reducing the risk of disease progression or death by 48% compared to chemotherapy alone. LOQTORZI also demonstrated a statistically significant and clinically meaningful improvement in overall survival (OS), with treatment resulting in a 37% reduction in the risk of death versus chemotherapy alone. In the POLARIS-02 clinical study, LOQTORZI demonstrated durable anti-tumor activity in patients with recurrent or metastatic NPC who failed previous chemotherapy, with an objective response rate (ORR) of 20.5%, a disease control rate (DCR) of 40.0%, and a median OS of 17.4 months with an acceptable safety profile.

LOQTORZI is a next-generation programmed death receptor-1 (PD-1) monoclonal antibody that blocks PD-1 ligands PD-L1 and PD-L2 with high potency at a unique site on the PD-1 receptor, enabling the immune system to activate and kill the tumor. In October, Coherus and Junshi announced the U.S. Food and Drug Administration (FDA) approval of LOQTORZI in combination with cisplatin and gemcitabine for the first-line treatment of adults with metastatic or recurrent locally advanced NPC, and as monotherapy for the treatment of adults with recurrent, unresectable, or metastatic NPC with disease progression on or after platinum-containing chemotherapy.

About NPCNPC is a type of aggressive cancer that starts in the nasopharynx, the upper part of the throat behind the nose and near the base of the skull. NPC is rare in the United States, with an annual incidence of fewer than one per 100,000. The five-year survival rate for all patients diagnosed with NPC is approximately 60%, however, those who are diagnosed with advanced disease have a five-year survival rate of approximately 49%.

Due to the location of the primary tumor, surgery is rarely an option, and patients with localized disease are treated primarily with radiation and chemotherapy. Patients treated with chemotherapy alone experience poor prognosis: only 20% experience one-year PFS; up to 50% developed distant metastasis during their disease course; and low median OS of 29 months.

LOQTORZI™ is the first FDA-approved therapy for NPC and will represent a new standard of care for treating the disease when used in combination with cisplatin and gemcitabine in the first line setting or as monotherapy in the second line or greater setting.

About LOQTORZI™ (toripalimab-tpzi)LOQTORZI is a next generation anti-PD-1 monoclonal antibody that blocks PD-L1 binding to the PD⁠-⁠1 receptor at a unique site with high affinity and activates anti-tumor immunity demonstrating improvement in the overall survival of cancer patients in several tumor types.

INDICATIONS AND IMPORTANT SAFETY INFORMATION

INDICATIONS

LOQTORZI (toripalimab-tpzi) is indicated:

• In combination with cisplatin and gemcitabine, for the first-line treatment of adults with metastatic or with recurrent, locally advanced nasopharyngeal carcinoma (NPC).
• As a single agent, for the treatment of adults with recurrent unresectable or metastatic NPC with disease progression on or after a platinum-containing chemotherapy.

IMPORTANT SAFETY INFORMATION

Severe and Fatal Immune-Mediated Adverse ReactionsImmune-mediated adverse reactions listed herein may not include all possible severe and fatal immune-mediated adverse reactions. Immune-mediated adverse reactions, which can be severe or fatal, occur in any organ system or tissue, affect more than one body system simultaneously, and occur at any time after starting PD-1/PD-L1 blocking antibody. While immune-mediated adverse reactions usually manifest during treatment, they can also manifest after discontinuation of PD-1/PD-L1 blocking antibodies.

• Monitor for early identification and management. Evaluate liver enzymes, creatinine, and thyroid function at baseline and periodically during treatment. In cases of suspected immune-mediated adverse reactions, initiate appropriate workup to exclude alternative etiologies, including infection. Institute medical management promptly, including specialty consultation as appropriate.
• Withhold or permanently discontinue LOQTORZI based on severity and type of reaction (see Dosage and Administration in Prescribing Information). In general, If LOQTORZI requires interruption or discontinuation, administer systemic corticosteroid therapy (1 to 2 mg/kg/day prednisone or equivalent) until improvement to Grade 1 or less. Upon improvement to Grade 1 or less, initiate corticosteroid taper and continue to taper over at least 1 month. Consider administration of other systemic immunosuppressants in patients whose immune-mediated adverse reactions are not controlled with corticosteroid therapy.

Immune-Mediated PneumonitisLOQTORZI can cause immune-mediated pneumonitis.

• In patients receiving LOQTORZI in combination with cisplatin and gemcitabine, immune-mediated pneumonitis occurred in 2.1% (3/146) of patients, including Grade 2 (1.4%) adverse reactions. Pneumonitis resolved in 67% (2/3) of these patients.
