– Conference today at 4:30 p.m. Eastern Daylight Time –
REDWOOD CITY, Calif. and SHANGHAI, China, Oct. 27, 2023 (GLOBE NEWSWIRE) — Coherus BioSciences, Inc. (“Coherus”, NASDAQ: CHRS), and Shanghai Junshi Biosciences Co., Ltd. (Junshi Biosciences, HKEX: 1877; SSE: 688180) today announced that the U.S. Food and Drug Administration (FDA) approved LOQTORZI™ (toripalimab-tpzi) 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. The approval was based on results of the JUPITER-02 Phase 3 study and the POLARIS-02 Phase 2 study and is irrespective of a patient’s PD-L1 status. 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 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.
The safety profile of LOQTORZI was consistent with the PD-1 inhibitor class. The incidence of Grade ≥3 adverse events (AEs) (89.7% vs 90.2%) and fatal AEs (3.4% vs 2.8%) was similar between the two arms. AEs leading to discontinuation of LOQTORZI versus placebo (11.6% vs 4.9%), immune-related adverse events (irAEs) (54.1% vs. 21.7%), and Grade ≥3 irAEs (9.6% vs. 1.4%) were more frequent in the LOQTORZI arm.
In the POLARIS-02 clinical study LOQTORZI demonstrated durable antitumor 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.
NPC is an aggressive cancer that starts in the nasopharynx, the upper part of the throat behind the nose and near the base of skull. 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. LOQTORZI is the first FDA-approved agent for NPC patients.
“LOQTORZI’s first approval is a pivotal event for Coherus as an innovative oncology company. As a next generation PD-1 inhibitor it is the keystone of our I-O strategy to extend cancer patient survival as shown with the impressive results in NPC,” said Denny Lanfear, Chairman and Chief Executive Officer of Coherus. “We are particularly excited to now turn our attention to developing LOQTORZI across multiple tumor types in combination with I-O agents that target the tumor microenvironment, such as our IL27-targeted antibody, casdozokitug, and our CCR8 inhibitor CHS-114, potentially greatly expanding the number of cancer patients achieving improved survival benefit.”
“Today’s FDA approval of LOQTORZI is very encouraging for those living with NPC who currently have very limited treatment options and are in need of new therapies to treat this aggressive and life-threatening form of cancer,” said Jong Chul Park, M.D., Assistant Professor, Harvard Medical School and attending physician at the Center for Head and Neck Cancers at Massachusetts General Hospital Cancer Center. “LOQTORZI is a new treatment option that has demonstrated the ability to significantly improve PFS and OS and should quickly emerge as the new standard of care when used in combination with chemotherapy.”
The recommended LOQTORZI dose with cisplatin and gemcitabine is 240 mg every three weeks until disease progression, unacceptable toxicity, or up to 24 months. The recommended LOQTORZI dose as a single agent for previously treated NPC is 3 mg/kg every two weeks until disease progression or unacceptable toxicity.
LOQTORZI is expected to be available in the United States in Q1 2024.
“The impressive results from JUPITER-02 and POLARIS-02 have provided conclusive evidence that establishes toripalimab, in combination with chemotherapy or as monotherapy, as the standard therapy for advanced NPC,” said Professor Ruihua Xu of Sun Yat-sen University Cancer Center, the principal investigator of JUPITER-02 and POLARIS-02. “This great achievement was only made possible through the solid foundation laid by countless oncology experts over decades of in-depth research, as well as the selfless dedication of the patients and research teams involved in our toripalimab studies. We hope that this promising therapy will close the treatment gap for international NPC patients struggling to find effective therapies, bringing them renewed hope for better survival.”
“We’re excited to reach another significant company milestone of ‘going overseas’,” said Dr. Ning LI, Chief Executive Officer of Junshi Biosciences. “Following etesevimab, toripalimab has become Junshi Biosciences’ second product to receive FDA approval for commercialization—an achievement that will further enhance the company’s international presence. Currently, the establishment of toripalimab’s global commercialization network is in progress, and the network aims to span over 50 countries. In accordance with the company’s ‘In China, For Global’ strategy, we will continue working with our collaborators to promote the commercialization of toripalimab in other regions, in order to provide innovative and high-quality drugs from China to more patients overseas.”
JUPITER-02 is the largest randomized, double-blind, placebo-controlled, international, multi-center Phase 3 clinical study to evaluate a checkpoint inhibitor plus chemotherapy for the first-line treatment of recurrent or metastatic NPC.
Two hundred eighty-nine patients with advanced NPC who had received no prior chemotherapy for recurrent/metastatic disease were randomized 1:1 to receive LOQTORZI (toripalimab-tzpi) 240 mg or placebo in combination with gemcitabine 1000 mg/m2 (days 1 and 8) and cisplatin 80 mg/m2 (day 1) of every three-week treatment cycle, followed by toripalimab-tzpi or placebo monotherapy every 3 weeks until disease progression, intolerable toxicity, or completion of two years of treatment. JUPITER-02 included all eligible patients regardless of PD-L1 status and histologies.
In this study, LOQTORZI met the primary endpoint, demonstrating a significant improvement in PFS (assessed by a Blinded Independent Review Committee (BIRC)) compared to the chemotherapy alone arm with toripalimab-tzpi, reducing the risk of disease progression or death by 48% (HR=0.52 [95% CI: 0.36, 0.74; P<0.0003). Improvement in PFS was observed irrespective of PD-L1 status.
LOQTORZI demonstrated a statistically significant and clinically meaningful improvement in OS with treatment resulting in a 37% reduction in the risk of death versus chemotherapy alone. Median OS has not been reached in the LOQTORZI arm versus 33.7 months for chemotherapy treatment alone (HR=0.63 [95% CI 0.45-0.89]; P=0.0083).
LOQTORZI also demonstrated an improvement in ORR, duration of response (DoR), and DCR. In the study, 77% of patients treated with LOQTORZI experienced a complete or partial response (19% and 58% respectively) and the median duration of response was 10 months in the LOQTORZI arm versus 5.7 months in the chemotherapy alone arm.

Commitment to the NPC community
Given the limited resources available to patients and caregivers contending with NPC, Coherus has launched a new educational community resource, NPCFacts.com, which includes detailed information about the types of NPC as well as its causes, diagnosis, and treatment options.
In addition to education about nasopharyngeal carcinoma, the website includes links to patient-advocacy organizations providing additional resources, including the Head and Neck Cancer Alliance, Support for People with Oral Head and Neck Cancer, and Thyroid Head and Neck Cancer Foundation.
The website includes a companion website for healthcare professionals treating patients with NPC, including educational resources and opportunities for peer-to-peer education.
NPC 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 antitumor immunity demonstrating improvement in the overall survival of cancer patients in several tumor types.
INDICATIONS AND IMPORTANT SAFETY INFORMATION
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).

IMPORTANT SAFETY INFORMATION
Severe and Fatal Immune-Mediated Adverse Reactions
Immune-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.
LOQTORZI 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.
- In patients receiving LOQTORZI monotherapy, immune-mediated pneumonitis occurred in 2.6% (22/851) of patients, including fatal (0.2%), Grade 3 (0.7%), and Grade 2 (1.1%) adverse reactions.

Systemic corticosteroids were required in 12% (4/34) of the patients with immune-mediated dermatologic adverse reactions. Immune-mediated dermatologic adverse reactions resolved in 71% (24/34) of these patients.
Other Immune-Mediated Adverse Reactions
The following clinically significant immune-mediated adverse reactions occurred at an incidence of <1% (unless otherwise noted) in patients who received LOQTORZI or were reported with the use of other PD-1/PD-L1 blocking antibodies. Severe or fatal cases have been reported for some of these adverse reactions.
- Cardiac/Vascular: Myocarditis, pericarditis, vasculitis, pericardial effusion
- Nervous System: Meningitis, encephalitis, myelitis and demyelination, myasthenic syndrome/myasthenia gravis (including exacerbation), Guillain-Barré syndrome, nerve paresis, autoimmune neuropathy
- Ocular: Uveitis, iritis and other ocular inflammatory toxicities can occur. Some cases can be associated with retinal detachment. Various grades of visual impairment, including blindness, can occur. If uveitis occurs in combination with other immune-mediated adverse reactions, consider a Vogt-Koyanagi-Harada-like syndrome, as this may require treatment with systemic steroids to reduce the risk of permanent vision loss.
- Gastrointestinal: Pancreatitis, to include increases in serum amylase and lipase levels, gastritis, duodenitis
- Musculoskeletal and Connective Tissue: Myositis/polymyositis, rhabdomyolysis (and associated sequelae, including renal failure), arthritis, polymyalgia rheumatica, dermatomyositis
- Endocrine: Hypoparathyroidism
- Hematologic/Immune: Hemolytic anemia, aplastic anemia, hemophagocytic lymphohistiocytosis, systemic inflammatory response syndrome, histiocytic necrotizing lymphadenitis (Kikuchi lymphadenitis), sarcoidosis, immune thrombocytopenic purpura, solid organ transplant rejection
LOQTORZI can cause severe or life-threatening infusion-related reactions including hypersensitivity and anaphylaxis.
- In patients receiving LOQTORZI in combination with cisplatin and gemcitabine, infusion-related reactions have been reported in 4.1% of patients, including Grade 2 (0.7%) reactions.
- In patients receiving LOQTORZI monotherapy, infusion-related reactions occurred in 2% of 851 patients, including Grade 3 (0.1%) and Grade 2 (0.6%). LOQTORZI was withheld for one Grade 3 infusion related reaction. Monitor patients for signs and symptoms of infusion-related reactions including rigors, chills, wheezing, pruritus, flushing, rash, hypotension, hypoxemia, and fever. Interrupt or slow the rate of infusion for mild (Grade 1) or moderate (Grade 2) infusion-related reactions. For severe (Grade 3) or life-threatening (Grade 4) infusion-related reactions, stop infusion and permanently discontinue LOQTORZI.
Complications of Allogeneic Hematopoietic Stem Cell Transplant (HSCT)
Fatal and other serious complications can occur in patients who receive allogeneic hematopoietic stem cell transplantation (HSCT) before or after being treated with a PD-1/PD-L1 blocking antibody. Transplant-related complications include hyperacute graft-versus-host-disease (GVHD), acute GVHD, chronic GVHD, hepatic veno-occlusive disease (VOD) after reduced intensity conditioning, and steroid requiring febrile syndrome (without an identified infectious cause). These complications may occur despite intervening therapy between PD-1/PD-L1 blockade and allogeneic HSCT. Follow patients closely for evidence of transplant-related complications and intervene promptly. Consider the benefit versus risks of treatment with a PD-1/PD-L1 blocking antibody prior to or after an allogeneic HSCT.
LOQTORZI can cause fetal harm when administered to a pregnant woman. Animal studies have demonstrated that inhibition of the PD-1/PD-L1 pathway can lead to increased risk of immune-mediated rejection of the developing fetus resulting in fetal death. Advise women of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment with LOQTORZI and for 4 months after the last dose.
There are no data on the presence of toripalimab-tpzi in human milk; its effects on the breastfed child, or on milk production. Maternal IgG is known to be present in human milk. The effects of local gastrointestinal exposure and limited systemic exposure in the breastfed child to toripalimab-tpzi are unknown. Because of the potential for serious adverse reactions in breastfed children, advise lactating women not to breastfeed during treatment with LOQTORZI and for 4 months after the last dose.
