Patient card All prescribers of LOQTORZI should inform patients about the patient card, explaining what to do should they experience any symptom of immune-related adverse reactions. The physician will provide the patient card to each patient. Special populations Elderly No dose adjustment is recommended for patients who are aged 65 years or over (see section 5.2). Renal impairment No dose adjustment is needed for patients with mild or moderate renal impairment. There are insufficient data in patients with severe renal impairment for dosing recommendations (see section 5.2). Hepatic impairment No dose adjustment is recommended for patients with mild hepatic impairment. There are insufficient data in patients with moderate or severe hepatic impairment for dosing recommendations (see section 5.2). Paediatric population The safety and efficacy of LOQTORZI in children and adolescents aged under 18 years have not been established. No data are available. Method of administration LOQTORZI is for intravenous use only and must be administered by infusion. The first infusion should be administered over 60 minutes via an infusion pump through an in-line filter (0.2 micron or 0.22 micron pore size). If no infusion-related reactions occurred during the first infusion, subsequent infusions may be administered over 30 minutes. When administered on the same day as chemotherapy, LOQTORZI should be administered prior to chemotherapy through a different intravenous line. For instructions on dilution of the medicinal product before administration, see section 6.6.

Traceability In order to improve the traceability of biological medicinal products, the name and the batch number of the administered product should be clearly recorded. Immune-related adverse reactions Immune-related adverse reactions, which may be severe or fatal, can occur in patients treated with antibodies blocking the programmed cell death protein-1 / programmed death-ligand 1 (PD-1/PD-L1) pathway, including toripalimab. While immune-related adverse reactions usually occur during treatment with PD-1/PD-L1 blocking antibodies, symptoms can also manifest after discontinuation of treatment. Immune-related adverse reactions may occur in any organ or tissue and may affect more than one body system simultaneously. Important immune-related adverse reactions listed in this section are not inclusive of all possible severe and fatal immune-related reactions. Early identification and management of immune-related adverse reactions are essential to ensure safe use of PD-1/PD-L1 blocking antibodies. Patients should be monitored closely for symptoms and signs of immune-related adverse reactions. Clinical chemistries including liver enzymes, creatinine, and thyroid function should be evaluated at baseline and periodically during treatment. In cases of suspected immune-related adverse reactions, appropriate workup should be initiated to exclude alternative aetiologies, including infection. Medical management should be instituted promptly, including specialty consultation as appropriate. Toripalimab should be withheld or permanently discontinued depending on the type and severity of the adverse reaction (see section 4.2). If treatment with toripalimab should be withheld or permanently discontinued, administer systemic corticosteroid therapy (1 to 2 mg/kg/day prednisone or equivalent) until improvement to Grade 1 or less. If myocarditis is suspected, initiate high-dose steroids (e.g., methylprednisolone 1 g/day intravenously for 3–5 days). Upon improvement to Grade 1 or less, initiate corticosteroid taper. Consider administration of other systemic immunosuppressants in patients whose immune-related adverse reactions are not controlled with corticosteroid therapy. Hormone replacement therapy for endocrinopathies should be instituted as warranted. Treatment with toripalimab may be restarted within 12 weeks after last dose of toripalimab if the adverse reaction recovers to Grade =1 and corticosteroid dose has been reduced to = 10 mg prednisone or equivalent per day. Treatment with toripalimab must be permanently discontinued for any Grade 3 immune-related adverse reaction that recurs and for any Grade 4 immune-related adverse reaction toxicity, except for endocrinopathies that are controlled with replacement hormones (see sections 4.2 and 4.8). Toxicity management guidelines for adverse reactions that do not necessarily require systemic steroids (e.g., endocrinopathies and skin reactions) are discussed below. Immune-related pneumonitis Toripalimab can cause immune-related pneumonitis (see section 4.8). Patients should be monitored for signs and symptoms of pneumonitis. Suspected pneumonitis should be confirmed with radiographic imaging and other causes excluded. Patients should be managed with toripalimab treatment modifications and corticosteroids, as clinically indicated (see section 4.2 and directions for corticosteroid treatment in section 4.4 above). Immune-related colitis Toripalimab can cause immune-related colitis, which may present with diarrhoea (see section 4.8). Patients should be monitored for signs and symptoms of colitis and managed with toripalimab treatment modifications, anti-diarrhoeal agents and corticosteroids, as clinically indicated (see section 4.2 and directions for corticosteroid treatment in section 4.4 above). In cases of corticosteroid-refractory colitis, consider repeating infectious workup to exclude alternative aetiologies. Cytomegalovirus (CMV) infection/reactivation has been reported in patients receiving other PD-1/PD-L1 blocking antibodies with corticosteroid-refractory immune-related colitis. Hepatotoxicity and immune-related hepatitis Toripalimab can cause immune-related hepatitis (see section 4.8). Patients should be monitored for changes in liver function periodically and as indicated, based on clinical evaluation. Patients should be managed with toripalimab treatment modifications (see sections 4.2) and corticosteroids, as clinically indicated (see directions for corticosteroid treatment in section 4.4 above). Immune-related endocrinopathies Adrenal insufficiency Toripalimab can cause primary or secondary adrenal insufficiency (see section 4.8). Patients should be monitored for clinical signs and symptoms of adrenal insufficiency. For Grade 2-4 adrenal insufficiency, toripalimab should be withheld until patient is clinically stable on physiologic hormone replacement therapy (see section 4.2). Hypophysitis Toripalimab can cause immune-related hypophysitis (see section 4.8). Hypophysitis can present with acute symptoms associated with mass effects such as headache, photophobia, or visual field defects. Hypophysitis can cause hypopituitarism. Patients should be monitored for signs and symptoms of hypophysitis. For Grade 2-4 hypophysitis, toripalimab should be withheld until patient is clinically stable on physiologic hormone replacement therapy (see section 4.2). Thyroid disorders Toripalimab can cause immune-related thyroid disorders (see section 4.8). Patients should be monitored for signs and symptoms of thyroid disorders prior to and periodically during treatment, and as indicated based on clinical evaluation. Hypothyroidism may be managed with replacement therapy without toripalimab interruption and without corticosteroids (see section 4.2). Thyroiditis can present with or without concomitant thyroid dysfunction. Thyroiditis and hyperthyroidism may be managed symptomatically which may include thyroid suppression and/or corticosteroid therapy for acute thyroiditis. Toripalimab should be withheld for Grade = 3 thyroiditis or hyperthyroidism until controlled with medical management and patient is clinically stable. Patients should be monitored for hypothyroidism that may follow hyperthyroidism or thyroiditis. Thyroid function and hormone levels should be monitored to ensure appropriate hormone replacement. Type 1 diabetes mellitus, which can present with diabetic ketoacidosis Toripalimab can cause immune-related type I diabetes mellitus (see section 4.8). Patients should be monitored for hyperglycaemia or other signs and symptoms of diabetes. Insulin treatment should be initiated for type I diabetes mellitus as clinically indicated and toripalimab should be withheld in patients with Grade = 3 hyperglycaemia. Treatment with toripalimab may be resumed when diabetes is controlled with medical management including insulin therapy and the patient is clinically stable (see section 4.2). Immune-related nephritis Toripalimab can cause immune-related nephritis (see section 4.8). Patients should be monitored for changes in renal function and other causes of renal dysfunction excluded. Toripalimab treatment should be modified (see section 4.2) and corticosteroids instituted, as clinically indicated (see instructions for corticosteroid treatment in section 4.4 above). Immune-related skin adverse reactions Toripalimab can cause immune-related rash or dermatitis (see section 4.8). Exfoliative dermatitis, including Stevens-Johnson Syndrome, drug rash with eosinophilia and systemic symptoms, and toxic epidermal necrolysis, has been reported in patients receiving PD-1/PD-L1 blocking antibodies. Patients should be monitored for skin adverse reactions and managed with toripalimab treatment modifications (see section 4.2) and corticosteroids, as clinically indicated (see instructions for corticosteroid treatment in section 4.4 above). Immune-related myocarditis Toripalimab can cause immune-related myocarditis (see section 4.8). Patients should be monitored for signs and symptoms of myocarditis. If myocarditis is suspected, high-dose steroids should be promptly initiated and prompt cardiology consultation with diagnostic workup according to current clinical guidelines should be started. Patients should be managed with toripalimab treatment modifications (see section 4.2) and corticosteroids, as clinically indicated (see instructions for corticosteroid treatment in section 4.4 above). Consider addition of immunosuppressants if the event does not improve within 48 hours after start of corticosteroid therapy. Immune-related myositis Toripalimab can cause immune-related myositis (see section 4.8). Patients should be monitored for signs and symptoms of myositis. For suspected myositis, monitor serial aldolase and creatine kinase and consider diagnostic workup according to current clinical guidelines. Patients should be managed with toripalimab treatment modifications (see section 4.2) and corticosteroids, as clinically indicated (see instructions for corticosteroid treatment in section 4.4 above). Other immune-related adverse reactions Given the mechanism of action of toripalimab, other potential immune-related adverse reactions may occur, including potentially serious events (e.g., encephalitis, demyelinating neuropathy [including Guillain Barré syndrome] myasthenic syndrome, sarcoidosis, vasculitis, rhabdomyolysis). Clinically significant immune-related adverse reactions reported in less than 1 % of patients treated with toripalimab in the clinical studies include pancreatitis, iritis, uveitis, immune-related inflammatory arthritis, and immune-related cystitis. Patients should be monitored for signs and symptoms of immune-related adverse reactions and managed with toripalimab treatment modifications (see section 4.2) and corticosteroids, as clinically indicated (see instructions for corticosteroid treatment in section 4.4 above). Transplant-related adverse reactions Solid organ transplant rejection has been reported in the post-marketing setting in patients treated with PD-1 inhibitors. Treatment with toripalimab may increase the risk of rejection in solid organ transplant recipients. The benefit of treatment with toripalimab versus the risk of possible organ rejection should be considered in these patients. Fatal and other serious complications can occur in patients who received an allogeneic haematopoietic 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 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 the 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. Infusion-related reactions Toripalimab can cause severe and potentially life-threatening infusion-related reactions (see section 4.8). Patients should be monitored for signs and symptoms of infusion-related reactions. Patients should be managed with toripalimab treatment modifications and supportive care, as clinically indicated (see section 4.2). For patients with infusion related reactions, pre-medications with antipyretics and antihistamines to mitigate the risk of subsequent infusion reactions may be considered. Patients excluded from clinical studies Patients with active infections (active tuberculosis or hepatitis B or C or HIV infection), an immunocompromised state (systemic corticosteroids > 10 mg daily prednisone equivalents within 2 weeks of randomisation), active, systemic autoimmune diseases (except for controlled hypothyroidism or diabetes mellitus), active or untreated central nervous system metastases, eastern cooperative oncology group (ECOG) performance status (PS) = 2, or a history of interstitial lung disease were not eligible for enrolment in clinical studies of toripalimab. There is limited information in patients with severe renal or moderate to severe hepatic impairment (see section 5.2). In the absence of data, toripalimab should be used with caution in these populations after careful evaluation of the balance of benefits and risks for the patient. Excipient with known effect This medicine contains less than 1 mmol sodium (23 mg) per dosage unit, that is to say essentially ‘sodium-free’.

No formal

Women of childbearing potential/Contraception Women of childbearing potential should use effective contraception during treatment with toripalimab and for at least 4 months after the last dose of toripalimab. Pregnancy There are no data on the use of toripalimab in pregnant women. Animal studies have not been conducted with toripalimab; however, animal studies have demonstrated that inhibition of the PD-1/PD-L1 pathway can lead to increased risk of immune-related rejection of the developing foetus and result in foetal death (see section 5.3). Human immunoglobulin G4 (IgG4) is known to cross the placental barrier; therefore, toripalimab can potentially be transmitted from the mother to the developing foetus. Toripalimab should not be used during pregnancy or in women of childbearing potential not using effective contraception unless the clinical benefit outweighs the potential risk. Breast-feeding It is unknown whether toripalimab is secreted in human milk. It is known that antibodies (including IgG4) are secreted in human milk; a risk to the breast-feeding newborn/infant cannot be excluded. A decision must be made whether to discontinue breast-feeding or to discontinue/abstain from toripalimab therapy taking into account the benefit of breast feeding for the child and the benefit of therapy for the woman. If a woman chooses to be treated with toripalimab, she should be instructed not to breast-feed while receiving toripalimab and for at least 4 months after the last dose of toripalimab. Fertility Studies to evaluate the effect of toripalimab on fertility have not been performed (see section 5.3).

Toripalimab has minor influence on the ability to drive and use machines. In some patients, dizziness and fatigue have been reported following administration of toripalimab (see section 4.8).

Summary of the safety profile Toripalimab in combination with platinum containing chemotherapy (see section 4.2) The safety of toripalimab in combination with platinum containing chemotherapy has been evaluated in 403 patients with NPC or oesophageal squamous cell carcinoma (OSCC) receiving 240 mg toripalimab every 3 weeks in JUPITER-02 or JUPITER-06. The median duration of treatment in these patients was 6.5 months (range 1 day-2.1 years). The frequencies included below and in Table 2 are based on all reported adverse drug reactions, regardless of the investigator assessment of causality. In this patient population, the most frequent adverse reactions were anaemia (44.9%), leukopenia (41.7%), neutropenia (39.0%), thrombocytopenia (30.3%), nausea (29.8%), vomiting (27.3%), decreased appetite (23.8%), rash (23.8%), fatigue (23.6%), liver function test abnormal (22.3%), hypothyroidism (18.4%), constipation (16.6%), neuropathy (15.1%), colitis (14.1), pyrexia (13.6%), cough (11.4%), pruritus (11.4%), creatinine renal clearance decreased (11.2%), and hyponatraemia (10.2%). Incidences of grades 3-5 adverse reactions in patients with NPC were 81.5% for toripalimab combination therapy and 83.9% for chemotherapy alone and in patients with OSCC were 24.9% for toripalimab combination therapy and 13.6% for chemotherapy alone. Tabulated list of adverse reactions Adverse reactions observed in clinical studies of toripalimab as monotherapy or in combination with chemotherapy are listed in Table 2. Adverse reactions are presented by system organ class and by frequency. Frequencies are defined as: very common (= 1/10); common (= 1/100 to < 1/10); uncommon (= 1/1 000 to < 1/100); rare (= 1/10 000 to < 1/1 000); very rare (< 1/10 000); not known (cannot be estimated from the available data). Within each frequency grouping, adverse reactions are presented in the order of decreasing seriousness. Table 2 includes only treatment related adverse drug reactions. The adverse reaction frequencies from clinical studies are based on all-cause adverse event frequencies, where a proportion of the events for an adverse reaction may have other causes than the medicinal product such as the disease, other medicines or unrelated causes. Adverse reactions reported in clinical studies are listed by system organ class and by frequency. The safety data is based on 1 514 patients exposed to toripalimab (of which 1 100 patients were exposed to toripalimab monotherapy and 514 patients in combination with chemotherapy) with a mean (range 0.03 months to 35.9 months) duration of exposure to toripalimab of 7.0 months and a median duration of exposure of 3.7 months (interquartile range 8.7 months) in 15 Phase 1, 2 or 3 clinical studies. See Section 5.1 for information on the demographics and baseline characteristics of participants in the main clinical studies. When toripalimab is administered in combination with chemotherapy, refer to the SmPCs for the respective combination therapy components prior to initiation of treatment.

Immune-related skin adverse reactions Immune-related skin adverse reactions occurred in 9.4% (38/403) of patients receiving toripalimab in JUPITER-02 and JUPITER-06, including 12 Grade 3 (3.0%) and 8 Grade 2 (2.0%) adverse reactions. The median time to onset of immune-related skin adverse reactions was 1.0 month (range 0.1 to 23.1 months). The median duration was 1.2 months (range 0.1 to 13.1 months). Systemic corticosteroids were required in 18.4% (7/38) of the patients with immune-related skin adverse reactions. Immune-related skin adverse reactions led to permanent discontinuation or interruption of toripalimab in 1.5% (6) of patients. Immune-related skin adverse reactions resolved in 73.7% (28/38) of these patients. Immune-related myocarditis Immune-related myocarditis occurred in 0.7% (3/403) of patients receiving toripalimab in JUPITER-02 and JUPITER-06, including 2 (0.5%) Grade 4 and 1 (0.2%) Grade 3adverse reactions. The median time to onset of immune-related myocarditis was 1.7 months (range 1.4 to 4.1 months). The median duration was 1.3 months (range 1.0 to 1.6 months).

Infusion related reactions Of the 403 patients who received toripalimab in combination with platinum containing chemotherapy in JUPITER-02 or JUPITER-06, infusion-related reactions occurred in 11 patients (2.7%), including Grade 4 (0.2%), Grade 3 (0.2%) and Grade 2 (0.5%) adverse reactions. Overall, infusion related reactions occurred in 28 (1.8%) of 1514 patients treated with toripalimab, including Grade 4 (0.07%) and Grade 3 (0.13%) reactions. Infusion-related reaction led to permanent discontinuation of toripalimab in 3 (0.2%) patients. Common symptoms of infusion-related reaction include fever, chills, rash, pruritus, nausea and hypotension. Immunogenicity As with all therapeutic proteins, there is potential for immunogenicity. In patients who received toripalimab, treatment-emergent antibodies to toripalimab were detected in 8.7% (128/1479) of the evaluable patients tested. There was no evidence of any clinically relevant effect of anti-toripalimab antibody development on its pharmacokinetics. Across all studies, the median time to onset of ADA was 46 days (range to 14 to 506 days). There are insufficient numbers of patients to adequately assess the effect of ADA on efficacy. Elderly Of the 403 patients treated with toripalimab in combination with platinum-based chemotherapy in clinical studies, 73.2% (295/403) were less than 65 years and 26.8% (108/403) were 65 years or older. No overall differences in safety were observed between patients = 65 years of age and younger patients receiving toripalimab.

Pharmacotherapeutic group: Antineoplastic agents, ATC code: L01FF13 Mechanism of action Toripalimab is a humanised IgG4 monoclonal antibody that binds to the PD-1 receptor and blocks its

Toripalimab pharmacokinetics were characterised using population PK analyses that included data from 574 patients across 5 clinical studies with various solid tumours who received fixed (80 to 480 mg Q2W or Q3W) or weight-based (range: 1 to 10 mg/kg Q2W) dosing, including 92 patients with NPC and 236 patients with OSCC who received toripalimab at doses of 240 mg every 3 weeks in JUPITER-02 and JUPITER-06, respectively. Toripalimab pharmacokinetic parameters are presented as geometric mean (coefficient of variation [CV]%) unless otherwise noted. Absorption Toripalimab is administered via the intravenous route; therefore, it is completely bioavailable. Distribution Toripalimab is primarily distributed in the plasma with a geometric mean volume of distribution at steady state of approximately 3.8 L (CV=27.4%). Biotransformation Dedicated metabolism studies were not performed. As a monoclonal antibody, toripalimab is expected to be metabolized into small peptides, amino acids, and small carbohydrates by catabolic pathways or by receptor-mediated endocytosis. The degradation products are eliminated by renal excretion or returned to the nutrient pool without biological effects. Elimination Toripalimab pharmacokinetics followed a 2-compartment model with time-varying clearance (CL). The mean CL was 12.01 mL/h (CV = 27%) after the first dose and 8.49 mL/h (CV = 24.4%) at steady state. The geometric mean value (CV%) for the terminal half-life is 14 days (32.5%) at steady-state with toripalimab administered at 240 mg Q3W. Linearity/non-linearity Exposure to toripalimab, as expressed by peak concentrations (Cmax), increased dose proportionally over the dose range of 80 to 480 mg Q2W. The geometric mean trough concentrations (Cmin) at steady state were estimated in the population PK model to be 26.3 µg/mL in patients receiving 240 mg every 3 weeks. The mean accumulation of Cmin at steady state is 2.7-fold compared to the Cmin after the first dose. Pharmacokinetic/pharmacodynamic relationship(s) Toripalimab exposure-response relationships for efficacy are essentially flat over the range of exposures achieved for nasopharyngeal carcinoma in JUPITER-02 and for OSCC in JUPITER-06. The toripalimab exposure-response relationships for safety showed negative (inverse) relationships over the range of exposures achieved; however, this is likely an artifact reflecting toripalimab accumulation. Anticipated full receptor occupancy of PD-1 in immune cells was achieved at exposures below mean trough concentrations after the first dose and steady state at dose of 240 mg Q3W. Special populations No clinically significant differences in the pharmacokinetics of toripalimab were observed based on age (range: 19 to 85 years), body weight (range: 39 to 164 kg), sex, concomitant chemotherapy, mild or moderate renal impairment, mild hepatic impairment, tumour burden and primary cancer. Renal impairment The effect of renal impairment based on the estimated creatinine clearance on the clearance and volume of distribution of toripalimab were evaluated using population pharmacokinetic analyses. No differences in clearance or volume of distribution were found between patients with mild (CLcr 60 to 89 mL/min; n=483) or moderate (CLcr 30 to 59 mL/min; n=114) renal impairment and patients with normal renal function. The effect of severe (CLcr 15 to 29 mL/min) renal impairment on the pharmacokinetics of toripalimab has not been studied. Hepatic impairment The effects of hepatic impairment using the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) grading system for hepatic dysfunction on the clearance and volume of distribution of toripalimab were evaluated using population pharmacokinetic analyses. No differences in clearance or volume of distribution were found between patients with mild (Grade 1, n=166) hepatic impairment (total bilirubin up to 1.5 times the upper limit of normal (ULN) or total bilirubin within normal limits and aspartate transaminase (AST) or alanine transaminase (ALT) > 1 and = 3 ULN) compared to patients with normal liver function. There was a limited number of patients with moderate (Grade 2, n=1; total bilirubin > 1.5 to 3 times ULN and any AST) hepatic impairment and no patients with severe (Grade 3; total bilirubin > 3 times ULN and any AST) hepatic impairment enrolled in clinical studies of toripalimab.

No studies have been performed to test the potential of toripalimab for carcinogenicity or genotoxicity. Animal reproduction studies have not been conducted with toripalimab to evaluate its effect on reproduction and foetal development. A central function of the PD-1/PD-L1 pathway is to preserve pregnancy by maintaining maternal immune tolerance to the foetus. In murine models of pregnancy, blockade of PD-L1 signalling has been shown to disrupt tolerance to the foetus and to result in an increase in foetal loss. Fertility studies have not been conducted with toripalimab. In 4-week and 26-week repeat-dose toxicology studies in cynomolgus monkeys, there were no adverse or notable effects in the male and female reproductive organs. However, those animals were unlikely sexually mature.
