⏳ Availability & biosimilar status
Biologics have no small-molecule generics; biosimilar competition is tracked in the FDA Purple Book.
Why the date isn’t exact: Biosimilar timing can change because patents may be challenged, settled, licensed, added or removed, and litigation can move the real date earlier or later.
🛈 What do these terms mean?
- Biologic patent
- A patent the reference product’s maker has publicly listed. A biosimilar generally can’t launch until these expire — unless they’re invalidated or resolved in a settlement.
- Reference-product exclusivity
- A flat 12 years of FDA market protection from the biologic’s first licensure (the BPCIA). No biosimilar can be licensed before it ends, regardless of patents.
- Interchangeable exclusivity
- The first interchangeable biosimilar can earn a period as the only interchangeable version (pharmacists can substitute it without the prescriber).
- Earliest biosimilar (LOE)
- The latest of all the dates above — the soonest a biosimilar can realistically reach the market. Litigation and settlements can move it earlier.
Biologics have no small-molecule “generics” — competition comes from FDA-licensed biosimilars, tracked in the FDA Purple Book.
| Code | What it grants | Expires |

⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS Immune-Mediated Adverse Reactions ( 5.1 ) Immune-mediated adverse reactions, which may be severe or fatal, can occur in any organ system or tissue, including the following: immune-mediated pneumonitis, immune-mediated colitis, immune-mediated hepatitis, immune-mediated endocrinopathies, immune-mediated nephritis with renal dysfunction, immune-mediated dermatologic adverse reactions, and solid organ transplant rejection. Monitor for early identification and management. Evaluate liver enzymes, creatinine, and thyroid function at baseline and periodically during treatment.
( 5.1 ) Withhold or permanently discontinue based on severity and type of reaction. ( 5.1 ) Infusion-related reactions : Interrupt, slow the rate of infusion, or permanently discontinue LOQTORZI based on the severity of reaction. ( 5.2 ) Complications of allogeneic HSCT : Fatal and other serious complications can occur in patients who receive allogeneic HSCT before or after being treated with a PD-1/PD-L1 blocking antibody.
( 5.3 ) Embryo-fetal toxicity : Can cause fetal harm. Advise females of reproductive potential of the potential risk to a fetus and to use effective method of contraception. ( 5.4 , 8.1 , 8.3 )
5.1Severe and Fatal Immune-Mediated Adverse Reactions LOQTORZI is a monoclonal antibody that belongs to a class of drugs that bind to either the programmed death receptor-1 (PD-1) or PD-ligand 1 (PD-L1), blocking the PD-1/PD-L1 pathway, thereby removing inhibition of the immune response, potentially breaking peripheral tolerance and inducing immune-mediated adverse reactions. Important immune-mediated adverse reactions listed under WARNINGS AND PRECAUTIONS may not include all possible severe and fatal immune-mediated reactions.
Immune-mediated adverse reactions, which may be severe or fatal, can occur in any organ system or tissue and can affect more than one body system simultaneously. Immune-mediated adverse reactions can occur at any time after starting PD-1/PD-L1 blocking antibody. While immune-mediated adverse reactions usually manifest during treatment with PD-1/PD-L1 blocking antibodies, immune-mediated adverse reactions can also manifest after discontinuation of PD-1/PD-L1 blocking antibodies.
Early identification and management of immune-mediated adverse reactions are essential to ensure safe use of PD-1/PD-L1 blocking antibodies. Monitor closely for symptoms and signs that may be clinical manifestations of underlying immune-mediated adverse reactions. 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 depending on severity [see Dosage and Administration (2.2) ] .
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.
Toxicity management guidelines for adverse reactions that do not necessarily require systemic steroids (e.g., endocrinopathies and dermatologic reactions) are discussed below. Immune-Mediated Pneumonitis LOQTORZI in Combination with Cisplatin and Gemcitabine LOQTORZI in combination with cisplatin and gemcitabine can cause immune-mediated pneumonitis. In patients treated with other PD-1/PD-L1 blocking antibodies, the incidence of pneumonitis is higher in patients who have received prior thoracic radiation.
Immune-mediated pneumonitis occurred in 2.1% (3/146) of patients receiving…
🤒 Adverse Reactions ▾
6 ADVERSE REACTIONS The following clinically significant adverse reactions are described elsewhere in the labeling: Severe and fatal immune-mediated adverse reactions [see Warnings and Precautions (5.1) ] Infusion-related reactions [see Warnings and Precautions (5.2) ] Complications of Allogeneic HSCT [see Warnings and Precautions (5.3) ] LOQTORZI in Combination with Cisplatin and Gemcitabine The most common adverse reactions (≥ 20%) are nausea, vomiting, decreased appetite, constipation, hypothyroidism, rash, pyrexia, diarrhea, peripheral neuropathy, cough, musculoskeletal pain, upper respiratory infection, insomnia, dizziness, and malaise.
( 6.1 ) LOQTORZI as a Single Agent The most common adverse reactions (≥ 20%) are fatigue, hypothyroidism and musculoskeletal pain. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Coherus Oncology, Inc. at 1-800-483-3692 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.
6.1Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The data described in the WARNINGS AND PRECAUTIONS section reflect exposure to LOQTORZI at a dose of 240 mg every 3 weeks in combination with up to 6 cycles of cisplatin and gemcitabine, followed by LOQTORZI 240 mg IV every 3 weeks, in 146 patients with NPC enrolled in a randomized, double-blind, placebo-controlled trial (JUPITER-02).
Among the 146 patients, 73% were exposed to LOQTORZI for 6 months or more and 54% were exposed for 12 months or more. The most common adverse reactions (≥ 20%) were: nausea (71%), vomiting (68%), decreased appetite (55%), constipation (39%), hypothyroidism (38%), rash (36%), pyrexia (32%), diarrhea (31%), peripheral neuropathy (30%), cough (26%), musculoskeletal pain (25%), upper respiratory infection (23%), insomnia (23%), dizziness (21%), and malaise (21%). The most common Grade 3 or 4 laboratory abnormalities (≥2%) were: decreased neutrophils (58%), decreased lymphocytes (57%), decreased hemoglobin (50%) decreased platelets (33%), decreased potassium (10%), decreased sodium (9%), increased alanine aminotransferase (6%) increased or decreased magnesium (4.2% each), decreased calcium (3.5%), increased aspartate aminotransferase (2.7%), and bilirubin increased (2.1%).
The data described in the WARNINGS AND PRECAUTIONS section also reflects exposure to LOQTORZI as a single agent at a dose of 3 mg/kg IV every 2 weeks in 851 patients enrolled in 12 trials: one randomized, active-controlled trial and 11 open-label, non-randomized trials. The tumor types included nasopharyngeal carcinoma (n=193) or other types of tumors (n=658). Among the 851 patients treated with LOQTORZI as a single agent, 35% were exposed for 6 months or more and 20% were exposed for 12 months or more.
In this pooled safety population, the most common (≥20%) adverse reactions were: fatigue (22%), hypothyroidism (20%), and musculoskeletal pain (20%). The most common Grade 3 or 4 laboratory abnormalities (≥2%), were decreased sodium (9%), decreased lymphocytes (8%), decreased hemoglobin (7%), decreased fibrinogen (4.5%), increased lipase (4.0%), increased amylase (2.9%), decreased phosphate (2.8%), increased aspartate aminotransferase (2.6%), increased glucose (2.5%), and increased triglycerides (2.1%). First-line Treatment of Metastatic or Recurrent, Locally Advanced Nasopharyngeal Carcinoma (NPC) The safety of LOQTORZI in combination with cisplatin and gemcitabine was evaluated in JUPITER-02 [see Clinical Studies (14) ] .
Key eligibility criteria were recurrent locally advanced or metastatic nasopharyngeal carcinoma (NPC) not previously treated with systemic chemotherapy for recurrent or metastatic disease. Patients with recurrent NPC after treatment with curative intent were required to have an interval of at least 6 months between…
👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS Lactation : Advise not to breastfeed. ( 8.2 )
8.1Pregnancy Risk Summary Based on its mechanism of action, LOQTORZI can cause fetal harm when administered to a pregnant woman [ see Clinical Pharmacology (12.1) ] . There are no available data on the use of LOQTORZI in pregnant women. 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 and result in fetal death (see Data ) .
Human IgG4 immunoglobulins (IgG4) are known to cross the placenta; therefore, LOQTORZI can potentially be transmitted from the mother to the developing fetus. Advise women of the potential risk to a fetus. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.
Data Animal Data Animal reproduction studies have not been conducted with LOQTORZI to evaluate its effect on reproduction and fetal development. A central function of the PD-1/PD-L1 pathway is to preserve pregnancy by maintaining maternal immune tolerance to the fetus. In murine models of pregnancy, blockade of PD-L1 signaling has been shown to disrupt tolerance to the fetus and to result in an increase in fetal loss; therefore, potential risks of administering LOQTORZI during pregnancy could include increased rates of abortion or stillbirth.
As reported in the literature, there were no malformations related to the blockade of PD-1/PD-L1 signaling in the offspring of these animals; however, immune-mediated disorders occurred in PD-1 and PD-L1 knockout mice. Based on its mechanism of action, fetal exposure to toripalimab-tpzi may increase the risk of developing immune-mediated disorders or altering the normal immune response.
8.2Lactation Risk Summary There are no data on the presence of toripalimab-tpzi in human milk or 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.
8.3Females and Males of Reproductive Potential LOQTORZI can cause fetal harm when administered to a pregnant woman [see Use in Specific Populations (8.1) ]. Pregnancy Testing Verify the pregnancy status of females of reproductive potential prior to initiating LOQTORZI [see Use in Specific Populations (8.1) ] . Contraception Females Advise females of reproductive potential to use effective contraception during treatment with LOQTORZI and for 4 months after the last dose.
8.4Pediatric Use The safety and effectiveness of LOQTORZI have not been established in pediatric patients [see Indications and Usage (1) ].
8.5Geriatric Use Of the 146 patients with NPC who were treated with LOQTORZI in combination with cisplatin and gemcitabine 7 (4.8%) were 65 years or older; there were no patients 75 years and older. Clinical studies of LOQTORZI in combination with cisplatin and gemcitabine did not include a sufficient number of patients aged 65 years and over with NPC to determine whether they respond differently from younger patients. Of the 851 patients with tumor types including nasopharyngeal carcinoma or other types of tumors from the safety pool treated with LOQTORZI as a single agent, 171 (20%) patients were 65 years or older and 13 (1.5%) patients were 75 years and older.
No overall differences in safety were observed between elderly patients and younger patients [see Adverse Reactions (6.1) ]. Of the 190 patients with NPC treated with LOQTORZI as single agent, 10 (5%) patients were 65 years or older; there were no patients 75 years and older.

🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action Binding of the PD-1 ligands, PD-L1 and PD-L2, to the PD-1 receptor found on T cells, inhibits T cell proliferation and cytokine production. Upregulation of PD-1 ligands occurs in some tumors and signaling through this pathway can contribute to inhibition of active T-cell immune surveillance of tumors. Toripalimab-tpzi is a humanized IgG4 monoclonal antibody that binds to the PD-1 receptor and blocks its interaction with PD-L1 and PD-L2, releasing PD-1 pathway-mediated inhibition of the immune response, including the anti-tumor immune response.
In syngeneic mouse tumor models, blocking PD-1 activity resulted in decreased tumor growth.
12.2Pharmacodynamics The toripalimab-tpzi exposure-response relationships and time course of pharmacodynamic response are not fully characterized.
12.3Pharmacokinetics Toripalimab-tpzi pharmacokinetic parameters are presented as geometric mean (coefficient of variation [CV]%) unless otherwise noted. Toripalimab-tpzi concentrations increased in non-linearly over the dose range of 0.3 to 10 mg/kg every two weeks (0.1 to 3.3 times the approved recommended 3 mg/kg dosage in a 64 kg patient). Steady state was reached by Week 7.
The mean accumulation ratio was approximately 1.4 for maximum concentration (C max ) and 1.9 for area under the serum concentration curve (AUC) following multiple doses at the approved recommended dosages of 240 mg Q3W in combination with cisplatin and gemcitabine and 3 mg/kg Q2W as monotherapy. Distribution The mean volume of distribution at steady state (V ss ) of toripalimab-tpzi was
3.7L (27%). Elimination The mean clearance (CL) was 14.9 mL/h (31%) after the first dose and 9.5 mL/h (36%) at steady state. The mean terminal half-life (t 1/2 ) (± standard deviation) was 10 ± 1.5 days after the first dose and 18 ± 9.4 days at steady state.
Metabolism Toripalimab-tpzi is expected to be metabolized into small peptides by catabolic pathways. Specific Populations No clinically significant differences in the pharmacokinetics were observed based on age (21 to 85 years), body weight (32 to 164 kg), sex, race (White and Asian), concomitant chemotherapy, mild renal impairment (creatinine clearance [CLcr] 60 to 89 mL/min), mild hepatic impairment (total bilirubin > 1 to 1.5 times ULN with any AST or total bilirubin ≤ ULN with AST > ULN), tumor burden and primary cancer.
The effect of moderate (total bilirubin >1.5 to 3 times ULN and any AST) or severe (total bilirubin > 3 times ULN and any AST) hepatic impairment or of moderate (CLcr 30 to 59 mL/min) or severe (CLcr 15 to 29 mL/min ) renal impairment on the pharmacokinetics of toripalimab-tpzi has not been studied.
12.6Immunogenicity The observed incidence of anti-drug antibodies (ADA) is highly dependent on the sensitivity and specificity of the assay. Differences in assay methods preclude meaningful comparisons of the incidence of ADA in the studies described below with the incidence of ADA in other studies, including those of LOQTORZI or of other toripalimab products. Of the 146 evaluable patients in JUPITER-02 with nasopharyngeal cancer who received LOQTORZI 240 mg every 3 weeks for a median duration of 15.1 months, in combination with gemcitabine and cisplatin, 3.4% tested positive for treatment-emergent ADA.
Of the 190 evaluable patients in study POLARIS-02 with nasopharyngeal cancer who received LOQTORZI 3 mg/kg every 2 weeks for a median duration of 3.3 months, 3.7% of patients developed treatment-emergent ADA. Neutralizing antibodies have not been tested. Due to the low incidence of ADA, the effect of these antibodies on the pharmacokinetics, pharmacodynamics, safety, or effectiveness of LOQTORZI is unknown.
