⏳ 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 |

2.1Assessments Prior to First Dose of OCREVUS Hepatitis B Virus Screening Prior to initiating OCREVUS, perform Hepatitis B virus (HBV) screening. OCREVUS is contraindicated in patients with active HBV confirmed by positive results for HBsAg and anti-HBV tests. For patients who are negative for surface antigen [HBsAg] and positive for HB core antibody [HBcAb+] or are carriers of HBV [HBsAg+], consult liver disease experts before starting and during treatment [see Warnings and Precautions (5.2) ] .
Serum Immunoglobulins Prior to initiating OCREVUS, perform testing for quantitative serum immunoglobulins [see Warnings and Precautions (5.4) ] . For patients with low serum immunoglobulins, consult immunology experts before initiating treatment with OCREVUS. Vaccinations Because vaccination with live-attenuated or live vaccines is not recommended during treatment and after discontinuation until B-cell repletion, administer all age-appropriate immunizations according to immunization guidelines at least 4 weeks prior to initiation of OCREVUS for live or live-attenuated vaccines and, whenever possible, at least 2 weeks prior to initiation of OCREVUS for non-live vaccines [see Warnings and Precautions (5.2) and Clinical Pharmacology (12.2) ] .
Liver Function Tests Prior to initiating OCREVUS, obtain serum aminotransferases (alanine aminotransferase [ALT] and aspartate aminotransferase [AST]), alkaline phosphatase, and bilirubin levels [see Warnings and Precautions (5.7) ] .
2.2Preparation Before Every Infusion Infection Assessment Prior to every infusion of OCREVUS, determine whether there is an active infection. In case of active infection, delay infusion of OCREVUS until the infection resolves [see Warnings and Precautions (5.2) ]. Recommended Premedication To reduce the frequency and severity of infusion reactions, administer the following premedications [see Warnings and Precautions (5.1) ] : Methylprednisolone (or an equivalent corticosteroid) by intravenous infusion to be completed approximately 30 minutes prior to each OCREVUS infusion, as follows: Adults and pediatric patients who weigh 40 kg or more: 100 mg Pediatric patients who weigh less than 40 kg: 2 mg/kg An antihistamine (e.g., diphenhydramine) 30 to 60 minutes prior to each OCREVUS infusion.
An antipyretic (e.g., acetaminophen) may also be considered. Administer the antipyretic 30 minutes to 60 minutes prior to OCREVUS infusion.
2.3Recommended Dosage and Dose Administration Administer OCREVUS under the close supervision of an experienced healthcare professional with access to appropriate medical support to manage severe reactions such as serious infusion reactions. Observe the patient for at least one hour after the completion of the infusion [see Warnings and Precautions (5.1) ] . OCREVUS is administered as an intravenous infusion.
The initial dose is split into two equal infusions administered two weeks apart. Subsequent…

⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS Infusion Reactions: Management recommendations for infusion reactions depend on the type and severity of the reaction. Permanently discontinue OCREVUS if a life-threatening or disabling infusion reaction occurs ( 2.3 , 5.1 ) Infections: Serious, including life-threatening and fatal infections, have occurred. Delay OCREVUS administration in patients with an active infection until the infection is resolved.
Vaccination with live-attenuated or live vaccines is not recommended during treatment with OCREVUS and after discontinuation, until B-cell repletion ( 5.2 ) Progressive Multifocal Leukoencephalopathy (PML): Withhold OCREVUS at the first sign or symptom suggestive of PML ( 5.3 ) Reduction in Immunoglobulins: Monitor the level of immunoglobulins at the beginning of treatment. Monitor during and after discontinuation of treatment with OCREVUS, until B-cell repletion, and especially when recurrent serious infections are suspected.
Consider discontinuing OCREVUS in patients with serious opportunistic or recurrent serious infections, and if prolonged hypogammaglobulinemia requires treatment with intravenous immunoglobulins ( 2.1 , 5.4 ) Malignancies: An increased risk of malignancy, including breast cancer, may exist with OCREVUS ( 5.5 ) Immune-Mediated Colitis: Immune-mediated colitis has been reported in the postmarketing setting. Monitor patients for new or persistent diarrhea or other gastrointestinal symptoms, and evaluate promptly if colitis is suspected ( 5.6 ) Liver Injury: Clinically significant liver injury has occurred.
Obtain serum aminotransferases, alkaline phosphatase, and bilirubin levels before initiating OCREVUS, and during treatment as clinically indicated. Discontinue OCREVUS in patients with evidence of liver injury in the absence of an alternative etiology ( 5.7 ).
5.1Infusion Reactions OCREVUS can cause infusion reactions, which can include pruritus, rash, urticaria, erythema, bronchospasm, throat irritation, oropharyngeal pain, dyspnea, pharyngeal or laryngeal edema, flushing, hypotension, pyrexia, fatigue, headache, dizziness, nausea, tachycardia, and anaphylaxis. These reactions are more commonly reported with the first infusion. In multiple sclerosis (MS) clinical trials, all adult and pediatric patients who were treated with OCREVUS received premedication with methylprednisolone (or an equivalent steroid), and may have also received an antihistamine (all pediatric patients) and/or an analgesic/antipyretic to reduce the risk of infusion reactions prior to each infusion.
In adults, the incidence of infusion reactions in patients treated with OCREVUS was 34 to 40%. There were no fatal infusion reactions, but 0.3% of patients with MS who were treated with OCREVUS experienced infusion reactions that were serious, some requiring hospitalization. In pediatric patients, the incidence of infusion reactions in patients treated with OCREVUS was 48%, compared with an incidence of 24% in patients who received placebo infusion (fingolimod-treated patients).
There were no fatal infusion reactions, but one pediatric patient (1.1%) treated with OCREVUS experienced an infusion reaction that was serious because it required hospitalization [see Adverse Reactions (6.1) ] . Observe patients treated with OCREVUS for infusion reactions during the infusion and for at least one hour after completion of the infusion. Inform patients that infusion reactions can occur up to 24 hours after the infusion.
Reducing the Risk of Infusion Reactions and Managing Infusion Reactions Administer pre-medication (e.g., methylprednisolone or an equivalent corticosteroid, and an antihistamine) to reduce the frequency and severity of infusion reactions. The addition of an antipyretic (e.g., acetaminophen) may also be considered [see Dosage and Administration (2.2) ]. Management recommendations for infusion reactions depend on the type and severity of the reaction [see Dosage and Administration (2.5) ].

6 ADVERSE REACTIONS The following serious adverse reactions are discussed elsewhere in the labeling: Infusion Reactions [see Warnings and Precautions (5.1) ] Infections [see Warnings and Precautions (5.2) ] Progressive Multifocal Leukoencephalopathy [see Warnings and Precautions (5.3) ] Reduction in Immunoglobulins [see Warnings and Precautions (5.4) ] Malignancies [see Warnings and Precautions (5.5) ] Immune-Mediated Colitis [see Warnings and Precautions (5.6) ] Liver Injury [see Warnings and Precautions (5.7) ] The most common adverse reactions were: RMS (incidence ≥10% and > REBIF ® ): upper respiratory tract infections and infusion reactions ( 6.1 ) PPMS (incidence ≥10% and > placebo): upper respiratory tract infections, infusion reactions, skin infections, and lower respiratory tract infections ( 6.1 ) RRMS in pediatric patients 10 years of age and older: Adverse reactions were consistent with those observed in adults with RMS ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Genentech at 1-888-835-2555 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 reactions 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 clinical practice. Adults The safety of OCREVUS has been evaluated in 1311 adult patients across MS clinical studies, which included 825 patients in active-controlled clinical trials in patients with relapsing forms of MS (RMS) and 486 patients in a placebo-controlled study in patients with primary progressive MS (PPMS).
Adverse Reactions in Adult Patients with Relapsing Forms of MS In active-controlled clinical trials (Study 1 and Study 2), 825 patients with RMS received OCREVUS 600 mg intravenously every 24 weeks (initial treatment was given as two separate 300 mg infusions at Weeks 0 and 2) [see Clinical Studies (14.1) ]. The overall exposure in the 96-week controlled treatment periods was 1448 patient-years. The most common adverse reactions in RMS trials (incidence ≥ 10%) were upper respiratory tract infections and infusion reactions.
Table 4 summarizes the adverse reactions that occurred in RMS trials (Study 1 and Study 2). Table 4 Adverse Reactions in Adult Patients with RMS with an Incidence of at least 5% for OCREVUS and Higher than REBIF Adverse Reactions Studies 1 and 2 OCREVUS 600 mg IV Every 24 Weeks The first dose was given as two separate 300 mg infusions at Weeks 0 and 2.

🔄 Drug Interactions ▾
7 DRUG INTERACTIONS
7.1Immunosuppressive or Immune-Modulating Therapies The concomitant use of OCREVUS and other immune-modulating or immunosuppressive therapies, including immunosuppressant doses of corticosteroids, is expected to increase the risk of immunosuppression. Consider the risk of additive immune system effects when coadministering immunosuppressive therapies with OCREVUS. When switching from drugs with prolonged immune effects, such as daclizumab, fingolimod, natalizumab, teriflunomide, or mitoxantrone, consider the duration and mode of action of these drugs because of additive immunosuppressive effects when initiating OCREVUS [see Warnings and Precautions (5.2) ].
7.2Vaccinations A Phase 3b randomized, open-label study examined the concomitant use of OCREVUS and several non-live vaccines in adults 18-55 years of age with relapsing forms of MS (68 subjects undergoing treatment with OCREVUS at the time of vaccination and 34 subjects not undergoing treatment with OCREVUS at the time of vaccination). Concomitant exposure to OCREVUS attenuated antibody responses to tetanus toxoid-containing vaccine, pneumococcal polysaccharide, pneumococcal conjugate vaccines, and seasonal inactivated influenza vaccines.
The impact of the observed attenuation on vaccine effectiveness in this patient population is unknown. The safety and effectiveness of live or live-attenuated vaccines administered concomitantly with OCREVUS have not been assessed [see Warnings and Precautions (5.2) ] .
👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS Pregnancy: Based on animal data, may cause fetal harm ( 8.1 )
8.1Pregnancy Risk Summary OCREVUS is a humanized monoclonal antibody of an immunoglobulin G1 subtype and immunoglobulins are known to cross the placental barrier. There are no adequate data on the developmental risk associated with use of OCREVUS in pregnant women. However, transient peripheral B-cell depletion and lymphocytopenia have been reported in infants born to mothers exposed to other anti-CD20 antibodies during pregnancy.
B-cell levels in infants following maternal exposure to OCREVUS have not been studied in clinical trials. The potential duration of B-cell depletion in such infants, and the impact of B-cell depletion on vaccine safety and effectiveness, is unknown [see Warnings and Precautions (5.2) ] . Following administration of ocrelizumab to pregnant monkeys at doses similar to or greater than those used clinically, increased perinatal mortality, depletion of B-cell populations, renal, bone marrow, and testicular toxicity were observed in the offspring in the absence of maternal toxicity [see Data ] .
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. The background risk of major birth defects and miscarriage for the indicated population is unknown. Data Animal Data Following intravenous administration of OCREVUS to monkeys during organogenesis (loading doses of 15 or 75 mg/kg on gestation days 20, 21, and 22, followed by weekly doses of 20 or 100 mg/kg), depletion of B-lymphocytes in lymphoid tissue (spleen and lymph nodes) was observed in fetuses at both doses.
Intravenous administration of OCREVUS (three daily loading doses of 15 or 75 mg/kg, followed by weekly doses of 20 or 100 mg/kg) to pregnant monkeys throughout the period of organogenesis and continuing through the neonatal period resulted in perinatal deaths (some associated with bacterial infections), renal toxicity (glomerulopathy and inflammation), lymphoid follicle formation in the bone marrow, and severe decreases in circulating B-lymphocytes in neonates. The cause of the neonatal deaths is uncertain; however, both affected neonates were found to have bacterial infections.
Reduced testicular weight was observed in neonates at the high dose. A no-effect dose for adverse developmental effects was not identified; the doses tested in monkey are 2 and 10 times the recommended human dose of 600 mg, on a mg/kg basis.
8.2Lactation Risk Summary There are no data on the presence of ocrelizumab in human milk, the effects on the breastfed infant, or the effects of the drug on milk production. Ocrelizumab was excreted in the milk of ocrelizumab-treated monkeys. Human IgG is excreted in human milk, and the potential for absorption of ocrelizumab to lead to B-cell depletion in the infant is unknown.
The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for OCREVUS and any potential adverse effects on the breastfed infant from OCREVUS or from the underlying maternal condition.
8.3Females and Males of Reproductive Potential Contraception Females of reproductive potential should use effective contraception while receiving OCREVUS and for 6 months after the last infusion of OCREVUS [see Clinical Pharmacology (12.3) ] .
8.4Pediatric Use The safety and effectiveness of OCREVUS for the treatment of relapsing-remitting MS have been established in pediatric patients 10 years of age and older who weigh 25 kg or more. Use of OCREVUS for this indication is supported by evidence from one randomized, double-blind clinical study in 187 pediatric patients (93 of whom received OCREVUS) and additional pharmacokinetic data in pediatric patients [see Clinical Pharmacology (12.3) and Clinical Studies (14.4) ] . The overall safety profile in pediatric patients 10 years of age and older receiving OCREVUS…

8.5Geriatric Use Clinical studies of OCREVUS did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects.
🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action The precise mechanism by which ocrelizumab exerts its therapeutic effects in multiple sclerosis is unknown, but is presumed to involve binding to CD20, a cell surface antigen present on pre-B and mature B lymphocytes. Following cell surface binding to B lymphocytes, ocrelizumab results in antibody-dependent cellular cytolysis and complement-mediated lysis.
12.2Pharmacodynamics For B-cell counts, assays for CD19 + B-cells are used because the presence of OCREVUS interferes with the CD20 assay. Treatment with OCREVUS reduces CD19 + B-cell counts in blood by 14 days after infusion in adult and pediatric patients. In clinical studies in adults, B-cell counts rose to above the lower limit of normal (LLN) or above baseline counts between infusions of OCREVUS at least one time in 0.3% to 4.1% of patients.
In a clinical study of 51 adult patients, the median time for B-cell counts to return to either baseline or LLN was 72 weeks (range 27-175 weeks) after the last OCREVUS infusion. Within 2.5 years after the last infusion, B-cell counts rose to either baseline or LLN in 90% of adult patients.
12.3Pharmacokinetics Pharmacokinetics (PK) of OCREVUS in MS clinical studies fit a two compartment model with time-dependent clearance. The overall exposure at the steady-state (AUC over the 24 week dosing intervals) of OCREVUS was 3,510 mcg/mL per day. In clinical studies in adult MS patients, maintenance doses of ocrelizumab were either 600 mg every 6 months (RMS patients) or two 300 mg infusions separated by 14 days every 6 months (PPMS patients).
The mean maximum concentration was 212 mcg/mL in patients with RMS (600 mg infusion over 3.5 hours) and 141 mcg/mL in patients with PPMS (two 300 mg infusions over 2.5 hours administered within two weeks). The mean maximum peak concentrations (C max ) of ocrelizumab in patients with relapsing-remitting multiple sclerosis (RRMS) observed after the 3.5-hour infusion and 2-hour infusion were 202 ± 42 (mean ± SD) and 200 ± 46 mcg/mL, respectively, compared to the previously reported C max of 212 mcg/mL. The pharmacokinetics of ocrelizumab was essentially linear and dose proportional between 400 mg and 2000 mg.
Distribution The population PK estimate of the central volume of distribution was
2.78L. Peripheral volume and inter-compartment clearance were estimated at
2.68 L and
0.29L/day, respectively. Elimination Constant clearance was estimated at
0.17 L/day, and initial time-dependent clearance at
0.05L/day, which declined with a half-life of 33 weeks. The terminal elimination half-life was 26 days. Metabolism The metabolism of OCREVUS has not been directly studied because antibodies are cleared principally by catabolism.
Specific Populations Pediatric Patients The median AUC over the first 24-week dosing interval was 3130 mcg/mL per day, and C max was 147 mcg/mL, in patients 10 years to less than 18 years of age receiving OCREVUS 600 mg (body weight ≥ 35 kg) or 300 mg (body weight < 35 kg). Renal Impairment Patients with mild renal impairment were included in clinical trials. No significant change in the pharmacokinetics of OCREVUS was observed in those patients.
Hepatic Impairment Patients with mild hepatic impairment were included in clinical trials. No significant change in the pharmacokinetics of OCREVUS was observed in those patients.
12.6Immunogenicity The observed incidence of anti-drug antibodies is highly dependent on the sensitivity and specificity of the assay. Differences in assay methods preclude meaningful comparisons of the incidence of anti-drug antibodies in other studies, including those of OCREVUS or of other ocrelizumab products. Patients in MS trials (Study 1, Study 2, Study 3, and Study 5) were tested at multiple time points (baseline and every 6 months post-treatment for the duration of the trial) for anti-drug antibodies (ADAs).
In Studies 1, 2, and 3, 12 (~1%) out of 1131 adult patients tested positive for ADAs, of which 2…
🧬 Mechanism of Action ▾
12.1Mechanism of Action The precise mechanism by which ocrelizumab exerts its therapeutic effects in multiple sclerosis is unknown, but is presumed to involve binding to CD20, a cell surface antigen present on pre-B and mature B lymphocytes. Following cell surface binding to B lymphocytes, ocrelizumab results in antibody-dependent cellular cytolysis and complement-mediated lysis.
