UDENYCA- pegfilgrastim injection, solution
Coherus BioSciences Inc

1 INDICATIONS AND USAGE

1.1 Patients with Cancer Receiving Myelosuppressive Chemotherapy

UDENYCA is indicated to decrease the incidence of infection, as manifested by febrile neutropenia, in patients with non-myeloid malignancies receiving myelosuppressive anti-cancer drugs associated with a clinically significant incidence of febrile neutropenia [see Clinical Studies (14.1)].

Limitations of Use

UDENYCA is not indicated for the mobilization of peripheral blood progenitor cells for hematopoietic stem cell transplantation.

1.2 Patients with Hematopoietic Subsyndrome of Acute Radiation Syndrome

UDENYCA is indicated to increase survival in patients acutely exposed to myelosuppressive doses of radiation [see Dosage and Administration (2.2) and Clinical Studies (14.2)].

2 DOSAGE AND ADMINISTRATION

2.1 Patients with Cancer Receiving Myelosuppressive Chemotherapy

The recommended dosage of UDENYCA is a single subcutaneous injection of 6 mg administered once per chemotherapy cycle. For dosing in pediatric patients weighing less than 45 kg, refer to Table 1. Do not administer UDENYCA between 14 days before and 24 hours after administration of cytotoxic chemotherapy.

2.2 Patients with Hematopoietic Subsyndrome of Acute Radiation Syndrome

The recommended dose of UDENYCA is two doses, 6 mg each, administered subcutaneously one week apart. For dosing in pediatric patients weighing less than 45 kg, refer to Table 1. Administer the first dose as soon as possible after suspected or confirmed exposure to radiation levels greater than 2 gray (Gy). Administer the second dose one week after the first dose.

Obtain a baseline complete blood count (CBC). Do not delay administration of UDENYCA if a CBC is not readily available. Estimate a patient’s absorbed radiation dose (i.e., level of radiation exposure) based on information from public health authorities, biodosimetry if available, or clinical findings such as time to onset of vomiting or lymphocyte depletion kinetics.

2.3 Administration

UDENYCA is administered subcutaneously via a single-dose prefilled autoinjector, a single-dose prefilled syringe for manual use or for use with the on-body injector (OBI) for UDENYCA, which is co-packaged with a single dose prefilled syringe for OBI. Use of the OBI for UDENYCA is not recommended for patients with Hematopoietic Subsyndrome of Acute Radiation Syndrome. Use of the OBI has not been studied in pediatric patients.

Prior to use‚ remove the carton from the refrigerator and allow UDENYCA to reach room temperature for a minimum of 30 minutes. Discard any UDENYCA left at room temperature for greater than 48 hours.

Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. Do not administer UDENYCA if discoloration or particulates are observed.

The needle cap on the prefilled syringe and prefilled autoinjector is not made with natural rubber latex.

Pediatric Patients Weighing Less than 45 kg

The UDENYCA prefilled syringe is not designed to allow for direct administration of doses less than 0.6 mL (6 mg). The syringe does not bear graduation marks which are necessary to accurately measure doses of UDENYCA less than 0.6 mL (6 mg) for direct administration to patients. Thus, the direct administration to patients requiring dosing of less than 0.6 mL (6 mg) is not recommended due to the potential for dosing errors. Refer to Table 1.

Table 1. Dosing of UDENYCA for pediatric patients weighing less than 45 kg
*
For pediatric patients weighing less than 10 kg, administer 0.1 mg/kg (0.01 mL/kg) of UDENYCA
Body Weight UDENYCA Dose Volume to Administer
Less than 10 kg * See below * See below *
10 — 20 kg 1.5 mg 0.15 mL
21 — 30 kg 2.5 mg 0.25 mL
31 — 44 kg 4 mg 0.4 mL

The UDENYCA prefilled autoinjector is not suitable for use in pediatric patients weighing less than 45 kg. The UDENYCA prefilled autoinjector delivers the entire contents (6 mg in 0.6 mL) in a single injection and is not adjustable.

2.4 Advice to Give to Patients or Caregivers Regarding Administration via the Prefilled Autoinjector

Only adults can self-administer UDENYCA with the prefilled autoinjector. If subcutaneous injections can be given at home, refer the patient or caregiver to the dose delivery information provided in the Instructions for Use. Provide training to patients or caregivers to ensure they understand how to administer UDENYCA via the prefilled autoinjector. Ensure patients or caregivers understand how to identify that a full dose has been administered by listening for the second ‘click’ and checking that the ‘Orange Indicator’ completely blocks the viewing window. Instruct patients or caregivers using the prefilled autoinjector to notify their healthcare provider immediately in order to determine the need for a replacement dose of UDENYCA if they suspect that the full dose may not have been administered.

2.5 Special Healthcare Provider Instructions for the On-body Injector for UDENYCA

A healthcare provider must fill the on-body injector (OBI) with UDENYCA using the prefilled syringe and then apply the OBI for UDENYCA to the patient’s skin (abdomen or back of arm). The back of the arm may only be used if there is a caregiver available to monitor the status of the OBI for UDENYCA. Approximately 27 hours after the OBI for UDENYCA is applied to the patient’s skin, UDENYCA will be delivered over approximately 5 minutes. A healthcare provider may initiate administration with the OBI for UDENYCA on the same day as the administration of cytotoxic chemotherapy, as long as the OBI for UDENYCA delivers UDENYCA no less than 24 hours after administration of cytotoxic chemotherapy.

The prefilled syringe co-packaged in UDENYCA ONBODY must only be used with the OBI for UDENYCA. The prefilled syringe contains additional solution to compensate for liquid loss during filling of the OBI and delivery through the OBI for UDENYCA. If the prefilled syringe co-packaged in UDENYCA ONBODY is used for manual subcutaneous injection, the patient will receive an overdose. If the single-dose prefilled syringe for manual use is used with the OBI for UDENYCA, the patient may receive less than the recommended dose.

Do not use the OBI for UDENYCA to deliver any other drug product except the UDENYCA prefilled syringe co-packaged with the OBI for UDENYCA.

The OBI for UDENYCA should be applied to intact, non-irritated skin on the arm or abdomen.

A missed dose could occur due to an OBI for UDENYCA failure or leakage. If the patient misses a dose, a new dose should be administered by single-dose prefilled syringe for manual use, as soon as possible after detection.

Refer to the Healthcare Provider Instructions for Use for the OBI for UDENYCA for full administration information.

2.6 Advice to give to Patients Regarding Administration via the On-body Injector for UDENYCA

Advise patients to avoid activities such as traveling, driving, or operating heavy machinery during hours 26-29 following application of the on-body injector (OBI) for UDENYCA (this includes the 5-minute delivery period plus an hour post-delivery). Patients should have a caregiver nearby for the first use.

Refer the patient to the dose delivery information written on the Patient Instructions for Use. Provide training to patients to ensure they understand when the dose delivery of UDENYCA will begin and how to monitor the OBI for UDENYCA for completed delivery. Ensure patients understand how to identify signs of malfunction of OBI for UDENYCA [see Warnings and Precautions (5.12) and Patient Counseling Information (17)]. Instruct patients using the OBI to notify their healthcare professional immediately in order to determine the need for a replacement dose of UDENYCA if they suspect that the device may not have performed as intended [see Warnings and Precautions (5.12)].
