2.5       Instructions for Preparation

Preparation

1. Use aseptic technique to prepare DECNUPAZ.
   
2. DECNUPAZ is a hazardous drug. Follow applicable special handling and disposal procedures in accordance with local requirements.1
   
3. Determine the dose and the number of DECNUPAZ vials needed. More than one vial may be needed to achieve a full dose.
   
4. Remove the DECNUPAZ vial(s) from the refrigerator and allow the vial(s) to reach room temperature 15°C to 30°C (59℉ to 86°F) before use.

Reconstitution

1. Using a sterile syringe, reconstitute DECNUPAZ by slowly injecting 1.1 mL of Sterile Water for Injection into each vial to obtain a concentration of 2 mg/mL. Each single-dose vial contains 1 mL (2 mg) of withdrawable DECNUPAZ.
   
2. Gently swirl the vial in a circular motion. Do not shake.
   
3. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. The reconstituted solution in each vial should appear clear to slightly opalescent, colorless to slightly yellow and free of visible contaminants, particles and/or particulates. Do not use if discoloration or particulate matter is present.
   
4. DECNUPAZ contains no preservative. Use reconstituted solution immediately. If not used immediately, store the reconstituted DECNUPAZ vials in a refrigerator at 2°C to 8°C (36°F to 46°F) for up to 4 hours from the time of reconstitution. Do not freeze.  

First Dilution

1. DECNUPAZ must be diluted with 5% Dextrose Injection.
   
2. Add 4.8 mL of 5% Dextrose Injection to the reconstituted solution in the vial. Mix the diluted solution by gentle inversion. Do not shake.
   
3. The resulting diluted solution concentration is 0.4 mg/mL.
   
4. Calculate the required administration volume needed from the first dilution of vial(s).
   Volume needed from vial(s) after first dilution (mL) = Dose (mg) / 0.4 mg/mL
   
5. DECNUPAZ requires a second dilution prior to administration.

Second Dilution

1. Withdraw the calculated volume from the first dilution of vial(s) using an appropriately sized syringe.
   
2. Withdraw an equal volume of 5% Dextrose Injection in an appropriately sized second syringe.
   
3. Attach a connector to the two syringes and transfer DECNUPAZ into the syringe containing 5% Dextrose Injection.
   
4. Disconnect the syringes. Draw air into the syringe containing the DECNUPAZ diluted solution and close.  
   
5. Gently invert the syringe to mix the solution. Do not shake.
   
6. Remove air bubbles from the syringe before administration.
   
7. The final concentration is 0.2 mg/mL.
   
8. Discard any unused drug remaining in the vial(s).
   
9. Do not use an in-line filter due to increased drug loss. If an in-line filter is required, a 1.2 micron polyethersulfone (PES) filter can be used.

Storage of Diluted Solution

• Immediately use diluted DECNUPAZ solution.
  
• The total storage time from the start of dose preparation to completion of administration should not exceed 24 hours. Store the diluted solution of DECNUPAZ under refrigeration at 2°C to 8°C (36°F to 46°F) for no more than 24 hours, including up to 8 hours at room temperature at 9°C to 25°C (48°F to 77°F), from the time of reconstitution to completion of the intravenous infusion.
  
• Discard diluted infusion solution if storage time exceeds these limits.
  
• If refrigerated, allow approximately 30 minutes for the diluted solution to come to room temperature prior to administration. Do not shake.
  
• Do not freeze the diluted infusion solution.
  
• Protect from light during storage.
  
• Do not shake.

2.6       Administration

• After preparing the dose for infusion, visually inspect the syringe content for particulates and discard if present.
  
• Do not mix DECNUPAZ with any other drugs or any intravenous fluids other than 5% Dextrose Injection.
  
• Protect the intravenous syringe from light using a light-blocking cover during infusion. The infusion line does not need to be protected from light.
  
• Administer DECNUPAZ as an intravenous infusion only. Do not administer as an intravenous push or bolus.
  • The first infusion of DECNUPAZ should be administered at a rate of 0.8 mL/min (0.165 mg/min) for the first 30 minutes.
    
  • If well tolerated, the infusion rate can be increased after 30 minutes to 1.7 mL/min (0.33 mg/min), if necessary.
    
  • Subsequent infusions may be delivered at the highest tolerated rate.
  
  
• Following the infusion, flush the intravenous line with sufficient volume of 5% Dextrose Injection to ensure delivery of the full dose. Do not use any other intravenous fluids for flushing.

3.       DOSAGE FORMS AND STRENGTHS

For injection: 2 mg of pivekimab sunirine-pvzy as a white to off-white, lyophilized cake in a single-dose vial.

4.       CONTRAINDICATIONS

None.

5.       WARNINGS AND PRECAUTIONS

5.1       Hepatotoxicity, Including Hepatic Veno-occlusive Disease (VOD) (also known as Sinusoidal Obstruction Syndrome)

DECNUPAZ can cause hepatotoxicity, including VOD, a severe form of hepatotoxicity. In CADENZA, VOD occurred in 6% (7/116) of adult patients during treatment or following a subsequent hematopoietic stem cell transplantation (HSCT). Of the 7 total patients who developed VOD, 3 patients had treatment-naïve BPDCN and 4 patients had relapsed/refractory BPDCN. Among all 116 patients treated with DECNUPAZ at 0.045 mg/kg, VOD occurred in 2/116 (2%) during treatment, with onset up to 30 days after the last dose. Among 19 patients with BPDCN who proceeded to HSCT, VOD occurred in 5/19 patients (26%), including two fatal cases. The median time from subsequent HSCT to onset of VOD was 11 days (range: 7 – 25 days).

After receiving DECNUPAZ, patients should be closely monitored for signs and symptoms of VOD including elevations in ALT, AST, total bilirubin, hepatomegaly (which may be painful), rapid weight gain, and ascites. Monitor liver tests, including ALT, AST, and total bilirubin, prior to each dose of DECNUPAZ. Based on elevations of liver tests, delay DECNUPAZ. In patients who experience VOD, discontinue DECNUPAZ and treat according to standard medical practice [see Dosage and Administration (2.4)].

5.2       Infusion-Related Reactions

DECNUPAZ can cause serious, life-threatening infusion-related reactions (IRR); signs and symptoms of IRR include dyspnea, flushing, fever, chills, nausea, chest discomfort, hypotension, and vomiting. In CADENZA, IRRs occurred in 26% (30/116) of patients during treatment with DECNUPAZ at 0.045 mg/kg once every three weeks, including Grade 1 in 4.3% (5/116), Grade 2 in 16% (19/116), and Grade 3 in 5% (6/116) of patients. IRR occurred in Cycle 1 in 25% (29/116) of patients with decreasing frequency in subsequent cycles. IRR led to discontinuation in one patient.

Premedicate with a corticosteroid the day before infusion, and premedicate with a corticosteroid, antihistamine, and antipyretic prior to dosing [see Dosage and Administration (2.3)]. Premedication the day before infusion and prior to dosing led to reduced frequency and severity of IRRs.  

Monitor patients closely for potential IRR during the infusion and for at least four hours, or longer as clinically indicated, after the first infusion and for at least 1 hour after subsequent infusions.

Interrupt infusion of DECNUPAZ and institute appropriate medical management if an infusion-related reaction occurs. Depending on the severity of the infusion-related reaction, reduce infusion rate or permanently discontinue [see Dosage and Administration (2.4)].

5.3       Edema 

DECNUPAZ can cause edema and fluid retention, including serious events. In CADENZA, Grade 3-4 edema occurred in 16% (18/116) of patients treated with DECNUPAZ, including Grade 3-4 generalized edema in 2.6% (3/116) of patients [see Adverse Reactions (6.1)]. 

Monitor patients for new or worsening edema. For Grade 2 or Grade 3 edema, delay further dosing of DECNUPAZ until edema has returned to Grade 0-1 or baseline. For Grade 3 edema or Grade 2 edema with dose delay for more than 2 weeks, consider resuming at a lower dose. For Grade 4 edema, permanently discontinue. Institute appropriate medical management for edema [see Dosage and Administration (2.4)].

5.4       Sulfite Allergic Reactions

DECNUPAZ contains sodium metabisulfite, a sulfite that may cause allergic type reactions, including anaphylactic symptoms and life-threatening or less severe asthmatic episodes in certain susceptible people. The overall prevalence of sulfite sensitivity in the general population is unknown and probably low. Sulfite sensitivity is seen more frequently in asthmatic than in non-asthmatic people.

5.5       Embryo-Fetal Toxicity

Based on its mechanism of action, DECNUPAZ can cause embryo-fetal harm when administered to a pregnant woman because it contains a genotoxic compound (FGN849) and affects actively dividing cells [see Clinical Pharmacology (12.1), Nonclinical Toxicology (13.1)].

Advise patients of the potential risk to the fetus. Advise females of reproductive potential to use effective contraception during treatment with DECNUPAZ and for 7 months after the last dose. Advise male patients with female partners of reproductive potential to use effective contraception during treatment with DECNUPAZ, and for 4 months after the last dose [see Use in Specific Populations (8.1, 8.3)].

6.       ADVERSE REACTIONS

The following clinically significant adverse reactions are discussed elsewhere in the labeling:

• Hepatotoxicity, Including Hepatic VOD (also known as Sinusoidal Obstruction Syndrome) [see Warnings and Precautions (5.1)]
  
• Infusion-Related Reactions [see Warnings and Precautions (5.2)]
  
• Edema [see Warnings and Precautions (5.3)]

6.1       Clinical 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 safety of DECNUPAZ was evaluated in CADENZA, a single-arm, open-label study that included 116 adults with newly diagnosed or relapsed/refractory myeloid malignancies, including 84 with BPDCN, treated with DECNUPAZ 0.045 mg/kg once every three weeks.

The median number of cycles administered was 3 (range: 1 to 34) in the overall population, and 3.5 (range: 1 to 34) in patients with BPDCN.

Serious adverse reactions occurred in 55% of patients treated with DECNUPAZ. The most common (≥2%) serious adverse reactions were febrile neutropenia, pneumonia, edema, sepsis, hemorrhage, thrombosis, infusion-related reactions, viral infection, pneumonitis, infections without specified pathogens, pyrexia, and musculoskeletal pain. Fatal adverse reactions occurred in 4.3% of patients who received DECNUPAZ, including cardiac arrest (0.9%), clostridium difficile infection (0.9%), failure to thrive (0.9%), depressed level of consciousness (0.9%), and respiratory failure (0.9%).

Permanent discontinuation due to adverse reactions occurred in 10% of patients who received DECNUPAZ. Adverse reactions which resulted in permanent discontinuation of DECNUPAZ in ≥1% of patients included veno-occlusive disease and pneumonitis.

Dosage interruptions of DECNUPAZ due to adverse reactions occurred in 37% of patients. Adverse reactions which resulted in dosage interruptions in ≥2% of patients included edema, pneumonia, infusion-related reaction, bacterial infections, fatigue, hemorrhage, neutropenia, pneumonitis, and pyrexia.

Dose reductions of DECNUPAZ due to an adverse reaction occurred in 6% of patients. Adverse reactions which required dose reductions in ≥2% of patients included edema. 

The most common adverse reactions (≥20%) were edema, fatigue, musculoskeletal pain, hemorrhage, infusion-related reactions, nausea, and diarrhea. The most common Grade 3 to 4 laboratory abnormalities (≥10%) were neutrophils decreased, platelets decreased, lymphocyte count decreased, white blood cells decreased, hemoglobin decreased, and glucose increased.

Table 3 summarizes the common adverse reactions (≥10%) in patients treated with DECNUPAZ in CADENZA.

7.       DRUG INTERACTIONS

7.1       Effect of Other Drugs on DECNUPAZ

Strong and moderate CYP3A inhibitors

Closely monitor patients for adverse reactions with DECNUPAZ when used concomitantly with strong and moderate CYP3A inhibitors.

FGN849 is a substrate of CYP3A [see Clinical Pharmacology (12.3)]. Concomitant use of DECNUPAZ with strong and moderate CYP3A inhibitors may increase unconjugated FGN849 exposure, which may increase the risk of DECNUPAZ adverse reactions.  

8.       USE IN SPECIFIC POPULATIONS

8.1       Pregnancy

Risk Summary

Based on its mechanism of action, DECNUPAZ can cause embryo-fetal harm when administered to a pregnant woman because it contains a genotoxic compound (FGN849) and affects actively dividing cells [see Clinical Pharmacology (12.1), Nonclinical Toxicology (13.1)]. There are no available data on the use of DECNUPAZ in pregnant women to inform a drug-associated risk. Advise patients of the potential risks to a fetus.

In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively.

Animal reproductive or developmental toxicity studies were not conducted with pivekimab sunirine-pvzy. The cytotoxic component of DECNUPAZ, FGN849, is a DNA-alkylating agent that is toxic to rapidly dividing cells, indicating it has the potential to cause embryofetal lethality and teratogenicity.

8.2       Lactation

Risk Summary

There are no data on the presence of pivekimab sunirine-pvzy or its metabolites in human milk, the effects on the breastfed child, or the effects on milk production. Because of the potential for serious adverse reactions in breastfed children, advise women not to breastfeed during treatment with DECNUPAZ and for 1 month after the last dose.

8.3       Females and Males of Reproductive Potential

DECNUPAZ can cause fetal harm when administered to a pregnant patient [see Use in Specific Populations (8.1)].

Pregnancy Testing

Verify pregnancy status in females of reproductive potential prior to initiation of DECNUPAZ.

Contraception

Females

Advise females of reproductive potential to use effective contraception during treatment with DECNUPAZ and for 7 months after the last dose.

Males

Because of the potential for genotoxicity, advise males with female partners of reproductive potential to use effective contraception during treatment with DECNUPAZ and for 4 months after the last dose [see Nonclinical Toxicology (13.1)].

Infertility

Based on its mechanism of action, DECNUPAZ may impair male and female reproductive function and fertility.

8.4       Pediatric Use

The safety and effectiveness of DECNUPAZ have not been established in pediatric patients.

8.5       Geriatric Use

Of the 116 patients who were treated in CADENZA, 70% of patients were ≥65 years of age and 28% were ≥75 years of age. No overall differences in safety or effectiveness of DECNUPAZ have been observed between patients 65 years of age and older and younger adult patients.

Age does not have a clinically meaningful effect on the pharmacokinetics of DECNUPAZ [see Clinical Pharmacology (12.3)].

8.6       Renal Impairment

Avoid use of DECNUPAZ in patients with moderate to severe renal impairment (CLcr <60 mL/min, estimated by Cockcroft-Gault) or patients with end stage renal disease. A higher incidence of Grade ≥3 adverse events, serious adverse events, and dose delays was observed in patients with moderate renal impairment (CLcr 30 to <60 mL/min). DECNUPAZ has not been studied in patients with severe renal impairment (CLcr <30 mL/min) or end stage renal disease. 

No dosage adjustment of DECNUPAZ is recommended for patients with mild renal impairment (CLcr 60 to <90 mL/min, estimated by Cockcroft-Gault) [see Clinical Pharmacology (12.3)].

8.7       Hepatic Impairment

Avoid use of DECNUPAZ in patients with moderate to severe hepatic impairment (total bilirubin >1.5 x ULN with any AST). Limited data are available in patients with moderate hepatic impairment (total bilirubin >1.5 to 3 times ULN and any AST). DECNUPAZ has not been studied in patients with severe hepatic impairment.

No dosage adjustment of DECNUPAZ is recommended for patients with mild hepatic impairment (total bilirubin ≤ULN and AST >ULN or total bilirubin ≤1.5 times ULN and any AST) [see Clinical Pharmacology (12.3)].

11.       DESCRIPTION

Pivekimab sunirine-pvzy is a CD123-directed antibody and alkylating agent conjugate created by conjugating the IgG1 monoclonal antibody G4723A to the DGN549C linker-payload. The antibody-drug conjugate (ADC) contains approximately two DGN549C molecules sulfonated prior to conjugation and bound to the heavy chains (HC) of the G4723A antibody. Pivekimab sunirine-pvzy has an approximate molecular weight of 148 kDa. Pivekimab sunirine-pvzy is produced by site directed chemical conjugation of the antibody and small molecule components. The antibody is produced by mammalian (Chinese hamster ovary) cells, and the small molecule components are produced by chemical synthesis.

Pivekimab sunirine-pvzy has the following structure:

DECNUPAZ (pivekimab sunirine-pvzy) for injection is a sterile, lyophilized cake in a single-dose vial for reconstitution and dilution. DECNUPAZ is supplied as 2 mg per vial and requires reconstitution with Sterile Water for Injection, USP (1.1 mL) to obtain a concentration of 2 mg/mL. Following reconstitution, each mL delivers 2 mg of pivekimab sunirine-pvzy, methionine (0.45 mg), polysorbate 20 (0.1 mg), sodium hydroxide (0.2 mg), sodium metabisulfite (0.0048 mg), succinic acid (1.2 mg), trehalose (71.7 mg), and Sterile Water for Injection. The pH is 4.2.  

12.       CLINICAL PHARMACOLOGY

12.1       Mechanism of Action

Pivekimab sunirine-pvzy is a CD123 (alpha-subunit of the interleukin-3 receptor)-directed antibody-drug conjugate (ADC). The antibody is a humanized anti-CD123 IgG1. Pivekimab sunirine-pvzy binds to CD123 expressing cells and upon intracellular processing releases a cell membrane-permeable payload, FGN849, leading to DNA alkylation, single-strand DNA breaks, apoptosis, and cell death. The payload, FGN849, is a member of the indolinobenzodiazepine pseudodimer (IGN) class of cytotoxic molecules. Pivekimab sunirine-pvzy exhibited antitumor activity in in vitro and in vivo models of BPDCN.

12.2       Pharmacodynamics

Exposure-Response Relationships

Higher FGN849 (cytotoxic component of DECNUPAZ) exposure was associated with increased rates of Grade ≥2 infusion-related reactions.

Cardiac Electrophysiology

There is insufficient information to characterize the effect of pivekimab sunirine-pvzy on the QTc interval.

In 116 patients who received DECNUPAZ 0.045 mg/kg once every 3 weeks in CADENZA, 0.9% of patients had QTcF greater than 500 ms.

12.3       Pharmacokinetics

Pivekimab sunirine-pvzy and FGN849 pharmacokinetics were observed at Cycle 1 in patients in CADENZA at the approved recommended dosage and are presented as mean (CV%), unless otherwise specified. The exposure parameters of pivekimab sunirine-pvzy (ADC) and unconjugated FGN849 are summarized in Table 5. The Cmax and AUC of the ADC increased more than proportionally over a dose range of 0.045 to 0.18 mg/kg (the approved recommended dose to 4 times the recommended dose). ADC time to maximum concentrations (Tmax) occurred approximately at the end of the infusion, while FGN849 Tmax occurred approximately 2 hours after the end of infusion. There was no accumulation of the ADC or FGN849 in Cycle 3.

	Pivekimab sunirine-pvzy; Geometric mean (%CV)	Unconjugated FGN849; Geometric mean (%CV)
Cmax	442 (169) ng/mL	58.8 (110) pg/mL
AUClast	892 (101) ngh/mL	171 (128) pgh/mL

Cmax=maximum concentration, AUClast=area under the concentration from time zero to the last quantifiable concentration

Distribution

Pivekimab sunirine-pvzy volume of distribution is 5.4 L (39).

FGN849 plasma protein binding is 99.6% in vitro.

Elimination

Pivekimab sunirine-pvzy elimination half-life is approximately 1.5 hours at the 0.045 mg/kg every 3 weeks dosage. 

Pivekimab sunirine-pvzy clearance is 1.8 L/hour (76). 

Metabolism

Pivekimab sunirine-pvzy is expected to be catabolized into small peptides and amino acids. FGN849 is primarily metabolized by CYP3A.

Specific Populations

No clinically significant differences in the pharmacokinetics of pivekimab sunirine-pvzy or FGN849 were observed for age (19 to 91 years), body weight (45 to 160 kg), mild hepatic impairment (total bilirubin >ULN to 1.5 times ULN and any AST), or CLcr 60 to <90 mL/min (estimated by Cockcroft-Gault). Higher pivekimab sunirine-pvzy exposure and lower FGN849 exposure were observed in female patients compared to those in male patients.

The pharmacokinetics of pivekimab sunirine-pvzy in patients with moderate to severe hepatic impairment (total bilirubin >1.5 times ULN with any AST) or CLcr <60 mL/min is unknown. 

Drug Interaction Studies

No dedicated clinical studies evaluating the drug-drug interaction potential of pivekimab sunirine-pvzy have been conducted.

In Vitro Studies

Cytochrome P450 (CYP) Enzymes: FGN849 is primarily a CYP3A substrate but is not a significant substrate of CYP1A2, CYP2B6, CYP2C8, CYP2C9, CYP2C19, or CYP2D6. FGN849 is an inhibitor of CYP3A and CYP2C8 but is not an inhibitor of CYP1A2, CYP2B6, CYP2C9, CYP2C19, or CYP2D6.

Transporter systems: FGN849 is a substrate of P-gp and BCRP but is not a substrate of MATE1, MATE2-K, OAT1, OAT3, OATP1B1, OATP1B3, or OCT2. FGN849 is not an inhibitor of P-gp, BCRP, MATE1, MATE2-K, OAT1, OAT3, OATP1B1, OATP1B3, or OCT2.

12.6       Immunogenicity

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 study described below with the incidence of ADA in other studies, including those of pivekimab sunirine-pvzy.

Following administration of pivekimab sunirine-pvzy in CADENZA in BPDCN patients, 19/80 (24%) of patients tested positive for treatment emergent antibodies against pivekimab sunirine-pvzy. Of those who tested positive for anti-drug antibody, neutralizing antibodies were detected in 14/18 (78%) of evaluable patients. There was no identified clinically significant effect of anti-drug antibodies on pharmacokinetics, safety, or effectiveness of pivekimab sunirine-pvzy.

13.       NONCLINICAL TOXICOLOGY

13.1       Carcinogenesis, Mutagenesis, Impairment of Fertility

Carcinogenesis

Carcinogenicity studies have not been conducted with pivekimab sunirine-pvzy or the small molecule FGN849.

Mutagenesis

FGN849 was mutagenic in the bacterial reverse mutation (Ames) assay and clastogenic in the in vitro and in vivo (rat) micronucleus assays. These results are consistent with the pharmacological mechanism of action of DNA alkylation that induces G2-M phase arrest of dividing cells resulting in cell death.

Impairment of Fertility

Fertility studies have not been conducted with pivekimab sunirine-pvzy or FGN849.
