Engraftment syndrome: Engraftment syndrome may progress to multiorgan failure and death. Treat engraftment syndrome promptly with corticosteroids. [See Warnings and Precautions (5.4)]

Graft failure: Graft failure may be fatal. Monitor patients for laboratory evidence of hematopoietic recovery. Prior to choosing a specific unit of HPC, Cord Blood, consider testing for HLA antibodies to identify patients who are alloimmunized. [See Warnings and Precautions (5.5)]

HPC (hematopoietic progenitor cells), Cord Blood is an allogeneic cord blood hematopoietic progenitor cell therapy indicated for use in unrelated donor hematopoietic progenitor stem cell transplantation procedures in conjunction with an appropriate preparative regimen for hematopoietic and immunologic reconstitution in patients with disorders affecting the hematopoietic system that are inherited, acquired, or result from myeloablative treatment. The risk benefit assessment for an individual patient depends on the patient characteristics, including disease, stage, risk factors, and specific manifestations of the disease, on characteristics of the graft, and on other available treatments or types of hematopoietic progenitor cells. HPC (hematopoietic progenitor cells), Cord Blood is an allogeneic cord blood hematopoietic progenitor cell therapy indicated for use in unrelated donor hematopoietic progenitor cell transplantation procedures in conjunction with an appropriate preparative regimen for hematopoietic and immunologic reconstitution in patients with disorders affecting the hematopoietic system that are inherited, acquired, or result from myeloablative treatment. (1) The risk benefit assessment for an individual patient depends on the patient characteristics, including disease, stage, risk factors, and specific manifestations of the disease, on characteristics of the graft, and on other available treatments or types of hematopoietic progenitor cells. (1)

For intravenous use only. Do not irradiate. Unit selection and administration of HPC, Cord Blood should be done under the direction of a physician experienced in hematopoietic progenitor cell transplantation. The recommended minimum dose is 2.5 x 10⁷ nucleated cells/kg at cryopreservation. (2.1) Do not administer HPC, Cord Blood through the same tubing with other products except for normal saline. (2.3)

The recommended minimum dose is 2.5 x 107 nucleated cells/kg at cryopreservation. Multiple units may be required in order to achieve the appropriate dose. Matching for at least 4 of 6 HLA-A antigens, HLA-B antigens, and HLA-DRB1 alleles is recommended. The HLA typing and nucleated cell content for each individual unit of HPC, Cord Blood are documented on the container label and/or in accompanying records.

HPC, Cord Blood should be prepared by a trained healthcare professional. Do not irradiate HPC, Cord Blood. See the appended detailed instructions for preparation of HPC, Cord Blood for infusion. Once prepared for infusion, HPC, Cord Blood may be stored at 1 to 8°C for up to 4 hours. The recommended limit on DMSO administration is 1 gram per kg body weight per day. [See Warnings and Precautions (5.2)]

HPC, Cord Blood should be administered under the supervision of a qualified healthcare professional experienced in hematopoietic progenitor cell transplantation. Confirm the identity of the patient for the specified unit of HPC, Cord Blood prior to administration. Confirm that emergency medications are available for use in the immediate area. Ensure the patient is hydrated adequately. Premedicate the patient 30 to 60 minutes before the administration of HPC, Cord Blood. Premedications can include any or all of the following: antipyretic, histamine blocker, and corticosteroids. Inspect the product for any abnormalities such as unusual particulates and for breaches of container integrity prior to administration. Prior to infusion, discuss all such product irregularities with the laboratory issuing the product for infusion. Administer HPC, Cord Blood by intravenous infusion. Do not administer in the same tubing concurrently with products other than 0.9% Sodium Chloride, Injection (USP). HPC, Cord Blood may be filtered through a 170 to 260 micron filter designed to remove clots. Do NOT use a filter designed to remove leukocytes. For adults, begin infusion of HPC, Cord Blood at 100 milliliters per hour and increase the rate as tolerated. For children, begin infusion of HPC, Cord Blood at 1 milliliter per kg per hour and increase as tolerated. The infusion rate should be reduced if the fluid load is not tolerated. The infusion should be discontinued in the event of an allergic reaction or if the patient develops a moderate to severe infusion reaction. [See Warnings and Precautions (5) and Adverse Reactions (6)] Monitor the patient for adverse reactions during, and for at least six hours after, administration. Because HPC, Cord Blood contains lysed red cells that may cause renal failure, careful monitoring of urine output is also recommended.

Each unit of HPC, Cord Blood contains a minimum of 5.0 x 108 total nucleated cells with a minimum of 1.25 x 106 viable CD34+ cells, suspended in 10% dimethyl sulfoxide (DMSO) and 1% Dextran 40, at the time of cryopreservation. The exact pre-cryopreservation nucleated cell content is provided on the container label and in accompanying records. Each unit contains a minimum of 5 x 108 total nucleated cells with at least 1.25 x 106 viable CD34+ cells at the time of cryopreservation. The exact pre-cryopreservation nucleated cell content of each unit is provided on the container label and accompanying records. (3)

HPC, Cord Blood is contraindicated in patients with known hypersensitivity to dimethyl sulfoxide (DMSO), Dextran 40 or plasma proteins. [See Description (11) and Dosage and Administration (2.2)] Known sensitivity to dimethyl sulfoxide (DMSO), Dextran 40 or plasma proteins. (4)

Allergic Reactions and Anaphylaxis (5.1) Infusion Reactions (5.2) Graft-versus-Host Disease (5.3) Engraftment Syndrome (5.4) Graft Failure (5.5) Malignancies of Donor Origin (5.6) Transmission of Serious Infections (5.7) Transmission of Rare Genetic Diseases (5.8)

Allergic reactions may occur with infusion of HPC, Cord Blood. Reactions include bronchospasm, wheezing, angioedema, pruritus and hives [see Adverse Reactions (6)]. Serious hypersensitivity reactions, including anaphylaxis, also have been reported. These reactions may be due to dimethyl sulfoxide (DMSO), Dextran 40, or a plasma component of HPC, Cord Blood.

Infusion reactions are expected to occur and include nausea, vomiting, fever, rigors or chills, flushing, dyspnea, hypoxemia, chest tightness, hypertension, tachycardia, bradycardia, dysgeusia, hematuria, and mild headache. Premedication with antipyretic, histamine antagonists, and corticosteroids may reduce the incidence and intensity of infusion reactions. Severe reactions, including respiratory distress, severe bronchospasm, severe bradycardia with heart block or other arrhythmias, cardiac arrest, hypotension, hemolysis, elevated liver enzymes, renal compromise, encephalopathy, loss of consciousness, and seizure also may occur. Many of these reactions are related to the amount of DMSO administered. Minimizing the amount of DMSO administered may reduce the risk of such reactions, although idiosyncratic responses may occur even at DMSO doses thought to be tolerated. The actual amount of DMSO depends on the method of preparation of the product for infusion. Limiting the amount of DMSO infused to no more than 1 gm/kg/day is recommended. [See Overdosage (10)] If infusing more than one unit of HPC, Cord Blood on the same day, do not administer subsequent units until all signs and symptoms of infusion reactions from the prior unit have resolved. Infusion reactions may begin within minutes of the start of infusion of HPC, Cord Blood, although symptoms may continue to intensify and not peak for several hours after completion of the infusion. Monitor the patient closely during this period. When a reaction occurs, discontinue the infusion and institute supportive care as needed.

Acute and chronic graft-versus-host disease (GVHD) may occur in patients who have received HPC, Cord Blood. Classic acute GVHD is manifested as fever, rash, elevated bilirubin and liver enzymes, and diarrhea. Patients transplanted with HPC, Cord Blood also should receive immunosuppressive drugs to decrease the risk of GVHD. [See Adverse Reactions (6.1)

Engraftment syndrome is manifested as unexplained fever and rash in the peri-engraftment period. Patients with engraftment syndrome also may have unexplained weight gain, hypoxemia, and pulmonary infiltrates in the absence of fluid overload or cardiac disease. If untreated, engraftment syndrome may progress to multiorgan failure and death. Begin treatment with corticosteroids once engraftment syndrome is recognized in order to ameliorate the symptoms. [See Adverse Reactions (6.1)]

Primary graft failure, which may be fatal, is defined as failure to achieve an absolute neutrophil count greater than 500/uL blood by Day 42 after transplantation. Immunologic rejection is the primary cause of graft failure. Patients should be monitored for laboratory evidence of hematopoietic recovery. Consider testing for HLA antibodies in order to identify patients who are alloimmunized prior to transplantation and to assist with choosing a unit with a suitable HLA type for the individual patient. [See Adverse Reactions (6.1)]

Patients who have undergone HPC, Cord Blood transplantation may develop post-transplant lymphoproliferative disorder (PTLD), manifested as a lymphoma-like disease favoring non-nodal sites. PTLD is usually fatal if not treated. The incidence of PTLD appears to be higher in patients who have received antithymocyte globulin. The etiology is thought to be donor lymphoid cells transformed by Epstein-Barr virus (EBV). Serial monitoring of blood for EBV DNA may be warranted in high-risk groups. Leukemia of donor origin also has been reported in HPC, Cord Blood recipients. The natural history is presumed to be the same as that for de novo leukemia.

Transmission of infectious disease may occur because HPC, Cord Blood is derived from human blood. Disease may be caused by known or unknown infectious agents. Donors are screened for increased risk of infection with human immunodeficiency virus (HIV), human T-cell lymphotropic virus (HTLV), hepatitis B virus (HBV), hepatitis C virus (HCV), T. pallidum, T. cruzi, West Nile Virus (WNV), transmissible spongiform encephalopathy (TSE) agents, and vaccinia. Donors are also screened for clinical evidence of sepsis, and communicable disease risks associated with xenotransplantation.  Maternal blood samples are tested for HIV types 1 and 2, HTLV types I and II, HBV, HCV, T. pallidum, WNV, and T. cruzi. These measures do not totally eliminate the risk of transmitting these or other transmissible infectious diseases and disease agents. Report the occurrence of a transmitted infection to ClinImmune Labs, University of Colorado Cord Blood Bank (UCCBB) at 303-724-1306. Testing is also performed for evidence of donor infection due to cytomegalovirus (CMV); however, this is not a donor selection criterion. The result may be found on the container label and/or in accompanying records.

HPC, Cord Blood may transmit rare genetic diseases involving the hematopoietic system for which donor screening and/or testing has not been performed [see Adverse Reactions (6.1)]. Cord blood donors have been screened by family history to exclude inherited disorders of the blood and marrow. HPC, Cord Blood has been tested to exclude donors with sickle cell anemia, and anemias due to abnormalities in hemoglobins C, D, and E. Because of the age of the donor at the time HPC, Cord Blood collection takes place, the ability to exclude rare genetic diseases is severely limited.

Day-100 mortality from all causes was 25%. The most common infusion-related adverse reactions (≥5%) are hypertension, vomiting, nausea, bradycardia, and fever. (6.1) Mortality, from all causes, at 100 days post-transplant was 25%. (6.1) The most common infusion-related adverse reactions (≥5%) are hypertension, vomiting, nausea, bradycardia, and fever. (6.1) To report SUSPECTED ADVERSE REACTIONS, contact ClinImmune Labs, University of Colorado Cord Blood Bank (UCCBB) at 303-724-1306 and FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.

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.

Infusion Reactions The data described in Table 1 reflect exposure to 442 infusions of HPC, Cord Blood (from multiple cord blood banks) in patients treated using a total nucleated cell dose ≥2.5 x 10⁷/kg on a single-arm trial or expanded access use (The COBLT Study). The population was 60% male, and the median age was 5 years (range 0.05-68 years), and included patients treated for hematologic malignancies, inherited metabolic disorders, primary immunodeficiencies, and bone marrow failure. Preparative regimens and graft-vs-host disease prophylaxis were not standardized. The most common infusion reactions were hypertension, vomiting, nausea, and bradycardia. Hypertension and any grades 3-4 infusion-related reactions occurred more frequently in patients receiving volumes greater than 150 milliliters and in pediatric patients. The rate of serious adverse cardiopulmonary reactions was 0.8%.

Table 1. Incidence of Infusion-Related Adverse Reactions Occurring in ≥1% of Infusions (The COBLT Study)

	Any grade	Grade 3-4
Any reaction	65.4%	27.6%
Hypertension	48.0%	21.3%
Vomiting	14.5%	0.2%
Nausea	12.7%	5.7%

Hypoxia	2.0%	2.0%

Information on infusion reactions was available from voluntary reports for 47 patients who received HPC, Cord Blood from ClinImmune Labs at a total nucleated cell dose ≥2.5 x 10⁷/kg. The population included 72% males and 28% females, with median age 12 years (range 0.4 - 67.5 years). Preparative regimens and graft-vs-host disease prophylaxis were not standardized. Seventeen patients (36%) had an infusion reaction. Infusion reactions included hypertension, nausea, vomiting, facial flushing, hypoxia, headache, fever and chills, hematuria, and bradycardia.

Other Adverse Reactions For other adverse reactions, the raw clinical data from the docket were pooled for 1299 patients (120 adult and 1179 pediatric) transplanted with HPC, Cord Blood (from multiple cord blood banks) with total nucleated cell dose ≥2.5 x 107/kg. Sixty-six percent (n=862) underwent transplantation as treatment for hematologic malignancy. The preparative regimens and graft-vs-host disease prophylaxis varied. The median total nucleated cell dose was 6.4 (range, 2.5 - 73.8) x 107/kg. For these patients, Day-100 mortality from all causes was 25%. Primary graft failure occurred in 16%; 42% developed grades 2 - 4 acute graft-vs-host disease; and 19% developed grades 3-4 acute graft-vs-host disease. Data from published literature and from observational registries, institutional databases, and cord blood bank reviews reported to the docket for HPC, Cord Blood (from multiple cord blood banks) revealed nine cases of donor cell leukemia, one case of transmission of infection, and one report of transplantation from a donor with an inheritable genetic disorder. The data are not sufficient to support reliable estimates of the incidences of these events. In a study of 364 patients, 15% of the patients developed engraftment syndrome.

Pregnancy: Based on animal data, may cause fetal harm. Use only if clearly needed. (8.1)

Pregnancy Category C. Animal reproduction studies have not been conducted with HPC, Cord Blood. It is also not known whether HPC, Cord Blood can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. There are no adequate and well-controlled studies in pregnant women. HPC, Cord Blood should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.

HPC, Cord Blood has been used in pediatric patients with disorders affecting the hematopoietic system that are inherited, acquired, or resulted from myeloablative treatment. [See Dosage and Administration (2), Adverse Reactions (6), and Clinical Studies (14)]

Clinical studies of HPC, Cord Blood (from multiple cord blood banks) did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently than younger subjects. In general, administration of HPC, Cord Blood to patients over age 65 should be cautious, reflecting their greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.

HPC, Cord Blood contains Dextran 40 which is eliminated by the kidneys. The safety of HPC, Cord Blood has not been established in patients with renal insufficiency or renal failure.

There has been no experience with overdosage of HPC, Cord Blood in human clinical trials. Single doses of HPC, Cord Blood from ClinImmune Labs up to 6.5 x 108 TNC/kg have been administered. HPC, Cord Blood prepared for infusion may contain dimethyl sulfoxide (DMSO). The maximum tolerated dose of DMSO has not been established, but it is customary not to exceed a DMSO dose of 1 gm/kg/day when given intravenously. Several cases of altered mental status and coma have been reported with higher doses of DMSO.

For DMSO overdosage, general supportive care is indicated. The role of other interventions to treat DMSO overdosage has not been established.

HPC, Cord Blood consists of hematopoietic progenitor cells, monocytes, lymphocytes, and granulocytes from human cord blood. Blood recovered from umbilical cord and placenta is volume reduced and partially depleted of red blood cells and plasma. The active ingredient is hematopoietic progenitor cells which express the cell surface marker CD34. The potency of cord blood is determined by measuring the numbers of total nucleated cells (TNC) and CD34+ cells, and cell viability. Each unit of HPC, Cord Blood contains a minimum of 5 x 108 total nucleated cells with at least 1.25 x 106 viable CD34+ cells at the time of cryopreservation. The cellular composition of HPC, Cord Blood depends on the composition of cells in the blood recovered from the umbilical cord and placenta of the donor. The actual nucleated cell count, the CD34+ cell count, the ABO group, and the HLA typing are listed on the container label and/or accompanying records sent with each individual unit. HPC, Cord Blood has the following inactive ingredients: dimethyl sulfoxide (DMSO) and Dextran 40. When prepared for infusion according to instructions, the infusate contains the following inactive ingredients: Dextran 40, human serum albumin, and residual DMSO.

Hematopoietic stem/progenitor cells from HPC, Cord Blood migrate to the bone marrow where they divide and mature. The mature cells are released into the bloodstream, where some circulate and others migrate to tissue sites, partially or fully restoring blood counts and function, including immune function, of blood-borne cells of marrow origin. [See Clinical Studies (14)] In patients with enzymatic abnormalities due to certain severe types of storage disorders, mature leukocytes resulting from HPC, Cord Blood transplantation may synthesize enzymes that may be able to circulate and improve cellular functions of some native tissues. However, the precise mechanism of action is unknown.

The effectiveness of HPC, Cord Blood, as defined by hematopoietic reconstitution, was demonstrated in one single-arm prospective study and in retrospective reviews of data from an observational database for HPC, Cord Blood and data in the dockets and public information. Sixty-six percent (n=862) of the 1299 patients in the docket and public data underwent transplantation as treatment for hematologic malignancy. Results for patients who received a total nucleated cell dose ≥2.5 x 10⁷/kg are shown in Table 2. Neutrophil recovery is defined as the time from transplantation to an absolute neutrophil count more than 500 per microliter. Platelet recovery is the time to a platelet count more than 20,000 per microliter. Erythrocyte recovery is the time to a reticulocyte count greater than 30,000 per microliter. The total nucleated cell dose and degree of HLA mismatch were inversely associated with the time to neutrophil recovery in the docket data.

3 VERIFICATION OF PRODUCT IDENTITY HPC, Cord Blood is shipped frozen in an overwrap in the metal canister. HPC, Cord Blood must be kept at or below -150° C, either inside the container used for shipping (Dry-Shipper) or in vapor phase of a Liquid Nitrogen (LN₂) storage device at the Transplant Center (recommended). Check the HPC, Cord Blood identification number (ID) on the label to confirm its identity with the ID of the expected product as soon as it is received (Figure 1). Figure 1 Wearing protective cryogloves, transfer the HPC, Cord Blood from the Dry-Shipper to the vapor phase of a LN₂ storage tank. Carefully open the canister while it is in the vapor of the freezer to prevent the bag from cracking and the yellow port covers from popping off (Figure 2). Figure 2 Work carefully to avoid damaging the frozen plastic product bag. Check the bar-coded label on the product against your records to verify that the bar code and visually-readable printed number absolutely conforms to the information previously provided and the documentation included with the HPC, Cord Blood product (Form E6.251 - Human Cord Blood Unit Receipt Form).

NOTE:

If there is any error or ambiguity with regard to the product ID, close the canister and keep the product at LN2 temperature. Immediately advise the staff of ClinImmune Labs, UCCBB and the transplant physician. Do not proceed until the problem is resolved. If your LN2 storage tanks have no space to store the product in its canister, add LN2 to the UCCBB dry-shipper to maintain the product frozen until a completely satisfactory determination is made.

4 METHOD 4.1 Preparation of Water Bath A water bath with minimum 2 L capacity is recommended. Clean water bath with 70% isopropyl alcohol and fill with appropriate volume of sterile water. Maintain the temperature of the water bath between 36-38°C prior to thawing the HPC, Cord Blood. 4.2 Preparation of Wash Media Prepare wash media no sooner than one hour prior to the thaw for infusion. Media expires 4 hours after preparation. Determine the total volume of media needed. For reconstitution only, use an equal volume of media to the total HPC, Cord Blood cryo volume. For wash and reconstitution, use twice the total HPC, Cord Blood cryo volume.
Example:        50 mL of HPC, Cord Blood cryo volume
                         For reconstitution only: 50 mL of media are needed.
                         For reconstitution and wash: 100 mL of media are needed. Prepare the media by mixing equal amounts of 5% albumin and 10% Dextran 40.
Example: To prepare 50 mL of media, mix 25 mL of 5% albumin and 25 mL of 10% Dextran 40. 4.3 Thawing HPC, Cord Blood Carefully cut and remove the overwrap (Figures 3, 4, and 5). Figure 3 Figure 4 Figure 5 Put the HPC, Cord Blood into a sterile centrifuge bag and place HPC, Cord Blood in the water bath. If there are two cryo bags for the same HPC, Cord Blood, thaw both bags in separate sterile centrifuge bags at the same time. Thaw the HPC, Cord Blood until all frozen portions dissolve into solution. Take the bag(s) out of the water bath, remove the HPC, Cord Blood from the sterile bag(s), and place it into a laminar flow hood. To access a bag with a configuration as shown in Figures 6 and 7, remove the yellow port protector and insert a plasma transfer set into the port. For a bag with configuration as shown in Figure 8, open the port by twisting the upper part of the port. Measure the volume by syringe or weight as per transplant center procedures. Remove a small volume for quality control (QC) testing as per transplant center procedures. If the HPC, Cord Blood has two cryo bags, pool both portions together in the same transfer bag before removing the sample. Figure 6 Figure 7 Figure 8 The thawed HPC, Cord Blood is ready for reconstitution or washing (see below). 4.4 Reconstituting and Washing HPC, Cord Blood For reconstituting HPC, Cord Blood (dilution) If using a 150 mL double transfer pack, clamp off one of the bags with a plastic clip and drain the HPC, Cord Blood into the open transfer bag (Figure 9). Figure 9 For two cryo bags, drain both bags into the double transfer bag or use a 300 mL transfer bag. Use a hemostat to clamp the line to the transfer bag containing the HPC, Cord Blood. Wash the cryo bag by injecting the wash media (equal to the total volume of the frozen HPC, Cord Blood) into the empty bag and rinsing thoroughly (Figure 10). Figure 10 Open the hemostat and slowly drain the wash media into the bag with the HPC, Cord Blood while gently mixing the cells in the bag with a rocking motion. Seal off the empty freezing bag. Remove a small volume of the reconstituted product for QC testing (such as complete blood count (CBC), CFU, CD34+ counts, viability, and sterility) as per transplant center procedures. Allow five minutes for the cells to equilibrate. HPC, Cord Blood is ready for infusion or for washing out the cryoprotectant. The recommended expiration time is four hours at 1-8°C from the time of thaw. For removing cryoprotectant (washing) Centrifuge the diluted HPC, Cord Blood (with ports up) at 1300 rpm (473 x g) for ten minutes at 1-6°C. Remove the supernatant (equal volume of added wash media) using a plasma extractor (Figure 11). Figure 11 Slowly add the remaining washing media (that was not used in reconstitution). Mix the bag gently. Remove a small volume of the reconstituted product for QC testing (such as CBC, CFU, CD34+ counts, viability, and sterility) as per transplant center procedures.
