LANTIDRA consists of a suspension of allogeneic pancreatic islets in buffered transplant medium containing sodium chloride, dextrose, minerals, amino acids, vitamins, and other compounds supplemented with HEPES (2-[4-(2-hydroxyethyl)piperazin-1-yl] ethanesulfonic acid; 10 mM final concentration) and human serum albumin (0.5% final concentration).
The active ingredient in LANTIDRA is allogeneic islets of Langerhans derived from a donor pancreas. Islets contain several types of endocrine (hormone-secreting) cells, including β-, α-, pancreatic peptide- (PP-), δ-, and ε-cells.
Each single-donor islet batch consists of two infusion bags connected to each other via a sterile connector. One LANTIDRA bag containing up to a maximum of 1 x 106 EIN in 400 ml of transplant media, and the second Rinse Bag containing 200 ml transplant media used to rinse the LANTIDRA bag and the infusion line.

LANTIDRA is an allogeneic pancreatic islet cellular therapy indicated for the treatment of adults with Type 1 diabetes who are unable to approach target HbA1c because of current repeated episodes of severe hypoglycemia despite intensive diabetes management and education. Use LANTIDRA in conjunction with concomitant immunosuppression.
When considering the risks associated with the infusion procedure and long-term immunosuppression, there is no evidence to show a benefit of administration of LANTIDRA in patients whose diabetes is wellcontrolled with insulin therapy or patients with hypoglycemic unawareness who are able to prevent current repeated severe hypoglycemic events (neuroglycopenia requiring active intervention from a third party) using intensive diabetes management (including insulin, devices, and education).
Repeated intraportal islet infusions are not recommended in patients who have experienced prior portal thrombosis, unless the thrombosis was limited to second- or third-order portal vein branches.
There is no evidence to support the safe and effective use of LANTIDRA in patients with liver disease, renal failure, or who have received a renal transplant.
For infusion into the hepatic portal vein only.
The recommended minimum dose is 5,000 EIN/kg for initial infusion and 4,500 EIN/kg for subsequent infusion in the same recipient. The maximum dose per infusion is dictated by the estimated tissue volume, which should not exceed 10 cc per infusion, and the total EIN present in the infusion bag (up to a maximum of 1 x 106 EIN per bag).
A second infusion may be performed if the patient does not achieve independence from exogenous insulin within one year of infusion or within one year after losing independence from exogenous insulin after a previous infusion. A third infusion may be performed using the same criteria as for the second infusion. There are no data regarding the effectiveness or safety for patients receiving more than three infusions.
Provide pre-procedural induction immunosuppression 30 – 360 minutes prior to LANTIDRA infusion. Include the following, at the discretion of the treating physician who is experienced with management of immunosuppression regimens for islet cell transplantation:
Failure to follow these directions may result in damage and decreased viability of the islets.
Do not administer with leukodepleting filters.
Note
If there are any product irregularities present or if the container appears damaged or otherwise compromised, do not infuse product and immediately notify the transplant physician/team and CellTrans at 1-800-500-1617
Immunosuppression
Continue immunosuppression permanently to prevent islet graft rejection. [See WARNINGS AND PRECAUTIONS]. (See Section 5.1 for reasons to discontinue immunosuppression.)
Avoid systemic steroids. Use a combination of a calcineurin inhibitor and an mTOR inhibitor or appropriate alternatives, at the discretion of the physician. Monitor trough levels of maintenance immunosuppressant drugs, and adjust the dose to maintain appropriate blood levels.
LANTIDRA is a cellular suspension of allogeneic pancreatic islets (islets of Langerhans) in buffered transplant media containing sodium chloride, dextrose, minerals, amino acids, vitamins, and other compounds supplemented with HEPES (2-[4-(2-hydroxyethyl)piperazin-1-yl] ethanesulfonic acid; 10 mM final concentration) and human serum albumin (0.5% final concentration).
Each infusion uses one lot of LANTIDRA which consists of islets manufactured from the pancreas of a single deceased donor. Each dose of LANTIDRA is provided as two (2) infusion bags connected to each other via sterile connector. One bag contains LANTIDRA up to a maximum of 1 x 106 EIN in 400 ml of transplant media and the second bag (Rinse Bag) contains transplant media used to rinse the LANTIDRA bag and the infusion line.
The dosage strength is represented by the total EIN in a single preparation and varies between product batches. Dosage strength information for an individual batch is provided on the container label and in accompanying documentation (Final Islet Product Certificate of Analysis).

Ninety percent (90%) of subjects had at least one serious adverse reaction. The major causes were attributed to:
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 LANTIDRA in subjects with type 1 diabetes and hypoglycemic unawareness was demonstrated in two clinical trials (Study 1, Study 2) involving a total of 30 subjects who received between one and three doses of LANTIDRA. Duration between first and second transplant was one month to 2.8 years and between second and third dose from 3 months to 7.8 years (See Figure 1). Because of the variable duration of follow-up, number of infusions, and interval between infusions, adverse reactions were reported for the total duration for which each subject was followed. [Clinical Studies] Subjects were followed for 0.3 to 14.5 years (mean 3 ± 3.7 years) after the first infusion.
Serious reactions were reported in 27 (90%) of subjects. There were two (7%) deaths; one death from multiorgan failure with sepsis (1.6 years after the first infusion), and one from progressive confusion, global atrophy and micro-ischemic disease (9.7 years after the first infusion). Both subjects were using immunosuppression at the time of the event. Additionally, 8 (27%) subjects experienced at least one lifethreatening adverse reaction and 26 (87%) subjects experienced at least one severe reaction before their last follow-up.
Risks of common community-acquired infections and opportunistic infections increases with immunosuppression. In total, 211 infections were reported for 26 subjects; one was life-threatening, 22 reactions severe, and 115 events moderate in severity. Additionally, one subject died of multi-organ failure from sepsis in the second year after infusion.
Discontinuation of immunosuppression resulted in loss of islet cell function and if achieved insulin independence. This was described for 8 (27%) subjects.
Malignancy risk is known to increase with immunosuppression. In total, 16 adverse reactions of malignancy were reported in 11 subjects; three malignancies were life-threatening. The malignancies included 12 skin cancers, and one post-transplant lymphoproliferative disease, one breast cancer, and one thyroid cancer. Anemia was reported in 24 (80%) of subjects. Of the 90 adverse reactions reported, one reaction was lifethreatening (Hgb <6.5gm/dL), 9 reactions were severe (<8-6.5 gm/dL), and 27 reactions were moderate in severity (<10-8 gm/dL).
Anemia was attributed to bleeding because of procedural complications as well as immunosuppression. Transfusion was required for severe and life-threatening reactions. Overall, five transfusions were administered to five subjects. Three transfusions were for procedural related complications and two were non-procedure related. Alterations in red blood cell turnover and transfusion can alter the accuracy of HbA1c measurements. Therefore, in addition to monitoring for the development of anemia as a result of immunosuppression or a result of a procedural complications, healthcare providers should consider the occurrence of anemia in the interpretation and use of HbA1c in the management of patients with type 1 diabetes who have received LANTIDRA.
Serious reactions related to the 56 infusion procedures included one life-threatening liver laceration, one intraabdominal hemorrhage, and two perihepatic hematomata resulting in prolonged hospitalization. Manage hemostasis in the catheter track using standard practices following infusion of LANTIDRA to reduce the risk of bleeding.
Elevation in portal blood pressure may occur following intraportal islet infusion but is usually temporary. During clinical trials with LANTIDRA, the median peak portal blood pressure increase from baseline was 3 mmHg (range -3 to 18 mmHg). Elevated portal pressures ≥ 22 mmHg were reported during procedures for two subjects requiring cessation of the procedure, and incomplete delivery of LANTIDRA for one subject. Monitor portal pressure and halt islet infusion if portal pressure rises above 22 mmHg.
Of the 30 subjects who received LANTIDRA, 28 subjects had panel reactive antibody (PRA) data. Overall, 6 of 28 (21%) had a transition from baseline Class I PRA < 20% to ≥ 20% after infusion. These included 1 of 9 (11%) who received one infusion, 3 of 12 (25%) who received two infusions, and 2 of 7 (29%) who received three infusions.

Concomitant use of immunosuppression is required to maintain islet cell viability. The use of immunosuppression in patients receiving LANTIDRA increases the risk of serious and potentially fatal adverse reactions. [ADVERSE REACTIONS]
Patients receiving immunosuppressants are at increased risk of:
Liver laceration, hemorrhage and intra-abdominal bleeding have occurred with portal administration of LANTIDRA. Manage hemostasis in the catheter track using standard practices following infusion of LANTIDRA to reduce the risk of bleeding. Monitor for bleeding clinically and with laboratory assessments. Blood transfusions have been required.
Elevation in portal blood pressure has occurred during and following intraportal islet infusion [ADVERSE REACTIONS]. Monitor portal pressure; pause infusion if portal pressure rises above 22 mmHg and do not resume until it falls below 18 mmHg. Terminate infusion if portal pressure remains above 22 mmHg for longer than 10 minutes. [DOSAGE AND ADMINISTRATION]
Portal vein branch thrombosis may occur following infusion of LANTIDRA. Repeated intraportal islet infusions are not recommended in patients who have experienced prior portal thrombosis unless the thrombosis was limited to second- or third-order portal vein branches. [Limitations Of Use]
Patients with a positive T- and B-cell crossmatch between recipient serum and donor lymphocytes may immediately reject the islet cells. The T- and B-cell crossmatch assay is binary. T- and B-cell both need to be negative.
There is a risk of communicable disease transmission from donor to recipient that exists for LANTIDRA. Monitor patients for signs of active infection following LANTIDRA infusion and treat appropriately if infection is suspected.
Product administration may elevate PRA and negatively impact candidacy for renal transplant. Consider benefit-risk of administering LANTIDRA to a patient who may require a renal transplant in the future.
Advise the patient to read the FDA-approved patient labeling (PATIENT INFORMATION).
Procedural Risks
Pregnancy
Lactation
If the immunosuppressive drugs have the potential to affect the ability of the patient to breast feed, inform the patient that breast feeding would be discontinued prior to starting the pre-procedural medications needed for administration of LANTIDRA.
Fertility
Inform patients that treatment with immunosuppression drugs may impair fertility and the ability to achieve pregnancy in the future.
Inform patients that administration of LANTIDRA has been associated with the development of panel reactive antibodies (PRA). PRA can adversely affect the ability to achieve a donor match for those patients who require kidney transplant.
After infusion of LANTIDRA, discuss the following:
In preparation for discharge after the procedure and at appropriate follow up appointments, repeat the information for immunosuppression, diabetes management, reproductive considerations (pregnancy, lactation, and fertility).
Pregnancy risk has not been assessed for LANTIDRA. No animal reproductive and development toxicity studies have been conducted with LANTIDRA. However, there is a risk of fetal malformations associated with certain immunosuppression medications that may be used following LANTIDRA administration. Additionally, the risks to the patient and fetus from the procedure for LANTIDRA infusion in pregnant women has not been assessed.
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.
The risk of exposing a child to LANTIDRA components during breastfeeding has not been assessed. However, some required concomitant medications, including immunosuppressants, may be excreted in milk at least in trace amounts. Because of this, a decision should be made about whether to discontinue breastfeeding in patients who will receive a LANTIDRA infusion.
Due to the risk of fetal malformations associated with required concomitant medications, including immunosuppressants, females of reproductive potential should have a confirmed negative pregnancy test prior to LANTIDRA infusion.
Female patients of reproductive potential should be counselled to contact their transplant team immediately if they become pregnant.
Because long-term immunosuppression is required following LANTIDRA administration, women of childbearing potential should be informed of the potential risks that these medications pose during pregnancy and should be told to use effective contraception prior to initiation of immunosuppression and thereafter for as long as they retain reproductive potential.
Male and female fertility may be compromised by certain medications used for maintenance immunosuppression following LANTIDRA administration.
For male patients, review the concomitant medications and determine if there is a potential for production of abnormal sperm.
The safety and effectiveness of LANTIDRA have not been established in pediatric patients with type 1 diabetes.
The safety and effectiveness of LANTIDRA have not been established in geriatric patients with type 1 diabetes and hypoglycemic unawareness. Clinical studies of LANTIDRA did not include sufficient numbers of patients aged 65 and over to determine whether they respond differently than younger patients.
No Information Provided
Do not administer LANTIDRA to patients who have concomitant diseases or conditions, including pregnancy, that contraindicate the procedure for LANTIDRA infusion or immunosuppression.
Pancreatic islets regulate blood glucose levels through secretion of multiple hormones in response to increases and decreases in blood glucose. Endocrine cells within pancreatic islets release insulin, glucagon, somatostatin, pancreatic peptide, and ghrelin. Insulin stimulates glucose uptake by peripheral tissues; glucagon mobilizes glucose from the liver into circulation; somatostatin inhibits both α- and β-cell secretions; pancreatic peptide inhibits pancreatic exocrine secretion; and ghrelin inhibits insulin secretion. The primary mechanism of action of LANTIDRA is believed to be secretion of insulin by infused (transplanted) β- cells.
The pharmacodynamic effects of LANTIDRA are a result of hormones, especially insulin, that are secreted by the infused (transplanted) islets in response to fluctuations in blood glucose levels.
Basal and stimulated blood glucose were determined at baseline and at 1 year following a subject’s last transplant during Study 1 and Study 2 using a mixed meal tolerance test (MMTT). Combined results from these studies are summarized in Table 2. [Clinical Studies]
The pharmacodynamic profile of the allogeneic islet cells is most clearly demonstrated in subjects who are free from the requirement of exogenous insulin.

The effectiveness of LANTIDRA in subjects with type 1 diabetes and hypoglycemic unawareness was demonstrated in 2 clinical trials (Study 1, Study 2) involving a combined 30 subjects, all of whom received at least one islet infusion and a maximum of 3 infusions. Both trials were prospective, open-label, single-arm studies.
Subject demographics: median age 46.5 (range: 21 – 67) years, 80% female, 100% white, 97% non- Hispanic.
Subjects received a median islet number of 399,178 EIN (range 253,924 EIN to 858,856 EIN) per infusion. Subjects received a median islet dose of 6,570 EIN/kg (range 4,186 EIN/kg to 13,633 EIN/kg) per infusion. Thirty subjects participated in the combined Study 1 and Study 2, with 11 subjects receiving one infusion, 12 subjects receiving two infusions, and 7 subjects receiving three infusions. Of the 19 subjects who received a second infusion, 6 were insulin-independent at the time of their second infusion. Of the 11 subjects who did not receive a second infusion, 4 were insulin-independent, 3 did not have a donor, and 4 were intolerant to immunosuppression or withdrew from the study within 6 months. All 7 subjects who received a third infusion were insulin-dependent. One subject was not able to get a third infusion because of infection. No subject was unable to receive a third infusion because of lack of a donor or intolerance to immunosuppression.
Concomitant study medications were provided as described in Table 3:

A glucagon-like peptide-1 (GLP-1) agonist (e.g., exenatide 5 mcg subcutaneously within 60 minutes before infusion), was administered and was supposed to be continued (5 mcg BID), for up to 6 months after transplant. Exenatide was not given to the first 4 subjects in Study 1, and 11 of the remaining 26 subjects used exenatide less than the per protocol 6-months post-transplant because of adverse reactions. Because of the variability of exenatide use in the clinical studies, there are insufficient data to support exenatide use in patients receiving LANTIDRA.
Insulin independence, defined as not requiring exogenous insulin to achieve adequate glycemic control, was also determined. Results are summarized in Table 4.
Table 4: Achievement and Maintenance of Glycemic Control following LANTIDRA Infusion (Studies Study 1 and Study 2)
| Total Duration Insulin Independent (years) | N | Mean | Std Dev | Min | Max |
| Study 1 | 10 | 5.1 | 4.2 | 0.2 | 12.8 |
| Study 2 | 20 | 3.2 | 3.1 | 0 | 9.9 |
Five subjects had no days of insulin independence. For the 25 subjects who achieved insulin independence, 4 subjects (13.3%) were insulin independent for less than one year, 12 subjects (36.7%) for 1 to 5 years, and 9 subjects (33.3%) for greater than 5 years.

LANTIDRA
(donislecel-jujn)
Allogeneic Pancreatic Islet Cellular Suspension for Hepatic Portal Vein Infusion
Read this patient information before you start treatment with LANTIDRA. There may be new information.
This information does not take the place of talking with your healthcare provider about your medical condition, your treatment options or the potential benefits and risks of treatment with LANTIDRA.
What is the most important information I should know about LANTIDRA?
LANTIDRA is only for adult patients with Type 1 diabetes who have repeated episodes of severe low blood glucose, those that they need help from someone to treat, and cannot get their HbA1c at the goal set by their endocrinologist and diabetes team, despite intensive diabetes management and education.
LANTIDRA is a cell therapy that is infused (transplanted) into your liver. Talk to your transplant doctor or endocrinologist about your risks from the infusion procedure and the long-term immune suppression medicine that you will need to use after you get the infusion.
Risks from the infusion can include
You will need to take medicines that suppress your immune system regularly for your transplant to survive.
Risks of long-term immune suppression are increased risk of infection, including serious infection, organ failure, and death, and increased risk of certain cancers, including skin and lymph node cancer (lymphoma). Regular follow up appointments are needed.
Call your doctor right away if you have any symptoms of an infection, including:
Follow instructions for regular skin exams and notify your endocrinologist and transplant team if you are told you have skin cancer.
You will need to continue to take insulin and check your blood glucose (sugar) as instructed by your endocrinologist and transplant team.
Insulin independence is not immediate and can take several weeks to occur. Following treatment with LANTIDRA, not every patient becomes insulin independent and some patients who become insulin independent may need to restart insulin.
Monitor your blood glucose levels after getting LANTIDRA. Not all patients are able to stop taking insulin after getting the infusion. Do not stop taking insulin without talking to your doctor. It is very important to follow your doctor’s instructions for blood glucose monitoring and keep your follow-up appointments to decrease the chance of serious and life-threatening high glucose or diabetic ketoacidosis.
What is LANTIDRA?
LANTIDRA is an islet cell therapy that is for people with Type 1 Diabetes. Islet cells come from the pancreas of a deceased organ donor.
Pancreatic islet cells include cells, called beta cells, that make insulin. In some people with Type 1 Diabetes, the infused beta cells can make enough insulin to allow the diabetic to control blood glucose without taking insulin.
Who should not take LANTIDRA?
LANTIDRA requires continuing use of medicines that suppress your immune system. Do not get the infusion if you cannot have these medicines because the islet cells will not survive.
Do not get LANTIDRA if you are pregnant or want to become pregnant. Immune suppression medicines can cause serious harm, including death, to you and your developing baby.
If you are male and have a female partner who can become or desires pregnancy, you should ask your transplant team if your immunosuppression drugs can cause abnormal sperm. If your immunosuppression drugs can cause abnormal sperm, advise your female partner to discuss the potential increased risks to her and the developing baby/infant with her healthcare provider.
How will I get LANTIDRA?
LANTIDRA islet cells are infused into your liver through a catheter that is placed into a large blood vessel going into your liver (called the hepatic portal vein). This is done under anesthesia. You will need to stay in the hospital for at least 24 hours.
Before getting LANTIDRA, you will need to start the immune suppression medicine. You will need to continue this medicine after the infusion to keep the islet cells alive.
What should I avoid when I get LANTIDRA?
Because immune suppression can increase your risk of infection, it is important that you:
You can ask your transplant team if there are additional things you should avoid because of your specific immune suppression drugs.
What are the possible or reasonably likely side effects of LANTIDRA?
Injury can occur during the delivery of LANTIDRA into the large blood vessel going to your liver (the hepatic portal vein).
You have a higher risk of infections and cancer because of the immune suppression needed to keep the islet cells alive. In some cases, the immune suppression will be stopped because of these side effects and the islet cells will die and stop making insulin.
You can make antibodies from your islet cell infusion that can make it harder to get a match for transplants, such as a kidney transplant.
You can ask your doctor for information about LANTIDRA that is written for health professionals. Call your doctor about any side effects that concern you.
What should I tell my endocrinologist and transplant physician before receiving LANTIDRA?
For your LANTIDRA (islet cells) to survive, you must strictly follow the instructions for your immune suppression medicines. If you have any questions or problems about taking these medicines, ask your endocrinologist or transplant doctor for help.
If you can become pregnant, you should use effective birth control after getting LANTIDRA. Talk with your doctor about the birth control regimens that may be right for you.
Some immunosuppressive drugs may cause formation of abnormal sperm. Ask your doctor if your immunosuppression drugs can cause abnormal sperm. If so, and you have a female partner who can become pregnant, you should discuss this with your partner and use effective birth control before starting treatment with immunosuppression drugs.
