"Outcomes for patients with advanced esophageal squamous cell carcinoma treated with chemotherapy alone remain poor, and there is a clear need for additional options beyond this long-standing standard of care," said Ian M. Waxman, M.D., development lead, gastrointestinal cancers, Bristol Myers Squibb. "The validation of our applications moves us a step closer to potentially bringing these two Opdivo-based regimens to patients in the EU who may benefit."

The applications are based on results from the pivotal Phase 3 CheckMate -648 trial, in which both Opdivo-based treatment combinations — Opdivo plus Yervoy and Opdivo plus chemotherapy — demonstrated a statistically significant and clinically meaningful overall survival (OS) benefit compared to chemotherapy at the pre-specified interim analysis in patients with unresectable advanced or metastatic esophageal squamous cell carcinoma (ESCC) with tumor cell PD-L1 expression ≥1%, as well as in the all-randomized population. Opdivo plus Yervoy is the first dual immunotherapy combination to demonstrate a superior survival benefit versus chemotherapy in this setting. The safety profiles of Opdivo and chemotherapy and of Opdivo plus Yervoy were consistent with the known safety profiles of the individual components.

Results from CheckMate -648 were presented in an oral session during the 2021 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting and were selected for the official ASCO (Free ASCO Whitepaper) press program.

Bristol Myers Squibb thanks the patients and investigators involved in the CheckMate -648 trial.

About CheckMate -648

CheckMate -648 is a randomized Phase 3 study evaluating Opdivo plus Yervoy or Opdivo plus fluorouracil and cisplatin against fluorouracil plus cisplatin alone in patients with unresectable advanced or metastatic esophageal squamous cell carcinoma. The primary endpoints of the trial are overall survival (OS) and progression-free survival (PFS) by blinded independent central review (BICR) in patients whose tumors express PD-L1 ≥1% for both Opdivo-based combinations versus chemotherapy. Secondary endpoints of the trial include OS and PFS by BICR in the all-randomized population.

In the Opdivo plus Yervoy arm, patients received treatment with Opdivo 3 mg/kg every 2 weeks and Yervoy 1 mg/kg every 6 weeks up to 24 months or until disease progression or unacceptable toxicity. In the Opdivo plus chemotherapy arm, patients received treatment with Opdivo 240 mg on Day 1 and Day 15, fluorouracil 800 mg/m²/day on Day 1 through Day 5 (for 5 days), and cisplatin 80 mg/m² on Day 1 of four-week cycle. Patients received Opdivo for up to 24 months or until disease progression or unacceptable toxicity, and chemotherapy until disease progression or unacceptable toxicity.

About Esophageal Cancer

Esophageal cancer is the eighth most common cancer and the sixth leading cause of death from cancer worldwide, with approximately 600,000 new cases and over 540,000 deaths in 2020. The two most common types of esophageal cancer are squamous cell carcinoma and adenocarcinoma, which account for approximately 85% and 15% of all esophageal cancers, respectively, though esophageal tumor histology can vary by region with the highest rate of esophageal squamous cell carcinoma occurring in Asia (~95%), Europe (~65%) and North America (35%).

About Opdivo

Opdivo is a programmed death-1 (PD-1) immune checkpoint inhibitor that is designed to uniquely harness the body’s own immune system to help restore anti-tumor immune response. By harnessing the body’s own immune system to fight cancer, Opdivo has become an important treatment option across multiple cancers.

Opdivo’s leading global development program is based on Bristol Myers Squibb’s scientific expertise in the field of Immuno-Oncology and includes a broad range of clinical trials across all phases, including Phase 3, in a variety of tumor types. To date, the Opdivo clinical development program has treated more than 35,000 patients. The Opdivo trials have contributed to gaining a deeper understanding of the potential role of biomarkers in patient care, particularly regarding how patients may benefit from Opdivo across the continuum of PD-L1 expression.

In July 2014, Opdivo was the first PD-1 immune checkpoint inhibitor to receive regulatory approval anywhere in the world. Opdivo is currently approved in more than 65 countries, including the United States, the European Union, Japan and China. In October 2015, the Company’s Opdivo and Yervoy combination regimen was the first Immuno-Oncology combination to receive regulatory approval for the treatment of metastatic melanoma and is currently approved in more than 50 countries, including the United States and the European Union.

About Yervoy

Yervoy is a recombinant, human monoclonal antibody that binds to the cytotoxic T-lymphocyte-associated antigen-4 (CTLA-4). CTLA-4 is a negative regulator of T-cell activity. Yervoy binds to CTLA-4 and blocks the interaction of CTLA-4 with its ligands, CD80/CD86. Blockade of CTLA-4 has been shown to augment T-cell activation and proliferation, including the activation and proliferation of tumor infiltrating T-effector cells. Inhibition of CTLA-4 signaling can also reduce T-regulatory cell function, which may contribute to a general increase in T-cell responsiveness, including the anti-tumor immune response. On March 25, 2011, the U.S. Food and Drug Administration (FDA) approved Yervoy 3 mg/kg monotherapy for patients with unresectable or metastatic melanoma. Yervoy is approved for unresectable or metastatic melanoma in more than 50 countries. There is a broad, ongoing development program in place for Yervoy spanning multiple tumor types.

IMPORTANT SAFETY INFORMATION

Severe and Fatal Immune-Mediated Adverse Reactions

Immune-mediated adverse reactions listed herein may not include all possible severe and fatal immune-mediated adverse reactions.

Immune-mediated adverse reactions, which may be severe or fatal, can occur in any organ system or tissue. While immune-mediated adverse reactions usually manifest during treatment, they can also occur after discontinuation of OPDIVO or YERVOY. Early identification and management are essential to ensure safe use of OPDIVO and YERVOY. Monitor for signs and symptoms that may be clinical manifestations of underlying immune-mediated adverse reactions. Evaluate clinical chemistries including liver enzymes, creatinine, adrenocorticotropic hormone (ACTH) level, and thyroid function at baseline and periodically during treatment with OPDIVO and before each dose of YERVOY. In cases of suspected immune-mediated adverse reactions, initiate appropriate workup to exclude alternative etiologies, including infection. Institute medical management promptly, including specialty consultation as appropriate.

Withhold or permanently discontinue OPDIVO and YERVOY depending on severity (please see section 2 Dosage and Administration in the accompanying Full Prescribing Information). In general, if OPDIVO or YERVOY interruption or discontinuation is required, administer systemic corticosteroid therapy (1 to 2 mg/kg/day prednisone or equivalent) until improvement to Grade 1 or less. Upon improvement to Grade 1 or less, initiate corticosteroid taper and continue to taper over at least 1 month. Consider administration of other systemic immunosuppressants in patients whose immune-mediated adverse reactions are not controlled with corticosteroid therapy. Toxicity management guidelines for adverse reactions that do not necessarily require systemic steroids (e.g., endocrinopathies and dermatologic reactions) are discussed below.

Immune-Mediated Pneumonitis

OPDIVO and YERVOY can cause immune-mediated pneumonitis. The incidence of pneumonitis is higher in patients who have received prior thoracic radiation.

OPDIVO in combination with cabozantinib can cause hepatic toxicity with higher frequencies of Grade 3 and 4 ALT and AST elevations compared to OPDIVO alone. Consider more frequent monitoring of liver enzymes as compared to when the drugs are administered as single agents. In patients receiving OPDIVO and cabozantinib, Grades 3 and 4 increased ALT or AST were seen in 11% of patients.

Immune-Mediated Endocrinopathies

OPDIVO and YERVOY can cause primary or secondary adrenal insufficiency, immune-mediated hypophysitis, immune-mediated thyroid disorders, and Type 1 diabetes mellitus, which can present with diabetic ketoacidosis. Withhold OPDIVO and YERVOY depending on severity (please see section 2 Dosage and Administration in the accompanying Full Prescribing Information). For Grade 2 or higher adrenal insufficiency, initiate symptomatic treatment, including hormone replacement as clinically indicated. Hypophysitis can present with acute symptoms associated with mass effect such as headache, photophobia, or visual field defects. Hypophysitis can cause hypopituitarism; initiate hormone replacement as clinically indicated. Thyroiditis can present with or without endocrinopathy. Hypothyroidism can follow hyperthyroidism; initiate hormone replacement or medical management as clinically indicated. Monitor patients for hyperglycemia or other signs and symptoms of diabetes; initiate treatment with insulin as clinically indicated.

Severe or fatal cases have been reported for some of these adverse reactions: cardiac/vascular: myocarditis, pericarditis, vasculitis; nervous system: meningitis, encephalitis, myelitis and demyelination, myasthenic syndrome/myasthenia gravis (including exacerbation), Guillain-Barré syndrome, nerve paresis, autoimmune neuropathy; ocular: uveitis, iritis, and other ocular inflammatory toxicities can occur; gastrointestinal: pancreatitis to include increases in serum amylase and lipase levels, gastritis, duodenitis; musculoskeletal and connective tissue: myositis/polymyositis, rhabdomyolysis, and associated sequelae including renal failure, arthritis, polymyalgia rheumatica; endocrine: hypoparathyroidism; other (hematologic/immune): hemolytic anemia, aplastic anemia, hemophagocytic lymphohistiocytosis (HLH), systemic inflammatory response syndrome, histiocytic necrotizing lymphadenitis (Kikuchi lymphadenitis), sarcoidosis, immune thrombocytopenic purpura, solid organ transplant rejection.

In addition to the immune-mediated adverse reactions listed above, across clinical trials of YERVOY monotherapy or in combination with OPDIVO, the following clinically significant immune-mediated adverse reactions, some with fatal outcome, occurred in <1% of patients unless otherwise specified: nervous system: autoimmune neuropathy (2%), myasthenic syndrome/myasthenia gravis, motor dysfunction; cardiovascular: angiopathy, temporal arteritis; ocular: blepharitis, episcleritis, orbital myositis, scleritis; gastrointestinal: pancreatitis (1.3%); other (hematologic/immune): conjunctivitis, cytopenias (2.5%), eosinophilia (2.1%), erythema multiforme, hypersensitivity vasculitis, neurosensory hypoacusis, psoriasis.

Some ocular IMAR cases can be associated with retinal detachment. Various grades of visual impairment, including blindness, can occur. If uveitis occurs in combination with other immune-mediated adverse reactions, consider a Vogt-Koyanagi-Harada–like syndrome, which has been observed in patients receiving OPDIVO and YERVOY, as this may require treatment with systemic corticosteroids to reduce the risk of permanent vision loss.

Infusion-Related Reactions

OPDIVO and YERVOY can cause severe infusion-related reactions. Discontinue OPDIVO and YERVOY in patients with severe (Grade 3) or life-threatening (Grade 4) infusion-related reactions. Interrupt or slow the rate of infusion in patients with mild (Grade 1) or moderate (Grade 2) infusion-related reactions. In patients receiving OPDIVO monotherapy as a 60-minute infusion, infusion-related reactions occurred in 6.4% (127/1994) of patients. In a separate trial in which patients received OPDIVO monotherapy as a 60-minute infusion or a 30-minute infusion, infusion-related reactions occurred in 2.2% (8/368) and 2.7% (10/369) of patients, respectively. Additionally, 0.5% (2/368) and 1.4% (5/369) of patients, respectively, experienced adverse reactions within 48 hours of infusion that led to dose delay, permanent discontinuation or withholding of OPDIVO. In melanoma patients receiving OPDIVO 1 mg/kg with YERVOY 3 mg/kg every 3 weeks, infusion-related reactions occurred in 2.5% (10/407) of patients. In HCC patients receiving OPDIVO 1 mg/kg with YERVOY 3 mg/kg every 3 weeks, infusion-related reactions occurred in 8% (4/49) of patients. In RCC patients receiving OPDIVO 3 mg/kg with YERVOY 1 mg/kg, infusion-related reactions occurred in 5.1% (28/547) of patients. In MSI-H/dMMR mCRC patients receiving OPDIVO 3 mg/kg with YERVOY 1 mg/kg every 3 weeks, infusion-related reactions occurred in 4.2% (5/119) of patients. In MPM patients receiving OPDIVO 3 mg/kg every 2 weeks with YERVOY 1 mg/kg every 6 weeks, infusion-related reactions occurred in 12% (37/300) of patients.

Complications of Allogeneic Hematopoietic Stem Cell Transplantation

Fatal and other serious complications can occur in patients who receive allogeneic hematopoietic stem cell transplantation (HSCT) before or after being treated with OPDIVO or YERVOY. Transplant-related complications include hyperacute graft-versus-host-disease (GVHD), acute GVHD, chronic GVHD, hepatic veno-occlusive disease (VOD) after reduced intensity conditioning, and steroid-requiring febrile syndrome (without an identified infectious cause). These complications may occur despite intervening therapy between OPDIVO or YERVOY and allogeneic HSCT.

Follow patients closely for evidence of transplant-related complications and intervene promptly. Consider the benefit versus risks of treatment with OPDIVO and YERVOY prior to or after an allogeneic HSCT.

Embryo-Fetal Toxicity

Based on its mechanism of action and findings from animal studies, OPDIVO and YERVOY can cause fetal harm when administered to a pregnant woman. The effects of YERVOY are likely to be greater during the second and third trimesters of pregnancy. Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment with OPDIVO and YERVOY and for at least 5 months after the last dose.

Increased Mortality in Patients with Multiple Myeloma when OPDIVO is Added to a Thalidomide Analogue and Dexamethasone

In randomized clinical trials in patients with multiple myeloma, the addition of OPDIVO to a thalidomide analogue plus dexamethasone resulted in increased mortality. Treatment of patients with multiple myeloma with a PD-1 or PD-L1 blocking antibody in combination with a thalidomide analogue plus dexamethasone is not recommended outside of controlled clinical trials.

Lactation

There are no data on the presence of OPDIVO or YERVOY 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 and for 5 months after the last dose.

Serious Adverse Reactions

In Checkmate 037, serious adverse reactions occurred in 41% of patients receiving OPDIVO (n=268). Grade 3 and 4 adverse reactions occurred in 42% of patients receiving OPDIVO. The most frequent Grade 3 and 4 adverse drug reactions reported in 2% to <5% of patients receiving OPDIVO were abdominal pain, hyponatremia, increased aspartate aminotransferase, and increased lipase. In Checkmate 066, serious adverse reactions occurred in 36% of patients receiving OPDIVO (n=206). Grade 3 and 4 adverse reactions occurred in 41% of patients receiving OPDIVO.

The investigators concluded that the current clinical data of TST001 supports the initiation of the expansion phase study. Transcenta announced that the first patient of the Phase IIa clinical trial was successfully dosed on August 17, 2021.

Claudin 18.2 is a pan-cancer target and is highly expressed in gastric cancer, pancreatic cancer, gallbladder and biliary tract cancer, esophageal cancer and only highly expressed in normal gastric epithelial cells. The result of IMAB362 Phase II trial FAST validated Claudin18.2 as a novel target with high potential for anti-tumor efficacy. TST001 is a second-generation humanized antibody targeting Claudin18.2 developed by Transcenta in house, and it has higher affinity and more enhanced NK cells mediated ADCC activity than IMAB362.

Transcenta initiated a Phase I clinical trial of TST001 in the US and China in August 2020, led by Professor Lin Shen from Beijing Cancer Hospital, to evaluate its safety, tolerability, pharmacokinetics and preliminary efficacy. The Phase I single-agent dose escalation trial (0.3-10 mg/kg Q3W) has been completed in China. During the trial, a gastric cancer patient heavily pre-treated with therapies (including chemotherapies, PD-1 immunotherapy and anti-VEGF inhibitor) achieved partial response after 6 weeks of treatment with 6 mg/kg (Q3W) and the partial response was confirmed at 12 weeks post-treatment. TST001 also demonstrated a favorable safety profile with no additional drug-induced SAE other than nausea and vomiting. Recently, the US Food and Drug Administration (FDA) has granted Orphan Drug Designation to TST001 for the treatment of gastric cancer and gastroesophageal junction cancer.

The Phase IIa clinical trial of TST001 is an open-label, single-arm, multi-center study. It is designed to further evaluate the safety, tolerability, and anti-tumor efficacy in patients with multiple solid tumors expressing Claudin18.2 including gastric cancer. These patients will be screened using an immunohistochemistry assay developed by Transcenta and validated by central lab that specifically detects Claudin18.2 but not Claudin 18.1.

Professor Lin Shen from Beijing Cancer Hospital commented, "During the dose escalation phase of the TST001 trial, we have observed promising anti-tumor activity of TST001. TST001 is the second leading Claudin18.2-targeting monoclonal antibody worldwide following Zolbetuximab (IMAB362) of Astellas and is also the fastest-moving program in China. Now, we have gained experience on safety and preliminary efficacy on single agent and combination therapy. We look forward to advancing this program aggressively to bring more effective treatments to gastric cancer patients worldwide."

Dr. Michael Shi, EVP, Head of Global R&D and CMO of Transcenta said "When initiating TST001 project, we set very high differentiation criteria for binding affinity, in vitro and in vivo efficacy, antibody developability. Currently we have hit the goals in all aspects. This investigator meeting marks the official initiation of the multicenter Phase IIa clinical trial. We will work with many centers in China to further expand single-agent escalation / expansion studies and combination therapy to bring benefits to cancer patients around the world in the future."

About TST001

TST001 is the second Claudin18.2 targeting antibody therapeutic candidate being developed globally after Zolbetuximab (IMAB362). TST001 is a high-affinity recombinant humanized monoclonal antibody targeted Claudin18.2 generated by Transcenta’s Immune Tolerance Breaking Technology (IMTB) platform. TST001 can kill Claudin18.2 expressing tumor cells by mechanisms of antibody-dependent cellular cytotoxicity (ADCC) and complement-dependent cytotoxicity (CDC). Leveraging advanced bioprocessing technology, the fucose content of TST001 was significantly reduced during the production, which further enhanced the ADCC-mediated tumor killing activity of TST001. TST001 displayed more potent anti-tumor activities than IMAB362 analog in mouse xenograft experiments. Clinical trials for TST001 are ongoing in China and US since July 2020 (NCT04396821, NCT04495296/CTR20201281).

FDA Grants Accelerated Approval of JEMPERLI (dostarlimab-gxly) for dMMR Recurrent or Advanced Solid Tumors

On August 17, 2021 AnaptysBio, Inc. (Nasdaq: ANAB), a clinical-stage biotechnology company developing first-in-class antibody product candidates focused on emerging immune control mechanisms applicable to inflammation and immuno-oncology indications, reported that the U.S. Food and Drug Administration (FDA) approved a second indication for GSK’s JEMPERLI (dostarlimab-gxly) for the treatment of adult patients with mismatch repair deficient (dMMR) recurrent or advanced solid tumors, as determined by an FDA-approved test, that have progressed on or following prior treatment and who have no satisfactory alternative treatment options (Press release, AnaptysBio, AUG 17, 2021, View Source [SID1234586736]).

JEMPERLI was generated by AnaptysBio using its proprietary somatic hypermutation (SHM) antibody platform and subsequently developed by TESARO, Inc., now a part of GSK, under a collaboration agreement. Eight AnaptysBio-generated therapeutic antibodies have advanced into clinical development to date. JEMPERLI is the first AnaptysBio-generated antibody to obtain FDA approval, and this is the second indication for JEMPERLI to be approved by the FDA in 2021. This indication is approved under accelerated approval based on tumor response rate and durability of response. Continued approval for these indications may be contingent upon verification and description of clinical benefit in a confirmatory trial(s).

"We are pleased that JEMPERLI has been FDA-approved for a second indication and will be available to a broader cohort of solid tumor patients," said Hamza Suria, president and chief executive officer of AnaptysBio. "AnaptysBio’s capital-efficient business model is focused upon advancing our wholly-owned first-in-class antibodies to multiple clinical catalysts over the upcoming 18 months and is supported by milestone and royalty revenues under our GSK collaboration."

AnaptysBio has earned a $20 million milestone payment as a result of this second FDA approval for JEMPERLI in dMMR recurrent or advanced solid tumors. Earlier in 2021, AnaptysBio received a milestone payment of $10 million from GSK for acceptance of the BLA filing with the FDA for this second indication. AnaptysBio also received $20 million and $10 million milestone payments in April 2021 for FDA and European Medicines Agency (EMA) approvals of JEMPERLI for adult patients with a certain type of endometrial cancer, after having received a total of $15 million from GSK during 2020 for the FDA’s and EMA’s acceptances of these BLA and Marketing Authorisation Application (MAA) filings for JEMPERLI. We anticipate an additional $15 million and $165 million in milestone payments upon achievement of certain JEMPERLI regulatory and commercial milestones, respectively. Royalties due to AnaptysBio for JEMPERLI range from 8% to 25% of global net sales, where AnaptysBio will receive 8% of annual global net sales below $1 billion, and 12-25% of net sales above $1 billion. GSK has recently disclosed peak year annual sales estimates of £1-2 billion for JEMPERLI.1

JEMPERLI is also being developed by GSK for the treatment of other tumor types and treatment settings, including currently ongoing phase III trials in recurrent or primary advanced endometrial cancer in combination with chemotherapy standard of care (RUBY) and the phase III FIRST study of platinum-based therapy with JEMPERLI and niraparib versus standard of care platinum-based therapy as first-line treatment of stage III or IV non-mucinous epithelial ovarian cancer. In addition, JEMPERLI is being evaluated as monotherapy and in combination therapy across multiple tumor types and other cancers, including platinum-resistant ovarian cancer, non-small cell lung cancer, multiple myeloma and melanoma.

In the US, prevalence of dMMR across solid tumors has been estimated at 14%. Mismatch repair-deficient status is a biomarker that has been shown to predict response to immune checkpoint blockade with PD-1 therapy. Tumors with this biomarker are most commonly found in endometrial, colorectal and other gastrointestinal cancers, but may also be found in other solid tumors.

GSK continues to develop additional antibodies partnered with AnaptysBio, including cobolimab, an AnaptysBio-generated anti-TIM-3 antagonist antibody, and GSK4074386, an anti-LAG-3 antagonist antibody. Under the terms of the collaboration, AnaptysBio is due to receive development and regulatory milestone payments for each of the first two indications for each of these antibodies. AnaptysBio can potentially receive a total of $1.1 billion in aggregate milestone payments under this collaboration. In addition, AnaptysBio will receive royalties ranging from 4% to 8% on global net sales of cobolimab and GSK4074386 and 1% of GSK’s global net sales of ZejulaTM.

Lead author Hillard Lazarus, MD, FACP, Professor of Medicine at Case Western Reserve University and advisor to Partner Therapeutics, stated, "We can no longer view GM-CSF as a hematopoietic growth factor alone. These data suggest an emerging role for sargramostim immune suppressed sepsis, refractory bacterial and fungal infections, viral respiratory infections, autoimmune pulmonary alveolar proteinosis (aPAP), neurodegenerative diseases, and in combination with immune checkpoint inhibitors." GM-CSF has wide-ranging effects on diverse myeloid cells, including monocytes, macrophages and dendritic cells. It stimulates innate immune responses by activating macrophages and dendritic cells that prompt development of antigen-specific T cells and regulatory T cells, thereby linking innate and adaptive immune systems.

"This review article highlights Leukine’s potential to generate benefit for patients in numerous diseases that feature GM-CSF deficiency," said Edwin Rock, MD, PhD, Partner Therapeutics Chief Medical Officer.

LEUKINE (sargramostim) is a yeast-derived recombinant human granulocyte-macrophage colony stimulating factor (rhuGM-CSF) Leukine is approved by the U.S. Food and Drug Administration (FDA) and is also held by the U.S. government in the Strategic National Stockpile. Sargramostim has a different mechanism of action from recombinant G-CSFs products and data should not be extrapolated.

Leukine is indicated:

To shorten time to neutrophil recovery and to reduce the incidence of severe and life-threatening infections and infections resulting in death following induction chemotherapy in adult patients 55 years and older with acute myeloid leukemia (AML).
For the mobilization of hematopoietic progenitor cells into peripheral blood for collection by leukapheresis and autologous transplantation in adult patients.
For the acceleration of myeloid reconstitution following autologous bone marrow or peripheral blood progenitor cell transplantation in adult and pediatric patients two years of age and older.
For the acceleration of myeloid reconstitution following allogeneic bone marrow transplantation in adult and pediatric patients two years of age and older.
For treatment of delayed neutrophil recovery or graft failure after autologous or allogeneic bone marrow transplantation in adult and pediatric patients two years of age and older.
To increase survival in adult and pediatric patients from birth to 17 years of age acutely exposed to myelosuppressive doses of radiation (Hematopoietic Syndrome of Acute Radiation Syndrome [H-ARS]).
Important Safety Information for Leukine (sargramostim)
Contraindications

LEUKINE is contraindicated in patients with known hypersensitivity to human granulocyte-macrophage colony stimulating factor such as sargramostim (GM-CSF), yeast-derived products, or any component of LEUKINE.
Warnings and Precautions

Serious hypersensitivity reactions, including anaphylactic reactions, have been reported with LEUKINE. If any serious allergic or anaphylactic reaction occurs, immediately discontinue LEUKINE therapy and institute medical management. Permanently discontinue LEUKINE in patients with serious allergic reactions.
LEUKINE can cause infusion-related reactions, including respiratory distress, hypoxia, flushing, hypotension, syncope and/or tachycardia. Observe closely during infusion, particularly in patients with preexisting lung disease, as dose adjustment or discontinuation may be required.
Do not administer LEUKINE simultaneously with or within 24 hours preceding cytotoxic chemotherapy or radiotherapy or within 24 hours following chemotherapy.
Edema, capillary leak syndrome, pleural and/or pericardial effusion have been reported in patients after LEUKINE administration. LEUKINE should be used with caution and monitored in patients with preexisting fluid retention, pulmonary infiltrates, or congestive heart failure.
Supraventricular arrhythmia has been reported in uncontrolled studies during LEUKINE administration, particularly in patients with a previous history of cardiac arrhythmia. Use LEUKINE with caution in patients with preexisting cardiac disease.
If absolute neutrophil count (ANC) is greater than 20,000 cells/mm3 or if white blood cell (WBC) counts are greater than 50,000/mm3, LEUKINE administration should be interrupted or the dose reduced by half. Twice weekly monitoring of CBC with differential should be performed.
LEUKINE therapy should be discontinued if disease progression is detected during treatment.
Treatment with LEUKINE may induce neutralizing anti-drug antibodies. Use LEUKINE for the shortest duration required.
Liquid solutions containing benzyl alcohol (including LEUKINE Injection) or LEUKINE for Injection reconstituted with Bacteriostatic Water for Injection, USP (0.9 percent benzyl alcohol) should not be administered to neonates and low birth weight infants.
Concomitant use of drugs that can potentiate the myeloproliferative effects of LEUKINE should be avoided.
Adverse Reactions
Adverse events occurring in greater than 10 percent of patients receiving LEUKINE in controlled clinical trials and reported in a higher frequency than placebo are:

In Autologous bone marrow transplantation (BMT) patients–asthenia, malaise, diarrhea, rash, peripheral edema, urinary tract disorder
In Allogeneic BMT patients–abdominal pain, chills, chest pain, diarrhea, nausea, vomiting, hematemesis, dysphagia, gastro intestinal (GI) hemorrhage, pruritus, bone pain, arthralgia, eye hemorrhage, hypertension, tachycardia, bilirubinemia, hyperglycemia, increased creatinine, hypomagnesemia, edema, pharyngitis, epistaxis, dyspnea, insomnia, anxiety, high glucose, low albumin
In AML patients–fever, weight loss, nausea, vomiting, anorexia, skin reactions, metabolic laboratory abnormalities, edema
