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 most common adverse reactions, in ≥20% of adults with newly diagnosed CP Ph+ CML or CP, AP, or BP Ph+ CML with resistance or intolerance to prior therapy (N=814) were diarrhea (80%), rash (44%), nausea (44%), abdominal pain (43%), vomiting (33%), fatigue (33%), hepatic dysfunction (33%), respiratory tract infection (25%), pyrexia (24%), and headache (21%).

The most common laboratory abnormalities that worsened from baseline in ≥20% of adults were creatinine increased (93%), hemoglobin decreased (90%), lymphocyte count decreased (72%), platelets decreased (69%), ALT increased (58%), calcium decreased (53%), white blood cell count decreased (52%), absolute neutrophils count decreased (50%), AST increased (50%), glucose increased (46%), phosphorus decreased (44%), urate increased (41%), alkaline phosphatase increased (40%), lipase increased (36%), creatine kinase increased (29%), and amylase increased (24%).

The most common adverse reactions, in ≥20% of pediatric patients (N=49) were diarrhea (82%), abdominal pain (73%), vomiting (55%), nausea (49%), rash (49%), fatigue (37%), hepatic dysfunction (37%), headache (35%), pyrexia (31%), decreased appetite (27%), and constipation (20%).

Adverse Reactions in Adult Patients With Newly-Diagnosed CP CML

The clinical trial randomized and treated 533 patients with newly-diagnosed CP CML to receive BOSULIF 400 mg daily or imatinib 400 mg daily as single agents (Newly-Diagnosed CP CML Study) [see Clinical Studies (14.1)]. The safety population (received at least 1 dose of BOSULIF) included:

•
two hundred sixty-eight (268) patients with newly-diagnosed CP CML had a median duration of BOSULIF treatment of 55 months (range: 0.3 to 60 months) and a median dose intensity of 394 mg/day.

Pediatric Patients with Newly-Diagnosed CP Ph+ CML or CP Ph+ CML that is Resistant or Intolerant to Prior Therapy

The safety of BOSULIF was evaluated in BCHILD, a single-arm trial for the treatment of pediatric patients aged 1 year and older with newly-diagnosed CP Ph+ CML or in patients with CP Ph+ CML who are resistant or intolerant to prior therapy [see Clinical Studies (14.3)]. Patients received BOSULIF (n = 49) 300 mg/m2 to 400 mg/m2 orally once daily until disease progression or unacceptable toxicity. The median time on treatment with BOSULIF was 12.2 months (range, 0.2 to 60.9 months). Among patients who received BOSULIF, 77.6% were exposed for 6 months or longer and 51% were exposed for one year or longer.

Permanent discontinuation of BOSULIF due to an adverse reaction occurred in 20% of patients. Adverse reactions which resulted in permanent discontinuation in 2 or more patients included ALT increased (6%), AST increased (4%), diarrhea (4%), fatigue (4%) and rash maculo-papular (4%).

The most common adverse reactions, in ≥20% of BOSULIF-treated pediatric patients were diarrhea, abdominal pain, vomiting, nausea, rash, fatigue, hepatic dysfunction, headache, pyrexia, decreased appetite, and constipation.

Pediatric Patients with Newly-Diagnosed CP Ph+ CML or CP Ph+ CML that is Resistant or Intolerant to Prior Therapy

The safety of BOSULIF was evaluated in BCHILD, a single-arm trial for the treatment of pediatric patients aged 1 year and older with newly-diagnosed CP Ph+ CML or in patients with CP Ph+ CML who are resistant or intolerant to prior therapy [see Clinical Studies (14.3)]. Patients received BOSULIF (n = 49) 300 mg/m2 to 400 mg/m2 orally once daily until disease progression or unacceptable toxicity. The median time on treatment with BOSULIF was 12.2 months (range, 0.2 to 60.9 months). Among patients who received BOSULIF, 77.6% were exposed for 6 months or longer and 51% were exposed for one year or longer.

Permanent discontinuation of BOSULIF due to an adverse reaction occurred in 20% of patients. Adverse reactions which resulted in permanent discontinuation in 2 or more patients included ALT increased (6%), AST increased (4%), diarrhea (4%), fatigue (4%) and rash maculo-papular (4%).

The most common adverse reactions, in ≥20% of BOSULIF-treated pediatric patients were diarrhea, abdominal pain, vomiting, nausea, rash, fatigue, hepatic dysfunction, headache, pyrexia, decreased appetite, and constipation.

Table 11 summarizes the adverse reactions in BCHILD.

Additional Adverse Reactions From Multiple Clinical Trials

The following adverse reactions were reported in patients in clinical trials with BOSULIF (less than 10% of BOSULIF-treated patients). They represent an evaluation of the adverse reaction data from all 1372 patients with leukemia who received at least 1 dose of single-agent BOSULIF. These adverse reactions are presented by system organ class and are ranked by frequency. These adverse reactions are included based on clinical relevance and ranked in order of decreasing seriousness within each category.

Blood and Lymphatic System Disorders: 0.1% and less than 1% - Febrile neutropenia

Cardiac Disorders: 1% and less than 10% - Pericardial effusion; 0.1% and less than 1% - Pericarditis

Ear and Labyrinth Disorders: 1% and less than 10% - Tinnitus

Endocrine Disorders: 1% and less than 10% - Hypothyroidism; 0.1% and less than 1% - Hyperthyroidism

Gastrointestinal Disorders: 1% and less than 10% - Gastritis, Pancreatitis (includes Edematous pancreatitis, Pancreatic enzymes increased, Pancreatitis, Pancreatitis acute, Pancreatitis chronic), Gastrointestinal hemorrhage (includes Anal hemorrhage, Gastric hemorrhage, Gastrointestinal hemorrhage, Intestinal hemorrhage, Lower gastrointestinal hemorrhage, Rectal hemorrhage, Upper gastrointestinal hemorrhage)

General Disorders and Administrative Site Conditions: 1% and less than 10% - Pain

Immune System Disorders: 1% and less than 10% - Drug hypersensitivity; 0.1% and less than 1% - Anaphylactic shock

Infections and Infestations: 1% and less than 10% - Bronchitis

Investigations: 1% and less than 10% - Electrocardiogram QT prolonged (includes Electrocardiogram QT prolonged, Long QT syndrome)

Metabolism and Nutrition Disorders: 1% and less than 10% - Dehydration

Musculoskeletal and Connective Tissue Disorders: 1% and less than 10% - Myalgia

Nervous System Disorders: 1% and less than 10% - Dysgeusia

Renal and Urinary Disorders: 1% and less than 10% - Acute kidney injury, Renal impairment, Renal failure

Respiratory, Thoracic and Mediastinal Disorders: 1% and less than 10% - Pulmonary hypertension (includes Pulmonary hypertension, Pulmonary arterial hypertension, Pulmonary arterial pressure increased); 0.1% and less than 1% - Acute pulmonary edema (includes Acute pulmonary edema, Pulmonary edema), Interstitial lung disease, Respiratory failure

Skin and Subcutaneous Disorders: 0.1% and less than 1% - Erythema multiforme

6.2 Postmarketing Experience

The following additional adverse reactions have been identified during post-approval use of BOSULIF. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

Blood and Lymphatic System Disorders: Thrombotic microangiopathy

Skin and Subcutaneous Tissue Disorders: Stevens-Johnson syndrome
