UP FRONT in understanding hematologic disorders, malignant and nonmalignant. I believe that what underlies every inch of progress in collaborative clinical trials and clinical research skills has been a core belief to develop hypothesis-driven stud- ies that improve patient care. Of course, now we can use molecular or genetic tools to look at prognosis for a variety of conditions. This means we can have con- versations with patients’ families that are evidence-based, and we can offer them new therapies that address the specific molecular mutations discovered in the lab. There also have been monumental changes in the ways we think about caring for individuals with complex ill- nesses. Practicing hematology allows us to have remarkably intense and meaning- ful relationships with patients, making a difference in their lives while also moving the field forward.

Laboratory abnormalities were summarized up to the end of treatment + 42 days but prior to the start of a new anti-cancer therapy. 6.2 Immunogenicity The detection of antibody formation is highly dependent on the sensitivity and specificity of the assay. Additionally, the observed incidence of antibody (including neutralizing antibody) positivity in an assay may be influenced by several factors including assay methodology, sample handling, timing of sample collection, concomitant medications, and underlying disease. For these reasons, comparison of the incidence of antibodies to inotuzumab ozogamicin in the studies described below with the incidence of antibodies in other studies or to other products may be misleading. In clinical studies of BESPONSA in patients with relapsed or refractory ALL, the immunogenicity of BESPONSA was evaluated using an electrochemiluminescence (ECL)-based immunoassay to test for anti-inotuzumab ozogamicin antibodies. For patients whose sera tested positive for anti-inotuzumab ozogamicin antibodies, a cell-based luminescence assay was performed to detect neutralizing antibodies. In clinical studies of BESPONSA in patients with relapsed or refractory ALL, 7/236 patients (3%) tested positive for anti-inotuzumab ozogamicin antibodies. No patients tested positive for neutralizing anti-inotuzumab ozogamicin antibodies. In patients who tested positive for anti-inotuzumab ozogamicin antibodies, the presence of anti- inotuzumab ozogamicin antibodies did not affect clearance following BESPONSA treatment. 7. DRUG INTERACTIONS Drugs That Prolong the QT Interval Concomitant use of BESPONSA with drugs known to prolong the QT interval or induce Torsades de Pointes may increase the risk of a clinically significant QTc interval prolongation. Discontinue or use alternative concomitant drugs that do not prolong QT/ QTc interval while the patient is using BESPONSA. When it is not feasible to avoid concomitant use of drugs known to prolong QT/QTc, obtain ECGs and electrolytes prior to the start of treatment, after initiation of any drug known to prolong QTc, and periodically monitor as clinically indicated during treatment. 8. USE IN SPECIFIC POPULATIONS 8.1 Pregnancy Risk Summary Based on its mechanism of action and findings from animal studies, BESPONSA can cause embryo-fetal harm when administered to a pregnant woman. There are no available data on BESPONSA use in pregnant women to inform a drug-associated risk of major birth defects and miscarriage. In rat embryo-fetal development studies, inotuzumab ozogamicin caused embryo-fetal toxicity at maternal systemic exposures that were ≥ 0.4 times the exposure in patients at the maximum recommended dose, based on AUC. If this drug is used during pregnancy, or if the patient becomes pregnant while taking this drug, advise the patient of the potential risk to a fetus. What is the best part of your day, and what is the worst? Every day, I look forward to walking in to the office and engaging with my team, which includes physicians, nurses, clinical researchers, and professionals. They all come to work each day just as committed to serving our patients and conducting research that can make a difference in our patients’ lives. The worst part of my day is billing, which I think many readers Adverse outcomes in pregnancy occur regardless of the health of the mother or the use of medications. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies are 2-4% and 15-20%, respectively. Data Animal Data In embryo-fetal development studies in rats, pregnant animals received daily intravenous doses of inotuzumab ozogamicin up to 0.36 mg/m 2 during the period of organogenesis. Embryo-fetal toxicities including increased resorptions and fetal growth retardation as evidenced by decreased live fetal weights and delayed skeletal ossification were observed at ≥ 0.11 mg/m 2 (approximately 2 times the exposure in patients at the maximum recommended dose, based on AUC). Fetal growth retardation also occurred at 0.04 mg/m 2 (approximately 0.4 times the exposure in patients at the maximum recommended dose, based on AUC). In an embryo-fetal development study in rabbits, pregnant animals received daily intravenous doses up to 0.15 mg/m 2 (approximately 3 times the exposure in patients at the maximum recommended dose, based on AUC) during the period of organogenesis. At a dose of 0.15 mg/m 2 , slight maternal toxicity was observed in the absence of any effects on embryo-fetal development. 8.2 Lactation Risk Summary There are no data on the presence of inotuzumab ozogamicin or its metabolites in human milk, the effects on the breastfed infant, or the effects on milk production. Because of the potential for adverse reactions in breastfed infants, advise women not to breastfeed during treatment with BESPONSA and for at least 2 months after the last dose. 8.3 Females and Males of Reproductive Potential Pregnancy Testing Based on its mechanism of action and findings from animal studies, BESPONSA can cause embryo-fetal harm when administered to a pregnant woman. Verify the pregnancy status of females of reproductive potential prior to initiating BESPONSA. Contraception Females Advise females of reproductive potential to avoid becoming pregnant while receiving BESPONSA. Advise females of reproductive potential to use effective contraception during treatment with BESPONSA and for at least 8 months after the last dose. Males Advise males with female partners of reproductive potential to use effective contraception during treatment with BESPONSA and for at least 5 months after the last dose. Infertility Females Based on findings in animals, BESPONSA may impair fertility in females of reproductive potential. Males Based on findings in animals, BESPONSA may impair fertility in males of reproductive potential. 8.4 Pediatric Use Safety and effectiveness have not been established in pediatric patients. 8.5 Geriatric Use In the INO-VATE ALL trial, 30/164 patients (18%) treated with BESPONSA were ≥65 years of age. No differences in responses were identified between older and younger patients. Based on a population pharmacokinetic analysis in 765 patients, no adjustment to the starting dose is required based on age. 8.6 Hepatic Impairment Based on a population pharmacokinetic analysis, the clearance of inotuzumab ozogamicin in patients with mild hepatic impairment (total bilirubin ≤ ULN and AST > ULN, or total bilirubin > 1.0-1.5 x ULN and AST any level; n=150) was similar to patients with normal hepatic function (total bilirubin/AST ≤ ULN; n=611). In patients with moderate (total bilirubin > 1.5-3 x ULN and AST any level; n=3) and severe hepatic impairment (total bilirubin > 3 x ULN and AST any level; n=1), inotuzumab ozogamicin clearance did not appear to be reduced. No adjustment to the starting dose is required when administering BESPONSA to patients with total bilirubin ≤ 1.5 x ULN and AST/ALT ≤ 2.5 x ULN. There is limited safety information available in patients with total bilirubin > 1.5 x ULN and/or AST/ALT > 2.5 x ULN prior to dosing. Interrupt dosing until recovery of total bilirubin to ≤ 1.5 x ULN and AST/ALT ≤ to 2.5 x ULN prior to each dose unless due to Gilbert’s syndrome or hemolysis. Permanently discontinue treatment if total bilirubin does not recover to ≤ 1.5 x ULN or AST/ALT does not recover to ≤ 2.5 x ULN. 17. PATIENT COUNSELING INFORMATION Hepatotoxicity, Including Hepatic VOD (also known as SOS) Inform patients that liver problems, including severe, life-threatening, or fatal VOD, and increases in liver tests may develop during BESPONSA treatment. Inform patients that they should seek immediate medical advice if they experience symptoms of VOD, which may include elevated bilirubin, rapid weight gain, and abdominal swelling that may be painful. Inform patients that they should carefully consider the benefit/risk of BESPONSA treatment if they have a prior history of VOD or serious ongoing liver disease. Increased Risk of Post-HSCT Non-Relapse Mortality Inform patients that there is an increased risk of post-HSCT non-relapse mortality after receiving BESPONSA, that the most common causes of post-HSCT non-relapse mortality included infection and VOD. Advise patients to report signs and symptoms of infection. Myelosuppression Inform patients that decreased blood counts, which may be life-threatening, may develop during BESPONSA treatment and that complications associated with decreased blood counts may include infections, which may be life- threatening or fatal, and bleeding/hemorrhage events. Inform patients that signs and symptoms of infection, bleeding/hemorrhage, or other effects of decreased blood counts should be reported during treatment with BESPONSA. Infusion Related Reactions Advise patients to contact their health care provider if they experience symptoms such as fever, chills, rash, or breathing problems during the infusion of BESPONSA. QT Interval Prolongation Inform patients of symptoms that may be indicative of significant QTc prolongation including dizziness, lightheadedness, and syncope. Advise patients to report these symptoms and the use of all medications to their healthcare provider. Embryo-Fetal Toxicity Advise males and females of reproductive potential to use effective contraception during BESPONSA treatment and for at least 5 and 8 months after the last dose, respectively. Advise females of reproductive potential to avoid becoming pregnant while receiving BESPONSA. Advise women to contact their healthcare provider if they become pregnant, or if pregnancy is suspected, during treatment with BESPONSA. Inform the patient of the potential risk to the fetus. Lactation Advise women against breastfeeding while receiving BESPONSA and for 2 months after the last dose. Dr. Thompson and 2017 ASH President Kenneth Anderson, MD. can identify with. It’s a tedious but necessary task. Enough said. What do you enjoy doing outside of work? I spend as much time as I can with my husband Garry. We enjoy traveling and visiting family and friends. Our favorite place to travel is Barcelona and the area of southern Spain – we love the architecture and love, love, love the food. We’re finishing renovations to our brick American Foursquare house that was built in 1918, and sometimes it’s great just to spend weekends at home with Garry and our chocolate Labrador Retriever, Coltrane, just working in the garden or going to the beach. This year, we’re growing a variety of vegetables and flowers. Digging in the dirt isn’t something everyone wants to do, but it’s therapeutic for me.
