ALL

A first-in-class oral inhibitor of valosin-containing protein (VCP) p97 showed significant activity against human B acute lymphoblastic leukemia (B-ALL) cells, including those with the most common fusion genes seen in pediatric and adult B-ALL, researchers reported.

The drug, dubbed CB-5083 (Cleave Biosciences), induces cell death by causing endoplasmic reticulum stress, to which B-ALL cells are “distinctly vulnerable,” wrote Gabriele Gugliotta, MD, PhD, of Cedars-Sinai Medical Center in Los Angeles, Calif., and her coinvestigators. In their study, CB-5083 significantly reduced the viability of 10 B-ALL cell lines tested, and did so at blood concentrations that caused no significant toxicities in mice. Human B-ALL cells also showed no signs of upfront drug resistance, the researchers wrote in Neoplasia.

CB-5083 received an FDA orphan drug designation in 2015 for treating multiple myeloma, and also has shown activity against solid tumors. In the study, exposing BALL1 and OP1 B-ALL cell lines to CB-5083 triggered “early and strong” apoptosis, along with a “robust” cleavage of PARP, the researchers reported (Neoplasia. 2017 Aug 24. doi: 10.1016/j.neo.2017.08.001). http://www.neoplasia.com/article/S1476-5586(17)30258-0/fulltext

The drug also reduced the viability of human B-ALL cells without genes for GRP78, GRP94, or XBP1, suggesting that CB-5083 does not require the presence of these proteins to work, the investigators said. Deficiency of X-box binding protein 1 (XBP1) predicted greater sensitivity to CB-5083, which might mean that XBP1 splicing counteracts drug activity by mitigating endoplasmic reticulum stress, they added. “Finally, vincristine was synergistic with CB-5083 in both BALL1 and OP1 [cell lines],” they wrote. “In summary, the targeting of p97 with CB-5083 is a novel promising therapeutic approach that should be further evaluated in B-ALL.”

The investigators acknowledged support from the Melamed family, Reuben Yeroushalmi, National Research Foundation Singapore, Singapore Ministry of Education, Leukemia Lymphoma Society of America, and University of Bologna, Italy. They did not report having conflicts of interest.

Adult survivors of childhood cancer have a greater cumulative burden of chronic health conditions than the general public, according to research published in The Lancet.

The study showed that, by age 50, childhood cancer survivors (CCSs) had experienced, on average, 17.1 chronic health conditions, and matched control subjects had experienced 9.2.

“The cumulative burden of chronic disease revealed in this analysis, along with the complexity and severity of chronic conditions some survivors experience, found childhood cancer survivors to be a vulnerable, medically complex population,” said study author Nickhill Bhakta, MD, of St. Jude Children’s Research Hospital in Memphis, Tennessee.

For this study, Dr Bhakta and his colleagues assessed the lifelong impact of 168 chronic health conditions—such as hepatic, thyroid, ocular, and reproductive disorders—on CCSs and control subjects.

The 3010 evaluable CCSs had survived 10 years or longer from their initial cancer diagnosis and were 18 years or older as of June 30, 2015. The 272 controls had no history of pediatric cancer and were matched to CCSs by age and sex.

At age 50, the cumulative incidence of chronic health conditions (of any grade) was 99.9% in CCSs and 96.0% in controls (P<0.0001). The cumulative incidence of grade 3 to 5 chronic health conditions was 96.0% and 84.9%, respectively (P<0.0001).

The cumulative burden for CCSs was 17.1 chronic health conditions, including 4.7 that were grade 3 to 5. For controls, the cumulative burden was 9.2 chronic health conditions, including 2.3 that were grade 3 to 5 (P<0.0001 for both comparisons).

The researchers said second neoplasms, spinal disorders, and pulmonary disease were major contributors to the excess total cumulative burden observed in CCSs. However, there was “notable heterogeneity” in burden according to the patients’ primary cancer diagnosis.

For instance, growth hormone deficiency was in the top 10th percentile of chronic health conditions for survivors of acute lymphoblastic leukemia but not for controls.

And pulmonary function deficits were in the top 10th percentile for survivors of acute myeloid leukemia and Hodgkin lymphoma but not for controls or survivors of acute lymphoblastic leukemia or non-Hodgkin lymphoma.

“This study found that the average childhood cancer survivor has a cumulative burden of chronic disease that requires a significant time investment by healthcare providers to disentangle and manage—time that community providers are unlikely to have,” Dr Bhakta said.

“The results suggest that childhood cancer survivors may benefit from the integrated, specialized healthcare delivery that is being tried for individuals infected with HIV or those with other complex, chronic health problems.”

The US Food and Drug Administration (FDA) has approved the first chimeric antigen receptor (CAR) T-cell therapy, tisagenlecleucel (Kymriah^TM, formerly CTL019).

The therapy is approved for use in children and young adults up to 25 years of age who have B-cell precursor acute lymphoblastic leukemia (ALL) that is refractory or in second or later relapse.

Tisagenlecleucel consists of autologous T cells expressing a CD19-specific CAR.

The therapy was first developed by the University of Pennsylvania. In 2012, the university and Novartis entered into a global collaboration to further research, develop, and commercialize CAR T-cell therapies. Novartis holds the worldwide rights to tisagenlecleucel and other therapies developed through the collaboration.

The application for tisagenlecleucel was supported by results from 3 clinical trials:

• A pilot study presented at the 2015 ASH Annual Meeting
• The phase 2 ENSIGN trial, which was presented at the 2016 ASH Annual Meeting
• The phase 2 ELIANA study, which was recently presented at the 22nd Congress of the European Hematology Association (EHA).

Safety concerns

The prescribing information for tisagenlecleucel includes a boxed warning noting that the treatment poses a risk of cytokine release syndrome (CRS) and neurological toxicity, both of which can be life-threatening.

Because of the risk of CRS, the FDA has expanded the approved use of tocilizumab (Actemra) to include treatment of CAR T-cell-induced severe or life-threatening CRS in patients age 2 and older.

The risk of CRS and neurological toxicity also prompted the FDA to approve tisagenlecleucel with a risk evaluation and mitigation strategy (REMS), which includes elements to assure safe use.

The FDA is requiring that hospitals and their associated clinics that dispense tisagenlecleucel be specially certified. As part of that certification, staff involved in the prescribing, dispensing, or administration of tisagenlecleucel are required to be trained to recognize and manage CRS and neurological events.

Additionally, the certified healthcare settings are required to have protocols in place to ensure that tisagenlecleucel is only given to patients after verifying that tocilizumab is available for immediate administration.

The REMS program specifies that patients be informed of the signs and symptoms of CRS and neurological toxicities following infusion and of the importance of promptly returning to the treatment site if they develop fever or other adverse reactions after receiving tisagenlecleucel.

To further evaluate the long-term safety of tisagenlecleucel, Novartis is required to conduct a post-marketing observational study involving patients who received the treatment.

Access and cost

Tisagenlecleucel will be manufactured for each individual patient at Novartis’s facility in Morris Plains, New Jersey.

Novartis said it has designed a manufacturing and supply chain platform that allows for an individualized treatment approach on a global scale. This process includes cryopreservation of a patient’s harvested cells, providing the flexibility to initiate treatment with tisagenlecleucel based on the individual patient’s condition.

Tisagenlecleucel will reportedly cost $475,000 for a single course of treatment. However, Novartis said it will help patients navigate insurance coverage and provide financial assistance for those who are uninsured or underinsured.

In addition, patients will only be required to pay for tisagenlecleucel if they respond within a month of receiving the treatment. This is a result of a collaboration between Novartis and the US Centers for Medicare and Medicaid Services that is focused on delivering value-based care. The approach is intended to include indication-based pricing for medicines and supports payments for a medicine based on the clinical outcomes achieved.

The US Food and Drug Administration (FDA) has approved tocilizumab (Actemra®) for the treatment of patients age 2 and older who have severe or life-threatening cytokine release syndrome (CRS) induced by chimeric antigen receptor (CAR) T-cell therapy.

Tocilizumab is a humanized interleukin-6 receptor antagonist.

The drug is also FDA-approved to treat adults with rheumatoid arthritis or giant cell arteritis and patients age 2 and older with polyarticular juvenile idiopathic arthritis or systemic juvenile idiopathic arthritis.

The full prescribing information for tocilizumab, which includes a boxed warning about the risk of serious infections, is available at http://www.actemra.com. The drug is jointly developed by Genentech (a member of the Roche Group) and Chugai Pharmaceutical Co.

The FDA’s latest approval of tocilizumab coincided with the FDA’s approval of the CAR T-cell therapy tisagenlecleucel (Kymriah, formerly CTL019) to treat pediatric and young adult patients with relapsed or refractory B-cell precursor acute lymphoblastic leukemia.

According to Genentech, the FDA’s decision to expand the approval of tocilizumab is based on a retrospective analysis of pooled outcome data from clinical trials of CAR T-cell therapies in patients with hematologic malignancies.

For this analysis, researchers assessed 45 pediatric and adult patients treated with tocilizumab, with or without additional high-dose corticosteroids, for severe or life-threatening CRS.

Thirty-one patients (69%) achieved a response, defined as resolution of CRS within 14 days of the first dose of tocilizumab.

No more than 2 doses of tocilizumab were needed, and no drugs other than tocilizumab and corticosteroids were used for treatment.

No adverse reactions related to tocilizumab were reported.

Indeed, FDA commissioner Scott Gottlieb, MD, said the approval marks the entry to a “new frontier in medical innovation.”

“New technologies such as gene and cell therapies hold out the potential to transform medicine and create an inflection point in our ability to treat and even cure many intractable illnesses,” he said in the press statement.

Tisagenlecleucel is a genetically modified autologous T-cell immunotherapy involving customized treatment created using a patient’s own T cells. The T cells are genetically modified to include a chimeric antigen receptor that directs the T cells to target and kill leukemia cells with CD19 surface antigen, and are then infused back into the patient. 

In a phase 2 clinical trial, the overall remission rate with tisagenlecleucel therapy was 83% in 63 children and young adults with relapsed/refractory B-cell precursor ALL for whom at least two prior lines of therapy had failed; the therapy was granted Fast Track, Priority Review, and Breakthrough Therapy designations.

“Kymriah is a first-of-its-kind treatment approach that fills an important unmet need for children and young adults with this serious disease,” Peter Marks, MD, director of the FDA’s Center for Biologics Evaluation and Research said in the press statement.

“Not only does Kymriah provide these patients with a new treatment option where very limited options existed, but a treatment option that shows promising remission and survival rates in clinical trials.”

At its meeting in July, the FDA ODAC agreed nearly unanimously that the risk mitigation plan put forward by Novartis, including planned 15-year follow-up and other mitigation measures, would be adequate for detecting serious consequences of CAR T-cell therapy.

Tisagenlecleucel will carry a boxed warning regarding the CRS risk. Additionally, due to the CRS risk and risk of neurological events, the approval requires a risk evaluation and mitigation strategy (REMS), which includes elements to assure safe use, according to an FDA press release.

Special certification will be required for hospitals and associated clinics that dispense tisagenlecleucel. As part of certification, staff will be trained in the prescribing, dispensing, or administering of the therapy, and to recognize and manage CRS and neurological events.

Novartis, the maker of tisagenlecleucel, will be required to conduct postmarketing observational study.

Indeed, FDA commissioner Scott Gottlieb, MD, said the approval marks the entry to a “new frontier in medical innovation.”

“New technologies such as gene and cell therapies hold out the potential to transform medicine and create an inflection point in our ability to treat and even cure many intractable illnesses,” he said in the press statement.

Tisagenlecleucel is a genetically modified autologous T-cell immunotherapy involving customized treatment created using a patient’s own T cells. The T cells are genetically modified to include a chimeric antigen receptor that directs the T cells to target and kill leukemia cells with CD19 surface antigen, and are then infused back into the patient. 

In a phase 2 clinical trial, the overall remission rate with tisagenlecleucel therapy was 83% in 63 children and young adults with relapsed/refractory B-cell precursor ALL for whom at least two prior lines of therapy had failed; the therapy was granted Fast Track, Priority Review, and Breakthrough Therapy designations.

“Kymriah is a first-of-its-kind treatment approach that fills an important unmet need for children and young adults with this serious disease,” Peter Marks, MD, director of the FDA’s Center for Biologics Evaluation and Research said in the press statement.

“Not only does Kymriah provide these patients with a new treatment option where very limited options existed, but a treatment option that shows promising remission and survival rates in clinical trials.”

At its meeting in July, the FDA ODAC agreed nearly unanimously that the risk mitigation plan put forward by Novartis, including planned 15-year follow-up and other mitigation measures, would be adequate for detecting serious consequences of CAR T-cell therapy.

When doctors talk about a new leukemia drug from Novartis, they ooze enthusiasm, using words like “breakthrough,” “revolutionary” and “a watershed moment.”

But when they think about how much the therapy is likely to cost, their tone turns alarmist.

“It’s going to cost a fortune,” said Ivan Borrello, MD, at Johns Hopkins Sidney Kimmel Comprehensive Cancer Center in Baltimore.

“From what we’re hearing, this will be a quantum leap more expensive than other cancer drugs,” said Leonard Saltz, MD, chief of gastrointestinal oncology at Memorial Sloan Kettering Cancer Center in New York.

Switzerland-based Novartis hasn’t announced a price for the medicine, but British health authorities have said a price of $649,000 for a one-time treatment would be justified given the significant benefits.

The cancer therapy was unanimously approved by a Food and Drug Administration advisory committee in July, and its approval seems all but certain.

The treatment, CTL019, belongs to a new class of medications called CAR T-cell therapies, which involve harvesting patients’ immune cells and genetically altering them to kill cancer. It’s been tested in patients whose leukemia has relapsed in spite of the best chemotherapy or a bone-marrow transplant.

The prognosis for these patients is normally bleak. But in a clinical trial, 83% of those treated with CAR T-cell therapy – described as a “living drug” because it derives from a patient’s own cells – have gone into remission.

CAR T cells have been successful only in a limited number of cancers, however, and are being suggested for use as a last resort when all else has failed. As a result, only a few hundred patients a year would be eligible for them, at least initially, said J. Leonard Lichtenfeld, MD, deputy chief medical officer for the American Cancer Society.

The FDA is scheduled to decide on approval by Oct. 3. The agency also is considering a CAR T-cell therapy from Kite Pharma.

A third company, Juno Therapeutics, halted the development of one its CAR T-cell therapies after five patients died from complications of the treatment.

Rather than wait for Novartis to announce a price, an advocacy group called Patients for Affordable Drugs has launched a preemptive strike, asking to meet with company officials to discuss a “fair” price for the therapy. The Novartis drug has the potential to be one of the most expensive drugs ever sold, said David Mitchell, the patients group’s president, who has been treated for multiple myeloma, a blood cancer, since 2010. (The Laura and John Arnold Foundation, which provides some funding for Kaiser Health News, supports Patients for Affordable Drugs.)

“Many people with cancer look forward with great hope to the potential of your new drug,” Mr. Mitchell wrote in a letter to Novartis. “But drugs don’t work if patients can’t afford them.”

Cancer drugs today routinely cost more than $100,000 a year. A combination therapy for melanoma sells for $250,000. Such prices are particularly outrageous, given that taxpayers fund many drugs’ early research, Mr. Mitchell said.

The federal government spent more than $200 million over 2 decades to support the basic research into CAR T-cell therapy, long before Novartis bought the rights.

The patients group urged Novartis to charge no more for the drug in the U.S. than in other developed countries.

Novartis has agreed to meet with the patients group. In a statement, Novartis said the company is “carefully considering the appropriate price for CTL019, taking into consideration the value that this treatment represents for patients, society and the healthcare system, both near-term and long-term.”

Novartis made a significant investment in CAR T-cell therapy, according to the statement.

“We employ hundreds of people around the world who work on CAR Ts, we are conducting ongoing U.S. and global clinical trials and have developed a sophisticated, FDA-validated manufacturing site and process for this personalized therapy.”

Soaring prices for cancer drugs have led many patients to cut back on treatment or skip pills, a recent Kaiser Health News analysis showed.

The effect of CAR T-cell therapies on overall health costs would initially be relatively small, because it would be used by relatively few people, Dr. Lichtenfeld said.

Health systems and insurers may struggle to pay for the treatment, however, if the FDA approves it for wider use, Dr. Lichtenfeld said. Researchers are studying CAR T cells in a number of cancers. So far, the technology seems more effective in blood cancers, such as leukemias and lymphomas.

Hidden costs could further add to patients’ financial burdens, Dr. Borrello said.

Beyond the cost of the procedure, patients would need to pay for traditional chemotherapy, which is given before CAR T-cell therapy to improve its odds of success. They would also have to foot the bill for travel and lodging to one of the 30-35 hospitals in the country equipped to provide the high-tech treatment, said Prakash Satwani, MD, a pediatric hematologist at New York-Presbyterian/Columbia University Medical Center, which plans to offer the therapy.

Because patients can develop life-threatening side effects weeks after the procedure, doctors will ask patients to stay within 2 hours of the hospital for up to a month. In New York, even budget hotels cost more than $200 a night – an expense not typically covered by insurance. Patients who develop a dangerous complication, in which the immune system overreacts and attacks vital organs, might need coverage for emergency room care, as well as lengthy stays in the ICU, Dr. Satwani said.

Doctors don’t yet know what the full range of long-term side effects will be. CAR T-cell therapies can damage healthy immune cells, including the cells that produce the antibodies that fight disease. Some patients will need long-term treatments with a product called intravenous immunoglobulin, which provides the antibodies that patients need to prevent infection, Dr. Lichtenfeld said.

Dr. Saltz, an oncologist who has long spoken out about high drug prices, said he applauded the patients group’s efforts. But he said he doubts their efforts will persuade Novartis to set a reasonably affordable price.

“I’m not optimistic that this will have much effect on the company,” said Dr. Saltz. “There’s no market pressure for the company to respond to.”

High drug prices don’t just hurt patients, Dr. Saltz said. They also drive up insurance premiums for everyone.

“They affect each and every one of us,” he said, “because these costs will be paid by anyone who has any kind of insurance coverage.”

A 3-drug combination has demonstrated long-term efficacy against acute lymphoblastic leukemia (ALL) in mice, according to research published in Nature Communications.

Researchers found that when the production of nucleotides is stopped, a DNA replication stress response is activated, and this allows ALL cells to survive.

The team used these findings to devise a 3-drug regimen that blocks both of the nucleotide biosynthetic pathways and inhibits the replication stress response.

One of the drugs is triapine (3-AP), which inhibits ribonucleotide reductase (RNR) and enhances salvage nucleotide biosynthesis.

Another drug is DI-82, which inhibits the nucleoside salvage kinase deoxycytidine kinase (dCK).

And the third drug is VE-822, which inhibits the replication stress-sensing kinase ataxia telangiectasia and Rad3-related protein (ATR).

The researchers tested these 3 drugs in a mouse model of pre-B-ALL. Starting on day 7 after inoculation of pre-B-ALL, the mice received 3-AP and DI-82 twice a day and VE-822 once a day.

The team said mice in the control group succumbed to their disease within 17 days. However, all of the mice that received the 3-drug combination were still disease-free 442 days after they had stopped treatment (on day 42).

The researchers said the combination was well-tolerated, as mice maintained their body weight and enjoyed long-term survival without any detectable pathology.

The team also tested a dosing regimen in which all 3 drugs were given once a day.

Although this was less effective than the first regimen, 4 of 5 mice had no detectable disease 313 days after stopping treatment.

Two of the researchers involved in this study are co-founders and equity holders of Trethera Corp, a company developing a dCK inhibitor known as TRE-515.

The University of California (where most of the study authors work) has patented intellectual property for small-molecule dCK inhibitors, and it was licensed by Trethera.

Inotuzumab ozogamicin therapy significantly increased the risk of sinusoidal obstruction syndrome (veno-occlusive disease) among adults with relapsed or refractory B-cell precursor acute lymphoblastic leukemia (ALL), especially when they also received follow-up hematopoietic stem cell transplantation, according to a safety analysis from the INO-VATE trial.

After a median of 9 weeks of treatment, 13% of 164 patients who received inotuzumab ozogamicin (Besponsa, Wyeth/Pfizer) developed sinusoidal obstruction syndrome, compared with less than 1% of 143 patients who received standard care, reported Hagop M. Kantarjian, MD, of the University of Texas MD Anderson Cancer Center in Houston, and his associates (Lancet Haematol. 2017 Jul 4. doi: 10.1016/ S2352-3026[17]30103-5).

Follow-up treatment with HSCT increased the risk of sinusoidal obstruction syndrome in both the intervention (22%) and standard-care (3%) groups. Among patients who did not undergo HSCT, rates of this adverse event were 3% and 0%, respectively. Five patients died from sinusoidal obstruction syndrome, all of whom received both inotuzumab ozogamicin and HSCT. The findings earned the newly approved regimen a boxed warning for severe hepatotoxicity.

The open-label, phase 3, multicenter INO-VATE study included 326 adults with CD22-positive, Philadelphia chromosome–negative or Philadelphia chromosome–positive relapsed or refractory B-cell precursor ALL. The safety analysis included 305 patients. Rates of treatment-emergent hepatotoxicities, of all grades, were 51% with inotuzumab ozogamicin and 34% with standard care. Most adverse hepatic events were grade 1-2 liver-related laboratory abnormalities, but 8% of inotuzumab ozogamicin recipients developed grade 3 or higher sinusoidal obstruction syndrome, versus less than 1% of the control group.

“After follow-up HSCT, the frequency of sinusoidal obstruction syndrome was 50% or higher in the following subgroups: patients aged 65 years or older, patients with last available pre-HSCT serum bilirubin concentration more than or equal to the upper limit of normal, and patients who received conditioning regimens with two alkylating agents,” Dr. Kantarjian and his fellow investigators wrote. Conditioning regimens that included thiotepa markedly increased the risk of sinusoidal obstruction syndrome. Additional risk factors included HSCT before study enrollment, history of liver disease, and a final pre-HSCT platelet count of less than 100 × 109 platelets per L.

Rates of sinusoidal obstruction syndrome were 42% with four to six cycles of inotuzumab ozogamicin, 23% with three cycles, 19% with two cycles, and 8% with one cycle, said the investigators. In multivariate analysis, conditioning with two alkylating agents (P = .02 compared with one alkylating agent) and pre-HSCT bilirubin of at least the upper limit of normal (P = .01) significantly increased the risk of sinusoidal obstruction syndrome during or after treatment with inotuzumab ozogamicin.

Notably, inotuzumab ozogamicin did not significantly increase the chances of survival compared with standard care among patients who also received follow-up HSCT (hazard ratio, 1.3; 97.5% confidence interval, 0.66 to 2.3; P = 0.77). Among HSCT recipients, the chances of surviving to 24 months were 39% (95% CI, 28%-50%) with inotuzumab ozogamicin and 29% (11%-49%) with standard care. Nonetheless, HSCT “offers possibility of cure in the relapsed or recurrent [ALL] setting,” the researchers wrote. Clinicians should be especially wary of sinusoidal obstruction syndrome if patients are 65 years or older, received HSCT before inotuzumab ozogamicin treatment, or have a baseline history of liver disease, they said. Strategies to minimize risk include shortening the duration of inotuzumab ozogamicin treatment and avoiding conditioning regimens that contain two alkylating agents.

Inotuzumab ozogamicin therapy significantly increased the risk of sinusoidal obstruction syndrome (veno-occlusive disease) among adults with relapsed or refractory B-cell precursor acute lymphoblastic leukemia (ALL), especially when they also received follow-up hematopoietic stem cell transplantation, according to a safety analysis from the INO-VATE trial.

After a median of 9 weeks of treatment, 13% of 164 patients who received inotuzumab ozogamicin (Besponsa, Wyeth/Pfizer) developed sinusoidal obstruction syndrome, compared with less than 1% of 143 patients who received standard care, reported Hagop M. Kantarjian, MD, of the University of Texas MD Anderson Cancer Center in Houston, and his associates (Lancet Haematol. 2017 Jul 4. doi: 10.1016/ S2352-3026[17]30103-5).

Follow-up treatment with HSCT increased the risk of sinusoidal obstruction syndrome in both the intervention (22%) and standard-care (3%) groups. Among patients who did not undergo HSCT, rates of this adverse event were 3% and 0%, respectively. Five patients died from sinusoidal obstruction syndrome, all of whom received both inotuzumab ozogamicin and HSCT. The findings earned the newly approved regimen a boxed warning for severe hepatotoxicity.

The open-label, phase 3, multicenter INO-VATE study included 326 adults with CD22-positive, Philadelphia chromosome–negative or Philadelphia chromosome–positive relapsed or refractory B-cell precursor ALL. The safety analysis included 305 patients. Rates of treatment-emergent hepatotoxicities, of all grades, were 51% with inotuzumab ozogamicin and 34% with standard care. Most adverse hepatic events were grade 1-2 liver-related laboratory abnormalities, but 8% of inotuzumab ozogamicin recipients developed grade 3 or higher sinusoidal obstruction syndrome, versus less than 1% of the control group.

“After follow-up HSCT, the frequency of sinusoidal obstruction syndrome was 50% or higher in the following subgroups: patients aged 65 years or older, patients with last available pre-HSCT serum bilirubin concentration more than or equal to the upper limit of normal, and patients who received conditioning regimens with two alkylating agents,” Dr. Kantarjian and his fellow investigators wrote. Conditioning regimens that included thiotepa markedly increased the risk of sinusoidal obstruction syndrome. Additional risk factors included HSCT before study enrollment, history of liver disease, and a final pre-HSCT platelet count of less than 100 × 109 platelets per L.

Rates of sinusoidal obstruction syndrome were 42% with four to six cycles of inotuzumab ozogamicin, 23% with three cycles, 19% with two cycles, and 8% with one cycle, said the investigators. In multivariate analysis, conditioning with two alkylating agents (P = .02 compared with one alkylating agent) and pre-HSCT bilirubin of at least the upper limit of normal (P = .01) significantly increased the risk of sinusoidal obstruction syndrome during or after treatment with inotuzumab ozogamicin.

Notably, inotuzumab ozogamicin did not significantly increase the chances of survival compared with standard care among patients who also received follow-up HSCT (hazard ratio, 1.3; 97.5% confidence interval, 0.66 to 2.3; P = 0.77). Among HSCT recipients, the chances of surviving to 24 months were 39% (95% CI, 28%-50%) with inotuzumab ozogamicin and 29% (11%-49%) with standard care. Nonetheless, HSCT “offers possibility of cure in the relapsed or recurrent [ALL] setting,” the researchers wrote. Clinicians should be especially wary of sinusoidal obstruction syndrome if patients are 65 years or older, received HSCT before inotuzumab ozogamicin treatment, or have a baseline history of liver disease, they said.

The US Food and Drug Administration (FDA) has approved inotuzumab ozogamicin (Besponsa®) for the treatment of adults with relapsed or refractory B-cell precursor acute lymphoblastic leukemia (ALL).

The labeling for inotuzumab ozogamicin includes a boxed warning stating that the drug poses a risk of hepatotoxicity, including hepatic veno-occlusive disease (or sinusoidal obstruction syndrome), as well as an increased risk of post-transplant non-relapse mortality.

The full prescribing information for inotuzumab ozogamicin is available at https://www.accessdata.fda.gov/drugsatfda_docs/label/2017/761040s000lbl.pdf.

Inotuzumab ozogamicin is an antibody-drug conjugate that consists of a monoclonal antibody targeting CD22 and a cytotoxic agent known as calicheamicin.

The product originates from a collaboration between Pfizer and Celltech (now UCB), but Pfizer has sole responsibility for all manufacturing and clinical development activities.

Inotuzumab ozogamicin was reviewed and approved under the FDA’s breakthrough therapy designation and priority review programs.

The application for inotuzumab ozogamicin was supported by results from the phase 3 INO-VATE trial, which were published in NEJM in June 2016.

The trial enrolled 326 adults with relapsed or refractory B-cell ALL. Patients received inotuzumab ozogamicin or 1 of 3 chemotherapy regimens (high-dose cytarabine, cytarabine plus mitoxantrone, or fludarabine, cytarabine, and granulocyte colony-stimulating factor).

The rate of complete remission, including incomplete hematologic recovery, was 80.7% in the inotuzumab arm and 29.4% in the chemotherapy arm (P<0.001). The median duration of remission was 4.6 months and 3.1 months, respectively (P=0.03).

Forty-one percent of patients treated with inotuzumab and 11% of those who received chemotherapy proceeded to stem cell transplant directly after treatment (P<0.001).

The median progression-free survival was 5.0 months in the inotuzumab arm and 1.8 months in the chemotherapy arm (P<0.001).

The median overall survival was 7.7 months and 6.7 months, respectively (P=0.04). This did not meet the prespecified boundary of significance (P=0.0208).

Liver-related adverse events were more common in the inotuzumab arm than the chemotherapy arm. The most frequent of these were increased aspartate aminotransferase level (20% vs 10%), hyperbilirubinemia (15% vs 10%), and increased alanine aminotransferase level (14% vs 11%).

Veno-occlusive liver disease occurred in 11% of patients in the inotuzumab arm and 1% in the chemotherapy arm.

There were 17 deaths during treatment in the inotuzumab arm and 11 in the chemotherapy arm. Four deaths were considered related to inotuzumab, and 2 were thought to be related to chemotherapy.
