The US Food and Drug Administration (FDA) has granted accelerated approval for venetoclax (Venclexta) to treat patients with chronic lymphocytic leukemia (CLL) who have 17p deletion and have received at least one prior therapy.

Venetoclax will be available in the US within about a week, according to the companies developing the drug, AbbVie and Genentech (a member of the

Roche Group).

The companies said they plan to offer patient assistance programs for qualifying patients who wish to receive venetoclax.

Venetoclax (formerly ABT-199) is the first FDA-approved treatment that targets the BCL-2 protein, which is overexpressed in many patients with CLL.

The drug is indicated for daily use after 17p deletion is confirmed via the FDA-approved companion diagnostic Vysis CLL FISH probe kit, which is manufactured by Abbott Molecular.

The FDA granted venetoclax accelerated approval rather than traditional approval because the drug has not yet shown a clinical benefit. The FDA’s accelerated approval program allows conditional approval of a drug that fills an unmet medical need for a serious condition.

Accelerated approval is based on a surrogate or intermediate endpoint—in this case, overall response rate—that is reasonably likely to predict clinical benefit. Continued approval of venetoclax for the aforementioned indication may be contingent upon verification of clinical benefit in confirmatory trials.

The FDA previously granted venetoclax breakthrough therapy designation, priority review status, and orphan drug designation.

Phase 2 trial

Results from the pivotal phase 2 trial of venetoclax (M13-982, NCT01889186) were presented at the 2015 ASH Annual Meeting. According to those data, the trial enrolled 107 patients with relapsed or refractory CLL and 17p deletion.

Patients received venetoclax at 400 mg once daily following a weekly ramp-up schedule for the first 5 weeks. The primary endpoint was overall response rate, as determined by an independent review committee.

Eighty-five patients responded to treatment, for an overall response rate of 79.4%. Eight patients (7.5%) achieved a complete response or complete response with incomplete count recovery, 3 (2.8%) had a near partial response, and 74 (69.2%) had a partial response. Twenty-two patients (20.6%) did not respond.

As of the ASH presentation, the median duration of response had not been reached. The same was true for progression-free survival and overall survival. The progression-free survival estimate for 12 months was 72.0%, and the overall survival estimate was 86.7%.

Treatment-emergent adverse events of any grade occurred in 96% of patients. The most frequent were neutropenia (43%), diarrhea (29%), nausea (29%), anemia (27%), fatigue (22%), pyrexia (20%), thrombocytopenia (19%), hyperphosphatemia (16%), vomiting (15%), and upper respiratory tract infection (15%). (About 22% of patients had neutropenia at baseline.)

The most frequent grade 3/4 adverse events were neutropenia (40%), anemia (18%), and thrombocytopenia (15%). Infections occurred in 72% of patients, with 20% of patients experiencing grade 3 or higher infections.

Serious adverse events occurred in 55% of patients, the most common being pyrexia (7%), autoimmune hemolytic anemia (7%), pneumonia (6%), and febrile neutropenia (5%).

Laboratory tumor lysis syndrome (TLS) occurred in 5 patients during the ramp-up period only. Two patients required a dose interruption of 1 day each. There were no clinical TLS events.

In the past, TLS has caused deaths in patients receiving venetoclax. In response, AbbVie stopped dose-escalation in patients receiving the drug and suspended enrollment in phase 1 trials.

However, researchers subsequently found that a modified dosing schedule, prophylaxis, and patient monitoring can reduce the risk of TLS.

Venetoclax is currently being evaluated in phase 3 trials for the treatment of relapsed, refractory, and previously untreated CLL.

The European Commission (EC) has approved eltrombopag (Revolade), a once-daily oral thrombopoietin receptor agonist, to treat pediatric patients (age 1 and older) with chronic immune thrombocytopenia (ITP) that is refractory to other therapies.

This approval includes the use of tablets and a new oral suspension formulation of eltrombopag, which is designed for younger children who may not be able to swallow tablets.

The approval applies to all 28 member states of the European Union plus Iceland, Norway, and Liechtenstein.

Eltrombopag was previously approved by the EC for use in adults with refractory chronic ITP. The drug is also approved in the EC to treat adults with severe aplastic anemia and adults with chronic hepatitis C virus infection who have thrombocytopenia.

Eltrombopag is made by Novartis. For more details on the drug, see the full Summary of Product Characteristics, available on the European Medicines Agency’s website.

The EC’s latest approval of eltrombopag was based on data from 2 double-blind, placebo-controlled trials—the phase 2 PETIT trial and the phase 3 PETIT2 trial.

PETIT trials: Efficacy

The PETIT trial included 67 ITP patients stratified by age cohort (12-17 years, 6-11 years, and 1-5 years). They were randomized (2:1) to receive eltrombopag or placebo for 7 weeks. The eltrombopag dose was titrated to a target platelet count of 50-200 x 10⁹/L.

The primary efficacy endpoint was the proportion of subjects achieving platelet counts of 50 x 10⁹/L or higher at least once between days 8 and 43 of the randomized period of the study.

Significantly more patients in the eltrombopag arm met this endpoint—62.2%—compared to 31.8% in the placebo arm (P=0.011).

The PETIT2 trial enrolled 92 patients with chronic ITP who were randomized (2:1) to receive eltrombopag or placebo for 13 weeks. The eltrombopag dose was titrated to a target platelet count of 50-200 x 10⁹/L.

The primary efficacy endpoint was the proportion of subjects who achieved platelet counts of 50 x 10⁹/L or higher for at least 6 out of 8 weeks, between weeks 5 and 12 of the randomized period.

Significantly more patients in the eltrombopag arm met this endpoint—41.3%—compared to 3.4% of patients in the placebo arm (P<0.001).

PETIT trials: Safety

For both trials, there were 107 eltrombopag-treated patients evaluable for safety.

The most common adverse events that occurred more frequently in the eltrombopag arms than the placebo arms were upper respiratory tract infection, nasopharyngitis, cough, diarrhea, pyrexia, rhinitis, abdominal pain, oropharyngeal pain, toothache, increased ALT/AST, rash, and rhinorrhea.

Serious adverse events were reported in 8% of patients during the randomized part of both trials, although no serious adverse event occurred in more than 1 patient.

An ALT elevation of at least 3 times the upper limit of normal occurred in 5% of eltrombopag-treated patients. Of those patients, 2% had ALT increases of at least 5 times the upper limit of normal.

There were no deaths or thromboembolic events during either study.

Micrograph showing AML

The European Medicines Agency (EMA) has recommended orphan designation for the WT1 cancer vaccine galinpepimut-S as a treatment for patients

with acute myeloid leukemia (AML) and patients with malignant pleural mesothelioma (MPM).

The EMA’s opinion has been forwarded to the European Commission (EC), which makes the final decision.

The EC grants orphan designation to products intended to treat, prevent, or diagnose a life-threatening condition affecting up to 5 in 10,000 people in the European Union. The product must provide significant benefit to those affected by the condition.

Orphan designation from the EC provides companies with certain development incentives, including protocol assistance, a type of scientific advice specific for orphan drugs, and 10 years of market exclusivity once the drug is approved for use.

About the vaccine

The WT1 vaccine consists of 4 modified peptide chains that induce an innate immune response (CD4+/CD8+ T cells) against the WT1 antigen. The vaccine is administered in combination with an adjuvant and an immune modulator to improve the immune response to the target.

Based on the vaccine’s mechanism and the accumulating evidence of activity in mid-stage trials, researchers believe the WT1 vaccine may have the potential to complement currently available therapies by destroying residual tumor cells of cancers in remission and providing ongoing immune surveillance for recurrent tumors.

The WT1 vaccine could potentially target more than 20 cancers that overexpress WT1, many of which are associated with relapse rates of up to 80% or more, as seen in patients with AML and MPM.

The vaccine is being developed by SELLAS Life Sciences Group. The company said that, in a phase 1 study, AML patients treated with the vaccine had a median overall survival of more than 3 years.

In a phase 2 trial of the vaccine, adult AML patients had a median overall survival of around 4 years. Data from the phase 2 trial are scheduled to be presented at the 2016 ASCO Annual Meeting.

SELLAS said it expects to begin a phase 3 trial of the vaccine in AML patients later this year.

Daratumumab (Darzalex)

The European Medicines Agency’s Committee for Medicinal Products for Human Use (CHMP) has recommended conditional marketing authorization for daratumumab (Darzalex), a first-in-class monoclonal antibody targeting CD38.

The recommended indication for daratumumab is as monotherapy for adults with relapsed and refractory multiple myeloma (MM).

The patients must have progressed on their last therapy and have received treatment with both a proteasome inhibitor and an immunomodulatory agent.

The CHMP’s positive opinion will now be reviewed by the European Commission, which has the authority to grant marketing authorization for medicines in the European Economic Area.

The European Commission’s final decision on daratumumab is anticipated in the coming months.

About conditional authorization

A product may receive conditional marketing authorization if the CHMP finds that, although comprehensive clinical data on the safety and efficacy of the product are not available, all of the following requirements are met:

• The risk-benefit balance of the product is positive
• The company developing the product will likely be in a position to provide comprehensive clinical data in the future
• Unmet medical needs will be fulfilled
• The benefit to public health of the immediate availability of the product outweighs the risk inherent in the fact that additional data are still required.

Conditional marketing authorizations are valid for 1 year, on a renewable basis. The holder will be required to complete ongoing studies or to conduct new studies with a view to confirming that the benefit-risk balance of a product is positive. In addition, specific obligations may be imposed in relation to the collection of pharmacovigilance data.

About daratumumab

Daratumumab is the first CD38-directed monoclonal antibody recommended for approval in Europe. It works by binding to CD38, a signaling molecule highly expressed on the surface of MM cells regardless of stage of disease.

In binding to CD38, daratumumab triggers the patient’s own immune system to attack the cancer cells, resulting in rapid tumor cell death through multiple, immune-mediated mechanisms of action and through immunomodulatory effects, in addition to direct tumor cell death via apoptosis.

The CHMP’s positive opinion of daratumumab was based on a review of data from the phase 2 SIRIUS study, the phase 1/2 GEN501 study, and 3 additional supportive studies.

The GEN501 study enrolled 102 patients with relapsed MM or relapsed MM that was refractory to 2 or more prior lines of therapy. The patients received daratumumab at a range of doses and on a number of different schedules.

The results suggested daratumumab is most effective at a dose of 16 mg/kg. At this dose, the overall response rate was 36%. Most adverse events in this study were grade 1 or 2, although serious events did occur.

The SIRIUS study enrolled 124 MM patients who had received 3 or more prior lines of therapy. They received daratumumab at different doses and on different schedules, but 106 patients received the drug at 16 mg/kg.

Twenty-nine percent of the 106 patients responded to treatment, and the median duration of response was 7 months. Thirty percent of patients experienced serious adverse events.

Findings from a combined efficacy analysis of the GEN501 and SIRIUS trials demonstrated that, after a mean follow-up of 14.8 months, the estimated median overall survival for patients who received single-agent daratumumab at 16 mg/kg was 20 months.

Five phase 3 clinical studies with daratumumab in MM patients—in relapsed and frontline settings—are ongoing. Additional studies are ongoing or planned to assess the drug’s potential in other malignant and pre-malignant diseases in which CD38 is expressed.

Janssen has exclusive worldwide rights to the development, manufacturing, and commercialization of daratumumab for all potential indications. Janssen licensed daratumumab from Genmab A/S in August 2012.

The results suggested daratumumab is most effective at a dose of 16 mg/kg. At this dose, the overall response rate was 36%. Most adverse events in this study were grade 1 or 2, although serious events did occur.

The SIRIUS study enrolled 124 MM patients who had received 3 or more prior lines of therapy. They received daratumumab at different doses and on different schedules, but 106 patients received the drug at 16 mg/kg.

Twenty-nine percent of the 106 patients responded to treatment, and the median duration of response was 7 months. Thirty percent of patients experienced serious adverse events.

Findings from a combined efficacy analysis of the GEN501 and SIRIUS trials demonstrated that, after a mean follow-up of 14.8 months, the estimated median overall survival for patients who received single-agent daratumumab at 16 mg/kg was 20 months.

Five phase 3 clinical studies with daratumumab in MM patients—in relapsed and frontline settings—are ongoing. Additional studies are ongoing or planned to assess the drug’s potential in other malignant and pre-malignant diseases in which CD38 is expressed.

The European Medicines Agency’s Committee for Medicinal Products for Human Use (CHMP) has recommended conditional marketing authorization for daratumumab (Darzalex), a first-in-class monoclonal antibody targeting CD38.

The recommended indication for daratumumab is as monotherapy for adults with relapsed and refractory multiple myeloma (MM).

The patients must have progressed on their last therapy and have received treatment with both a proteasome inhibitor and an immunomodulatory agent.

The CHMP’s positive opinion will now be reviewed by the European Commission, which has the authority to grant marketing authorization for medicines in the European Economic Area.

The European Commission’s final decision on daratumumab is anticipated in the coming months.

About conditional authorization

A product may receive conditional marketing authorization if the CHMP finds that, although comprehensive clinical data on the safety and efficacy of the product are not available, all of the following requirements are met:

• The risk-benefit balance of the product is positive
• The company developing the product will likely be in a position to provide comprehensive clinical data in the future
• Unmet medical needs will be fulfilled
• The benefit to public health of the immediate availability of the product outweighs the risk inherent in the fact that additional data are still required.

Conditional marketing authorizations are valid for 1 year, on a renewable basis. The holder will be required to complete ongoing studies or to conduct new studies with a view to confirming that the benefit-risk balance of a product is positive. In addition, specific obligations may be imposed in relation to the collection of pharmacovigilance data.

About daratumumab

Daratumumab is the first CD38-directed monoclonal antibody recommended for approval in Europe. It works by binding to CD38, a signaling molecule highly expressed on the surface of MM cells regardless of stage of disease.

In binding to CD38, daratumumab triggers the patient’s own immune system to attack the cancer cells, resulting in rapid tumor cell death through multiple, immune-mediated mechanisms of action and through immunomodulatory effects, in addition to direct tumor cell death via apoptosis.

The CHMP’s positive opinion of daratumumab was based on a review of data from the phase 2 SIRIUS study, the phase 1/2 GEN501 study, and 3 additional supportive studies.

The GEN501 study enrolled 102 patients with relapsed MM or relapsed MM that was refractory to 2 or more prior lines of therapy. The patients received daratumumab at a range of doses and on a number of different schedules.

Acute myeloid leukemia

The US Food and Drug Administration (FDA) has granted orphan designation for the radioimmunoconjugate Iomab-B to be used as a conditioning agent for patients with relapsed or refractory acute myeloid leukemia (AML) who are undergoing hematopoietic stem cell transplant (HSCT).

Iomab-B is a radioimmunoconjugate consisting of BC8, a novel murine monoclonal antibody, and the radioisotope iodine-131.

BC8 targets CD45, a pan-leukocytic antigen widely expressed on white blood cells. This makes BC8 potentially useful in targeting white blood cells in preparation for HSCT.

When labeled with radioactive isotopes, BC8 carries radioactivity directly to the site of cancerous growth and bone marrow, while avoiding the effects of radiation on most healthy tissues, according to Actinium Pharmaceuticals, Inc., the company developing Iomab-B.

Actinium said Iomab-B has been tested as a myeloconditioning/myeloablative agent in more than 250 patients with incurable hematologic malignancies.

The company has released data from a phase 1/2 trial of Iomab-B in patients with relapsed/refractory AML who are older than 50.

The data show that patients who received Iomab-B before HSCT (n=27) had higher rates of survival at 1 and 2 years than patients who underwent HSCT with conventional myeloablative conditioning (n=10) or chemotherapy (n=61).

One-year survival rates were 30% in the Iomab-B arm and 10% each in the conventional conditioning and chemotherapy arms. Two-year survival rates were 19%, 0%, and 0%, respectively.

Now, Actinium is planning a phase 3 trial of Iomab-B in relapsed/refractory AML patients over the age of 55.

About orphan designation

The FDA grants orphan designation to drugs intended to treat diseases or conditions affecting fewer than 200,000 patients in the US.

The designation provides the drug’s sponsor with various development incentives, including opportunities to apply for research-related tax credits and grant funding, assistance in designing clinical trials, and 7 years of US market exclusivity if the drug is approved.

The US Food and Drug Administration (FDA) has approved the use of defibrotide sodium (Defitelio).

The product can now be used to treat adult and pediatric patients who develop hepatic veno-occlusive disease (VOD), also known as sinusoidal obstruction syndrome, with renal or pulmonary dysfunction after receiving a hematopoietic stem cell transplant (HSCT).

Defibrotide sodium is the first FDA-approved therapy for patients with this rare, potentially fatal complication.

Defibrotide sodium is a product of Jazz Pharmaceuticals, Inc. The company said shipments of the drug to distribution channels will begin within a week.

The recommended dose and schedule for defibrotide sodium is 6.25 mg/kg every 6 hours, given as a 2-hour intravenous infusion, for at least 21 days, and continued until VOD resolution or up to 60 days of treatment.

In vitro defibrotide sodium has profibrinolytic activity. The use of defibrotide sodium is contraindicated in patients receiving concurrent anticoagulants or fibrinolytic therapies. Hemorrhage and hypersensitivity reactions are the major potential adverse reactions.

The FDA previously granted the defibrotide sodium application priority review status, and the drug received orphan drug designation from the FDA for the treatment of hepatic VOD.

Full prescribing information for defibrotide sodium can be found on the FDA website.

Trial results

The FDA’s approval of defibrotide sodium is supported by data in 528 patients treated on 3 studies: a phase 2 trial, a phase 3 trial, and an expanded access study. Data from the expanded access study were presented at the 2015 BMT Tandem Meetings, and data from the phase 3 trial were published in Blood earlier this year.

The 528 patients all had hepatic VOD with multi-organ dysfunction after HSCT. They received defibrotide sodium at 6.25 mg/kg intravenously every 6 hours until resolution of VOD.

The approval was based on survival at day +100 after HSCT. The day +100 survival rates for Study 1 (phase 3, n=102), Study 2 (phase 2, n=75), and Study 3 (expanded access, n=351) were 38%, 44%, and 45%, respectively.

Based on published reports and analyses of patient-level data, the day +100 survival rates were 21% to 31% for patients with hepatic VOD with renal or pulmonary dysfunction who received supportive care or interventions other than defibrotide sodium.

The safety of defibrotide sodium to support approval is based on data from 176 patients in the clinical development program for the treatment of VOD with renal and/or pulmonary dysfunction following HSCT.

The most common adverse events (incidence ≥10% and independent of causality) were hypotension, diarrhea, vomiting, nausea, and epistaxis. The most common serious adverse events (incidence ≥5% and independent of causality) were hypotension (11%) and pulmonary alveolar hemorrhage (7%).

Prescription medications

A new study suggests that cost-sharing policies in the US create a barrier to the treatment of chronic myeloid leukemia (CML).

Researchers examined Medicare claims data and found that “Part D” (prescription drug plan) co-insurance policies for “specialty drugs” seem to be reducing or delaying the use of tyrosine kinase inhibitors (TKIs) in patients with CML.

The team reported these findings in the American Journal of Managed Care.

“High out-of-pocket costs for specialty drugs appear to pose a very real barrier to treatment,” said study author Jalpa A. Doshi, PhD, of the Perelman School of Medicine at the University of Pennsylvania in Philadelphia.

While there is no standard definition for specialty drugs, the term typically refers to medications requiring special handling, administration, or monitoring. Most are aimed at treating chronic or life-threatening diseases.

Although specialty drugs typically tend to offer significant medical advances over non-specialty drugs, they are correspondingly more expensive. In 2014, such drugs accounted for less than 1% of prescriptions in the US but nearly a third of total prescription spending.

While insurers have been imposing higher cost-sharing requirements as part of their efforts to manage specialty drug spending, there has been limited information about the corresponding impact on patients.

“[I]t was particularly important to examine the extent to which the aggressive cost-sharing policies for specialty drugs seen under Medicare Part D, which are increasingly making their way into the private insurance market, adversely impact access to these treatments even for a condition like cancer,” Dr Doshi said.

So she and her colleagues examined the impact of specialty drug cost-sharing under the Medicare Part D prescription drug benefit on patients with CML. The team analyzed Medicare data on patients who were newly diagnosed with CML to examine whether and how quickly they initiated TKI treatment.

The researchers compared patients who were eligible for low-income subsidies and therefore faced nominal out-of-pocket costs to patients who faced average out-of-pocket costs of $2600 or more for their first 30-day TKI prescription fill.

Results showed that patients in the high-cost group were significantly less likely than the low-cost group to have a Part D claim for a TKI prescription within 6 months of their CML diagnosis. The rates were 45.3% and 66.9%, respectively (P<0.001).

Patients in the high cost-sharing group also took twice as long, on average, to initiate TKI treatment. The mean time to fill a TKI prescription was 50.9 days in the high-cost group and 23.7 days in the low-cost group (P<0.001).

“Medicare Part D was created to increase access to prescription drug treatment among beneficiaries, but our data suggest that current policies are interfering with that goal when it comes to specialty drugs,” Dr Doshi said.

She added that making Part D out-of-pocket costs more consistent and limiting them to more reasonable sums would help mitigate this negative impact.

Dr Doshi and her colleagues are now pursuing further studies of the impact of Part D cost-sharing policies in different disease areas. They hope to gain a better understanding of changes in drug access and of the long-range clinical outcomes and costs associated with any delays or interruptions in treatment.

“We need to know if the current aggressive cost-sharing arrangements have adverse long-term impacts on health and perhaps, paradoxically, increase overall spending due to complications of poorly controlled disease,” Dr Doshi said.

The European Commission (EC) has granted orphan designation to BMN 270, an investigational gene therapy, for the treatment of patients with hemophilia A.

BMN 270 is an adeno-associated virus-factor VIII (FVIII) vector designed to restore FVIII plasma concentrations in these patients.

The EC grants orphan designation to products intended to treat, prevent, or diagnose a life-threatening condition affecting up to 5 in 10,000 people in the European Union.

The product must provide significant benefit to those affected by the condition.

Orphan designation from the EC provides companies with certain development incentives, including protocol assistance, a type of scientific advice specific for orphan drugs, and 10 years of market exclusivity once the drug is approved for use.

BMN 270 is under development by BioMarin Pharmaceutical Inc.

BioMarin is conducting a phase 1/2 study to evaluate the safety and efficacy of BMN 270 in up to 12 patients with severe hemophilia A.

Researchers are assessing the safety of a single infusion of BMN 270 and the change in FVIII expression level from baseline to 16 weeks after infusion.

The group is also assessing the impact of BMN 270 on the frequency of FVIII replacement therapy, the number of bleeding episodes requiring treatment, and any potential immune responses.

Patients will be monitored for safety and durability of effect for 5 years. BioMarin plans to provide an update on this trial in April.

BMN 270 also has orphan designation in the US.

The group is also assessing the impact of BMN 270 on the frequency of FVIII replacement therapy, the number of bleeding episodes requiring treatment, and any potential immune responses.

Patients will be monitored for safety and durability of effect for 5 years. BioMarin plans to provide an update on this trial in April.

BMN 270 also has orphan designation in the US.

The US Food and Drug Administration (FDA) has granted breakthrough therapy designation to NI-0501 for the treatment of patients with primary hemophagocytic lymphohistiocytosis (HLH) who have refractory disease or recurrent/progressive disease during conventional therapy.

NI-0501 is a fully human monoclonal antibody (mAb) targeting interferon-gamma (IFNγ) that is being developed by Novimmune.

The biological activity of IFNγ, which is considered to have a pivotal pathogenic role in HLH, is neutralized by NI-0501.

“The FDA’s designation of NI-0501 as a breakthrough therapy recognizes the potential of NI-0501 to address an important unmet medical need in a disease with still high mortality, and for which there are no approved treatments,” said Novimmune Chairman and Chief Executive Officer Eduard Holdener.

The breakthrough therapy designation is intended to expedite the development and review of new therapies for serious or life threatening conditions, which have shown encouraging early clinical results demonstrating substantial improvement on a clinically significant endpoint over available therapies.

The FDA granted breakthrough designation to NI-0501 on the basis of data from a phase 2 study in children with primary HLH. Preliminary results from this study were presented at the 2015 ASH Annual Meeting.

The trial included 16 patients—8 males and 8 females. Their median age was 1.2 years (range, 0.2-13).

Two patients were receiving NI-0501 as first-line treatment, and the rest were receiving the mAb as second-line treatment. Patients had previously received dexamethasone (n=13), methylprednisone (n=2), etoposide (n=13), ATG (n=4), cyclosporine A (n=6), and “other” therapy (n=4).

NI-0501 was given at a starting dose of 1 mg/kg every 3 days, with possible dose increases guided by pharmacokinetic data and/or clinical response in each patient. The mAb was administered with dexamethasone at a dose of 5 mg/m² to 10 mg/m², but dexamethasone could be tapered during the treatment course.

The treatment duration ranged from 4 weeks to 8 weeks, and the follow-up period was 4 weeks.

Efficacy

One patient was excluded from the analysis due to a lymphoma diagnosis after enrollment. Two patients were still receiving treatment as of the ASH presentation, and 13 have completed treatment.

Among the patients who completed therapy, 4 had an insufficient response. Two of these patients died, and 2 proceeded to allogeneic hematopoietic stem cell transplant (HSCT) after receiving additional agents to control their disease.

Nine patients achieved a favorable response to NI-0501. Seven of these patients proceeded to HSCT, and 2 were awaiting HSCT at the time of the ASH presentation, with their disease well-controlled.

Post-transplant follow-up is still early for most patients, but 2 patients have follow-up greater than 1 year. One child died of graft-vs-host disease around day 45, but the remaining patients who went on to HSCT were still alive as of the ASH presentation.

Safety

No off-target effects of NI-0501 were observed, and none of the patients withdrew from the study for safety reasons.

There were 14 serious adverse events reported in 8 patients, but only 1 of these events was considered treatment-related.

The patient had necrotizing fasciitis following P aeruginosa skin infection, which resolved. This event was considered treatment-related by an investigator but not by the data monitoring committee or the sponsor.

Three patients had died as of the ASH presentation, but none of the deaths were related to NI-0501. Two patients died of HLH/multi-organ failure, and 1 died of graft-vs-host disease.

In light of recently reported safety concerns, the European Medicines Agency’s (EMA) Pharmacovigilance Risk Assessment Committee (PRAC) has issued provisional advice for doctors and patients using idelalisib (Zydelig).

The EMA recently began reviewing the safety of idelalisib because of serious adverse events, most of which were infection-related, that were reported in 3 clinical trials investigating idelalisib in combination with other drugs.

These trials have since been stopped.

Now, the PRAC is making provisional recommendations to ensure idelalisib is used as safely as possible outside of clinical trials.

These recommendations will be forwarded to the European Commission, which will issue a provisional legally binding decision applicable in all European Union (EU) member states.

In the EU, idelalisib is approved as monotherapy for adults with follicular lymphoma that is refractory to 2 prior lines of treatment.

Idelalisib is also approved for use in combination with rituximab to treat adults with chronic lymphocytic leukemia (CLL) who have received at least 1 prior therapy or as first-line treatment in the presence of 17p deletion or TP53 mutation in CLL patients considered unsuitable for chemo-immunotherapy.

Recommendations

The PRAC is recommending that previously untreated CLL patients with 17p deletion or TP53 mutation do not begin treatment with idelalisib. In addition, doctors should re-evaluate each patient taking idelalisib as first-line treatment for CLL and only continue treatment if the benefits outweigh the risks.

Idelalisib can continue to be used in combination, only with rituximab, in CLL patients who have received at least 1 prior therapy and as monotherapy in patients with follicular lymphoma that is refractory to 2 lines of treatment.

Patients with any evidence of ongoing systemic infection should not be started on treatment with idelalisib.

And patients should be informed about the risk of serious infections with idelalisib.

All patients who do receive idelalisib should take antibiotics to prevent Pneumocystis jirovecii pneumonia, and they should be monitored for respiratory signs and symptoms. Regular clinical and laboratory monitoring for cytomegalovirus infection is also recommended.

Patients should have regular blood tests to detect neutropenia. In case a patient has moderate or severe neutropenia, treatment with idelalisib may have to be interrupted, in line with the updated summary of product characteristics.

The EMA said further details on these provisional measures will be provided in writing to healthcare professionals, and the product information will be updated accordingly.

Likewise, further information on the review of idelalisib will be provided as necessary and once the review is finished.

About the review

The EMA’s review of idelalisib started after a higher rate of serious adverse events, including deaths, was seen in 3 clinical trials evaluating the addition of idelalisib to standard therapy in first-line CLL and relapsed indolent non-Hodgkin lymphoma (NHL).

Most of the deaths were related to infections such as Pneumocystis jirovecii pneumonia and cytomegalovirus infection. Other excess deaths were related mainly to respiratory events.

The NHL studies (NCT01732926 and NCT01732913) included patients with disease characteristics different from those covered by the currently approved indication for idelalisib and investigated combinations of drugs that are not currently approved in the EU—idelalisib plus rituximab for NHL and idelalisib plus bendamustine and rituximab for NHL.

The CLL trial (NCT01980888) involved patients who had not received previous treatment, some of whom had the 17p deletion or TP53 mutation. However, the trial also investigated a combination of drugs not currently approved in the EU—idelalisib plus bendamustine and rituximab.

At present, the PRAC is conducting the review. Once the PRAC is finished, its recommendations will be forwarded to the EMA’s Committee for Medicinal Products for Human Use, which will adopt a final opinion.

The European Commission will take this opinion into account and adopt a legally binding decision that is applicable in all EU member states.
