The Food and Drug Administration on Aug. 27 approved Nourianz (istradefylline) tablets as an add-on treatment to levodopa/carbidopa in adult patients with Parkinson’s disease experiencing off episodes. During off episodes, patients’ medications do not work well, and symptoms such as tremor and difficulty walking increase.

The effectiveness of Nourianz for this indication was shown in four 12-week placebo-controlled clinical studies that included 1,143 participants. In all four studies, patients treated with Nourianz experienced a statistically significant decrease from baseline in daily off time, compared with patients who received placebo.

The most common adverse reactions to istradefylline with an incidence of 5% or greater and occurring more frequently than with placebo were dyskinesia (15%, 17%, and 8%, for Nourianz 20 mg, 40 mg, and placebo, respectively), dizziness (3%, 6%, and 4%), constipation (5%, 6%, and 3%), nausea (4%, 6%, and 5%), hallucination (2%, 6%, and 3%), and insomnia (1%, 6%, and 4%). In clinical trials, 1% of patients treated with Nourianz 20 mg or 40 mg discontinued treatment because of dyskinesia, compared with no patients who received placebo.

In addition,one patient treated with Nourianz 40 mg experienced impulse control disorder, compared with no patients who received Nourianz 20 mg or placebo.

If hallucinations, psychotic behavior, or impulsive or compulsive behavior occurs, a dosage reduction or stoppage should be considered, according to the FDA. Use of Nourianz during pregnancy is not recommended, and women of childbearing potential should be advised to use contraception during treatment.

The maximum recommended dosage in patients taking strong CYP3A4 inhibitors is 20 mg once daily, and clinicians should avoid use of Nourianz with strong CYP3A4 inducers.

Istradefylline is the first adenosine A2A receptor antagonist for use in Parkinson’s disease in the United States, and the drug provides patients with a novel nondopaminergic daily oral treatment option, according to a news release from Kyowa Kirin, the company that markets the drug.

Since 2013, istradefylline has been marketed at Nouriast in Japan, where it is indicated for the wearing-off phenomenon in patients with Parkinson’s disease who take preparations containing levodopa.

Calquence earns breakthrough designation for CLL monotherapy

Article Type
Changed
Fri, 12/16/2022 - 11:33

 

The Food and Drug Administration has granted breakthrough therapy designation to acalabrutinib (Calquence) as a monotherapy for adults with chronic lymphocytic leukemia (CLL).

The Bruton tyrosine kinase inhibitor is already approved for the treatment of adults with mantle cell lymphoma who have received at least one prior therapy, and multiple trials are underway to evaluate the drug’s use in a variety of B-cell malignancies, according to the drug’s sponsor, AstraZeneca.

The current designation was based on preliminary results from two phase 3 trials – ELEVATE-TN and ASCEND. In the three-arm ELEVATE-TN trial, researchers evaluated acalabrutinib alone or in combination with obinutuzumab versus chlorambucil plus obinutuzumab in previously untreated patients with CLL. In the two-arm ASCEND trial, previously treated patients with CLL were randomized to receive acalabrutinib monotherapy or the physician’s choice of either rituximab plus idelalisib or rituximab plus bendamustine.



Interim analyses of the two trials showed that acalabrutinib alone, or in combination, significantly improved progression-free survival without raising safety concerns.

Breakthrough therapy designation allows for an expedited review by the FDA for treatments aimed at treating serious conditions where there is preliminary clinical evidence showing a substantial improvement over an available therapy or a clinically significant endpoint.

FDA approves Taltz for treatment of ankylosing spondylitis

Article Type

Tue, 08/27/2019 - 11:44

 

The Food and Drug Administration has approved a subcutaneous injection formulation of ixekizumab (Taltz) at 80 mg/mL for the treatment of adult patients with active ankylosing spondylitis (AS), according to a press release from Eli Lilly.

Olivier Le Moal/Getty Images

AS is the third indication for ixekizumab, along with moderate to severe plaque psoriasis in adult patients who are candidates for systemic therapy or phototherapy and active psoriatic arthritis in adults.

Approval of the humanized interleukin-17A antagonist was based on results from a pair of randomized, double-blind, placebo-controlled, phase 3 studies involving 657 adult patients with active AS: the COAST-V trial in those naive to biologic disease-modifying antirheumatic drugs (bDMARDs) and the COAST-W trial in those who were intolerant or had inadequate response to tumor necrosis factor (TNF) inhibitors. The primary endpoint in both trials was achievement of 40% improvement in Assessment of Spondyloarthritis International Society criteria (ASAS40) at 16 weeks, compared with placebo.



In COAST-V, 48% of patients who received ixekizumab achieved ASAS40, compared with 18% of controls (P less than .0001). In COAST-W, 25% of patients who received ixekizumab achieved ASAS40 versus 13% of controls (P less than .05). The adverse events reported during both trials were consistent with the safety profile in patients who receive ixekizumab for the treatment of plaque psoriasis, including injection-site reactions, upper respiratory tract infections, nausea, and tinea infections.

“Results from the phase 3 clinical trial program in ankylosing spondylitis show that Taltz helped reduce pain and inflammation and improve function in patients who had never been treated with a bDMARD as well as those who previously failed TNF inhibitors. This approval is an important milestone for patients and physicians who are looking for a much-needed alternative to address symptoms of AS,” said Philip Mease, MD, of Providence St. Joseph Health and the University of Washington, both in Seattle.

First death from severe lung illness associated with vaping reported in Illinois

Article Type

Tue, 08/27/2019 - 10:12

The first death to occur in a patient with severe lung illness associated with e-cigarette product use has been reported in Illinois, officials announced at a Centers for Disease Control and Prevention telebriefing.

The cause for the mysterious lung illnesses has not been determined, but an infectious disease does not appear to be implicated. As of yesterday, 193 potential cases have been identified in 22 states since June 28.

No specific product has been implicated in all cases, and it is unclear if there is a common cause or if these are several diseases with a similar presentation.

Wisconsin and Illinois have asked the CDC to directly assist them in their investigations of cases. Other states are handling their own investigations. Further information is available from the CDC at cdc.gov/e-cigarettes.

There have been 22 cases of the illness in Illinois and an additional 12 individuals are being evaluated as possible cases, according to Jennifer Layden, MD, PhD, chief medical officer and state epidemiologist, Illinois Department of Public Health.

Illinois is working with the CDC and the Food and Drug Administration to investigate devices that affected patients have used. No specific product has been implicated across all cases; all patients have reported vaping in recent months Several patients in Illinois have reported using tetrahydrocannabinol (THC) product oils, but Dr. Layden reiterated the investigations are reliant on information reported by affected patients only.

Mitch Zeller, JD, director, Center for Tobacco Products at the FDA, said product samples from a number of states are being evaluated to determine their contents. The FDA is examining samples sent and trying to identify product contents.

The cases reported to date have been in adults aged 17-38 years and have occurred primarily men. The investigation is in a relatively early stage and is working with incomplete case reports. These will become standardized to include more specific information, such as the name of the product, where it was purchased, and whether it was used as intended or whether other products were added, he said.

As e-cigarettes are not a new product, it’s possible that cases of this illness has been occurring but that the link was not recognized, and the cases were neither captured nor reported, said Brian King, PhD, MPH, deputy director, Research Translation, Office on Smoking and Health, CDC. He noted that e-cigarettes may contain “a variety of constituents that could be problematic in terms of pulmonary illness,” such as ingredients in certain flavorings and ultrafine particulates.

The agencies are now trying to harmonize reporting across all states so cases can be evaluated in a more standardized way. Information on standardized reporting on a national level will be issued in the next few days, according to the CDC.

The CDC notified U.S. health care systems and clinicians about the illnesses and what to watch for via a Clinician Outreach and Communication Activity Clinical Action Message.

In general, patients have reported a gradual onset of symptoms including shortness of breath or chest pain that increased over days or weeks before hospital admission. Gastrointestinal symptoms including vomiting, diarrhea, and fatigue have been reported by some.

Approval of this once-daily, selective histamine 3–receptor antagonist/inverse agonist was based on a pair of multicenter, randomized, double-blind, placebo-controlled studies that included a total of 261 patients. Patients in both studies experienced statistically significant improvements in excessive daytime sleepiness according to Epworth Sleepiness Scale scores.

Rates of adverse advents at or greater than 5% and more than double that of placebo included insomnia (6%), nausea (6%), and anxiety (5%). Patients with severe liver disease should not use pitolisant. Pitolisant has not been evaluated in patients under 18 years of age, and patients who are pregnant or planning to become pregnant are encouraged to enroll in a pregnancy exposure registry.

Full prescribing information, including contraindications and warnings, can be found on the FDA website.

FDA approves lefamulin for community-acquired bacterial pneumonia treatment

Article Type

Fri, 08/23/2019 - 11:21

 

The Food and Drug Administration has announced its approval of lefamulin (Xenleta) for the treatment of community-acquired bacterial pneumonia in adults.

Olivier Le Moal/Getty Images

Approval was based on results of two clinical trials assessing a total of 1,289 people with community-acquired bacterial pneumonia. In these trials, lefamulin was compared with moxifloxacin with and without linezolid. Patients who received lefamulin had similar rates of treatment success as those taking moxifloxacin alone or moxifloxacin plus linezolid.

The most common adverse reactions associated with lefamulin include diarrhea, nausea, reactions at the injection site, elevated liver enzymes, and vomiting. Patients with prolonged QT interval, patients with arrhythmias, patients receiving treatment with antiarrhythmic agents, and patients receiving other drugs that prolong the QT interval are contraindicated. In addition, because of evidence of fetal harm in animal studies, pregnant women should be advised of potential risks before receiving lefamulin.

“This new drug provides another option for the treatment of patients with community-acquired bacterial pneumonia, a serious disease. For managing this serious disease, it is important for physicians and patients to have treatment options,” Ed Cox, MD, MPH, director of the FDA’s Office of Antimicrobial Products, said in the press release.

Patients who received lefamulin had similar rates of treatment success as those taking moxifloxacin alone or moxifloxacin plus linezolid.

The most common adverse reactions associated with lefamulin include diarrhea, nausea, reactions at the injection site, elevated liver enzymes, and vomiting. Patients with prolonged QT interval, patients with arrhythmias, patients receiving treatment with antiarrhythmic agents, and patients receiving other drugs that prolong the QT interval are contraindicated. In addition, because of evidence of fetal harm in animal studies, pregnant women should be advised of potential risks before receiving lefamulin.

“This new drug provides another option for the treatment of patients with community-acquired bacterial pneumonia, a serious disease. For managing this serious disease, it is important for physicians and patients to have treatment options,” Ed Cox, MD, MPH, director of the FDA’s Office of Antimicrobial Products, said in the press release.

New measles outbreak reported in western N.Y.

Article Type

Mon, 09/16/2019 - 10:15

 

A new measles outbreak in western New York has affected five people within a Mennonite community, according to the New York State Department of Health.

The five cases in Wyoming County, located east of Buffalo, were reported Aug. 8 and no further cases have been confirmed as of Aug. 16, the county health department said on its website.

Those five cases, along with six new cases in Rockland County, N.Y., and 10 more around the country, brought the total for the Centers for Disease Control and Prevention’s latest reporting week to 21 and the total for the year to 1,203, the CDC said Aug. 19. Measles cases have been confirmed in 30 states so far this year, according to the CDC.

Along with Wyoming County and Rockland County (296 cases since Sept. 2018), the CDC currently is tracking outbreaks in New York City (653 cases since Sept. 2018), Washington state (85 cases in 2019; 13 in the current outbreak), California (65 cases in 2019; 5 in the current outbreak), and Texas (21 cases in 2019; 6 in the current outbreak).

“More than 75% of the cases this year are linked to outbreaks in New York and New York City,” the CDC said on its website, while also noting that “124 of the people who got measles this year were hospitalized, and 64 reported having complications, including pneumonia and encephalitis.”

New transfusion guidelines for thalassemia

Article Type
Changed
Fri, 08/16/2019 - 17:20

 

Fresher blood products are not necessarily better for patients with beta thalassemia, according to a pair of experts.

Dr. Ashutosh Lal

Red blood cell units stored less than 2 weeks are ideal, but older units are acceptable, and phenotype matching should take priority over unit age, advised Ashutosh Lal, MD, and Elliott Vichinsky, MD, both of UCSF Benioff Children’s Hospital Oakland (Calif.). They discussed these and other recommendations for transfusing patients with thalassemia during a webinar hosted by the Centers for Disease Control and Prevention.

Indications for transfusion

Dr. Lal said patients with beta thalassemia major should be transfused if their hemoglobin is less than 7 g/dL on two occasions 2 weeks apart at baseline, or if their hemoglobin is greater than 7 g/dL and they have symptoms of anemia.

Patients with hemoglobin E beta thalassemia major should be transfused only if they have symptoms of anemia.



“The rationale is that, in beta thalassemia major, it is well established that, once the hemoglobin levels fall below 7 g/dL in young children, there is going to be massive bone marrow expansion, and there will be severe symptoms from anemia,” Dr. Lal said. “But the relationship of hemoglobin with symptoms in E beta thalassemia is less precise.”

The symptoms that should prompt transfusion include slowed growth, skeletal facial changes, splenomegaly, symptomatic or moderate to severe extramedullary hematopoiesis, cerebrovascular events, venous thromboembolism, pulmonary hypertension, osteoporotic fracture, and impaired quality of life in adults.

Dr. Lal said physicians should consider a 6-month trial of transfusions if the indication is unclear. He also noted that red cell antigen genotyping should be performed in all patients who may need transfusions.

Blood products

Dr. Lal said beta thalassemia patients should receive packed red blood cells that are leukoreduced prior to storage. The storage solution can be citrate-phosphate-dextrose solution with adenine (hematocrit 75%) or additive solution (hematocrit 60%).

“It’s important to note that the hematocrit of the two is quite different, and that needs to be inculcated into the decisions on how much volume to transfuse to younger children,” Dr. Lal said.

He noted that units should not be irradiated, as this damages the red cell membrane. And patients with severe allergic reactions should receive washed red blood cells because washing units removes residual donor plasma proteins.

Finally, units should be less than 2 weeks old if possible. Dr. Lal said using fresh units increases the survival of red blood cells post transfusion. However, he and Dr. Vichinsky both stressed that older units are acceptable, and phenotype matching is more important than the age of the unit.

Phenotype matching

Beta thalassemia patients who do not have preexisting alloantibodies or have transient autoantibodies should be matched to Rh and Kell, according to Dr. Lal.

Patients with preexisting alloantibodies should be matched to Rh, Kell, Duffy, Kidd, S, and the specific alloantibody. Patients with persistent autoantibodies should be matched to Rh, Kell, Duffy, Kidd, S, and any alloantibody.

Patients who start transfusions after 5 years of age should be matched to Rh, Kell, Duffy, Kidd, and S. Pregnant patients should be matched to Rh, Kell, Duffy, Kidd, and S, and units should be cytomegalovirus negative.

 

 

How to transfuse

Dr. Lal said the pretransfusion hemoglobin target is 10 g/dL, with a range of 9.5-10.5 g/dL in beta thalassemia major and a range of 9.0-10.5 g/dL for E beta thalassemia. A target of 10 g/dL is adequate for most individuals, Dr. Lal said, but he recommends individualization of hemoglobin target for patients with E beta thalassemia.

In general, patients should be transfused every 3 weeks, although 4 weeks is acceptable in younger children and those with hemoglobin E beta thalassemia.

As for the volume of a transfusion, children should receive 4 mL per kg of body weight, per gram increase in hemoglobin desired. Partial units can be used to avoid undertransfusion.

For adults, in general, those with pretransfusion hemoglobin less than 10 g/dL should receive three units, and those with pretransfusion hemoglobin of 10 g/dL or greater should receive two units.

The hemoglobin threshold should be adjusted based on fatigue or bone pain, Dr. Lal said. He also noted that patients with intact spleens have higher transfusion needs.

The rate of transfusion should be 5 mL/kg/hour in children and 200-300 mL/hour in adults, based on tolerance. Patients with impaired cardiac function should receive a reduced blood volume at a reduced rate.

Non–transfusion dependent thalassemia

Dr. Vichinsky discussed recommendations for non–transfusion dependent thalassemia (NTDT), noting that these patients may need transient transfusions to prevent morbidity.

Dr. Elliott Vichinsky

Hemoglobin should not be the sole determinant of transfusion need in NTDT patients, he said. Their well-being – activity level, growth, and skeletal changes – is more important than hemoglobin levels. However, patients with hemoglobin levels less than 7 g/dL often have severe morbidity, and those with levels of 10 g/dL or greater are usually protected from severe morbidity.

Indications for transfusion in NTDT patients include:
 

  • Growth failure.
  • Hematopoietic tumors.
  • Pulmonary hypertension.
  • Silent brain infarcts.
  • Skin ulcers.
  • Severe bone pain.
  • Poor quality of life.
  • Frequent hemolytic crises.
  • Marked and enlarging spleen.
  • Failure of secondary sex development.
  • Cosmetic and facial changes.
  • Pregnancy.

“There is a risk to transfusing this population,” Dr. Vichinsky said. “They’re older, and when you transfuse them, they can get iron overloaded.”

He added that splenectomized NTDT patients have a high risk of alloimmunization, and the transfusion duration should be serially reevaluated in NTDT patients.

Alpha thalassemia major

For alpha thalassemia major, Dr. Vichinsky discussed the importance of prevention, screening, and fetal therapy. He said couples with a fetus at risk of alpha thalassemia major should be identified early and offered, in addition to termination, the option of early fetal transfusion.

Dr. Vichinsky recommended prenatal testing and monitoring of at-risk pregnancies with ultrasound. If the fetus requires a transfusion, monitoring hemoglobin Barts and hemoglobin A is necessary.

A fetus that requires a transfusion should receive packed red blood cells that are cytomegalovirus negative, are less than 7 days old, have been irradiated, have a hemoglobin mass greater than 75%, and have been optimally cross matched with the mother first.

“These babies appear, with serial transfusions, to survive and have a relatively normal neonatal period,” Dr. Vichinsky said.

He added, however, that postnatal management of alpha thalassemia major involves an aggressive transfusion protocol. These patients should be transfused to a higher hemoglobin level than patients with beta thalassemia – roughly 12 g/dL versus 10 g/dL.

These and Dr. Lal’s recommendations are based on information in the Standards of Care Guidelines for Thalassemia – Oakland 2011, the Thalassemia International Federation Guidelines – 2014, the Thalassemia Management Checklists: United States – 2018, the Thalassemia Western Consortium Consensus: US – 2019, and the International Collaboration for Transfusion Medicine Guidelines – 2019.

Dr. Lal and Dr. Vichinsky did not disclose any conflicts of interest.

FDA approves upadacitinib for rheumatoid arthritis

Article Type
Changed
Fri, 08/16/2019 - 15:39

Upadacitinib (Rinvoq) has been approved by the Food and Drug Administration for treatment of adults with moderately to severely active RA, according to a release from its developer. The indication specifies that patients must have shown inadequate response or intolerance to methotrexate.

The approval is based on the SELECT program, which included 4,400 patients across five studies that tested the oral Janus kinase inhibitor in various settings, such as alone or with methotrexate. All primary and secondary endpoints were met in these trials. For example, among patients with inadequate response to methotrexate in one study, 68% of those treated with 15-mg upadacitinib monotherapy achieved 20% improvement in American College of Rheumatology response criteria (ACR20) at week 14 versus 41% of those who had continued on methotrexate. In another study of patients with in adequate response to methotrexate, 71% of those treated with upadacitinib/methotrexate combination therapy achieved ACR20 at week 12 versus 36% of those receiving placebo and methotrexate. Compared with other treatments, better rates of clinical remission and radiographic inhibition were seen with upadacitinib-based therapies, too.

Upadacitinib carries a boxed warning – the most serious warning the FDA issues – for risks of serious infection, malignancy, and thrombosis; these serious risks should be weighed against treatment benefits in any patients with increased risk for these problems or currently experiencing any of them. Concomitant use with other JAK inhibitors, biologic DMARDs, or with potent immunosuppressants is not recommended; its use also is not recommended for patients with severe hepatic impairment. The most common adverse reactions are upper respiratory tract infection, nausea, cough, and pyrexia. Live vaccines should be avoided with patients taking this drug, and patients who are breastfeeding should be advised against use of it.

More prescribing information can be found in the drug’s label, which can be found on the FDA’s website.

Upadacitinib is also being evaluated for treatment of other immune-mediated diseases.
