The Food and Drug Administration has granted accelerated approval to acalabrutinib, a Bruton tyrosine kinase inhibitor, for the treatment of adults with mantle cell lymphoma (MCL) who have received at least one prior therapy.

Approval was based on an 81% overall response rate in a phase 2, single-arm trial (ACE-LY-004) of 124 patients with MCL who had received at least one prior treatment (40% complete response, 41% partial response), the FDA said in a statement.

The US Food and Drug Administration (FDA) has approved an intravenous (IV) formulation of rolapitant (VARUBI®) for the same indication as the oral formulation.

This means IV rolapitant is now FDA-approved for use in combination with other antiemetic agents to prevent delayed nausea and vomiting associated with initial and repeat courses of emetogenic chemotherapy in adults with cancer.

TESARO Inc., makers of rolapitant, said the US commercial launch of IV rolapitant is planned for November.

Rolapitant is a selective and competitive antagonist of human substance P/neurokinin 1 receptors, which play an important role in the delayed phase of chemotherapy-induced nausea and vomiting (CINV).

IV rolapitant features a ready-to-use, single-dose vial for administration. It does not require refrigerated storage or mixing.

The recommended dose of IV rolapitant is 166.5 mg, administered over 30 minutes. The drug is to be administered up to 2 hours before chemotherapy administration in combination with a 5-HT3 receptor antagonist and dexamethasone.

The full prescribing information for IV rolapitant is available at www.varubirx.com.

Bioequivalence trial

Results from a bioequivalence trial suggest the IV and oral formulations of rolapitant are comparable.

The study was conducted in healthy volunteers. Subjects were randomized to receive a single dose of IV rolapitant at 166.5 mg administered over 30 minutes (n=61) or oral rolapitant at 180 mg (n=62).

The primary endpoint was bioequivalence, and the 166.5 mg IV infusion of rolapitant met bioequivalence criteria.

Researchers said the safety profile of IV rolapitant was largely consistent with that of oral rolapitant, although infusion-site reactions were observed with the IV formulation. These included the sensation of warmth, abdominal pain, dizziness, and paresthesia.

These results were recently published in The Journal of Clinical Pharmacology.

Oral rolapitant trials

Two phase 3 trials showed that oral rolapitant, in combination with a 5-HT3 receptor antagonist and dexamethasone, was well tolerated and more effective than active control in preventing CINV after highly emetogenic chemotherapy.

Results from these trials (NCT01499849 and NCT01500213) were published in a single article in The Lancet Oncology.

A third phase 3 trial showed that oral rolapitant, in combination with a 5-HT3 receptor antagonist and dexamethasone, was well tolerated and more effective than active control in preventing CINV after moderately emetogenic chemotherapy.

Results from this trial (NCT01500226) were also published in The Lancet Oncology.

Survey results suggest childhood cancer survivors (CCSs) in the US are more likely than individuals without a history of cancer to experience “job lock,” or staying at a job to keep work-related health insurance.

CCSs are also more likely than individuals without a history of cancer to report problems paying medical bills and being denied health insurance.

Anne Kirchhoff, PhD, of Huntsman Cancer Institute at the University of Utah in Salt Lake City, and her colleagues reported these findings in JAMA Oncology.

The researchers analyzed 394 CCSs from pediatric oncology institutions across the US, along with 128 of their siblings who had no history of cancer. All study participants worked 35 hours or more per week.

The most common cancer diagnosis among CCSs was leukemia (35.4%), followed by Hodgkin lymphoma (14.9%). Most patients had undergone chemotherapy (77.2%), radiotherapy (63.9%), and surgery (81.1%).

Overall, sociodemographic and clinical characteristics were similar between CCSs and siblings. However, CCSs were more likely than siblings to have severe, disabling, or life-threatening chronic conditions—33.9% and 17.7%, respectively (P<0.001).

Most CCSs (88.0%) and siblings (88.5%) had employer-sponsored health insurance. Three percent of siblings and 5.3% of CCSs had individual insurance; 1.9% and 2.3%, respectively, had public insurance; and 6.7% and 4.4%, respectively, were uninsured.

Results

CCSs were more likely than siblings to report:

• Job lock—23.2% and 16.9%, respectively (P=0.16)
• Problems paying medical bills—20.1% and 12.9%, respectively (P=0.09)
• Denial of health insurance—13.4% and 1.8%, respectively (P<0.001).

In a multivariable analysis, insurance denial remained significantly more common among CCSs than siblings (relative risk [RR]=7.38).

In another multivariable analysis, 38% of CCSs with a previous insurance denial reported job lock, compared with 20% of those who never experienced insurance denial (RR=1.60). And 44% of CCSs who reported problems paying their medical bills also reported job lock, compared to 16% of those who had no problems paying medical bills (RR=2.43).

The researchers also found that female CCSs (RR=1.70) and CCSs with severe, disabling, or life-threatening chronic conditions (RR=1.72) were more likely to report job lock.

“This information gives us a feel for high-risk groups of survivors who may need more information about insurance,” Dr Kirchhoff said. “Many people experience a gap in education and literacy around insurance, and it’s important for people to understand their options—even those who are employed and consistently had access to insurance through work. We want to know what their concerns are so we can help patients and survivors. Getting healthcare should not be a worry for cancer survivors.”

“Survivors have been through a lot when they were younger and understand the importance of making sure they can get healthcare when they need it. I think a lot of them also saw what their parents and families went through in terms of the financial stress and burden of dealing with a health crisis. So they’re just primed to understand the importance of health insurance.”

Dr Kirchhoff noted that this study was conducted as the Affordable Care Act was rolling out. Therefore, she would like to do a follow-up study to see if the insurance exchanges and Medicaid expansion lessened job-related insurance worries.

The US Food and Drug Administration (FDA) has granted breakthrough therapy designation to MOR208, an Fc-enhanced monoclonal antibody directed against CD19.

The designation is for MOR208 to be used in combination with lenalidomide to treat adults with relapsed or refractory diffuse large B-cell lymphoma (DLBCL) who are not eligible for high-dose chemotherapy and autologous stem cell transplant.

The FDA’s breakthrough designation is intended to expedite the development and review of new treatments for serious or life-threatening conditions.

The designation entitles the company developing a therapy to more intensive FDA guidance on an efficient and accelerated development program, as well as eligibility for other actions to expedite FDA review, such as rolling submission and priority review.

To earn breakthrough designation, a treatment must show encouraging early clinical results demonstrating substantial improvement over available therapies with regard to a clinically significant endpoint, or it must fulfill an unmet need.

The breakthrough designation for MOR208 is based on preliminary data from the ongoing phase 2 L-MIND study (NCT02399085).

In this trial, researchers are evaluating MOR208 in combination with lenalidomide in patients with relapsed/refractory DLBCL who are ineligible for high-dose chemotherapy and autologous stem cell transplant.

Preliminary data from this trial were presented at ASCO 2017.* Of the 44 patients enrolled at the data cut-off, 34 were evaluable for efficacy.

The objective response rate was 56% (19/34), and the complete response rate was 32% (11/34). Sixteen of the 19 responders were still on study at the data cut-off point.

The most frequent adverse events of grade 3 or higher were neutropenia (32%), thrombocytopenia (9%), and leukopenia (9%). As of the data cut-off, 27% of patients required a reduction of the lenalidomide dose due to side effects.

“We expect to report further data from our ongoing phase 2 L-MIND trial with MOR208 plus lenalidomide at this year’s American Society of Hematology conference in December,” said Malte Peters, chief development officer of MorphoSys AG, the company developing MOR208.

“In addition, we are currently evaluating MOR208 in combination with bendamustine in our phase 3 B-MIND trial.”

The B-MIND study is designed to compare MOR208 plus bendamustine to rituximab plus bendamustine in patients with relapsed/refractory DLBCL who are not eligible for high-dose chemotherapy and autologous stem cell transplant.

A patient with Merkel cell carcinoma (MCC) came to Sir Charles Gairdner Hospital in Perth, Australia, after 2 weeks of dyspnea. He was diagnosed with cardiac tamponade and received urgent pericardiocentesis. An echocardiogram and computer tomography scan showed a large infiltrating mass in the heart. Immunohistochemistry of the pericardial fluid revealed MCC. The MCC had metastasized to his heart—the tenth such reported case, and the second case reported of MCC causing cardiac tamponade.

The clinicians report on several “important illustrative aspects” that appeared while they were unraveling the clues to the patient’s condition. One aspect was the challenge of the histopathologic diagnosis itself. The majority of patients with MCC present with localized disease, they note. Only 4% of patients have distant metastases, usually to lymph nodes, lung, central nervous system, and bone. MCC metastases to the heart are extremely rare. Most commonly, a cancer that spreads to the heart has started in the lungs, esophagus, or breast, or has begun as lymphoma, melanoma, or leukemia.  

However, it’s “exponentially more likely,” the clinicians say, for a cardiac tumor to be a metastasis than a primary cardiac tumor, and it is uncommon for the heart to be the only site of metastatic disease from a noncardiac malignancy. Thus, the patient represented a unique case: apart from an internal mammary lymph node, the heart was the only site of distant metastatic spread.  

This patient’s case highlights the importance of early and accurate diagnosis of MCC with aggressive surgical treatment for localized disease, the clinicians say. New cardiac symptoms in the setting of malignancy should raise suspicion of cardiac metastasis.

New research indicates that hospitalized patients with advanced cancer have a high burden of physical and psychological symptoms, and this burden is linked to longer hospital stays and a greater risk for unplanned hospital readmissions and death.

Researchers said these findings highlight the need to develop and test interventions to lessen patients’ symptoms.

Ryan Nipp, MD, of Massachusetts General Hospital in Boston, and his colleagues reported the findings in Cancer.

The researchers noted that patients with advanced cancer often experience frequent and prolonged hospitalizations for reasons that have not been fully explored.

To investigate, the team collected information from 1036 patients with advanced cancer as they were being admitted for an unplanned hospitalization.

The Edmonton Symptom Assessment System (ESAS) was used to assess patients’ physical symptoms, and the Patient Health Questionnaire 4 (PHQ-4) was used to assess their psychological symptoms.

The researchers examined the relationship between patients’ symptom burden and the duration of their hospital stay, risk of readmission, and death.

Many patients reported moderate or severe fatigue (86.7%), poor well-being (74.2%), drowsiness (71.7%), pain (67.7%), and lack of appetite (67.3%). Nearly 30% of patients had clinically significant symptoms of depression (28.8%) and anxiety (28.0%).

The patients’ mean hospital stay was 6.3 days, the readmission rate within 90 days of discharge was 43.1%, and the 90-day mortality rate was 41.6%.

Physical symptoms (P<0.001), total ESAS score (P<0.001), total PHQ-4 score (P=0.040), and depression symptoms (P=0.017) were significantly associated with longer hospital stays, but anxiety symptoms were not (P=0.190).

Physical symptoms (P<0.001), total ESAS score (P<0.001), total PHQ-4 score (P=0.072), and anxiety symptoms (P=0.045) were significantly associated with a higher likelihood of readmission within 90 days, but depression symptoms were not (P=0.219).

Physical symptoms (P<0.001), total ESAS score (P<0.001), total PHQ-4 score (P<0.001), depression symptoms (P<0.001), and anxiety symptoms (P=0.012) were all significantly associated with a higher likelihood of death or readmission within 90 days.

“We demonstrated that many hospitalized patients with advanced cancer experience an immense physical and psychological symptom burden,” Dr Nipp said.

“Interventions to identify and treat symptomatic patients hold great potential for improving patients’ experience with their illness, enhancing their quality of life, and reducing their healthcare utilization.”

New research indicates that hospitalized patients with advanced cancer have a high burden of physical and psychological symptoms, and this burden is linked to longer hospital stays and a greater risk for unplanned hospital readmissions and death.

Researchers said these findings highlight the need to develop and test interventions to lessen patients’ symptoms.

Ryan Nipp, MD, of Massachusetts General Hospital in Boston, and his colleagues reported the findings in Cancer.

The researchers noted that patients with advanced cancer often experience frequent and prolonged hospitalizations for reasons that have not been fully explored.

To investigate, the team collected information from 1036 patients with advanced cancer as they were being admitted for an unplanned hospitalization.

follicular lymphoma

The European Medicines Agency’s (EMA’s) Committee for Orphan Medicinal Products has recommended orphan designation for G100 for the treatment of follicular lymphoma (FL).

G100 contains the synthetic small molecule toll-like receptor-4 agonist glucopyranosyl lipid A.

G100 works by activating innate and adaptive immunity in the tumor microenvironment to generate an immune response against the tumor’s pre-existing antigens.

Clinical and preclinical data have demonstrated G100’s ability to activate tumor-infiltrating lymphocytes, macrophages, and dendritic cells, and promote antigen-presentation and the recruitment of T cells to the tumor.

The induction of local and systemic immune responses has been shown in preclinical studies to result in local and abscopal tumor control.

Immune Design, the company developing G100, is currently evaluating G100 plus local radiation, with or without pembrolizumab, in a phase 1/2 trial of FL patients.

Results from this trial were presented at the 2017 ASCO Annual Meeting (abstract 7537). Nine patients who received G100 (3 patients each at the 5, 10, or 20 μg dose) with radiation (but not pembrolizumab) were evaluable for safety and efficacy.

The overall response rate was 44%, and all of these were partial responses (n=4). Thirty-three percent of patients had stable disease (n=3).

Among the responders, tumor regression ranged from 58% to 89%, which included up to 56% shrinkage of abscopal sites. Tumor biopsies showed increased inflammatory responses and T-cell infiltrates in abscopal tumors.

An additional 13 patients treated at the 10 μg dose were evaluable for safety.  There were no dose-limiting toxicities, serious adverse events (AEs), or grade 3/4 AEs observed.

Common AEs included injection site disorders, abdominal pain/discomfort, nausea, pruritus, and decrease in lymphocytes.

Immune Design said that, if this trial produces a sufficiently robust clinical benefit for patients, the company may pursue FL as the first indication for regulatory approval of G100.

About orphan designation

Orphan designation provides regulatory and financial incentives for companies to develop and market therapies that treat life-threatening or chronically debilitating conditions affecting no more than 5 in 10,000 people in the European Union, and where no satisfactory treatment is available.

Orphan designation provides a 10-year period of marketing exclusivity if the drug receives regulatory approval.

The designation also provides incentives for companies seeking protocol assistance from the EMA during the product development phase and direct access to the centralized authorization procedure.

The EMA’s Committee for Orphan Medicinal Products adopts an opinion on the granting of orphan drug designation, and that opinion is submitted to the European Commission for a final decision. The commission typically makes a decision within 30 days of the submission.

In elderly patients with aggressive B-cell lymphomas who experience treatment failure after CHOP or rituximab-CHOP (R-CHOP), the outcomes of subsequent salvage therapy were improved when rituximab was included, results of a retrospective analysis suggest.

“Survival after rituximab-containing salvage therapy was better in all patient groups, supporting the repeated administration of rituximab to all patients needing salvage therapy,” wrote investigator Bertram Glass, MD, of the department of hematology and stem cell transplantation at Helios Klinikum Berlin-Buch, Berlin, and his coauthors (Ann Oncol. 2017 Oct 6. doi: 10.1093/annonc/mdx556).

Dr. Glass and colleagues reviewed data from the randomized RICOVER-60 trial, which included 1,222 patients aged 61-80 years with aggressive B-cell lymphomas who received CHOP or R-CHOP for six or eight cycles. Based on survival outcomes, six cycles of R-CHOP every 2 weeks should be the preferred regimen, investigators wrote when the study results were published in 2008 (Lancet Oncol. 2008;9[2]:105-16. doi: 10.1016/S1470-2045(08)70002-0).

Of 1,222 patients in the RICOVER-60 trial, 301 (24.6%) had treatment failure, of whom 297 could be included in the present analysis.

Rituximab, included in salvage therapy for 57.4% of those evaluable patients, was found to improve the 2-year survival rate from 20.7% to 46.8% (P less than .001), Dr. Glass and his coinvestigators reported.

The benefit of rituximab in the salvage setting was apparent regardless of whether patients received R-CHOP or CHOP as part of their initial therapy in RICOVER-60, they added.

Among patients who had received CHOP as first-line therapy, 2-year overall survival was 49.6% for those who received rituximab in the salvage setting, compared with 19.1% for those who did not (P less than .001), according to the published data. Likewise, in the initial R-CHOP group, 2-year overall survival was 33.1% for rituximab in salvage and 22.5% for no rituximab in salvage (P = .034).

The investigators also looked for differences in prognosis according to specific patient characteristics, including presence of MYC rearrangements and MYC expression by immunohistochemistry.

In patients with MYC translocation at diagnosis, use of rituximab reduced risk of initial treatment failure from 58.8% to 26.3%, according to the investigators. After treatment failure, patients who initially received CHOP had significantly improved 2-year survival if they had MYC translocations or negative MYC immunohistochemistry, though no such association was found for patients who initially received R-CHOP, they wrote.

Dr. Glass and colleagues concluded that new treatment strategies are needed.

“Overall, the outcome of second-line treatment of elderly patients with refractory and relapsed aggressive B-cell lymphoma is disappointing and worse than in younger patients regardless of the modality chosen,” they wrote. “New drugs and treatment modalities with the potential to change the dismal outlook for elderly patients with aggressive B-cell lymphomas are eagerly awaited.”

Dr. Glass and several coauthors reported honoraria, research funding, and consultancies with Roche.

As preparation for autologous stem cell transplantation, total-body irradiation was as safe and effective as chemotherapy conditioning, in a retrospective analysis of mantle cell lymphoma patient records.

“Our data suggest that both TBI [total-body irradiation] and BEAM [carmustine, etoposide, cytarabine, and melphalan]-based conditioning regimens remain viable conditioning options for MCL patients undergoing ASCT [autologous stem cell transplantation],” wrote Yolanda D. Tseng, MD, of the University of Washington, Seattle, and her coinvestigators.

Progression-free survival, the primary outcome, was greater at 5 years’ follow-up in 43 TBI patients (66%) than in the 32 chemotherapy-conditioned patients (52%), but the difference did not reach statistical significance. Overall survival followed a similar pattern: TBI patients’ overall survival at 5 years was 82%, compared with 68% in the TBI patients, but this difference also lacked significance (Biol Blood Marrow Transplant. 2017 Oct 20; doi: 10.1016/j.bbmt.2017.10.029).

Safety outcomes, including early toxicity, nonrelapse mortality, and secondary malignancies, also were similar between groups.

For the analysis, Dr. Tseng and her colleagues reviewed the records of 75 consecutive adult patients treated during 2001-2011 with ASCT at the Fred Hutchinson Cancer Research Center in Seattle. All underwent conditioning with either myeloablative TBI or a BEAM-based regimen.

Most of the patients had chemosensitive disease (97%), and nearly all received rituximab prior to ASCT.

Prior studies have shown that TBI can be at least as effective as chemotherapy conditioning, but none have looked at toxicity. These results indicate that either approach remains viable for patients undergoing ASCT for MCL, Dr. Tseng and her colleagues concluded.

Micrograph showing DLBCL

A new assay may help improve the diagnosis and treatment of diffuse large B-cell lymphoma (DLBCL), according to researchers.

The gene expression signature assay can be used to classify subtypes of DLBCL and may enhance disease management by helping to match tumors with the appropriate targeted therapy.

Researchers described the assay in the Journal of Molecular Diagnostics.

The assay is a novel gene expression profiling DLBCL classifier based on reverse transcriptase multiplex ligation-dependent probe amplification (RT-MLPA).

It can simultaneously evaluate the expression of 21 markers, allowing differentiation of the 3 subtypes of DLBCL—germinal center B-cell-like (GCB), activated B-cell-like (ABC), and primary mediastinal B-cell lymphoma (PMBL)—as well as other individualized disease characteristics, such as Epstein-Barr infection status.

Researchers used the RT-MLPA assay to test 150 samples from DLBCL patients. Forty-two percent of the samples were the ABC subtype, 37% the GCB subtype, and 10% molecular PMBL. Eleven percent of the samples could not be classified.

Overall, the RT-MLPA assay correctly assigned 85.0% of the cases into the expected subtypes, compared to 78.8% of samples assigned via immunohistochemistry.

The RT-MLPA assay was also able to detect the MYD88 L265P mutation, one of the most common genetic abnormalities found in ABC DLBCLs. This information can influence treatment, since the presence of the mutation is thought to be predictive of ibrutinib sensitivity.

The researchers said RT-MLPA is a robust, efficient, rapid, and cost-effective alternative to current methods used in the clinic to establish the cell-of-origin classification of DLBCLs.

RT-MLPA requires only common laboratory equipment and can be applied to formalin-fixed, paraffin-embedded samples. Other types of diagnostic methods may not provide the level of detail needed and may also be limited by poor reproducibility and lack of adaptability to routine use in standard laboratories.

“Because we have provided the classification algorithms, other laboratories will be able to verify our results and adjust the procedures to suit their environment,” said study author Philippe Ruminy, PhD, of the Henri Becquerel Cancer Treatment Center, INSERM U1245 in Rouen, France.

“It is our hope that the assay we have developed, which addresses an important recommendation of the recent WHO classifications, will contribute to better management of these tumors and improved patient outcomes.”

It can simultaneously evaluate the expression of 21 markers, allowing differentiation of the 3 subtypes of DLBCL—germinal center B-cell-like (GCB), activated B-cell-like (ABC), and primary mediastinal B-cell lymphoma (PMBL)—as well as other individualized disease characteristics, such as Epstein-Barr infection status.

Researchers used the RT-MLPA assay to test 150 samples from DLBCL patients. Forty-two percent of the samples were the ABC subtype, 37% the GCB subtype, and 10% molecular PMBL. Eleven percent of the samples could not be classified.

Overall, the RT-MLPA assay correctly assigned 85.0% of the cases into the expected subtypes, compared to 78.8% of samples assigned via immunohistochemistry.

The RT-MLPA assay was also able to detect the MYD88 L265P mutation, one of the most common genetic abnormalities found in ABC DLBCLs. This information can influence treatment, since the presence of the mutation is thought to be predictive of ibrutinib sensitivity.

The researchers said RT-MLPA is a robust, efficient, rapid, and cost-effective alternative to current methods used in the clinic to establish the cell-of-origin classification of DLBCLs.

RT-MLPA requires only common laboratory equipment and can be applied to formalin-fixed, paraffin-embedded samples. Other types of diagnostic methods may not provide the level of detail needed and may also be limited by poor reproducibility and lack of adaptability to routine use in standard laboratories.

“Because we have provided the classification algorithms, other laboratories will be able to verify our results and adjust the procedures to suit their environment,” said study author Philippe Ruminy, PhD, of the Henri Becquerel Cancer Treatment Center, INSERM U1245 in Rouen, France.

“It is our hope that the assay we have developed, which addresses an important recommendation of the recent WHO classifications, will contribute to better management of these tumors and improved patient outcomes.”

A new assay may help improve the diagnosis and treatment of diffuse large B-cell lymphoma (DLBCL), according to researchers.

The gene expression signature assay can be used to classify subtypes of DLBCL and may enhance disease management by helping to match tumors with the appropriate targeted therapy.
