Oral voxelotor improves hemoglobin in sickle cell disease
AMSTERDAM – The investigational oral agent voxelotor induced rapid and sustained improvements in hemoglobin and hemolysis in both children and adults with sickle cell disease (SCD), follow-up results from the phase 3 HOPE trial show.
Among 274 patients aged 12-59 years, those who were randomly assigned to receive voxelotor at a dose of 1,500 mg daily had significantly better hemoglobin responses – defined as an increase of more than 1.0 g/dL from baseline – than did patients assigned to placebo, reported Jo Howard, MD, of Guy’s and St. Thomas’ NHS Foundation Trust and King’s College in London.
“. This has the potential to reduce the morbidity in sickle cell disease and to improve the life of our patients,” she said at a briefing prior to her presentation of the data at the annual congress of the European Hematology Association.
There were no new safety signals and patients tolerated voxelotor well, she added.
The study was published simultaneously in the New England Journal of Medicine.
Voxelotor is a novel oral agent that increases hemoglobin’s affinity for oxygen by inhibiting hemoglobin polymerization and sickling of red blood cells, which if unchecked lead to serious consequences, such as chronic anemia and hemolysis, and subsequent organ damage, vaso-occlusion, stroke, or premature death.
In the HOPE (Hemoglobin Oxygen Affinity Modulation to Inhibit HbS Polymerization) trial, investigators enrolled 274 adolescents and adults with SCD and randomized them on a 1:1:1 basis to receive voxelotor at doses of either 1,500 mg or 900 mg daily, or placebo.
Approximately two-thirds of the patients were receiving hydroxyurea at baseline.
In a per-protocol analysis, 59.5% of patients who received the 1,500-mg dose of voxelotor had a hemoglobin response (P less than .001 compared with baseline), as did 38% of patients in the 900-mg group (P less than .001). Among patients assigned to placebo, however, just 9.2% had a hemoglobin response, a difference that was not statistically significant.
In an intention-to-treat analysis, in which patients who did not complete the study were considered to be nonresponders, the respective rates of hemoglobin response were 51.1%, 32.6%, and 6.5%.
The difference between the 1,500-mg dose and placebo was significant (P less than .001). The difference between the 900-mg group and placebo was not statistically significant.
Hemoglobin levels of 10 g/dL or higher at week 24 were seen in 41% of the participants in the 1,500-mg group, 20% in the 900-mg group, and 9% in the placebo group.
Patients on voxelotor had an improvement in hemoglobin, whether or not they were on hydroxyurea, and those with hemoglobin either below or above 7 g/dL at baseline all had an increase in hemoglobin.
The annualized adjusted incidence rate of vaso-occlusive crises was similar in the two voxelotor groups (2.77 for the 1,500-mg dose and 2.76 for the 900-mg group) – both lower than in the placebo group (3.19).
Among patients who had two or more vaso-occlusive crises within the previous year, the respective annualized incidence rates were 2.88, 3.39, and 3.50.
There was a trend toward reduced incidence of crises with voxelotor over time, Dr. Howard said.
Grade 3 or greater adverse events occurred in 26% of patients in the 1,500-mg group, 23% in the 900-mg group, and 26% in the placebo group. The most common adverse events were headache and diarrhea.
“The data presented support the achievement of the stated primary endpoint in the HOPE trial, which was to reduce anemia and hemolysis. The hemoglobin response and reduction in hemolysis observed with an orally administered, once-daily medication with side effects that minimally affect lifestyle may make voxelotor a promising advancement in the management of sickle cell disease if approved by the [Food and Drug Administration],” Alexis Thompson, MD, MPH, of Northwestern University, Chicago, noted in an editorial accompanying the study in the New England Journal of Medicine.
Global Blood Therapeutics funded the study. Dr. Howard reported consultant/advisory board activity for the company. Dr. Thompson reported grants and/or personal fees from other companies.

Survival exceeds 90% in transplant for SCD
FORT LAUDERDALE, FLA. — A multicenter pilot study of a prophylactic regimen for both matched sibling donor and unrelated donor bone marrow transplantation in adults with severe sickle cell disease has found similar overall and event-free survival rates between the two approaches, exceeding 90% and 85%, respectively, at one year, according to preliminary results presented at the annual meeting of the Foundation for Sickle Cell Disease Research.
The results have led to a Phase 2 single-arm, multicenter trial, known as STRIDE , to evaluate a reduced toxicity preparative regimen consisting of busulfan (13.2 mg/kg), fludarabine (175 mg/m 2 ) and antithymocyte globulin (ATG, 6 mg/kg) and cyclosporine or tacrolimus and methotrexate for graft-vs-host disease (GVHD) prophylaxis in adults with sickle cell disease (SCD), said Lakshmanan Krishnamurti, MD, of Children’s Healthcare of Atlanta/Emory University. “The data are similar with 91% overall survival and 86% event-free survival,” he said.
The pilot study, published recently ( Am J Hematol. 2019;94:446-54 ), indicated the effectiveness of non-myeloablative conditioning in SCD patients with matched-sibling bone marrow transplant (BMT), with a higher intensity regimen of busulfan/fludarabine/ATG effective in unrelated donor BMT for other conditions, Dr. Krishnamurti said.
The pilot study also found that three-year event-free survival (EFS) of 82%, and statistically significant improvements in pain and health-related quality of life.
STRIDE is the first comparative study of BMT vs. standard of care in severe SCD, Dr. Krishnamurti added. The primary endpoint is overall survival at two years after biologic assignment, with longer-term outcomes including survival at three to 10 years post-hematopoietic stem cell transplantation (HSCT), and impact of BMT on sickle-related events, organ function, health-related quality of life and chronic pain.
The pilot study included 22 patients between the ages of 17 and 36 who had BMT at eight centers. Seventeen patients received marrow from a sibling-matched donor and five patients received marrow from an unrelated donor.
Dr. Krishnamurti referenced a recent study out of France that showed chimerism levels after transplant may be a determining physiological factor for outcomes (Haematologica. doi:10.3324/haematol.2018.213207 ). “So if chimerism is stable, somewhere in the 25% to 50% or better range, and hemoglobin levels are improved, this decrease hemolysis,” he said. “This is very important in understanding how to manage these patients.”
That study showed that rates of chronic GVHD up to 10 years post-transplant have steadily improved over the past three decades in patients with SCD who’ve had BMT, Dr. Krishnamurti noted. “But chronic GVHD is higher in patients age 16 to 30 vs. patients 15 and younger,” he said, “so that’s the reason to consider transplantation sooner in patients who have a matched sibling donor.”
The French study shows that BMT with sibling-matched donors has excellent outcomes in young children, Dr. Krishnamurti said. “Outcomes for adults with transplantation is becoming similar to that in children,” he added. “Age is an important predictor of outcomes and the risk for progressive morbidity-impaired quality of life and risk of mortality still exists in adults with sickle cell disease.”
The bottom line, he said, is that patients and caregivers must be given the opportunity to consider transplantation as an option at younger ages.
Dr. Krishnamurti did not disclose any financial relationships.

FDA: Faulty hematology analyzers face class I recall
The Food and Drug Administration is alerting laboratories and providers to a class I recall on Beckman Coulter hematology analyzers because of the potential for inaccurate platelet count results.
A class I recall indicates reasonable probability of serious adverse health consequences or death associated with use, according to the FDA.
The recall is related to the devices’ platelet analyzing function; among other uses, these devices help assess patients fitness for surgery, so a faulty reading on platelet counts could result in increased risk for life-threatening bleeding during a procedure in patients who have unidentified severe thrombocytopenia, according to a statement from the agency.
“Because this may cause serious injury, or even death, to a patient, we are urging health care professionals to be aware of the potential for inaccurate diagnostic results with these analyzers and to take appropriate actions including the use of alternative diagnostic testing or confirming analyzer results with manual scanning or estimate of platelets,” Tim Stenzel, MD, PhD, director of the Office of In Vitro Diagnostics and Radiological Health in the FDA’s Center for Devices and Radiological Health, said in the statement.
The recall applies to the UniCel DxH 800 Coulter Cellular Analysis System, UniCel DxH 600 Coulter Cellular Analysis System, and UniCel DxH 900 Coulter Cellular Analysis System. The faulty devices were first identified in 2018, and the manufacturer released an urgent medical device correction letter at that time. The company has more recently released a software patch for the devices, but the FDA has not yet assessed whether it resolves the problem. The agency has released detailed actions and recommendations related to these devices.
At this time, the FDA is unaware of any serious adverse events that have been directly linked to these devices, but the agency recommends that any events be reported through its MedWatch reporting system.

Peanut contamination risk prompts Promacta recall
Novartis has recalled three lots of 12.5-mg eltrombopag (Promacta) for oral suspension following discovery of possible contamination with peanut flour at a third-party manufacturing site.
Tablets at doses of 12.5 mg, 25 mg, 50 mg, and 75 mg are unaffected by this recall because they are not manufactured in the same facility. The recalled lots of medication were distributed between January and April 2019, but so far, Novartis has not received any reports of adverse events related to the recall.
Oral suspension of eltrombopag is indicated for certain patients with chronic immune thrombocytopenia, hepatitis C–associated thrombocytopenia, and severe aplastic anemia.
More information on the recalled lots and instructions on how to return the product can be found in the full announcement, which is also available through the Food and Drug Administration website.

Gabapentin falls short in treating sickle cell pain
NEW ORLEANS – Adding gabapentin to standard therapy did not significantly reduce vaso-occlusive pain in most patients with sickle cell disease enrolled in a phase 2 trial.
In the entire cohort, there were no significant differences in pain response between patients who received gabapentin and those who received placebo. However, patients with the HbSS genotype had a significantly greater decrease in pain score from baseline to discharge if they received gabapentin rather than placebo.
Additional studies are needed to confirm these findings because this trial was limited by a small sample size, according to study investigator Latika Puri, MD, of St. Jude Children’s Research Hospital in Memphis. Dr. Puri presented the trial at the annual meeting of the American Society of Pediatric Hematology/Oncology.
The trial included 86 evaluable patients who had vaso-occlusive pain and a pain score of at least 4. All patients received standard therapy for vaso-occlusive pain and were randomized to receive placebo (n = 44) or a single oral dose of gabapentin at 15 mg/kg (n = 42).
Baseline characteristics were similar between the treatment arms. For the entire cohort, the mean age was 11.8 years (range, 1-21 years), and 51% of patients were male. Forty-four patients had the HbSS genotype, 25 had the HbSC genotype, 8 had HbS/beta0-thalassemia, and 9 had other genotypes.
The mean pain score at baseline was 7.8 for the entire cohort, 8.0 for the gabapentin arm, and 7.7 for the placebo arm.
For the entire cohort, there was no significant difference in pain response between the gabapentin and placebo arms.
The proportion of patients who experienced a greater than 33% decrease in pain from baseline to 3 hours posttreatment was 67% in the gabapentin arm and 59% in the placebo arm (P = .23). The proportion of patients who experienced a greater than 33% decrease from baseline to discharge from the acute care clinic was 75% and 61%, respectively (P = .18).
In the entire cohort, decreases in pain scores from baseline to 3 hours posttreatment were not significantly different between the gabapentin and placebo arms, at 1.3 and 0.7, respectively (P = .74). Likewise, decreases in pain scores from baseline to discharge were not significantly different, at 1.6 and 0.8 (P = .38).
Among patients who had the HbSS genotype, there was a significantly greater decrease in pain score from baseline to discharge in the gabapentin arm than in the placebo arm, 5.9 versus 3.6 (P = .03). However, there were no other significant differences in pain response for the HbSS subgroup.
There were no significant differences in opioid consumption or hospitalization for the HbSS subgroup or the entire cohort. For the entire cohort, the mean morphine equivalent dose from baseline to 3 hours posttreatment was 0.16 mg/kg in the gabapentin arm and 0.17 mg/kg in the placebo arm (P = .89). For the HbSS subgroup, the mean dose was 0.16 mg/kg and 0.15 mg/kg, respectively (P = .93).
In the entire cohort, 24% of patients in the gabapentin arm and 27% of those in the placebo arm were hospitalized (P = .71). In the HbSS subgroup, hospitalizations occurred in 11% and 35% (P = .15).
Dr. Puri pointed out several challenges that led to limitations in this study. Specifically, the investigators had to obtain patient consent while delivering standard treatment, while patients were in pain and distress, and from patients who had already received opioids and were sleepy. Additionally, gabapentin had to be delivered within 1 hour of opioid administration, and a lack of after-hours staff limited enrollment.
“These challenges led to one of our biggest limitations, which was a small sample size, leading to a limited power to observe real differences,” Dr. Puri said. “We also defined a very short time period of evaluation for the primary outcomes; that was 3 hours from the gabapentin dose or placebo dose. This limited our capability to see real differences if they existed.”
Dr. Puri said additional studies with larger sample sizes are needed to confirm these findings. She added that efforts to better characterize pain in sickle cell disease could reveal patients who may benefit from gabapentin because they have a neuropathic component to their pain.
The trial was sponsored by St. Jude Children’s Research Hospital in collaboration with Scan|Design Foundation. Dr. Puri did not provide disclosure information at the meeting.

NEW ORLEANS – Adding gabapentin to standard therapy did not significantly reduce vaso-occlusive pain in most patients with sickle cell disease enrolled in a phase 2 trial.
In the entire cohort, there were no significant differences in pain response between patients who received gabapentin and those who received placebo. However, patients with the HbSS genotype had a significantly greater decrease in pain score from baseline to discharge if they received gabapentin rather than placebo.
Additional studies are needed to confirm these findings because this trial was limited by a small sample size, according to study investigator Latika Puri, MD, of St. Jude Children’s Research Hospital in Memphis. Dr. Puri presented the trial at the annual meeting of the American Society of Pediatric Hematology/Oncology.
The trial included 86 evaluable patients who had vaso-occlusive pain and a pain score of at least 4. All patients received standard therapy for vaso-occlusive pain and were randomized to receive placebo (n = 44) or a single oral dose of gabapentin at 15 mg/kg (n = 42).
Baseline characteristics were similar between the treatment arms. For the entire cohort, the mean age was 11.8 years (range, 1-21 years), and 51% of patients were male. Forty-four patients had the HbSS genotype, 25 had the HbSC genotype, 8 had HbS/beta0-thalassemia, and 9 had other genotypes.
The mean pain score at baseline was 7.8 for the entire cohort, 8.0 for the gabapentin arm, and 7.7 for the placebo arm.
For the entire cohort, there was no significant difference in pain response between the gabapentin and placebo arms.
The proportion of patients who experienced a greater than 33% decrease in pain from baseline to 3 hours posttreatment was 67% in the gabapentin arm and 59% in the placebo arm (P = .23). The proportion of patients who experienced a greater than 33% decrease from baseline to discharge from the acute care clinic was 75% and 61%, respectively (P = .18).

LentiGlobin reduces transfusion dependence in young thalassemia patients
NEW ORLEANS – The gene therapy LentiGlobin can reduce transfusion dependence in children and young adults with non-beta0/beta0 thalassemia, according to two trials.
In a phase 1/2 trial, 8 of 10 of patients achieved transfusion independence at a median follow-up of 36.0 months. In a phase 3 trial, transfusion independence was achieved by 2 of 3 patients with follow-up of at least 12 months.
Timothy S. Olson, MD, PhD, of Children’s Hospital of Philadelphia, presented results from the phase 1/2 HGB-204 trial and the phase 3 HGB-207 trial at the annual meeting of the American Society of Pediatric Hematology/Oncology.
Treatment
In both trials, patients received granulocyte colony-stimulating factor and plerixafor for hematopoietic stem cell mobilization. Their cells were collected via apheresis and transduced with the betibeglogene darolentivec (BB305) lentiviral vector. The patients received busulfan (for an average of 4 days) as conditioning and were infused with the transduced cells.
The manufacturing process for LentiGlobin was refined in the HGB-207 trial, which translated to a product with a higher vector copy number and higher proportion of CD34+ cells transduced, Dr. Olson said.
The median vector copy number was 3.1 in the HGB-207 trial and 0.7 in the HGB-204 trial. The median proportion of CD34+ cells transfused was 81% and 29%, respectively. The median cell dose was 7.7 x 106 CD34+ cells/kg and 7.1 x 106 CD34+ cells/kg, respectively.
HGB-204 patients and efficacy
The HGB-204 trial included 10 patients with non-beta0/beta0 genotypes – 6 with betaE/beta0, 1 with beta+/beta0, 2 with beta+/beta+, and 1 with an “other” genotype.
The patients’ median age at consent was 19.5 years (range, 16-34). The annualized median prestudy red blood cell (RBC) transfusion volume was 151 mL/kg per year.
At a median follow-up of 36 months, 8 of the 10 patients achieved transfusion independence. The median duration of transfusion independence was 38 months. The median weighted average hemoglobin during transfusion independence was 10.2 g/dL.
“Two patients did not achieve transfusion independence, and both patients were on the lower end of the spectrum both in terms of vector copy number per cell and the percentage of CD34+ cells that were successfully transduced,” Dr. Olson said. “Both patients actually experienced a reduction in the annualized transfusion volume requirements of between 43% and 77%.”
HGB-207 patients and efficacy
The HGB-207 trial included 16 patients with non-beta0/beta0 genotypes – 6 with betaE/beta0, 7 with beta+/beta0, and 3 with the beta+/beta+ genotype.
The patients’ median age at consent was 19 years . The annualized median prestudy RBC transfusion volume was 192 mL/kg per year.
The median follow-up in this trial is 9.3 months. Ten of 11 patients with at least 3 months of follow-up are transfusion-free with hemoglobin levels greater than 11 g/dL.
Two patients have achieved transfusion independence according to the protocol definition, which is weighted average hemoglobin of 9 g/dL or greater without any RBC transfusions for at least 12 months.
“In the one patient in this study who did not achieve transfusion independence, the vector-derived hemoglobin was quite low, and this correlated with a very low vector copy number seen in circulating peripheral blood mononuclear cells,” Dr. Olson said.
It isn’t clear why this occurred, however, as the vector copy number wasn’t especially low in the LentiGlobin product the patient received. Therefore, the researchers are still investigating why this patient failed to achieve transfusion independence.
Safety in both trials
“Very importantly, there were no deaths, there were no engraftment failures, there was no evidence of vector-mediated replication-competent lentivirus, and integration site analysis revealed no evidence of clonal dominance,” Dr. Olson said.
He added that most of the grade 3 or greater adverse events seen in both trials were directly attributable to busulfan-based myeloablative conditioning, including four episodes of veno-occlusive disease.
Nonhematologic grade 3 or higher adverse events in HGB-204 included stomatitis (n = 8), febrile neutropenia (n = 6), irregular menstruation (n = 3), pharyngeal inflammation (n = 2), and veno-occlusive liver disease (n = 1).
Nonhematologic grade 3 or higher adverse events in HGB-207 included stomatitis (n = 9), febrile neutropenia (n = 4), pharyngeal inflammation (n = 2), epistaxis (n = 3), pyrexia (n = 3), veno-occlusive liver disease (n = 3), ALT increase (n = 2), bilirubin increase (n = 2), and hypoxia (n = 2).
One patient in HGB-207 had grade 3 thrombocytopenia considered possibly related to LentiGlobin.
Dr. Olson reported advisory board engagement with bluebird bio, which sponsored both trials.

CDC warns against misuse of opioid-prescribing guideline
Officials at the Centers for Disease Control and Prevention are warning against the misapplication of the agency’s 2016 guidelines on opioid prescribing, as well as clarifying dosage recommendations for patients starting or stopping pain medications.
In a perspective published in the New England Journal of Medicine on April 24, lead author Deborah Dowell, MD, chief medical officer for the CDC’s National Center for Injury Prevention and Control, conveyed concern that some policies and practices derived from the 2016 CDC Guideline for Prescribing Opioids for Chronic Pain are inconsistent with the recommendations and often go beyond their scope.
Misapplication examples include inappropriately applying the guideline to patients in active cancer treatment, patients experiencing acute sickle cell crises, or patients experiencing postsurgical pain, Dr. Dowell wrote.
The guideline offers guidance to clinicians treating chronic pain in adults who are already receiving opioids long-term at high dosages, she noted. It includes advice on maximizing nonopioid treatment, reviewing risks associated with continuing high-dose opioids, and collaborating with patients who agree to taper dosage, among other guidance.
Any application of the guideline’s dosage recommendation that results in hard limits or “cutting off” opioids is also an incorrect use of the recommendations, according to Dr. Dowell.
While the guideline advises clinicians to start opioids at the lowest effective dosage and avoid increasing dosage to 90 morphine milligram equivalents per day or more, that statement does not suggest discontinuation of opioids already prescribed at high dosages, according to the CDC’s clarification.
The guidance also does not apply to patients receiving or starting medication-assisted treatment for opioid use disorder.
The commentary comes after a trio of organizations raised concerns that insurers are inappropriately applying the recommendations to active cancer patients when making coverage determinations.
The American Society of Clinical Oncology, the National Comprehensive Cancer Network, and the American Society of Hematology, raised the issue in a letter to the CDC in February. In response, Dr. Dowell clarified that the recommendations are not intended to deny clinically appropriate opioid therapy to any patients who suffer chronic pain, but rather to ensure that physicians and patients consider all safe and effective treatment options.
In the perspective, Dr. Dowell wrote that the CDC is evaluating the intended and unintended impact of the 2016 opioid-prescribing guideline on clinician and patient outcomes and that the agency is committed to updating the recommendations when new evidence is available.

In response, Dr. Dowell clarified that the recommendations are not intended to deny clinically appropriate opioid therapy to any patients who suffer chronic pain, but rather to ensure that physicians and patients consider all safe and effective treatment options.
In the perspective, Dr. Dowell wrote that the CDC is evaluating the intended and unintended impact of the 2016 opioid-prescribing guideline on clinician and patient outcomes and that the agency is committed to updating the recommendations when new evidence is available.
Officials at the Centers for Disease Control and Prevention are warning against the misapplication of the agency’s 2016 guidelines on opioid prescribing, as well as clarifying dosage recommendations for patients starting or stopping pain medications.
In a perspective published in the New England Journal of Medicine on April 24, lead author Deborah Dowell, MD, chief medical officer for the CDC’s National Center for Injury Prevention and Control, conveyed concern that some policies and practices derived from the 2016 CDC Guideline for Prescribing Opioids for Chronic Pain are inconsistent with the recommendations and often go beyond their scope.
Misapplication examples include inappropriately applying the guideline to patients in active cancer treatment, patients experiencing acute sickle cell crises, or patients experiencing postsurgical pain, Dr. Dowell wrote.
The guideline offers guidance to clinicians treating chronic pain in adults who are already receiving opioids long-term at high dosages, she noted. It includes advice on maximizing nonopioid treatment, reviewing risks associated with continuing high-dose opioids, and collaborating with patients who agree to taper dosage, among other guidance.
Any application of the guideline’s dosage recommendation that results in hard limits or “cutting off” opioids is also an incorrect use of the recommendations, according to Dr. Dowell.
While the guideline advises clinicians to start opioids at the lowest effective dosage and avoid increasing dosage to 90 morphine milligram equivalents per day or more, that statement does not suggest discontinuation of opioids already prescribed at high dosages, according to the CDC’s clarification.
The guidance also does not apply to patients receiving or starting medication-assisted treatment for opioid use disorder.

C3 inhibitor shows potential in PNH and AIHA
GLASGOW – APL-2, a complement factor 3 (C3) inhibitor, may be a future treatment option for paroxysmal nocturnal hemoglobinuria (PNH) and autoimmune hemolytic anemia (AIHA), according to investigators from two separate studies.
Early results from the phase 1b PADDOCK trial for PNH and the phase 2 PLAUDIT trial for AIHA showed that APL-2 significantly increased hemoglobin levels, with additional improvements reported in lactate dehydrogenase (LDH), absolute reticulocyte count, and bilirubin. The findings were presented at the annual meeting of the British Society for Haematology.
By blocking C3, APL-2 acts further upstream than approved C5 inhibitors eculizumab and ravulizumab, thereby controlling extravascular hemolysis in addition to intravascular hemolysis. This broader level of control is needed for some patients, the investigators said, such as those with PNH who have inadequate responses to C5 inhibition.
PNH
“Even in PNH patients treated with eculizumab, up to 70% may have suboptimal hemoglobin responses and about 30% may still require blood transfusions,” said lead author of the PADDOCK trial, Raymond Wong, MD, of the Prince of Wales Hospital in Hong Kong.
PNH patients included in the open-label, dose-escalation PADDOCK study had greater than 10% white blood cell clones, LDH that was at least twice the upper limit of normal, at least one transfusion within the past year, a platelet count below 30,000/mm3, and an absolute neutrophil count greater than 500 x 109/L.
Dr. Wong described experiences with a cohort of 20 patients who received 270 mg APL-2 subcutaneously daily for at least 28 days, with the option to continue treatment for up to 2 years thereafter, if desired.
From these 20 patients, 2 patients completed the initial 28-day period but did not elect to continue and 2 patients withdrew because of adverse events (ovarian cancer and severe aplastic anemia), leaving 16 patients in the present analysis. Before treatment, these individuals were transfusion dependent, with an average transfusion rate of 8.7 transfusions per year.
Results showed that mean hemoglobin increased from 8.0 g/dL at baseline to 10.8 g/dL at day 29 and 12.2 g/dL at day 85. LDH dropped 900%, from 2,416 U/L (9 times the upper limit of normal) to 271 U/L (0.9 times the upper limit of normal). Absolute reticulocyte count and bilirubin also normalized.
Overall, these improvements led to a meaningful clinical impact, Dr. Wong said, with fatigue scores improving and most patients becoming transfusion independent on maintenance therapy, with the exception of one patient who developed severe aplastic anemia after 1 year. No significant infections or thromboses occurred.
When asked where APL-2 might fit in with current treatment paradigm, Dr. Wong said that multiple applications for PNH are being investigated, including first-line therapy and after failure of eculizumab.
AIHA
Results from the phase 2 PLAUDIT trial, presented by Bruno Fattizzo, MD, of the University of Milan, offered a glimpse at APL-2 in a different setting: AIHA.
Eligibility required hemoglobin levels of less than 11 g/dL, signs of hemolysis, and positive direct antiglobulin test for IgG and/or complement C3.
Dr. Fattizzo discussed results from five patients with cold agglutinin disease and five patients with C3-positive warm AIHA who had received 56 days of therapy.
Among the five patients with cold agglutinin disease, mean hemoglobin increased from 8.7 g/dL to 12.1 g/dL, while patients with warm C3-positive AIHA had a mean increase from 9.3 g/dL to 11.3 g/dL. As with the PNH study, absolute reticulocyte count, LDH, and indirect bilirubin normalized across all 10 patients.
“Some of the patients included in the trial have already reached more than 48 weeks, something like 64 weeks in the study, and they are still doing well,” Dr. Fattizzo said. “So it really seems that those who are do respond really keep the response with ongoing treatment.”
Nine out of 12 patients with cold agglutinin disease (75%) and 8 out of 9 patients (89%) with warm AIHA experienced adverse events, although these were mostly grade 1 or 2 and deemed unrelated to APL-2 by the investigators.
Five grade 3 adverse events in six patients included oral squamous carcinoma, hemolytic flare, pneumonia, purpura, and acute kidney injury. Five grade 4 adverse events in two patients included high calcium, high creatinine, hypoxia, and hemolytic flare, causing these two patients to withdraw from the study. No grade 3 or 4 adverse events were considered related to APL-2.
“APL-2 appears to be well tolerated and safe,” Dr. Fattizzo said, adding that a phase 3 trial for cold agglutinin disease and C3-positive warm AIHA C3+ is planned.
Both studies are sponsored by Apellis Pharmaceuticals. Dr. Wong and his colleagues reported financial relationships with Alexion Pharmaceuticals, Apellis, Celgene, Janssen, and other companies. Dr. Fattizzo reported having no conflicts of interest.

REPORTING FROM BSH 2019
CDC clarifies opioid prescribing guidelines in cancer, sickle cell disease
Officials at the Centers for Disease Control and Prevention have clarified the agency’s guidelines on opioid prescribing after a trio of organizations raised concerns that insurers were inappropriately applying the recommendations to active cancer patients when making coverage determinations.
The CDC guidelines, released in March 2016, address when to initiate or continue opioids for chronic pain, opioid selection, dosage, duration, follow-up, and discontinuation, and assess risk and harms of opioid use. Although the guidelines clearly state they are intended for clinicians prescribing opioids outside of active cancer treatment, insurance companies are still applying the guidelines to opioid coverage decisions for patients with active cancer, according to a Feb. 13, 2019, letter sent to the CDC from leaders at the American Society of Clinical Oncology, the National Comprehensive Cancer Network, and the American Society of Hematology.
Additionally, the associations wrote that the CDC’s recommendations pose coverage problems for sickle cell patients and select groups of cancer survivors who may benefit from opioids for pain management. The groups asked the CDC to issue a clarification to ensure appropriate implementation of the opioid recommendations.
In a Feb. 28, 2019, letter to ASCO, NCCN, and ASH, Deborah Dowell, MD, chief medical officer for the CDC’s National Center for Injury Prevention and Control took note of the concerns, clarifying that the recommendations are not intended to deny clinically appropriate opioid therapy to any patients who suffer chronic pain, but rather to ensure that physicians and patients consider all safe and effective treatment options.
The CDC guidance may apply to cancer survivors in certain conditions, Dr. Dowell wrote, namely when survivors experience chronic pain after cancer treatment completion, are in clinical remission, and are under cancer surveillance only. However, she agreed that, for select groups of cancer survivors with persistent pain caused by past cancer, the ratio of opioid benefits to risks for chronic pain is unique. She referred health providers to guidelines by ASCO on chronic pain management for adult cancer survivors and NCCN guidance on managing adult cancer pain when considering opioids for pain control in such populations.
Special considerations in sickle cell disease may also change the balance of opioid risks to benefits for pain management, Dr. Dowell wrote, referring providers and insurers to additional guidance on sickle cell disease from the National Institute of Health when making treatment and reimbursement decisions.
“Clinical decision making should be based on the relationship between the clinician and patient, with an understanding of the patient’s clinical situation, functioning, and life context, as well as careful consideration of the benefits and risk of all treatment options, including opioid therapy,” Dr. Dowell wrote. “CDC encourages physicians to continue using their clinical judgment and base treatment on what they know about their patients, including the use of opioids if determined to be the best course of treatment.”
Clifford A. Hudis, MD, CEO of ASCO, praised the clarification, calling the letter necessary to clear up confusion and prevent inappropriate coverage decisions.
“This clarification from CDC is critically important because, while the agency’s guideline clearly states that it is not intended to apply to patients during active cancer and sickle cell disease treatment, many payers have been inappropriately using it to make opioid coverage determinations for those exact populations,” Dr. Hudis said in a statement.
Sickle cell patients suffer from severe, chronic pain, which is debilitating on its own without the added burden of having to constantly appeal coverage denials, added ASH President Roy Silverstein, MD.
“We appreciate CDC’s acknowledgment that the challenges of managing severe and chronic pain in conditions, such as sickle cell disease, require special consideration, and we hope payers will take the CDC’s clarification into account to ensure that patients’ pain management needs are covered,” he said in the same statement.
