Seventy-five percent of
BESREMi
patients experienced reduction in severe PV symptoms Medical chart review supports importance of symptomatic burden in real-world treatment of PV and clinical utility of cytoreductive therapies compared to phlebotomy alone BURLINGTON, Mass.--(BUSINESS WIRE)-- PharmaEssentia USA Corporation, a subsidiary of PharmaEssentia Corporation (TWSE: 6446), a global biopharmaceutical innovator based in Taiwan leveraging deep expertise and proven scientific principles to deliver new biologics in hematology and oncology, announced today results from a real-world data review published in the Journal of Clinical Oncology supplement (abstract # e18530) for the 2024 American Society of Clinical Oncology (ASCO) Annual Meeting Proceedings. The retrospective medical chart review demonstrates the potential for cytoreductive therapies (CTs) to impact the burden of illness of
polycythemia vera (PV)
in patients, with
ropeginterferon alfa-2B
(marketed as
BESREMi
®) showing the greatest percentage reduction (when compared to other CTs) in patients seen with severe PV symptoms. This review included patients receiving phlebotomy alone (n=103) and each of the following cytoreductive therapies with or without concomitant phlebotomy:
hydroxyurea
(n=165),
ruxolitinib
(n=115),
peginterferon
alfa-2a (n=44) and
ropeginterferon
alfa-2b (n=45). From their initial presentation to their most recent visit, healthcare providers observed a reduction in the number of patients with severe symptoms across all
CTs
, with the greatest reduction in severe symptoms seen in
ropeginterferon
alfa-2b patients, with a reduction from 12 to 3 patients reporting severe symptoms (75%). They observed a reduction for
hydroxyurea
from 7 to 4 patients (43%); in
ruxolitinib
from11 to 6 patients (45%), and in peginterferon alfa-2a from12 to 8 patients (33%). Among patients treated with phlebotomy alone, the top reasons physicians indicated they would initiate cytoreductive therapy would be worsening of symptoms (32%), increased frequency of phlebotomy (29%) or difficulty to control hematocrit (24%). “PV is a chronic and life-threatening
myeloproliferative neoplasm
associated with significant clinical, economic and patient burden,” said Adan Sosa, Pharm.D., Director of Health Economics and Outcomes Research at PharmaEssentia. “When phlebotomy fails, the top reason healthcare providers indicated they would initiate cytoreductive therapy for PV patients is worsening of symptoms – an insight that supports the importance of symptomatic burden in PV treatment, beyond hematologic response. As healthcare providers work towards best practice PV care, this review supports the importance of
BESREMi
as a therapeutic option that demonstrates clinical efficacy and may impact the symptomatic burden of illness for patients.” In 2023, the National Comprehensive
Cancer
Network Clinical Practice Guidelines in Oncology (NCCN Guidelines®) were updated to include
BESREMi
as the only preferred therapeutic option for the treatment of adults with both high- and low-risk
polycythemia vera
, regardless of treatment history. In this review, 63% of patients were identified as high risk (>60 y/o with history of
thrombosis
). “
Polycythemia vera
is a
chronic blood disorder
which is now recognized as a type of
cancer
. Physicians have focused on the patient’s blood counts and molecular results to make treatment decisions, and these real-world data reinforce that, for patients, symptoms matter,” said Robert B. Geller, M.D., Head of Medical at PharmaEssentia USA. “We hope these results provide additional evidence regarding the meaningful clinical value of
BESREMi
for patients with this
myeloproliferative neoplasm
, as well as encourage treating physicians to consider early and optimal cytoreductive interventions for appropriate PV patients.” More About this Review This medical chart review took place from October to December 2023 and included a total of 420 unique charts of U.S. adult patients with a confirmed diagnosis of PV in the prior 12 months, from 125 healthcare providers representing academic, community and private practice settings. Data were collected at three points in time, initial presentation of PV, diagnosis and at the most recent HCP visit; additionally, healthcare professional rationale on treatment decision-making was captured. About
Polycythemia Vera (PV)
Polycythemia vera (PV)
is a
cancer
originating from a disease-initiating stem cell in the bone marrow resulting in a chronic increase of red blood cells, white blood cells, and platelets. PV may result in cardiovascular complications such as
thrombosis
and
embolism
, and often transforms to
secondary myelofibrosis
or
leukemia
. While the molecular mechanism underlying PV is still subject of intense research, current results point to a set of acquired mutations, the most important being a mutant form of JAK2.1 About

: Elevated triglycerides may result in
pancreatitis
. Monitor serum triglycerides before
BESREMi
treatment and intermittently during therapy and manage when elevated. Consider discontinuation of
BESREMi
in patients with persistently, markedly elevated triglycerides. Hepatotoxicity: These toxicities may include increases in serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), gamma-glutamyl transferase (GGT) and bilirubin. Liver enzyme elevations have also been reported in patients after long-term
BESREMi
therapy. Monitor liver enzymes and hepatic function at baseline and during
BESREMi
treatment. Discontinue
BESREMi

jaundice
,
ascites
,
hepatic encephalopathy
,
hepatorenal syndrome
or
variceal hemorrhage
) during treatment. Renal Toxicity: Monitor serum creatinine at baseline and during therapy. Avoid use of
BESREMi
in patients with eGFR <30 mL/min. Discontinue
BESREMi
if severe
renal impairment
develops during treatment. Dental and Periodontal Toxicity: These toxicities may include
dental and periodontal disorders
, which may lead to loss of teeth. In addition, dry mouth could have a damaging effect on teeth and mucous membranes of the mouth during long-term treatment with

BESREMi
affects their abilities. Patients who experience
dizziness
,
somnolence
or
hallucination
during BESREMi therapy should avoid driving or using machinery. Embryo-Fetal Toxicity: Based on the mechanism of action,
BESREMi
can cause fetal harm when administered to a pregnant woman. Pregnancy testing is recommended in females of reproductive potential prior to treatment with
BESREMi
. Advise females of reproductive potential to use an effective method of contraception during treatment with
BESREMi
and for at least 8 weeks after the final dose. ADVERSE REACTIONS The most common adverse reactions reported in > 40% of patients in the PEGINVERA study (n=51) were
influenza-like illness
,
arthralgia
,
fatigue
,
pruritis
,
nasopharyngitis
, and
musculoskeletal pain
. In the pooled safety population (n=178), the most common adverse reactions greater than 10%, were liver enzyme elevations (20%),
leukopenia
(20%),
thrombocytopenia
(19%),
arthralgia
(13%),
fatigue
(12%),
myalgia
(11%), and
influenza-like illness
(11%). DRUG INTERACTIONS Patients on
BESREMi
who are receiving concomitant drugs which are CYP450 substrates with a narrow therapeutic index should be monitored to inform the need for dosage modification for these concomitant drugs. Avoid use with myelosuppressive agents and monitor patients receiving the combination for effects of excessive
myelosuppression
. Avoid use with narcotics, hypnotics or sedatives and monitor patients receiving the combination for effects of excessive CNS toxicity. USE IN SPECIFIC POPULATIONS Pregnancy: Based on mechanism of action and the role of
interferon alfa
in pregnancy and fetal development,
BESREMi
may cause fetal harm and should be assumed to have abortifacient potential when administered to a pregnant woman. There are adverse effects on maternal and fetal outcomes associated with
polycythemia vera
in pregnancy. Advise pregnant women of the potential risk to a fetus. Lactation: There are no data on the presence of
BESREMi
in human or animal milk, the effects on the breastfed child, or the effects on milk production. Because of the potential for serious adverse reactions in breastfed children from BESREMi, advise women not to breastfeed during treatment and for 8 weeks after the final dose. Females of Reproductive Potential:
BESREMi
may cause embryo-fetal harm when administered to a pregnant woman. Pregnancy testing prior to
BESREMi
treatment is recommended for females of reproductive potential. Advise female patients of reproductive potential to use effective contraception during treatment with
BESREMi
and for at least 8 weeks after the final dose. Pediatric Use: Safety and effectiveness in pediatric patients have not been established. Geriatric Use: In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function and of concomitant disease or other therapy.
