Bulevirtide is a 47-amino acid peptide with a fatty acid, a myristoyl residue, at the N-terminus and an amidated C-terminus. The active substance is available as acetate salt. The counter ion acetate is bound in ionic form to basic groups of the peptide molecule and is present in a non-stoichiometric ratio. The chemical name of bulevirtide is (N-Myristoyl-glycyl-L-threonyl-L-asparaginyl-L-leucyl-L-seryl-L-valyl-Lprolyl-L-asparaginyl-L-prolyl-L-leucyl-glycyl-L-phenylalanyl-L-phenylalanyl-L-prolyl-L-aspartyl-L-histidyl-Lglutaminyl-L-leucyl-L-aspartyl-L-prolyl-L-alanyl-L-phenylalanyl-glycyl-L-alanyl-L-asparaginyl-L-seryl-Lasparaginyl-L-asparaginyl-Lprolyl-L-aspartyl-L-tryptophanyl-L-aspartyl-L-phenylalanyl-L-asparaginyl-L-prolylL-asparaginyl-L-lysyl-L-aspartyl-L-histidyl-L-tryptophanyl-L-prolyl-L-glutamyl-L-alanyl-L-asparaginyl-L-lysylL-valylglycinamide, acetate salt. It corresponds to the molecular formula C248H355N65O72, its relative molecular mass is 5398.9 g/mol
Bulevirtide appears as a white or off-white hygroscopic powder. It is practically insoluble in water and soluble at concentrations of 1 mg/ml in 50% acetic acid and about 7 mg/ml in carbonate buffer solution at pH 8.8, respectively. The structure of the active substance (AS) was elucidated by a combination of infrared spectroscopy (IR), mass spectrometry (MS), amino acid analysis and sequence analysis Other characteristics studied included ultraviolet (UV) spectrum, higher order structure (1D- and 2D- nuclear magnetic resonance spectroscopy (NMR)) and aggregation (Dynamic Light Scattering). Neither tertiary structure nor aggregation states of bulevirtide have been identified. With regard to enantiomeric purity, all amino acids are used in L-configuration except glycine, which is achiral by nature. Two batches of bulevirtide acetate were evaluated for enanatiomeric purity and no relevant change in configuration during synthesis was detected.
Bulevirtide is manufactured by a single manufacturer. It is a chemically synthesised linear peptide containing only naturally occurring amino acids. The manufacturing of this peptide is achieved using standard solidphase peptide synthesis (SPPS) on a 4-methylbenzhydrylamine resin (MBHA resin) derivatised with Rink amide linker in order to obtain a crude peptide mixture. This crude mixture is purified through a series of washing and preparative chromatography steps. Finally, the purified peptide is freeze-dried prior to final packaging and storage. The process involves further four main steps: synthesis of the protected peptide on the resin while side-chain functional groups are protected as applicable; cleavage of the peptide from the resin, together with the removal of the side chain protecting groups to obtain the crude peptide; purification; and lyophilisation. Two chromatographic systems are used for purification. No design space is claimed. Resin, Linker Fmoc protected amino acids and myristic acid are starting materials in line with ICH Q11. Sufficient information is provided on the source and the synthetic route of the starting materials. The active substance is obtained as a nonsterile, lyophilised powder. All critical steps and parameters were presented and clearly indicated in the description of the manufacturing process. The process description includes also sufficient information on the type of equipment for the SPPS, in-process controls (IPCs). The circumstances under which reprocessing might be performed were clearly presented. No holding times are proposed. Overall the process is sufficiently described.
The finished product is a white to off white lyophilised powder for solution for injection supplied in single-use vials. Each vial contains bulevirtide acetate equivalent to 2 mg bulevirtide. The composition of the finished product was presented. The powder is intended to be dissolved in 1 ml of water for injection per vial. After reconstitution the concentration of bulevirtide net peptide solution in the vial is 2 mg/ml. The components of the formulation were selected by literature review and knowledge of compositions of similar products available on the market at that time, containing HCl, water, mannitol, sodium carbonate, sodium hydrogen carbonate and sodium hydroxide. All excipients are normally used in the manufacture of lyophilisates. The quality of the excipients complies with their respective Ph. Eur monographs. The intrinsic properties of the active substance and the compounding formulation do not support microbiological growth as demonstrated by the stability data. No additional preservatives are therefore needed.
Hepcludex is an antiviral medicine used to treat chronic (long-term) hepatitis delta virus (HDV) infection in adults with compensated liver disease (when the liver is damaged but is still able to work), when the presence of viral RNA (genetic material) has been confirmed by blood tests.
HDV is an ‘incomplete’ virus, because it cannot replicate in cells without the help of another virus, the hepatitis B virus. Because of this, patients infected with the virus always also have hepatitis B.
Hepcludex contains the active substance bulevirtide.
The most common side effects include raised levels of bile salts in the blood and reactions at the site of injection.
Bulevirtide works by attaching to and blocking a receptor (target) through which the hepatitis delta and hepatitis B viruses enter liver cells. By blocking the entry of the virus into the cells, it limits the ability of HDV to replicate and its effects in the body, reducing symptoms of the disease.
Bulevirtide was approved for medical use in the European Union in July 2020.
Mechanism of action
The hepatitis B virus uses its surface lipopeptide pre-S1 for docking to mature liver cells via their sodium/bile acid cotransporter (NTCP) and subsequently entering the cells. Myrcludex B is a synthetic N-acylated pre-S1 that can also dock to NTCP, blocking the virus’s entry mechanism.
The drug is also effective against hepatitis D because the hepatitis D virus is only infective in the presence of a hepatitis B virus infection.

Tepezza (teprotumumab-trbw) is a fully human monoclonal antibody (mAb) and a targeted inhibitor of the insulin-like growth factor 1 receptor (IGF-1R) for the treatment of active thyroid eye disease (TED).
FDA Approves Tepezza (teprotumumab-trbw) for the Treatment of Thyroid Eye Disease (TED) – January 21, 2020
Today, the U.S. Food and Drug Administration (FDA) approved Tepezza (teprotumumab-trbw) for the treatment of adults with thyroid eye disease, a rare condition where the muscles and fatty tissues behind the eye become inflamed, causing the eyes to be pushed forward and bulge outwards (proptosis). Today’s approval represents the first drug approved for the treatment of thyroid eye disease.
“Today’s approval marks an important milestone for the treatment of thyroid eye disease. Currently, there are very limited treatment options for this potentially debilitating disease. This treatment has the potential to alter the course of the disease, potentially sparing patients from needing multiple invasive surgeries by providing an alternative, non surgical treatment option,” said Wiley Chambers, M.D., deputy director of the Division of Transplant and Ophthalmology Products in the FDA’s Center for Drug Evaluation and Research. “Additionally, thyroid eye disease is a rare disease that impacts a small percentage of the population, and for a variety of reasons, treatments for rare diseases are often unavailable. This approval represents important progress in the approval of effective treatments for rare diseases, such as thyroid eye disease.”
Thyroid eye disease is associated with the outward bulging of the eye that can cause a variety of symptoms such as eye pain, double vision, light sensitivity or difficulty closing the eye. This disease impacts a relatively small number of Americans, with more women than men affected. Although this condition impacts relatively few individuals, thyroid eye disease can be incapacitating. For example, the troubling ocular symptoms can lead to the progressive inability of people with thyroid eye disease to perform important daily activities, such as driving or working.
Tepezza was approved based on the results of two studies (Study 1 and 2) consisting of a total of 170 patients with active thyroid eye disease who were randomized to either receive Tepezza or a placebo. Of the patients who were administered Tepezza, 71% in Study 1 and 83% in Study 2 demonstrated a greater than 2 millimeter reduction in proptosis (eye protrusion) as compared to 20% and 10% of subjects who received placebo, respectively.
The most common adverse reactions observed in patients treated with Tepezza are muscle spasm, nausea, alopecia (hair loss), diarrhea, fatigue, hyperglycemia (high blood sugar), hearing loss, dry skin, dysgeusia (altered sense of taste) and headache. Tepezza should not be used if pregnant, and women of child-bearing potential should have their pregnancy status verified prior to beginning treatment and should be counseled on pregnancy prevention during treatment and for 6 months following the last dose of Tepezza.
The FDA granted this application Priority Review, in addition to Fast Track and Breakthrough Therapy Designation. Additionally, Tepezza received Orphan Drug designation, which provides incentives to assist and encourage the development of drugs for rare diseases or conditions. Development of this product was also in part supported by the FDA Orphan Products Grants Program, which provides grants for clinical studies on safety and efficacy of products for use in rare diseases or conditions.
The FDA granted the approval of Tepezza to Horizon Therapeutics Ireland DAC.
Teprotumumab (RG-1507), sold under the brand name Tepezza, is a medication used for the treatment of adults with thyroid eye disease, a rare condition where the muscles and fatty tissues behind the eye become inflamed, causing the eyes to be pushed forward and bulge outwards (proptosis).
The most common adverse reactions observed in people treated with teprotumumab-trbw are muscle spasm, nausea, alopecia (hair loss), diarrhea, fatigue, hyperglycemia (high blood sugar), hearing loss, dry skin, dysgeusia (altered sense of taste) and headache. Teprotumumab-trbw should not be used if pregnant, and women of child-bearing potential should have their pregnancy status verified prior to beginning treatment and should be counseled on pregnancy prevention during treatment and for six months following the last dose of teprotumumab-trbw.
Teprotumumab was first investigated for the treatment of solid and hematologic tumors, including breast cancer, Hodgkin’s and non-Hodgkin’s lymphoma, non-small cell lung cancer and sarcoma. Although results of phase I and early phase II trials showed promise, research for these indications were discontinued in 2009 by Roche. Phase II trials still in progress were allowed to complete, as the development was halted due to business prioritization rather than safety concerns.
Teprotumumab was subsequently licensed to River Vision Development Corporation in 2012 for research in the treatment of ophthalmic conditions. Horizon Pharma (now Horizon Therapeutics, from hereon Horizon) acquired RVDC in 2017, and will continue clinical trials. It is in phase III trials for Graves’ ophthalmopathy (also known as thyroid eye disease (TED)) and phase I for diabetic macular edema. It was granted Breakthrough Therapy, Orphan Drug Status and Fast Track designations by the FDA for Graves’ ophthalmopathy.
In a multicenter randomized trial in patients with active Graves’ ophthalmopathy Teprotumumab was more effective than placebo in reducing the clinical activity score and proptosis. In February 2019 Horizon announced results from a phase 3 confirmatory trial evaluating teprotumumab for the treatment of active thyroid eye disease (TED). The study met its primary endpoint, showing more patients treated with teprotumumab compared with placebo had a meaningful improvement in proptosis, or bulging of the eye: 82.9 percent of teprotumumab patients compared to 9.5 percent of placebo patients achieved the primary endpoint of a 2 mm or more reduction in proptosis (p<0.001). Proptosis is the main cause of morbidity in TED. All secondary endpoints were also met and the safety profile was consistent with the phase 2 study of teprotumumab in TED. On 10th of July 2019 Horizon submitted a Biologics License Application (BLA) to the FDA for teprotumumab for the Treatment of Active Thyroid Eye Disease (TED). Horizon requested priority review for the application – if so granted (FDA has a 60-day review period to decide) it would result in a max. 6 month review process.
Teprotumumab-trbw was approved for use in the United States in January 2020, for the treatment of adults with thyroid eye disease.
Teprotumumab-trbw was approved based on the results of two studies (Study 1 and 2) consisting of a total of 170 patients with active thyroid eye disease who were randomized to either receive teprotumumab-trbw or a placebo. Of the subjects who were administered Tepezza, 71% in Study 1 and 83% in Study 2 demonstrated a greater than two millimeter reduction in proptosis (eye protrusion) as compared to 20% and 10% of subjects who received placebo, respectively.
The U.S. Food and Drug Administration (FDA) granted the application for teprotumumab-trbw fast track designation, breakthrough therapy designation, priority review designation, and orphan drug designation. The FDA granted the approval of Tepezza to Horizon Therapeutics Ireland DAC.

PRIORITY; Orphan, NDA 212608
Avapritinib, sold under the brand name Ayvakit, is a medication used for the treatment of tumors due to one specific rare mutation: It is specifically intended for adults with unresectable or metastatic ( y) gastrointestinal stromal tumor (GIST) that harbor a platelet-derived growth factor receptor alpha (PDGFRA) exon 18 mutation.
Common side effects are edema (swelling), nausea, fatigue/asthenia (abnormal physical weakness or lack of energy), cognitive impairment, vomiting, decreased appetite, diarrhea, hair color changes, increased lacrimation (secretion of tears), abdominal pain, constipation, rash. and dizziness.
The U.S. Food and Drug Administration (FDA) approved avapritinib in January 2020. The application for avapritinib was granted fast track designation, breakthrough therapy designation, and orphan drug designation. The FDA granted approval of Ayvakit to Blueprint Medicines Corporation.
Avapritinib was approved based on the results from the Phase I NAVIGATOR clinical trial involving 43 patients with GIST harboring a PDGFRA exon 18 mutation, including 38 subjects with PDGFRA D842V mutation. Subjects received avapritinib 300 mg or 400 mg orally once daily until disease progression or they experienced unacceptable toxicity. The recommended dose was determined to be 300 mg once daily. The trial measured how many subjects experienced complete or partial shrinkage (by a certain amount) of their tumors during treatment (overall response rate). For subjects harboring a PDGFRA exon 18 mutation, the overall response rate was 84%, with 7% having a complete response and 77% having a partial response. For the subgroup of subjects with PDGFRA D842V mutations, the overall response rate was 89%, with 8% having a complete response and 82% having a partial response. While the median duration of response was not reached, 61% of the responding subjects with exon 18 mutations had a response lasting six months or longer (31% of subjects with an ongoing response were followed for less than six months).

Sickle cell disease is a lifelong, inherited blood disorder in which red blood cells are abnormally shaped (in a crescent, or “sickle” shape), which restricts the flow in blood vessels and limits oxygen delivery to the body’s tissues, leading to severe pain and organ damage. It is also characterized by severe and chronic inflammation that worsens vaso-occlusive crises during which patients experience episodes of extreme pain and organ damage. Nonclinical studies have demonstrated that Oxbryta inhibits red blood cell sickling, improves red blood cell deformability (ability of a red blood cell to change shape) and improves the blood’s ability to flow.
“Oxbryta is an inhibitor of deoxygenated sickle hemoglobin polymerization, which is the central abnormality in sickle cell disease,” said Richard Pazdur, M.D., director of the FDA’s Oncology Center of Excellence and acting director of the Office of Oncologic Diseases in the FDA’s Center for Drug Evaluation and Research. “With Oxbryta, sickle cells are less likely to bind together and form the sickle shape, which can cause low hemoglobin levels due to red blood cell destruction. This therapy provides a new treatment option for patients with this serious and life-threatening condition.”
Oxbryta’s approval was based on the results of a clinical trial with 274 patients with sickle cell disease. In the study, 90 patients received 1500 mg of Oxbryta, 92 patients received 900 mg of Oxbryta and 92 patients received a placebo. Effectiveness was based on an increase in hemoglobin response rate in patients who received 1500 mg of Oxbryta, which was 51.1% for these patients compared to 6.5% in the placebo group.

- Anavex Life Sciences is developing ANAVEX-2-73 and its active metabolite ANAVEX-19-144, for treating Alzheimer’s disease, epilepsy, stroke and Rett syndrome.
ANAVEX2-73 is an experimental drug is in Phase II trials for Alzheimer’s disease, phase I trials for epilepsy, and in preclinical trials for amyotrophic lateral sclerosis, Parkinson’s disease, Rett syndrome, stroke. ANAVEX2-73 acts as a muscarinic receptor and a moderate sigma1 receptor agonist. ANAVEX2-73 may function as a pro-drug for ANAVEX19-144 as well as a drug itself. ANAVEX19-144 is the active metabolite of ANAVEX 1-41, which is similar to ANAVEX2-73 but it is not as selective for sigma receptor.
Properties and uses
ANAVEX2-73 has an inhibitory constant (ki) lower than 500 nM for all M1–M4 muscarinic acetylcholine receptor subtypes, demonstrating that it acts as a powerful antimuscarinic compound. ANAVEX2-73 was originally tested in mice against the effect of the muscarinic receptor antagonist scopolamine, which induces learning impairment. M1 receptor agonists are known to reverse the amnesia caused by scopolamine. Scopolamine is used in the treatment of Parkinson’s disease and motion sickness by reducing the secretions of the stomach and intestines and can also decreases nerve signals to the stomach. This is via competitive inhibition of muscarinic receptors. Muscarinic receptors are involved in the formation of both short term and long term memories. Experiments in mice have found that M1 and M3 receptor agonists inhibit the formation of amyloid-beta and target GSK-3B.[clarification needed]Furthermore, stimulation of the M1 receptor activates AF267B, which in turn blocks β-secretase, which cleaves the amyloid precursor protein to produce the amyloid-beta peptide. These amyloid-beta peptides aggregate together to form plaques. This enzyme[clarification needed] is involved in the formation of Tau plaques, which are common in Alzheimer’s disease.[clarification needed]Therefore. M1 receptor activation appears to decreases tau hyperphosphorylation and amyloid-beta accumulation.
Sigma1 activation appears to be only involved in long-term memory processes. This partly explains why ANAVEX2-73 seems to be more effective in reversing scopolamine-induced long-term memory problems compared to short-term memory deficits. The sigma-1 receptor is located on mitochondria-associated endoplasmic reticulum membranes and modulates the ER stress response and local calcium exchanges with the mitochondria. ANAVEX2-73 prevented Aβ25-35-induced increases in lipid peroxidation levels, Bax/Bcl-2ratio and cytochrome c release into the cytosol, which are indicative of elevated toxicity.[clarification needed] ANAVEX2-73 inhibits mitochondrial respiratory dysfunction and therefore prevents against oxidative stress and apoptosis. This drug prevented the appearance of oxidative stress. ANAVEX2-73 also exhibits anti-apoptotic and anti-oxidant activity. This is due in part because sigma-1 agonists stimulate the anti-apoptoic factor Bcl-2 due to reactive oxygen species dependent transcriptional activation of nuclear factor kB. Results from Marice (2016) demonstrate that sigma1 compounds offer a protective potential, both alone and possibly with other agents like donepezil, an acetylcholinesterase inhibitor, or the memantine, a NMDA receptor antagonist.

FDA approves treatment Inrebic (fedratinib) for patients with rare bone marrow disorder
Today, the U.S. Food and Drug Administration approved Inrebic (fedratinib) capsules to treat adult patients with certain types of myelofibrosis.
“Prior to today, there was one FDA-approved drug to treat patients with myelofibrosis, a rare bone marrow disorder. Our approval today provides another option for patients,” said Richard Pazdur, M.D., director of the FDA’s Oncology Center of Excellence and acting director of the Office of Hematology and Oncology Products in the FDA’s Center for Drug Evaluation and Research. “The FDA is committed to encouraging the development of treatments for patients with rare diseases and providing alternative options, as not all patients respond in the same way.”
Myelofibrosis is a chronic disorder where scar tissue forms in the bone marrow and the production of the blood cells moves from the bone marrow to the spleen and liver, causing organ enlargement. It can cause extreme fatigue, shortness of breath, pain below the ribs, fever, night sweats, itching and bone pain. When myelofibrosis occurs on its own, it is called primary myelofibrosis. Secondary myelofibrosis occurs when there is excessive red blood cell production (polycythemia vera) or excessive platelet production (essential thrombocythemia) that evolves into myelofibrosis.
Jakafi (ruxolitinib) was approved by the FDA in 2011. The approval of Inrebic for intermediate-2 or high-risk primary or secondary (post-polycythemia vera or post-essential thrombocythemia) myelofibrosis was based on the results of a clinical trial where 289 patients with myelofibrosis were randomized to receive two different doses (400 mg or 500 mg daily by mouth) of fedratinib or placebo. The clinical trial showed that 35 of 96 patients treated with the fedratinib 400 mg daily dose (the dose recommended in the approved label) experienced a significant therapeutic effect (measured by greater than or equal to a 35% reduction from baseline in spleen volume at the end of cycle 6 (week 24) as measured by an MRI or CT scan with a follow-up scan four weeks later). As a result of treatment with Inrebic, 36 patients experienced greater than or equal to a 50% reduction in myelofibrosis-related symptoms, such as night sweats, itching, abdominal discomfort, feeling full sooner than normal, pain under ribs on left side, and bone or muscle pain.
The prescribing information for Inrebic includes a Boxed Warning to advise health care professionals and patients about the risk of serious and fatal encephalopathy (brain damage or malfunction), including Wernicke’s, which is a neurologic emergency related to a deficiency in thiamine. Health care professionals are advised to assess thiamine levels in all patients prior to starting Inrebic, during treatment and as clinically indicated. If encephalopathy is suspected, Inrebic should be immediately discontinued.
Common side effects for patients taking Inrebic are diarrhea, nausea, vomiting, fatigue and muscle spasms. Health care professionals are cautioned that patients may experience severe anemia (low iron levels) and thrombocytopenia (low level of platelets in the blood). Patients should be monitored for gastrointestinal toxicity and for hepatic toxicity (liver damage). The dose should be reduced or stopped if a patient develops severe diarrhea, nausea or vomiting. Treatment with anti-diarrhea medications may be recommended. Patients may develop high levels of amylase and lipase in their blood and should be managed by dose reduction or stopping the mediation. Inrebic must be dispensed with a patient Medication Guide that describes important information about the drug’s uses and risks.
The FDA granted this application Priority Review designation. Inrebic also received Orphan Drug designation, which provides incentives to assist and encourage the development of drugs for rare diseases. The FDA granted the approval of Inrebic to Impact Biomedicines, Inc., a wholly-owned subsidiary of Celgene Corporation.
FDA approves third oncology drug Rozlytrek (entrectinib) that targets a key genetic driver of cancer, rather than a specific type of tumor
FDA also approves drug for second indication in a type of lung cancer
The U.S. Food and Drug Administration today granted accelerated approval to Rozlytrek (entrectinib), a treatment for adult and adolescent patients whose cancers have the specific genetic defect, NTRK (neurotrophic tyrosine receptor kinase) gene fusion and for whom there are no effective treatments.
“We are in an exciting era of innovation in cancer treatment as we continue to see development in tissue agnostic therapies, which have the potential to transform cancer treatment. We’re seeing continued advances in the use of biomarkers to guide drug development and the more targeted delivery of medicine,” said FDA Acting Commissioner Ned Sharpless, M.D. “Using the FDA’s expedited review pathways, including breakthrough therapy designation and accelerated approval process, we’re supporting this innovation in precision oncology drug development and the evolution of more targeted and effective treatments for cancer patients. We remain committed to encouraging the advancement of more targeted innovations in oncology treatment and across disease types based on our growing understanding of the underlying biology of diseases.”
This is the third time the agency has approved a cancer treatment based on a common biomarker across different types of tumors rather than the location in the body where the tumor originated. The approval marks a new paradigm in the development of cancer drugs that are “tissue agnostic.” It follows the policies that the FDA developed in a guidance document released in 2018. The previous tissue agnostic indications approved by the FDA were pembrolizumab for tumors with microsatellite instability-high (MSI-H) or mismatch repair deficient (dMMR) tumors in 2017 and larotrectinib for NTRK gene fusion tumors in 2018.
“Today’s approval includes an indication for pediatric patients, 12 years of age and older, who have NTRK-fusion-positive tumors by relying on efficacy information obtained primarily in adults. The FDA continues to encourage the inclusion of adolescents in clinical trials. Traditionally, clinical development of new cancer drugs in pediatric populations is not started until development is well underway in adults, and often not until after approval of an adult indication,” said Richard Pazdur, M.D., director of the FDA’s Oncology Center of Excellence and acting director of the Office of Hematology and Oncology Products in the FDA’s Center for Drug Evaluation and Research. “Efficacy in adolescents was derived from adult data and safety was demonstrated in 30 pediatric patients.”
The ability of Rozlytrek to shrink tumors was evaluated in four clinical trials studying 54 adults with NTRK fusion-positive tumors. The proportion of patients with substantial tumor shrinkage (overall response rate) was 57%, with 7.4% of patients having complete disappearance of the tumor. Among the 31 patients with tumor shrinkage, 61% had tumor shrinkage persist for nine months or longer. The most common cancer locations were the lung, salivary gland, breast, thyroid and colon/rectum.
Rozlytrek was also approved today for the treatment of adults with non-small cell lung cancer whose tumors are ROS1-positive (mutation of the ROS1 gene) and has spread to other parts of the body (metastatic). Clinical studies evaluated 51 adults with ROS1-positive lung cancer. The overall response rate was 78%, with 5.9% of patients having complete disappearance of their cancer. Among the 40 patients with tumor shrinkage, 55% had tumor shrinkage persist for 12 months or longer.
Rozlytrek’s common side effects are fatigue, constipation, dysgeusia (distorted sense of taste), edema (swelling), dizziness, diarrhea, nausea, dysesthesia (distorted sense of touch), dyspnea (shortness of breath), myalgia (painful or aching muscles), cognitive impairment (confusion, problems with memory or attention, difficulty speaking, or hallucinations), weight gain, cough, vomiting, fever, arthralgia and vision disorders (blurred vision, sensitivity to light, double vision, worsening of vision, cataracts, or floaters). The most serious side effects of Rozlytrek are congestive heart failure (weakening or damage to the heart muscle), central nervous system effects (cognitive impairment, anxiety, depression including suicidal thinking, dizziness or loss of balance, and change in sleep pattern, including insomnia and excessive sleepiness), skeletal fractures, hepatotoxicity (damage to the liver), hyperuricemia (elevated uric acid), QT prolongation (abnormal heart rhythm) and vision disorders. Health care professionals should inform females of reproductive age and males with a female partner of reproductive potential to use effective contraception during treatment with Rozlytrek. Women who are pregnant or breastfeeding should not take Rozlytrek because it may cause harm to a developing fetus or newborn baby.
Rozlytrek was granted accelerated approval. This approval commits the sponsor to provide additional data to the FDA. Rozlytrek also received Priority Review, Breakthrough Therapy and Orphan Drug designation. The approval of Rozlytrek was granted to Genentech, Inc.
