Mavorixafor, sold under the brand name Xolremdi, is a medication used for the treatment of WHIM syndrome. [1] It is a CXC chemokine receptor 4 antagonist. [1] It is taken by mouth. [1] It was developed by X4 Pharmaceuticals.
The most frequently reported adverse reactions include thrombocytopenia (low platelet counts), rash, rhinitis (stuffy nose), epistaxis (nosebleed), vomiting, and dizziness. [2]
Mavorixafor was approved for medical use in the United States in April 2024. [1] [2] [3] [4]
Mavorixafor is indicated in people twelve years of age and older with WHIM syndrome (warts, hypogammaglobulinemia, infections and myelokathexis) to increase the number of circulating mature neutrophils and lymphocytes. [1] [2]
Mavorixafor is expected to cause harm to the baby. [1] [2]
The effectiveness of mavorixafor was evaluated in a 52-week, randomized, double-blind, placebo-controlled trial that enrolled 31 adolescents and adults with WHIM syndrome (NCT03995108). [2] Mavorixafor improved absolute neutrophil counts and absolute lymphocyte counts, assessed over a 24-hour period four times throughout the study. [2] Absolute neutrophil counts below 500 cells/μL and absolute lymphocyte counts below 1000 cells/μL are associated with an increased risk of infections. [2] The average length of time over 24 hours that counts were above these levels was significantly longer with mavorixafor compared to the placebo group (15.0 hours compared to 2.8 hours for absolute neutrophil counts; 15.8 hours compared to 4.6 hours for absolute lymphocyte counts). [2]
Mavorixafor is the international nonproprietary name. [5]
Mavorixafor is in clinical trials for melanoma [6] and renal cell carcinoma. [7]
This is a list of AIDS-related topics, many of which were originally taken from the public domain U.S. Department of Health Glossary of HIV/AIDS-Related Terms, 4th Edition.
Myelokathexis is a congenital disorder of the white blood cells that causes severe, chronic leukopenia and neutropenia. The disorder is believed to be inherited in an autosomal dominant manner. Myelokathexis refers to retention (kathexis) of neutrophils in the bone marrow (myelo). The disorder shows prominent neutrophil morphologic abnormalities.
C-X-C chemokine receptor type 4 (CXCR-4) also known as fusin or CD184 is a protein that in humans is encoded by the CXCR4 gene. The protein is a CXC chemokine receptor.
Hypogammaglobulinemia is an immune system disorder in which not enough gamma globulins are produced in the blood. This results in a lower antibody count, which impairs the immune system, increasing risk of infection. Hypogammaglobulinemia may result from a variety of primary genetic immune system defects, such as common variable immunodeficiency, or it may be caused by secondary effects such as medication, blood cancer, or poor nutrition, or loss of gamma globulins in urine, as in nonselective glomerular proteinuria. Patients with hypogammaglobulinemia have reduced immune function; important considerations include avoiding use of live vaccines, and take precautionary measures when traveling to regions with endemic disease or poor sanitation such as receiving immunizations, taking antibiotics abroad, drinking only safe or boiled water, arranging appropriate medical cover in advance of travel, and ensuring continuation of any immunoglobulin infusions needed.
Ipilimumab, sold under the brand name Yervoy, is a monoclonal antibody medication that works to activate the immune system by targeting CTLA-4, a protein receptor that downregulates the immune system.
WHIM syndrome is a rare congenital immunodeficiency disorder characterized by chronic noncyclic neutropenia.
Nivolumab, sold under the brand name Opdivo, is an anti-cancer medication used to treat a number of types of cancer. This includes melanoma, lung cancer, malignant pleural mesothelioma, renal cell carcinoma, Hodgkin lymphoma, head and neck cancer, urothelial carcinoma, colon cancer, esophageal squamous cell carcinoma, liver cancer, gastric cancer, and esophageal or gastroesophageal junction cancer. It is administered intravenously.
Pembrolizumab, sold under the brand name Keytruda, is a humanized antibody used in cancer immunotherapy that treats melanoma, lung cancer, head and neck cancer, Hodgkin lymphoma, stomach cancer, cervical cancer, and certain types of breast cancer. It is administered by slow intravenous injection.
A CXCR4 antagonist is a substance which blocks the CXCR4 receptor and prevent its activation. Blocking the receptor stops the receptor's ligand, CXCL12, from binding which prevents downstream effects. CXCR4 antagonists are especially important for hindering cancer progression because one of the downstream effects initiated by CXCR4 receptor activation is cell movement which helps the spread of cancer, known as metastasis. The CXCR4 receptor has been targeted by antagonistic substances since being identified as a co-receptor in HIV and assisting the development of cancer. Macrocyclic ligands have been utilised as CXCR4 antagonists.
Inebilizumab, sold under the brand name Uplizna, is a medication for the treatment of neuromyelitis optica spectrum disorder (NMOSD) in adults. Inebilizumab is a humanized mAb that binds to and depletes CD19+ B cells including plasmablasts and plasma cells.
Relatlimab is a monoclonal antibody designed for the treatment of melanoma. It is used in combination with nivolumab to treat melanoma.
Ripretinib, sold under the brand name Qinlock, is a medication for the treatment of adults with advanced gastrointestinal stromal tumor (GIST), a type of tumor that originates in the gastrointestinal tract. It is taken by mouth. Ripretinib inhibits the activity of the kinases KIT and PDGFRA, which helps keep cancer cells from growing.
Idecabtagene vicleucel, sold under the brand name Abecma, is a cell-based gene therapy to treat multiple myeloma.
Avacopan, sold under the brand name Tavneos, is a medication used to treat anti-neutrophil cytoplasmic autoantibody-associated vasculitis. Avacopan is a complement 5a receptor antagonist and a cytochrome P450 3A4 inhibitor.
Ciltacabtagene autoleucel, sold under the brand name Carvykti, is an anti-cancer medication used to treat multiple myeloma. Ciltacabtagene autoleucel is a BCMA -directed genetically modified autologous chimeric antigen receptor (CAR) T-cell therapy. Each dose is customized using the recipient's own T-cells, which are collected and genetically modified, and infused back into the recipient.
Mosunetuzumab, sold under the brand name Lunsumio, is a monoclonal antibody used for the treatment of follicular lymphoma. It bispecifically binds CD20 and CD3 to engage T-cells. It was developed by Genentech.
Teclistamab, sold under the brand name Tecvayli, is a human bispecific monoclonal antibody used for the treatment of relapsed and refractory multiple myeloma. It is a bispecific antibody that targets the CD3 receptor expressed on the surface of T-cells and B-cell maturation antigen (BCMA), which is expressed on the surface of malignant multiple myeloma B-lineage cells.
Leniolisib (INN), sold under the brand name Joenja, is a medication used for the treatment of activated phosphoinositide 3-kinase delta syndrome (APDS). It is a kinase inhibitor that is taken by mouth.
