Vincristine, also known as leurocristine and marketed under the brand name Oncovin among others, is a chemotherapy medication used to treat a number of types of cancer. [5] This includes acute lymphocytic leukemia, acute myeloid leukemia, Hodgkin's disease, neuroblastoma, and small cell lung cancer among others. [5] It is given intravenously. [5]

Contents

Most people experience some side effects from vincristine treatment. [5] Commonly it causes a change in sensation, hair loss, constipation, difficulty walking, and headaches. [5] Serious side effects may include neuropathic pain, lung damage, or low white blood cells which increases the risk of infection. [5] Use during pregnancy may result in birth defects. [5] It works by stopping cells from dividing properly. [5] It is vital that it not be given intrathecally, as this may kill. [6]

Vincristine was first isolated in 1961. [7] It is on the World Health Organization's List of Essential Medicines. [8] [9] It is a vinca alkaloid that can be obtained from the Madagascar periwinkle Catharanthus roseus . [7]

Medical uses

Vincristine is delivered via intravenous infusion for use in various types of chemotherapy regimens. [3] Its main uses are in non-Hodgkin's lymphoma as part of the chemotherapy regimen CHOP R-CVP, Hodgkin's lymphoma as part of MOPP, COPP, BEACOPP, or the less popular Stanford V chemotherapy regimen in acute lymphoblastic leukemia (ALL), and in treatment for nephroblastoma as well as the chemotherapy regimen VDC-IE for Ewing's Sarcoma. [3] It is also used to induce remission in ALL with dexamethasone and L-asparaginase, and in combination with prednisone to treat childhood leukemia. [3] Vincristine is occasionally used as an immunosuppressant, for example, in treating thrombotic thrombocytopenic purpura (TTP) or chronic idiopathic thrombocytopenic purpura (ITP). [3]

Side effects

The main side effects of vincristine are chemotherapy-induced peripheral neuropathy, hyponatremia, constipation, and hair loss.

Vincristine-induced neuropathy is the main dose-limiting side effect. [10] Chemotherapy-induced peripheral neuropathy can be severe, and may be a reason to reduce or avoid using vincristine. The symptoms are progressive and enduring tingling numbness, pain and hypersensitivity to cold, beginning in the hands and feet and sometimes affecting the arms and legs. [11] One of the first symptoms of peripheral neuropathy is foot drop: A person with a family history of foot drop and/or Charcot-Marie-Tooth disease (CMT) should avoid vincristine. [12] A 2021 study has suggested that anakinra can reduce the neuropathy. [13] [14]

Accidental injection of vinca alkaloids into the spinal canal (intrathecal administration) is highly dangerous, with a mortality rate approaching 100 percent. The medical literature documents cases of ascending paralysis due to massive encephalopathy and spinal nerve demyelination, accompanied by intractable pain, almost uniformly leading to death. Several patients have survived after aggressive and immediate intervention. Rescue treatments consist of washout of the cerebrospinal fluid and administration of protective medications. [15] Children may do better following this injury. One child, who was aggressively treated at the time of the injection, recovered almost completely with only mild neurological deficits. [16] A significant series of inadvertent intrathecal vincristine administration occurred in China in 2007 when batches of cytarabine and methotrexate (both often used intrathecally) manufactured by the company Shanghai Hualian were found to be contaminated with vincristine. [17]

The overuse of vincristine may also lead to drug resistance by overexpression of the p-glycoprotein pump (Pgp). There is an attempt to overcome resistance by the addition of derivatives and substituents to the vincristine molecule. [18]

Mechanism of action

Vincristine works partly by binding to the tubulin protein, stopping the tubulin dimers from polymerizing to form microtubules, causing the cell to be unable to separate its chromosomes during the metaphase. [19] The cell then undergoes apoptosis. [20] The vincristine molecule inhibits leukocyte production and maturation. [21] A downside, however, to vincristine is that it does not only affect the division of cancer cells. It affects all rapidly dividing cell types, making it necessary for the very specific administration of the drug. [22]

Chemistry

The natural extraction of vincristine from Catharanthus roseus is produced at a percent yield of less than 0.0003%. For this reason, alternate methods to produce synthetic vincristine are being used. [23] Vincristine is created through the semi-synthesis coupling of indole alkaloids vindoline and catharanthine in the vinca plant. [24] It can also now be synthesized through a stereocontrolled total synthesis technique which retains the correct stereochemistry at C18' and C2'. The absolute stereochemistry at these carbons is responsible for vincristine's anticancer activity. [23]

The liposome encapsulation of vincristine enhances the efficacy of the vincristine drug while simultaneously decreasing the neurotoxicity associated with it. Liposome encapsulation increases vincristine's plasma concentration and circulation lifetime in the body, and allows the drug to enter cells more easily. [25]

History

Having been used as a folk remedy for centuries, studies in the 1950s revealed that the rosy periwinkle Catharanthus roseus contained over 120 alkaloids, many of which are biologically active, the two most significant being vincristine and vinblastine. Its use as an anti-tumor, anti-mutagenic agent is well documented in the ancient Ayurveda system of medicine and in the folk culture of Madagascar and Southern Africa. [26] It was not found to be anti-diabetic in double blinded controlled studies. [27] While initial studies for its use in diabetes mellitus were disappointing, the discovery that it caused myelosuppression (decreased activity of the bone marrow) led to its study in mice with leukemia, whose lifespan was prolonged by the use of a vinca preparation. Treatment of the ground plant with Skellysolve-B (hexane), followed by dilute tartaric acid and benzene extraction, provided an active fraction. This fraction was further chromatographed on deactivated aluminium oxide using trichloromethane and benzene, and separation by pH using extraction with various buffers to yield vincristine. [28]

Vincristine was approved by the US Food and Drug Administration (FDA) in July 1963 under the trade name Oncovin and was marketed by Eli Lilly and Company. The drug was initially developed by a team at Lilly Research Laboratories in Indianapolis where it was demonstrated that vincristine cured artificially induced leukemia in mice and remission of acute leukemias of childhood. [29]

Production of vincristine required one ton of dried periwinkle leaves to produce one ounce of vincristine. The periwinkle was grown on a ranch in Texas. [30]

Society and culture

Suppliers

Until recently, two generic drug makers were suppliers of vincristine in the United States: Teva and Pfizer. In 2019 Teva stopped producing vincristine, leaving Pfizer as the only company in production.[ citation needed ] Teva has said that they will restart production, and expect it to be available in 2020. [31]

Shortage

In October 2019 an impending shortage was reported; no adequate substitute is known for treating childhood-cancers. [32] By 2022, the shortage of vincristine continued. [33]

Controversy

Pharmaceutical bioprospecting

Vincristine's origins are debated as an example of pharmaceutical bioprospecting in the fields of ethnobotany and ethnomedicine. Some consider the Catharanthus roseus plant from which vincristine is derived, and its folk remedies to be endemic to Madagascar, and that Madagascar was denied royalties from vincristine sales. [34] However, Catharanthus roseus has a documented history in folk medicine treatments in other locations. In 1963, Lilly researchers acknowledged that the plant was used in Brazil to treat hemorrhage, scurvy, toothaches, and chronic wounds; in the British West Indies to treat diabetic ulcers; and in the Philippines and South Africa as an oral hypoglycemic agent – but not as a treatment for cancer. [35]

Catharanthus roseus has been a cosmopolitan species since before the Industrial Revolution and the plant's use in folk remedies suggested general bioactivity for diabetes treatment, not cancer. In the mid-eighteenth century, botanist Judith Sumner recorded the arrival of Catharanthus roseus at London's Chelsea Physic Garden from the Jardin des plantes in Paris. It's unclear how the plant first arrived in Paris and the details of its origins in Madagascar beyond reports of its transport from Madagascar by early European explorers. Vincristine was initially distributed at cost to increase accessibility, though later switched to a for-profit model to recover the costs of production and development. According to Michael Brown, vincristine may not be a tidy example of pharmaceutical bioprospecting, but it demonstrates how pharmaceuticals with a history of use in folk medicine have intellectual property claims which are difficult to untangle. [36]

Vincristine and confusion with other drugs in administration

Vincristine has been involved in a number of medical errors. Multiple instances of vincristine having been administered improperly, after having been confused with other drugs, have occurred. If delivered into the spine (intrathecal) it causes paralysis and usually death.

In 2003 two Australian oncology pharmacists recommended a solution. The suggested procedure is to prepare and administer vincristine in a small volume mini-bag rather than a syringe thus physically preventing the vincristine syringe being accidentally attached to a spinal needle. Acceptance of this safer procedure has been slow. [37]

Research

In 2012, the FDA approved a liposomal formulation of vincristine branded as Marqibo. [38] [39] [40] Marqibo was voluntarily withdrawn from the US market in November, 2021. [41]

A nano-particle bound version of vincristine was under development as of 2014. [42]

In 1995 and 2006 Malagasy agronomists and American political ecologists studied the production of Catharanthus roseus around Fort Dauphin and Ambovombe and its export as a natural source of the alkaloids used to make vincristine, vinblastine and other vinca alkaloid cancer drugs. Their research focused on the wild collection of periwinkle roots and leaves from roadsides and fields and its industrial cultivation on large farms. [43] [44] [45]

Chemotherapy is the type of cancer treatment that uses one or more anti-cancer drugs in a standard regimen. Chemotherapy may be given with a curative intent, or it may aim only to prolong life or to reduce symptoms. Chemotherapy is one of the major categories of the medical discipline specifically devoted to pharmacotherapy for cancer, which is called medical oncology.

<i>Catharanthus</i> Genus of flowering plants

Catharanthus is a genus of flowering plants in the family Apocynaceae. Like the genus Vinca, they are known commonly as periwinkles. There are eight known species. Seven are endemic to Madagascar, though one, C. roseus, is widely naturalized around the world. The eighth species, C. pusillus, is native to India and Sri Lanka. The name Catharanthus comes from the Greek for "pure flower".

<span class="mw-page-title-main">Intrathecal administration</span> Drug injected into the spinal canal

Intrathecal administration is a route of administration for drugs via an injection into the spinal canal, or into the subarachnoid space so that it reaches the cerebrospinal fluid (CSF). It is useful in several applications, such as for spinal anesthesia, chemotherapy, or pain management. This route is also used to introduce drugs that fight certain infections, particularly post-neurosurgical. Typically, the drug is given this way to avoid being stopped by the blood–brain barrier, as it may not be able to pass into the brain when given orally. Drugs given by the intrathecal route often have to be compounded specially by a pharmacist or technician because they cannot contain any preservative or other potentially harmful inactive ingredients that are sometimes found in standard injectable drug preparations.

<i>Catharanthus roseus</i> Species of flowering plant in the family Apocynaceae

Catharanthus roseus, commonly known as bright eyes, Cape periwinkle, graveyard plant, Madagascar periwinkle, old maid, pink periwinkle, rose periwinkle, is a perennial species of flowering plant in the family Apocynaceae. It is native and endemic to Madagascar, but is grown elsewhere as an ornamental and medicinal plant, and now has a pantropical distribution. It is a source of the drugs vincristine and vinblastine, used to treat cancer. It was formerly included in the genus Vinca as Vinca rosea.

<i>Vinca</i> alkaloid

Vinca alkaloids are a set of anti-mitotic and anti-microtubule alkaloid agents originally derived from the periwinkle plant Catharanthus roseus and other vinca plants. They block beta-tubulin polymerization in a dividing cell.

<span class="mw-page-title-main">Vindesine</span> Chemical compound

Vindesine, also termed Eldisine, is a semisynthetic vinca alkaloid derived from the flowering plant Catharanthus roseus. Like the natural and semisynthetic vinca alkaloids derived from this plant, vindesine is an inhibitor of mitosis that is used as a chemotherapy drug. By inhibiting mitosis, vinedsine blocks the proliferation of cells, particularly the rapidly proliferation cells of certain types of cancer. It is used, generally in combination with other chemotherapeutic drugs, in the treatment of various malignancies such as leukaemia, lymphoma, melanoma, breast cancer, and lung cancer.

<span class="mw-page-title-main">Mitotic inhibitor</span> Cell division inhibitor

A mitotic inhibitor, microtubule inhibitor, or tubulin inhibitor, is a drug that inhibits mitosis, or cell division, and is used in treating cancer, gout, and nail fungus. These drugs disrupt microtubules, which are structures that pull the chromosomes apart when a cell divides. Mitotic inhibitors are used in cancer treatment, because cancer cells are able to grow through continuous division that eventually spread through the body (metastasize). Thus, cancer cells are more sensitive to inhibition of mitosis than normal cells. Mitotic inhibitors are also used in cytogenetics, where they stop cell division at a stage where chromosomes can be easily examined.

Hyper-CVAD is a chemotherapy regimen used to treat some forms of leukemia, high-grade non-Hodgkin lymphoma, and lymphoblastic leukemia.

<span class="mw-page-title-main">Plant sources of anti-cancer agents</span>

Plant sources of anti-cancer agents are plants, the derivatives of which have been shown to be usable for the treatment or prevention of cancer in humans.

VAMP regimen or VAMP chemotherapy is a four-drug combination chemotherapy regimen, used today in the treatment of Hodgkin lymphoma. It was one of the earliest combination chemotherapy regimens, originally developed as a treatment for childhood leukemia by a group of researchers at the National Cancer Institute led by Emil Frei and Emil Freireich. The first clinical trial of VAMP began in 1961. Because it was the first time that four chemotherapeutic agents were used at once, the trial was highly controversial at its time. Although new combination chemotherapy regimens have replaced the use of VAMP in the treatment of childhood leukemia, VAMP is considered an important precursor to modern treatments, confirming the effectiveness of combination chemotherapy and leading to the use of combination chemotherapy regimens to treat other types of cancer.

Chemotherapy-induced peripheral neuropathy (CIPN) is a nerve-damaging side effect of antineoplastic agents in the common cancer treatment, chemotherapy. CIPN afflicts between 30% and 40% of patients undergoing chemotherapy. Antineoplastic agents in chemotherapy are designed to eliminate rapidly dividing cancer cells, but they can also damage healthy structures, including the peripheral nervous system. CIPN involves various symptoms such as tingling, pain, and numbness in the hands and feet. These symptoms can impair activities of daily living, such as typing or dressing, reduce balance, and increase risk of falls and hospitalizations. They can also give cause to reduce or discontinue chemotherapy. Researchers have conducted clinical trials and studies to uncover the various symptoms, causes, pathogenesis, diagnoses, risk factors, and treatments of CIPN.

"7+3" in the context of chemotherapy is an acronym for a chemotherapy regimen that is most often used today as first-line induction therapy in acute myelogenous leukemia, excluding the acute promyelocytic leukemia form, which is better treated with ATRA and/or arsenic trioxide and requires less chemotherapy.

<span class="mw-page-title-main">Strictosidine</span> Chemical compound

Strictosidine is a natural chemical compound and is classified as a glucoalkaloid and a vinca alkaloid. It is formed by the Pictet–Spengler condensation reaction of tryptamine with secologanin, catalyzed by the enzyme strictosidine synthase. Thousands of strictosidine derivatives are sometimes referred to by the broad phrase of monoterpene indole alkaloids. Strictosidine is an intermediate in the biosynthesis of numerous pharmaceutically valuable metabolites including quinine, camptothecin, ajmalicine, serpentine, vinblastine, vincristine and mitragynine.

<span class="mw-page-title-main">Dimerization of catharanthine and vindoline</span>

Catharanthine and vindoline are terpenoid indole alkaloids naturally produced within the Madagascar periwinkle plant whose dimerization produces the anti-cancer drugs vinblastine and vincristine. The precursor of catharanthine and vindoline is strictosidine, the common precursor of all indole alkaloids. The localization of catharanthine and vindoline within the plant tissue has been heavily studied in recent years with conflicting results. The dimerization of catharanthine and vindoline to form vinblastine and vincristine is catalyzed by a peroxidase and a reductase, and includes several intermediate compounds.
