Medical uses
In the US, ciltacabtagene autoleucel is indicated for the treatment of adults with relapsed or refractory multiple myeloma after four or more prior lines of therapy, including a proteasome inhibitor, an immunomodulatory agent, and an anti-CD38 monoclonal antibody.In the EU it is indicated for the treatment of adults with relapsed and refractory multiple myeloma, who have received at least three prior therapies, including an immunomodulatory agent, a proteasome inhibitor and an anti-CD38 antibody and have demonstrated disease progression on the last therapy. History
The safety and efficacy of ciltacabtagene autoleucel were evaluated in CARTITUDE-1 (NCT03548207), an open label, multicenter clinical trial evaluating ciltacabtagene autoleucel in 97 participants with relapsed or refractory multiple myeloma who received at least three prior lines of therapy which included a proteasome inhibitor, an immunomodulatory agent, and an anti-CD38 monoclonal antibody and who had disease progression on or after the last chemotherapy regimen; 82% had received four or more prior lines of antimyeloma therapy.The U.S. Food and Drug Administration (FDA) granted the application for ciltacabtagene autoleucel priority review, breakthrough therapy, and orphan drug designations.

Legal status
On 24 March 2022, the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) adopted a positive opinion, recommending the granting of a conditional marketing authorization for the medicinal product Carvykti, intended for the treatment of adults with relapsed and refractory multiple myeloma. The applicant for this medicinal product is Janssen-Cilag International NV. Ciltacabtagene autoleucel was approved for medical use in the European Union in May 2022. References

Descriptions of lead poisoning date to at least 2000 BC, while efforts to limit leads use date back to at least the 16th century. Concerns for low levels of exposure began in the 1970s with there being no safe threshold for lead exposure. Classification
Classically, "lead poisoning" or "lead intoxication" has been defined as exposure to high levels of lead typically associated with severe health effects. Poisoning is a pattern of symptoms that occur with toxic effects from mid to high levels of exposure; toxicity is a wider spectrum of effects, including subclinical ones (those that do not cause symptoms). However, professionals often use "lead poisoning" and "lead toxicity" interchangeably, and official sources do not always restrict the use of "lead poisoning" to refer only to symptomatic effects of lead.The amount of lead in the blood and tissues, as well as the time course of exposure, determine toxicity. Lead poisoning may be acute (from intense exposure of short duration) or chronic (from repeat low-level exposure over a prolonged period), but the latter is much more common. Diagnosis and treatment of lead exposure are based on blood lead level (the amount of lead in the blood), measured in micrograms of lead per deciliter of blood (μg/dL). Urine lead levels may be used as well, though less commonly. In cases of chronic exposure, lead often sequesters in the highest concentrations first in the bones, then in the kidneys.
