The recognition that the people in the United States had EM led to the recognition that "Lyme arthritis" was one manifestation of the same tick-borne condition known in Europe.Before 1976, the elements of B. burgdorferi sensu lato infection were called or known as tick-borne meningopolyneuritis, Garin-Bujadoux syndrome, Bannwarth syndrome, Afzeliuss disease, Montauk Knee or sheep tick fever. Since 1976 the disease is most often referred to as Lyme disease, Lyme borreliosis or simply borreliosis.In 1980, Steere, et al., began to test antibiotic regimens in adults with Lyme disease. In the same year, New York State Health Dept. epidemiologist Jorge Benach provided Willy Burgdorfer, a researcher at the Rocky Mountain Biological Laboratory, with collections of I. dammini [scapularis] from Shelter Island, New York, a known Lyme-endemic area as part of an ongoing investigation of Rocky Mountain spotted fever. In examining the ticks for rickettsiae, Burgdorfer noticed "poorly stained, rather long, irregularly coiled spirochetes." Further examination revealed spirochetes in 60% of the ticks. Burgdorfer credited his familiarity with the European literature for his realization that the spirochetes might be the "long-sought cause of ECM and Lyme disease." Benach supplied him with more ticks from Shelter Island and sera from people diagnosed with Lyme disease. University of Texas Health Science Center researcher Alan Barbour "offered his expertise to culture and immunochemically characterize the organism." Burgdorfer subsequently confirmed his discovery by isolating, from people with Lyme disease, spirochetes identical to those found in ticks.
Among the patients enrolled at the time of the data cutoff the overall response rate was 61% in the total patient population (42% complete response and 19% partial response) and in patients with relapsing or refractory diffuse large B-cell lymphoma (DLBCL) the overall response rate was 57% (43% complete response and 14% partial response). History
Loncastuximab tesirine was granted orphan drug designation by the U.S. Food and Drug Administration (FDA) for the treatment of diffuse large B-cell lymphoma. Society and culture
Legal status
On 15 September 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 marketing authorization for the medicinal product Zynlonta, intended for the treatment of adults with diffuse large B-cell lymphoma (DLBCL) and high-grade B-cell lymphoma (HGBL). The applicant for this medicinal product is ADC Therapeutics (NL) B.V.

Research
Given its mechanism of action, loncastiximab tesirinine may be appealing in patients ineligible for CAR-T cell therapy. References
