CAT intended to file an Investigational New Drug (IND) application for GCR-8015 in various CD22 positive B-cell malignancies, including Non-Hodgkin lymphoma and chronic lymphocytic leukemia, following a period of manufacturing development which is expected to be complete by the end of 2006 and to support the NCIs ongoing development of GCR-3888 in Hairy cell leukemia (HCL) and pediatric acute lymphoblastic leukemia (pALL).CAT-8015 exhibited a greater affinity for CD22 than its predecessor, CAT-3888 and CATs language such as "CAT will support the NCIs ongoing development of CAT-3888..." suggested at the time that their focus was on the second generation candidate.CAT was acquired by AstraZeneca, who also acquired MedImmune, combining the two into a biologics division. MedImmune renamed CAT-8015 to moxetumomab pasudotox.On 16 May 2013, AstraZeneca announced that CAT-8015 had started Phase III clinical trials. History
On 5 December 2008, orphan designation (EU/3/08/592) was granted by the European Commission to Medimmune Limited, United Kingdom, for murine anti-CD22 antibody variable region fused to truncated Pseudomonas exotoxin 38 for the treatment of hairy cell leukaemia. It was renamed to Moxetumomab pasudotox. The sponsorship was transferred to AstraZeneca AB, Sweden, in January 2019.On 17 July 2013, orphan designation (EU/3/13/1150) was granted by the European Commission to MedImmune Ltd, United Kingdom, for moxetumomab pasudotox for the treatment of B-lymphoblastic leukaemia / lymphoma.
The CAS Registry Number of the free base is 50-49-7, of the hydrochloride is 113-52-0, and of the embonate is 10075-24-8. History
The parent compound of imipramine, 10,11-dihydro-5H-dibenz[b,f]azepine (dibenzazepine), was first synthesized in 1899, but no pharmacological assessment of this compound or any substituted derivatives was undertaken until the late 1940s. Imipramine was first synthesized in 1951, as an antihistamine. The antipsychotic effects of chlorpromazine were discovered in 1952, and imipramine was then developed and studied as an antipsychotic for use in patients with schizophrenia. The medication was tested in several hundred patients with psychosis, but showed little effectiveness. However, imipramine was serendipitously found to possess antidepressant effects in the mid-1950s following a case report of symptom improvement in a woman with severe depression who had been treated with it. This was followed by similar observations in other patients and further clinical research. Subsequently, imipramine was introduced for the treatment of depression in Europe in 1958 and in the United States in 1959. Along with the discovery and introduction of the monoamine oxidase inhibitor iproniazid as an antidepressant around the same time, imipramine resulted in the establishment of monoaminergic drugs as antidepressants.In the late 1950s, imipramine was the first TCA to be developed (by Ciba). At the first international congress of neuropharmacology in Rome, September 1958 Dr Freyhan from the University of Pennsylvania discussed as one of the first clinicians the effects of imipramine in a group of 46 patients, most of them diagnosed as "depressive psychosis".
