chlorambucil and Minimal Disease, Residual

chlorambucil has been researched along with Minimal Disease, Residual in 17 studies

Chlorambucil: A nitrogen mustard alkylating agent used as antineoplastic for chronic lymphocytic leukemia, Hodgkin's disease, and others. Although it is less toxic than most other nitrogen mustards, it has been listed as a known carcinogen in the Fourth Annual Report on Carcinogens (NTP 85-002, 1985). (Merck Index, 11th ed)
chlorambucil : A monocarboxylic acid that is butanoic acid substituted at position 4 by a 4-[bis(2-chloroethyl)amino]phenyl group. A chemotherapy drug that can be used in combination with the antibody obinutuzumab for the treatment of chronic lymphocytic leukemia.

Number of Participants With Adverse Events (AEs)

An adverse event is any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with the treatment. An adverse event can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a pharmaceutical product, whether or not considered related to the pharmaceutical product. Preexisting conditions which worsen during a study are also considered as adverse events. AEs, including AEs of Special Interest and AEs of Particular Interest, were reported based on the national cancer institute common terminology criteria for AEs, Version 4.0 (NCI-CTCAE, v4.0). Reported are the number of subjects with AEs, Grade 3-5 AEs, and Serious Adverse Events (SAEs). (NCT01905943)
Timeframe: Baseline up to time of primary completion (3 years)

Number of Participants With Adverse Events of Particular Interest (AEPIs)

"The following AEs were defined as AEPIs: AEs with the preferred term Progressive multifocal leukoencephalopathy (PML), hepatitis B reactivation defined as AEs with preferred term containing Hepatitis B or hepatitis acute, thrombocytopenia defined via Roche MedDRA basket subgroup haematopoietic thrombocytopenia, second malignancies defined as AEs from the SOC Neoplasms benign, malignant and unspecified starting 6 months after the first study drug intake, second malignancies based on standardised MedDRA queries (SMQ) starting 6 months after the first study drug intake based on the MedDRA SMQ Malignant or unspecified tumours, in which benign neoplasms are not included, Cardiac events including AEs from the SOC Cardiac disorders, and hemorrhagic events defined via Roche MedDRA basket subgroup Haemorrhagic events. Reported are number of participants with total AEPIs and each of the AEPI categories." (NCT01905943)
Timeframe: Baseline up to time of primary completion (3 years)

Number of Participants With Adverse Events of Special Interest (AESIs)

"The following AEs were defined as AESIs: AEs with the preferred term Tumour Lysis Syndrome (TLS), Infusion-Related Reactions (IRRs) defined as AEs that occurred during or within 24 hours of the completion of obinutuzumab infusion and were assessed as related to obinutuzumab by the Investigator, Infections defined as AEs from System Organ Class (SOC) Infections and infestations and AEs with the preferred term Neutropenia. Reported are number of participants with total AESIs, IRRs, Infections, Neutropenia and TLS." (NCT01905943)

Percentage of Participants With Minimal Residual Disease (MRD)-Negativity as Assessed by Flow Cytometry

MRD-negativity was defined as the presence of less than 1 chronic lymphocytic leukemia (CLL) cell per 10,000 leukocytes in blood and bone marrow as assessed by flow cytometry 3 months after last dose of study treatment (i.e. at final response assessment [FRA] visit). (NCT01905943)
Timeframe: 3 months after the last dose of study treatment (up to approximately 5 years)
