Description

Chlorambucil is an alkylating agent used in the treatment of chronic lymphocytic leukemia (CLL), non-Hodgkin's lymphoma, and multiple myeloma. It was first synthesized in the 1950s and has been used clinically for decades. The synthesis involves a multi-step process starting with phenylalanine. Chlorambucil exerts its effects by binding to DNA and preventing its replication, thereby inhibiting the growth of cancer cells. It has also been studied for its potential use in other conditions, including autoimmune diseases and organ transplantation. Its importance lies in its ability to effectively treat certain types of cancers while having a manageable toxicity profile. It is still studied today to optimize its use and explore new applications in cancer treatment.'

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) [Medical Subject Headings (MeSH), National Library of Medicine, extracted Dec-2023]

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.

Effects

Chlorambucil has been used for many years for the treatment of low-grade B-cell lymphoproliferative disorders. It has been shown to be detoxified by human glutathione transferase Pi (GST P1-1), an enzyme often found over-expressed in cancer tissues.

Treatment

Chlorambucil (CLB) treatment is used in chronic lymphocytic leukemia (CLL) resistance to CLB develops in association with accelerated repair of CLB-induced DNA damage. ChlorambUCil treatment was responsible for a decrease in circulating T4+ and T8+ cells. T lymphocyte function was slightly improved during relapses.

Roles (5)

RoleDescription
alkylating agentHighly reactive chemical that introduces alkyl radicals into biologically active molecules and thereby prevents their proper functioning. It could be used as an antineoplastic agent, but it might be very toxic, with carcinogenic, mutagenic, teratogenic, and immunosuppressant actions. It could also be used as a component of poison gases.
carcinogenic agentA role played by a chemical compound which is known to induce a process of carcinogenesis by corrupting normal cellular pathways, leading to the acquistion of tumoral capabilities.
antineoplastic agentA substance that inhibits or prevents the proliferation of neoplasms.
immunosuppressive agentAn agent that suppresses immune function by one of several mechanisms of action. Classical cytotoxic immunosuppressants act by inhibiting DNA synthesis. Others may act through activation of T-cells or by inhibiting the activation of helper cells. In addition, an immunosuppressive agent is a role played by a compound which is exhibited by a capability to diminish the extent and/or voracity of an immune response.
drug allergenAny drug which causes the onset of an allergic reaction.

Change in Best-corrected Visual Acuity (Change in the Numbers of Letters Read From a Standard ETDRS Eye Chart) From Baseline to 24 Months in Eyes With Uveitis

Best-corrected visual acuity was measured as the number of letters read from standard logarithmic visual acuity charts by study-certified examiners who were masked to treatment. Visual acuity was measured at all study visits. The primary outcome was eye-specific change in visual acuity from baseline to 2-year follow-up. Positive change values indicate improved vision while negative change values indicate vision has gotten worse. A change of 7.5 letters is considered clinically meaningful. (NCT00132691)

Kaplan-Meier Estimate of Progression Free Survival (PFS) With a Later Cut-off Date of 14 March 2014

Progression-free survival was defined as the time from randomization to the first documented progression confirmed per investigator's assessment or death due to any cause on study, whichever occurred first. Progressive disease included lymphadenopathy, an appearance of any new lesion such as enlarged lymph nodes (> 1.5 cm), splenomegaly, hepatomegaly or other organ infiltrates, an increase by 50% or more in greatest determined diameter of any previous site or an increase by 50% or more in the sum of the product of diameters of multiple nodes. The progression date was assigned to the earliest time when any progression was observed without prior missing assessments. If withdrawal of consent or lost to follow-up occurred before documented progression or death, then these observations were censored at the date when the last complete tumor assessments determined a lack of progression.

Molecular remission was defined as a minimal residual disease (MRD)-negative result at the end of treatment (assessment that occurred between 56 days and 6 months of last treatment). Molecular remission was assessed for all patients using a blood sample. Additionally, a bone marrow sample was obtained from patients whom the investigator assumed to have a complete response, consistent with the IWCLL guidelines. A combined analysis of blood and bone marrow results was conducted. A patient was considered MRD negative if result was less than 1 chronic lymphocytic leukemia (CLL) cell in 10000 leukocytes (MRD value < 0.0001) based on the method of allele specific polymerase chain reaction (ASO-PCR).

Mean Change From Baseline in the Immunoglobulins (Ig) Antibodies IgA, IgG, and IgM at the Indicated Time Points

Immunoglobulins, or antibodies, are large proteins used by the immune system to identify and neutralize foreign particles such as bacteria and viruses. Their normal blood levels indicate proper immune status. Low levels indicate immuno-suppression. IgA, IgG, and IgM were measured in the blood samples of the participants. Baseline IgA, IgG, and IgM values are the last pre-dose assessment values performed on Cycle 1-Day 1. Change from Baseline was calculated as the post-Baseline value minus the Baseline value. Immunoglobulins were measured at Cycle 1-Day 1, FU 1-PDFU 1, and FU 169-PDFU 169 for participants in CR, PR, and stable disease (SD). (NCT01563055)

Number of Participants With Improvement in Eastern Cooperative Oncology Group (ECOG) Performance Status (PS)

ECOG PS is a scale to assess disease progression, extent to which disease affects the daily living abilities and determines appropriate treatment and prognosis. It is scored on a scale of 0 to 5 as, 0 (fully active), 1 (restricted in physically strenuous activity but ambulatory and able to carry out work of a light or sedentary nature), 2 (ambulatory and capable of all self cares but unable to carry out any work activities, Up and about > 50% of waking hours), 3 (capable of only limited self cares, confined to bed or chair > 50% of waking hours), 4 (completely disabled, cannot carry on any self cares, totally confined to bed or chair), 5 (death). Improvement is defined as decrease from baseline by at least one step on the ECOG performance status scale (yes/no). Baseline was last pre-dose assessment performed on Cycle 1 Day 1(C1 D1). When C1 D1 was missing, the last assessment performed prior to pre-dose C1 D1 was used. It was performed on Day 1 of each cycle and follow-up (FU). (NCT01808326)

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)

Percentage of participants with EQ-5D-5L utility score increase ≥ 0.08 points over baseline at or prior to initiation of subsequent antineoplastic therapy. The EQ-5D-5L is a standardized non-disease specific instrument for describing and valuing health-related quality of life, comprising 5 dimensions of health (mobility, self -care, usual activities, pain/discomfort, and anxiety/depression) to describe the participant's current health state. Each dimension comprises 5 levels with corresponding numeric scores, where 1 indicates no problems, and 5 indicates extreme problems. A unique EQ-5D-5L health state is defined by combining the numeric level scores for each of the 5 dimensions and the total score is normalized from -0.594 to 1.000, with higher scores representing a better health state. An increase in the EQ-5D-5L total score indicates improvement. Participants with missing EQ-5D-5L data were considered not achieving clinically meaningful improvement. (NCT02264574)

Time to Worsening and Time to Improvement as Measured by Functional Assessment of Chronic Illness Therapy (FACIT)-Fatigue Total Score

Responses to the 13-item FACIT Fatigue Scale are reported on a 5-point categorical response scale ranging from 0 (not at all) to 4 (very much). The sum of all responses resulted in the FACIT-Fatigue score for a total possible score of 0 (worst score) to 52 (best score). Time to Worsening is defined as time interval (months) from randomization to first observation of deterioration. Worsening is defined as a decrease >= 3 points (on a 0-52 scale). Time to improvement is defined as the time interval (months) from randomization to the first observation of improvement. Improvement is defined as an increase >=3 points (on a 0-52 scale).

Time to Worsening as Measured by Using EuroQol 5 Dimension 5 Level Questionnaire (EQ-5D-5L)

"Time to worsening= time interval (months) from randomization to first observation of deterioration. EQ-5D-5L consists of a 5-item descriptive system and the EuroQol visual analog scale (EQ-5D VAS). EQ-5D-VAS self-rating records respondent's own assessment of his/her overall health status at time of completion, on scale of 0 (worst health you can imagine) to 100 (best health you can imagine). Worsening is defined as a decrease of >= 7 points (on a 0-100 scale).~EQ-5D-5L descriptive system comprises 5 dimensions of health (mobility, self -care, usual activities, pain/discomfort, and anxiety/depression) to describe participant's current health state. Responses for 5 dimensions are combined into a 5-digit number describing respondents health state that can be converted into a single index value or utility score (using the United Kingdom weights), ranging from -1 to 1, where lower scores indicate a worse health status. Worsening is defined as a decrease of >=0.08 points (on a 0-1 scale)." (NCT03462719)

Time to Worsening Measured by European Organization for Research and Treatment of Cancer-Quality of Life Questionnaire (EORTC QLQ)-C30)

Time to worsening= time interval from randomization to first observation of deterioration. EORTC QLQ-C30 includes 30 separate items: 5 functional scales (physical, role, emotional, cognitive, and social Functioning), 1 global health status (GHS) and QoL scale, 3 symptom scales (fatigue, nausea/vomiting, and pain), and 6 single items (dyspnea, insomnia, appetite loss, constipation, diarrhea, and financial difficulties). Each item, except GHS, is answered on 4-point scale (1=not at all to 4=very much) and GHS is measured on 1-7 scale: 1=very poor and 7=excellent. Scores derived using validated scoring algorithms as per EORTC QLQ-C30 Manual and linearly transformed in a range from 0-100. For functional and global QoL scales, higher scores=better level of functioning/QoL. For symptom-oriented scales, higher score=more severe symptoms. Worsening in functional and global health scores=decrease of >=10 points (on 0-100 scale) and in symptom scores=increase of >=10 points (on 0-100 scale). (NCT03462719)
