Treanda

Name: Treanda

Uses of Treanda

Treanda is a prescription medication used to treat chronic lymphocytic leukemia (CLL). CLL is a type of cancer of the white blood cells. Treanda is also used to treat a type of non-Hodgkins lymphoma (NHL). NHL is a cancer that begins in a type of white blood cell that normally fights infection.

This medication may be prescribed for other uses. Ask your doctor or pharmacist for more information.

Treanda Precautions

Serious side effects have been reported with Treanda including the following:

  • Mild or serious allergic reactions. Immediately report rash, facial swelling, or difficulty breathing during or soon after infusion.
  • A decrease in white blood cells, platelets, and red blood cells. Your doctor will need to conduct labd to monitor for this. Report shortness of breath, significant fatigue, bleeding, fever, or other signs of infection.

Indications and Usage for Treanda

  Chronic Lymphocytic Leukemia (CLL)

Treanda® is indicated for the treatment of patients with chronic lymphocytic leukemia. Efficacy relative to first line therapies other than chlorambucil has not been established.

  Non-Hodgkin Lymphoma (NHL)

Treanda is indicated for the treatment of patients with indolent B-cell non-Hodgkin lymphoma that has progressed during or within six months of treatment with rituximab or a rituximab-containing regimen.

Contraindications

Treanda is contraindicated in patients with a known hypersensitivity (e.g., anaphylactic and anaphylactoid reactions) to bendamustine. [see Warnings and Precautions (5.3)]

Drug Interactions

No formal clinical assessments of pharmacokinetic drug-drug interactions between Treanda and other drugs have been conducted. 

Bendamustine's active metabolites, gamma-hydroxy bendamustine (M3) and N-desmethyl-bendamustine (M4), are formed via cytochrome P450 CYP1A2. Inhibitors of CYP1A2 (e.g., fluvoxamine, ciprofloxacin) have potential to increase plasma concentrations of bendamustine and decrease plasma concentrations of active metabolites.  Inducers of CYP1A2 (e.g., omeprazole, smoking) have potential to decrease plasma concentrations of bendamustine and increase plasma concentrations of its active metabolites.  Caution should be used, or alternative treatments considered if concomitant treatment with CYP1A2 inhibitors or inducers is needed. 

The role of active transport systems in bendamustine distribution has not been fully evaluated. In vitro data suggest that P-glycoprotein, breast cancer resistance protein (BCRP), and/or other efflux transporters may have a role in bendamustine transport.  

Based on in vitro data, bendamustine is not likely to inhibit metabolism via human CYP isoenzymes CYP1A2, 2C9/10, 2D6, 2E1, or 3A4/5, or to induce metabolism of substrates of cytochrome P450 enzymes.

Clinical Studies

Chronic Lymphocytic Leukemia (CLL)

The safety and efficacy of Treanda were evaluated in an open-label, randomized, controlled multicenter trial comparing Treanda to chlorambucil.  The trial was conducted in 301 previously-untreated patients with Binet Stage B or C (Rai Stages I - IV) CLL requiring treatment.  Need-to-treat criteria included hematopoietic insufficiency, B-symptoms, rapidly progressive disease or risk of complications from bulky lymphadenopathy. Patients with autoimmune hemolytic anemia or autoimmune thrombocytopenia, Richter’s syndrome, or transformation to prolymphocytic leukemia were excluded from the study.

The patient populations in the Treanda and chlorambucil treatment groups were balanced with regard to the following baseline characteristics: age (median 63 vs. 66 years), gender (63% vs. 61% male), Binet stage (71% vs. 69% Binet B), lymphadenopathy (79% vs. 82%), enlarged spleen (76% vs. 80%), enlarged liver (48% vs. 46%), hypercellular bone marrow (79% vs. 73%), “B” symptoms (51% vs. 53%), lymphocyte count (mean 65.7x109/L vs. 65.1x109/L), and serum lactate dehydrogenase concentration (mean 370.2 vs. 388.4 U/L).  Ninety percent of patients in both treatment groups had immuno-phenotypic confirmation of CLL (CD5, CD23 and either CD19 or CD20 or both).

Patients were randomly assigned to receive either Treanda at 100 mg/m2, administered intravenously over a period of 30 minutes on Days 1 and 2 or chlorambucil at 0.8 mg/kg (Broca’s normal weight) administered orally on Days 1 and 15 of each 28-day cycle.  Efficacy endpoints of objective response rate and progression-free survival were calculated using a pre-specified algorithm based on NCI working group criteria for CLL. 

The results of this open-label randomized study demonstrated a higher rate of overall response and a longer progression-free survival for Treanda compared to chlorambucil (see Table 5). Survival data are not mature.

* CR was defined as peripheral lymphocyte count ≤ 4.0 x 109/L, neutrophils ≥ 1.5 x 109/L, platelets >100 x 109/L, hemoglobin > 110g/L, without transfusions, absence of palpable hepatosplenomegaly, lymph nodes ≤ 1.5 cm, < 30% lymphocytes without nodularity in at least a normocellular bone marrow and absence of “B” symptoms. The clinical and laboratory criteria were required to be maintained for a period of at least 56 days.

** nPR was defined as described for CR with the exception that the bone marrow biopsy shows persistent nodules.

† PR was defined as ≥ 50% decrease in peripheral lymphocyte count from the pretreatment baseline value, and either ≥50% reduction in lymphadenopathy, or ≥50% reduction in the size of spleen or liver, as well as one of the following hematologic improvements: neutrophils ≥ 1.5 x 109/L or 50% improvement over baseline, platelets >100 x 109/L or 50% improvement over baseline, hemoglobin >110g/L or 50% improvement over baseline without transfusions, for a period of at least 56 days.

†† PFS was defined as time from randomization to progression or death from any cause.

Kaplan-Meier estimates of progression-free survival comparing Treanda with chlorambucil are shown in Figure 1.

 Non-Hodgkin Lymphoma (NHL)

The efficacy of Treanda was evaluated in a single arm study of 100 patients with indolent B-cell NHL that had progressed during or within six months of treatment with rituximab or a rituximab-containing regimen.  Patients were included if they relapsed within 6 months of either the first dose (monotherapy) or last dose (maintenance regimen or combination therapy) of rituximab. All patients received Treanda intravenously at a dose of 120 mg/m2, on Days 1 and 2 of a 21-day treatment cycle.  Patients were treated for up to 8 cycles.  

The median age was 60 years, 65% were male, and 95% had a baseline WHO performance status of 0 or 1. Major tumor subtypes were follicular lymphoma (62%), diffuse small lymphocytic lymphoma (21%), and marginal zone lymphoma (16%).  Ninety-nine percent of patients had received previous chemotherapy, 91% of patients had received previous alkylator therapy, and 97% of patients had relapsed within 6 months of either the first dose (monotherapy) or last dose (maintenance regimen or combination therapy) of rituximab. 

Efficacy was based on the assessments by a blinded independent review committee (IRC) and included overall response rate (complete response + complete response unconfirmed + partial response) and duration of response (DR) as summarized in Table 6.
