Ventonix Tablet 10 mg Uses, Dosage, Side Effects, Food Interaction and all others data.

Ventonix Tablet 10 mg is a BCL-2 inhibitor that was initially approved by the FDA in April 2016 . Proteins in the B cell CLL/lymphoma 2 (BCL-2) family are important regulators of the apoptotic (programmed cell death) process , . Ventonix Tablet 10 mg is used to treat chronic lymphocytic leukemia (CLL) and certain types of small lymphocytic lymphoma . CLL is the most prevalent leukemia diagnosed in Western countries . Ventonix Tablet 10 mg was developed through reverse engineering of the BCL-2 protein family inhibitor, navitoclax . Ventonix Tablet 10 mg is approximately 10 times more potent than navitoclax with regard to induction of apoptosis in CLL cells . A new indication was approved in 2018 for the treatment patients with chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL), with or without 17p deletion, who have received at least one prior therapy . Previously, this drug was indicated only for patients with 17p gene deletion .

Ventonix Tablet 10 mg induces rapid and potent onset apoptosis of CLL cells, powerful enough to act within 24h and to lead to tumor lysis syndrome , , . Selective targeting of BCL2 with venetoclax has demonstrated a manageable safety profile and has been shown to induce significant response in patients with relapsed CLL (chronic lymphocytic leukemia) or SLL (small lymphocytic leukemia), including patients with poor prognostic features . This drug is not expected to have a significant impact on the cardiac QT interval . Ventonix Tablet 10 mg has demonstrated efficacy in various types of lymphoid malignancies, including relapsed/ refractory CLL harboring deletion 17p, with an overall response rate of approximately 80% .

Uses

Ventonix Tablet 10 mg is a BCL-2 inhibitor used to treat chronic lymphocytic leukemia, small lymphocytic lymphoma, or acute myeloid leukemia.

A BCL-2 inhibitor indicated for the treatment of patients with chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL), with or without 17p deletion, who have received at least one prior therapy .

Ventonix Tablet 10 mg is also used to associated treatment for these conditions: Chronic Lymphocytic Leukaemia (CLL), Small Lymphocytic Lymphoma

How Ventonix Tablet 10 mg works

Proteins in the B cell CLL/lymphoma 2 (BCL-2) family are necessary regulators of the apoptotic (anti-cell programmed death) process. This family comprises proapoptotic and prosurvival proteins for various cells. Cancer cells evade apoptosis by inhibiting programmed cell death (apoptosis). The therapeutic potential of directly inhibiting prosurvival proteins was unveiled with the development of navitoclax, a selective inhibitor of both BCL-2 and BCL-2-like 1 (BCL-X(L)), which has demonstrated clinical efficacy in some BCL-2-dependent hematological cancers . Selective inhibition of BCL-2 by venetoclax, sparing BCL-xL enables therapeutic induction of apoptosis without the negative effect of thrombocytopenia , . Ventonix Tablet 10 mg helps restore the process of apoptosis by binding directly to the BCL-2 protein, displacing pro-apoptotic proteins, leading to mitochondrial outer membrane permeabilization and the activation of caspase enzymes. In nonclinical studies, venetoclax has shown cytotoxic activity in tumor cells that overexpress BCL-2 .

Toxicity

Acute toxicity: oral toxicity (LD50) >2001 mg/kg (mouse) .

Ventonix Tablet 10 mg may cause embryo-fetal harm when administered to a pregnant woman. Patients should avoid pregnancy during treatment. A risk to human male fertility exists based on the results of testicular toxicity (germ cell loss) seen in dogs at exposures as low as 0.5 times the human AUC exposure at the recommended dose .

Carcinogenicity studies have not yet been performed with venetoclax .

Ventonix Tablet 10 mg was not shown to be mutagenic in an in vitro bacterial mutagenicity (Ames) assay, did not induce aberrations in an in vitro chromosome aberration assay with human peripheral blood lymphocytes. It was not clastogenic in an in vivo mouse bone marrow micronucleus assay at doses up to 835 mg/kg. The M27 metabolite was negative for genotoxic activity during both in vitro Ames and chromosome aberration assays .

Food Interaction

  • Avoid grapefruit products. Grapefruit inhibits CYP3A metabolism, which may increase the serum concentration of venetoclax.
  • Avoid St. John's Wort. This herb induces CYP3A metabolism and may reduce serum levels of venetoclax.
  • Take at the same time every day.
  • Take with a full glass of water.
  • Take with food.

[Major] ADJUST DOSING INTERVAL: Food enhances the oral bioavailability of venetoclax.

Relative to fasting conditions, venetoclax systemic exposure (AUC) increased by approximately 3.4-fold when administered with a low-fat meal and by 5.1- to 5.3-fold when administered with a high-fat meal.

GENERALLY AVOID: Grapefruit juice may increase the plasma concentrations of venetoclax.

The proposed mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruit.

In general, the effect of grapefruit juice is concentration-, dose- and preparation-dependent, and can vary widely among brands.

Certain preparations of grapefruit juice (e.g., high dose, double strength) have sometimes demonstrated potent inhibition of CYP450 3A4, while other preparations (e.g., low dose, single strength) have typically demonstrated moderate inhibition.

Increased venetoclax exposure may potentiate the risk of tumor lysis syndrome, particularly at initiation of therapy and during the dosage ramp-up phase, as well as other adverse effects such as diarrhea, nausea, vomiting, neutropenia, anemia, and thrombocytopenia.

MANAGEMENT: Ventonix Tablet 10 mg should be administered with a meal and water at approximately the same time each day.

Patients should avoid consumption of grapefruit products, Seville oranges, and starfruit during treatment with venetoclax.

Ventonix Tablet 10 mg Disease Interaction

Moderate: hepatic impairment, neutropenia, TLS/renal, vaccination

Volume of Distribution

The population estimate for apparent volume of distribution (Vdss/F) of venetoclax ranged from 256-321 L .

Elimination Route

Following several oral administrations after a meal, the maximum plasma concentration of venetoclax was reached 5-8 hours after the dose . Ventonix Tablet 10 mg steady state AUC (area under the curve) increased proportionally over the dose range of 150-800 mg. After a low-fat meal, venetoclax mean (± standard deviation) steady-state Cmax was 2.1 ± 1.1 μg/mL and AUC0-24 was 32.8 ± 16.9 μg•h/mL at the 400 mg once daily dose .

When compared with the fasted state, venetoclax exposure increased by 3.4 times when ingested with a low-fat meal and 5.2 times with a high-fat meal. When comparing low versus high fat, the Cmax and AUC were both increased by 50% when ingested with a high-fat meal. The FDA label indicataes that venetoclax should be taken with food , .

Half Life

The half-life of venetoclax is reported to be 19-26 hours, after administration of a single 50-mg dose , .

Clearance

Mainly hepatic .

Elimination Route

After single oral administration of 200 mg radiolabeled [14C]-venetoclax dose to healthy subjects, >99.9% of the dose was found in feces and Label.
