Gazyva Dosage Details: Form, Potency, Method of Administration, and Additional Information
In the realm of cancer treatment, Gazyva (obinutuzumab) emerges as a significant option for up to two years, depending on the patient's response to the drug and their specific condition. This prescription intravenous (IV) infusion, belonging to the CD20-directed cytolytic antibodies drug class, is approved by the Food and Drug Administration (FDA) for treating certain forms of cancer in adults.
The administration of Gazyva varies based on the condition being treated.
Chronic Lymphocytic Leukemia (CLL)
For CLL that hasn't been treated before, Gazyva is typically given in combination with chlorambucil over six 28-day cycles. Each cycle involves one or more infusions, with the standard dose being 1,000 mg per dose.
Follicular Lymphoma (FL)
In the case of relapsed or refractory FL, Gazyva is combined with bendamustine for six 28-day cycles, followed by Gazyva monotherapy at 1,000 mg for up to two years if the patient responds or stabilizes. For previously untreated FL, Gazyva may be combined with bendamustine, cyclophosphamide, vincristine, and prednisone (CVP), or cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP), followed by Gazyva monotherapy for a defined period if remission is achieved.
Dosage adjustments depend on various factors, including the patient's treatment history, disease status, response to treatment, the chemotherapy backbone used in combination, tolerance, and side effects.
The dosage for these treatment plans is 1,000 mg on days 1, 8, and 15 for the first cycle, and 1,000 mg on day 1 for subsequent cycles. Gazyva comes in one strength: 1,000 milligrams (mg) of Gazyva per 40 milliliters (mL) of solution.
Premedications may be recommended before receiving a Gazyva infusion to prevent infusion-related reactions. These may include steroids, pain relievers, fever reducers, and antihistamines.
It's important to note that treatment cycles for Gazyva in combination with these medications are typically 21 to 28 days long, with six to eight cycles being the standard. If a dose of Gazyva is missed, it should be rescheduled as soon as possible to maintain the treatment schedule. A medication reminder can help ensure appointments are not missed.
Gazyva is administered as an IV infusion by a healthcare professional in an infusion center, hospital, or doctor's office. The time taken for the infusion varies depending on the patient's tolerance and any infusion reactions. The Gazyva dosage prescribed depends on the type of condition being treated and any other medical conditions the patient may have.
For relapsed or refractory FL, Gazyva is given with another medication called bendamustine (Treanda). Gazyva is also used to treat certain forms of FL that haven't been treated before. When continuing Gazyva as a long-term treatment, bendamustine, CVP, or CHOP are discontinued at some point. Gazyva is also used to treat follicular lymphoma (FL) that's been treated with another medication called rituximab (Rituxan) and the cancer has relapsed or is refractory.
In summary, Gazyva is administered mainly in six to eight treatment cycles (each cycle lasting either 21 or 28 days depending on chemotherapy used) followed by monotherapy in FL patients who respond to treatment. If the cancer responds well or does not worsen, Gazyva may be continued for up to two years.
