The report provides a detailed analysis essential for establishing a tositumomab production plant. It encompasses all critical aspects necessary for tositumomab production, including the cost of tositumomab production, tositumomab plant cost, tositumomab production costs, and the overall tositumomab production plant cost. Additionally, the study covers specific expenditures associated with setting up and operating a tositumomab production plant. These encompass production processes, raw material requirements, utility requirements, infrastructure needs, machinery and technology requirements, manpower requirements, packaging requirements, transportation requirements, and more.
Tositumomab is a targeted cancer treatment made from a monoclonal antibody attached to radioactive iodine-131. It seeks out and destroys CD20-positive B-cells responsible for non-Hodgkin lymphoma (NHL), which is a common blood cancer affecting the lymph system. It is made for patients with relapsed or refractory low-grade, follicular, or transformed NHL who no longer respond to standard therapies like rituximab. It delivers radiation directly to tumour cells to shrink them while limiting damage to healthy tissues through its two-step dosing. It has overall response rates around two-thirds of patients and complete remissions in up to a third or more, especially in rituximab-failures.
The market for tositumomab is driven by its FDA approval for relapsed or refractory CD20-positive low-grade, follicular, or transformed NHL. The clinical efficacy shows high response rates in rituximab-failures, and niche demand for targeted radioimmunotherapy in patients exhausted by chemotherapy like CHOP or rituximab, which contributes to its market growth.
The competition from more convenient regimens like CHOP plus rituximab and its superiority over these standards in frontline follicular NHL support its demand. The high treatment costs per course, and complex logistics requiring specialised radiopharmaceutical handling facilities, trained nuclear medicine personnel, and patient isolation protocols influence industrial tositumomab procurement.
Raw Material for Tositumomab Production
According to the tositumomab production plant project report, the key raw materials used in the production of tositumomab include Murine B-cells, myeloma cells, CD20 antigen, and serum-free culture media.
Production Process of Tositumomab
The extensive tositumomab production cost report consists of the following major industrial production process:
- From maltose: The production of tositumomab starts with immunising mice against the CD20 antigen on B-cells. They are fused by their antibody-producing cells with myeloma cells to create hybridomas. Then these antibodies are grown in large bioreactors using serum-free media to produce the raw antibody. This is then purified through chromatography steps to get a pure tositumomab as the final product.
Tositumomab is a murine IgG2a lambda monoclonal antibody targeting CD20 that appears as a sterile, pyrogen-free, clear to opalescent, colourless to slightly yellow, preservative-free liquid concentrate. It has a molecular weight of 150 kDa with a molecular formula of C6416H9874N1688O1987S44. It has an isoelectric point of 8.68 with a hydrophobicity of -0.4144. It has a melting point of around 61 °C. It is formulated with 100 mg/mL maltose, 8.5 mg/mL sodium chloride, 1 mg/mL phosphate, and 1 mg/mL potassium hydroxide at pH ~7.2. It is covalently linked to iodine-131 (I-131) for radioimmunotherapy, exhibiting clearance of 68.2 mg/hr in NHL patients via opsonisation or human anti-murine antibody responses.
