Evaluate the Safety and Efficacy of BLEX 404 Oral Liquid Combined With Pemetrexed + Cisplatin Therapy

Starting soon · Phase 1/Phase 2

Conditions studied: Nonsquamous Nonsmall Cell Neoplasm of Lung

In brief

Maitake is reported with immunomodulatory functions against tumor growth in terms of its unique molecular structure, β-glucan polysaccharides within 1, 6 main chain having 1, 3 branches and a 1, 3 main chain having 1, 6 branches configuration. The β-glucan is identified as a main component of BLEX 404. Not only with therapeutic potential on several types of cancer, BLEX 404 has also shown the potential to improve hematopoiesis, granulocyte colony stimulating factor (G-CSF) production, and the cytotoxicity activity of immune cells in recent animal studies. Its antitumor effect on tumor-bearing mice is exerted by enhancing the immune system through activation of macrophages, T cells, and natural killer (NK) cells. The activation of antigen presenting cells (APCs) such as macrophages, dendritic cells (DCs) via BLEX 404 administration is in response to secretion of interleukin-12 (IL-12). BLEX 404 has been found to enhance the activity of immunocompetent cells such as helper T cells, cytotoxic T cells, and NK cells either by i.p injection or oral intake, therefore, it stimulates innate and adaptive immunity. BLEX 404 enhances hematopoiesis by increasing mouse bone marrow cell and human cord blood cell differentiation into granulocytes-macrophages (GMs), granulopoiesis and mobilization of granulocytes, and granulocyte macrophage colony-stimulating factor (GM-CSF) or G-CSF production. One related phase I healthy human trial by treating with Maitake D-fraction was examined in Italy. The published data of trial for solid tumor patients was in the year 2003 in Japan, and another for breast cancer patients was in the year 2009 in the United States executed by Memorial Sloan Kettering Cancer Center (MSKCC). Lately, same team amended IND for myelodysplastic syndromes (MDS) human trial. All those human experiences are the fundamental of developing BLEX 404 Oral Liquid.

• Willing and able to comply with all aspects of the treatment protocol.
• Provide written informed consent.

You may not qualify if…

• Women who are pregnant or breast feeding.
• Patients with brain metastasis but asymptomatic need not be excluded.
• Patients with autoimmune disease that requires systemic steroids or immunosuppression agents.
• Current enrollment in another clinical study or used any investigational drug or device within the past 28 days preceding informed consent.
• Patients with following treatment prior to Pemetrexed + Cisplatin Therapy: chemotherapy, immunotherapy, or biologic systemic anticancer therapy within 21 days of study entry (42 days for mitomycin and nitrosoureas); prior received taxanes in adjuvant therapy within 12 months; prior received polysaccharide-based drugs within 6 months; radiation therapy within 28 days (90 days for bone marrow exposure 20%); hormonal therapy within 28 days.
