Proportion of patients with Complete Response (CR) or Partial Response (PR). Revised Response Criteria for Malignant Lymphoma categorises the response of the treatment of a patient's tumour to; CR: the disappearance of all evidence of disease; PR: ≥ 50% decrease in the sum of the perpendicular diameters (SPD) of the six largest dominant nodes plus no increase in the size of other nodes and no new sites of disease; Stable Disease (SD): less than a PR but not progressive disease; Relapsed Disease or PD: Any new lesion or increase by ≥ 50% of previously involved sites from nadir. Primary efficacy is based on Phase II patients only.

Fostamatinib is an investigational small molecule SYK inhibitor being studied for multiple conditions, including IgA nephropathy, warm antibody autoimmune hemolytic anemia, COVID-19, acute respiratory distress syndrome, lymphoma, and hidradenitis suppurativa. It is being developed by Rigel Pharmaceuticals, Inc. (RIGL).
Fostamatinib targets SYK (spleen tyrosine kinase), an enzyme involved in immune cell signaling. As a SYK inhibitor, it is designed to modulate inflammatory and autoimmune responses. This mechanism is being evaluated across several disease areas, including respiratory and autoimmune conditions.
Fostamatinib is being developed by Rigel Pharmaceuticals, Inc., a biopharmaceutical company traded on NASDAQ under the ticker RIGL. The company is conducting clinical trials to evaluate the drug's safety and efficacy across multiple indications.
Fostamatinib is in Phase 2 and Phase 3 clinical development. It has completed Phase 2 trials for IgA nephropathy and warm antibody autoimmune hemolytic anemia, and a Phase 3 trial for COVID-19. A Phase 2 trial for acute respiratory distress syndrome is planned but not yet recruiting.
Fostamatinib has been studied in several clinical trials, including NCT02112838 for IgA nephropathy, NCT02612558 for warm antibody autoimmune hemolytic anemia, and NCT04629703 for COVID-19. A Phase 2 trial for acute respiratory distress syndrome, NCT06564207, is planned but not yet recruiting.
Fostamatinib is also known as Fostamatinib in combination with chemotherapy, specifically with gemcitabine and nab-paclitaxel. This combination is being studied for potential use in lymphoma, though the drug is also being evaluated as a monotherapy for other conditions.
