Humans must obtain vitamin B9 (folate) from plant-based diet. The sources as well as the effect of food processing are discussed in detail. Industrial production, fortification and biofortification, kinetics, and physiological role in humans are described. As folate deficiency leads to several pathological states, current opinions toward prevention through fortification are discussed. Claimed risks of increased folate intake are mentioned as well as analytical ways for measurement of folate.

At first recurrence, platinum-sensitive ovarian cancer (PSOC) is frequently treated with platinum-based chemotherapy doublets plus bevacizumab, then single-agent bevacizumab. Most patients' disease progresses within a year after chemotherapy, emphasizing the need for novel strategies. Mirvetuximab soravtansine-gynx (MIRV), an antibody-drug conjugate, comprises a folate receptor alpha (FRα)-binding antibody and tubulin-targeting payload (maytansinoid DM4). In FRα-high PSOC, MIRV plus bevacizumab previously showed promising efficacy (objective response rate, 69% [95% CI: 41-89]; median progression-free survival, 13.3 months [95% CI: 8.3-18.3]; median duration of response, 12.9 months [95% CI: 6.5-15.7]) and safety. The Phase III randomized GLORIOSA trial will evaluate MIRV plus bevacizumab vs. bevacizumab alone as maintenance therapy in patients with FRα-high PSOC who did not have disease progression following second-line platinum-based doublet chemotherapy plus bevacizumab.Clinical Trial Registration: ClinicalTrials.gov ID: NCT05445778; GOG.org ID: GOG-3078; ENGOT.ESGO.org ID: ENGOT-ov76.

Most patients with ovarian cancer are initially treated with platinum-based chemotherapy. If the cancer reappears/recurs after more than 6 months following this therapy, it is called platinum-sensitive ovarian cancer (PSOC). Patients with PSOC usually receive additional platinum-based chemotherapy along with bevacizumab, a drug that reduces tumor growth by decreasing its blood supply. If patients improve or are stable on this therapy, they are usually kept on bevacizumab alone for ‘maintenance therapy’. Unfortunately, this maintenance therapy does not work long-term in all patients, so better long-term treatments are needed. The GLORIOSA (NCT05445778) clinical trial will compare maintenance therapy with bevacizumab alone to maintenance therapy with bevacizumab plus a drug called mirvetuximab soravtansine-gynx (MIRV) to determine which therapy leads to better results in patients with PSOC. MIRV is made up of an antibody that binds to a specific protein (folate receptor alpha [FRα]) on cancer cells to directly deliver a cancer-killing drug. MIRV received US FDA approval to be used as a therapy for patients with ovarian cancer who are resistant to platinum-based chemotherapy and express high levels of FRα. The GLORIOSA trial will study maintenance therapy with MIRV plus bevacizumab in patients with PSOC who have not had cancer progression after second-line platinum-based chemotherapy plus bevacizumab, and whose cancer expresses high amounts of FRα. The main purpose of this trial is to determine if MIRV plus bevacizumab leads to better patient survival and decreases cancer growth and spread when compared with bevacizumab alone.
