First-in-human or early safety and dose studies. Small groups. Not designed to prove a treatment works.
On a ClinicalTrials.gov record, Phase 1 (and Early Phase 1) usually means the main questions are safety, dose, and how the body handles the product. Groups are small. Some phase 1 studies enroll people with the disease; others enroll healthy volunteers.
A phase 1 listing is not evidence that the product is effective for you. It is also not an FDA approval. Read eligibility, visit burden, and the consent form with the study team.
PlainTrials applies this label only when the registry Phase field contains PHASE1 or EARLY_PHASE1. We do not reclassify studies.

Phase 1 / Phase 2: testing Ocrelizumab infusion for Schizo-Affective Type of PsychosisSome people who have what doctors currently call schizophrenia or bipolar disease may actually have a brain disease caused by auto-antibodies. Auto-antibodies are produced when the normal defense mechanism of the body goes wrong and begins to attack the body, similar to "friendly fire." Auto-antibodies attack brain receptors and then the person who has this problem begins to have hallucinations and other manifestations of schizophrenia, like feeling that people can see what they are thinking and also feeling that other people do not like them.

Phase 1: Surgery with Neoadjuvant stereotactic body radiation therapy for Hepatocellular CarcinomaHepatocellular carcinoma (HCC) is the fifth more common cancer in the world, with high mortality rates, due to the low number of patients who are eligible for therapy with curative intent, like surgical resection. Moreover, surgical resection is associated with a high risk of tumor recurrence, because of the tumor seeding through microscopic intrahepatic vessels that surround the tumor, the so-called "microvascular invasion".
