Reducing Hypoxia in Patients With Coronavirus Disease (COVID-19) Using Topotecan With Standard of Care

October 27, 2021 updated by: National University Hospital, Singapore

Phase I Dose-escalation Study of Topotecan in Moderate-severe COVID-19 Patients

The primary objective of the phase 1 trial is to identify a dose of topotecan that will be safe to take forward into a Phase 2 trial, with no unexpected toxicities or drug-drug interactions with standard therapy for COVID-19. The investigators hypothesise that a single dose of low-dose Topotecan will blunt the expression of inflammatory genes in patients with moderate COVID-19, without cytotoxic side effects.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

4 fixed dosing levels (0.25 -0.5mg) of Topotecan will be evaluated in this trial, using sub-cytotoxic doses of Topotecan which are well below typical chemotherapy levels and shown not to cause myelosuppression in previously tested populations. The dose escalation will be in a standard 3+3 dose escalation design with 0.25 mg increments of Topotecan. The study aims to establish the recommended phase 2 dose (RP2D) of Topotecan in hypoxic patients with moderate to severe COVID-19.The RP2D is defined as the maximum safe dose at which 3 or more patients are found to have clinically relevant concentrations of Topotecan in the blood stream, without reaching anti-cancer concentrations in plasma (defined as Area under the curve (AUC)>150000) and without causing Grade 2/3/4 neutropenia (CTCAE5).

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study
