Study Endpoints

Primary Endpoints

LNG Area Under the Concentration-time Curve (AUC0-8h) Calculated Based on Intensive LNG PK Samples Obtained From Individual Participants
Intensive LNG PK samples at pre-dose, and 0.5, 1, 1.5, 2, 3, 4, 6, and 8 hours post-dose

AUC for each participant was calculated from all available LNG concentrations measured over 8 hours using the linear up/log down version of trapezoidal rule (i.e., noncompartmental technique) using the software package Phoenix WinNonLin (Certara®). This version of the trapezoidal rule used linear interpolation between untransformed data up to Cmax, and between log-transformed data from Cmax through Clast. Assay lower limit of quantification (LLOQ) for LNG was 0.025 ng/mL; values \< LLOQ were imputed as 0 (if pre-dose) or as 0.0125 (if post-dose).

Secondary Endpoints

Number and Percentage of Participants Experiencing Either a Serious Adverse Event (SAE) or Adverse Event (AE) Potentially or Definitely Associated With Single Dose LNG Administration.
From Day 0 through study Day 28
Maximum Concentration (Cmax) of LNG
Intensive LNG PK samples at pre-dose, and 0.5, 1, 1.5, 2, 3, 4, 6, 8, 24, and 48 hours post-dose
Minimum Concentration (Cmin) of LNG
Intensive LNG PK samples at pre-dose, and 0.5, 1, 1.5, 2, 3, 4, 6, 8, 24, and 48 hours post-dose

Frequently asked questions about Levonorgestrel

What is Levonorgestrel used for in HIV Infections?

Levonorgestrel is a small molecule being studied for use in HIV Infections, specifically as an emergency contraceptive in women taking efavirenz-based antiretroviral therapy or rifampicin-containing anti-tuberculosis therapy. It is currently in Phase 2 clinical development and is investigational, not yet approved for this use.

What does Levonorgestrel target?

Levonorgestrel is a progestin hormone that works by binding to progesterone receptors, which prevents ovulation and fertilization. In the context of HIV Infections, it is being studied to evaluate its pharmacokinetics when combined with certain antiretroviral or anti-tuberculosis medications, which may affect its effectiveness as an emergency contraceptive.

Who makes Levonorgestrel?

Levonorgestrel is being developed by cbdMD, Inc., a company traded under the ticker YCBD. The company is conducting clinical research to evaluate the drug's use in HIV Infections, specifically in combination with other therapies.

What phase is Levonorgestrel in?

Levonorgestrel is in Phase 2 clinical development for HIV Infections. It is an investigational drug and has not been approved by regulatory authorities for this indication. One Phase 2 trial has been completed, and no active trials are currently listed.

What clinical trials is Levonorgestrel in?

Levonorgestrel has one completed Phase 2 clinical trial, NCT03819114, titled 'Pharmacokinetic Study to Evaluate Double-Dose Levonorgestrel Emergency Contraception in Combination With Efavirenz-Based Antiretroviral Therapy or Rifampicin-Containing Anti-Tuberculosis Therapy.' The trial enrolled 122 female participants aged 16 years and older across multiple countries, including the United States, Botswana, Brazil, Kenya, Malawi, South Africa, and Thailand.
