Cholic Acid: From Bile Acid Physiology to Predicted HIV Infectious Disease

One-Sentence Summary

Cholic acid is a naturally occurring primary bile acid; this evidence pack does not document a formally established original indication, though cholic acid is known outside this dataset for bile acid replacement therapy. The TxGNN model's top-ranked prediction is HIV infectious disease, but the supporting evidence is weak and partially contradictory — the associated literature describes spermicidal/virucidal use in contraceptive sponges and blood-product viral inactivation, and one study reports that cholic acid derivatives actually enhance HIV-1 replication. With 0 clinical trials and 9 publications, none of which demonstrate an antiretroviral therapeutic effect, the evidence does not currently support this prediction.

Quick Overview

Item	Content
Original Indication	Not documented in this dataset (`original_indications` is empty; cholic acid is generally known as a natural primary bile acid used in bile acid replacement therapy, but this is not captured in the evidence pack)
Predicted New Indication	HIV infectious disease
TxGNN Prediction Score	99.79%
Evidence Level	L5
Germany Market Status	✗ Not marketed
Number of Authorizations	0
Recommended Decision	Hold

Why is This Prediction Reasonable?

Currently, detailed mechanism of action data is not available for cholic acid in this evidence pack (marked as a Blocking-priority data gap, DG002). Without MOA data, there is no pharmacological basis provided in this pack to link cholic acid to antiretroviral activity.

The literature retrieved for this prediction does not describe a mechanism consistent with treating HIV infection. Most papers concern the use of sodium cholate as a spermicidal/virucidal agent in vaginal contraceptive sponges (e.g., Protectaid) or as an agent for viral inactivation of blood products (tri-n-butyl phosphate/sodium cholate treatment of plasma-derived factor concentrates) — these are barrier/disinfection contexts, not systemic antiretroviral therapy. More concerning, one study (PMID 16610808) found that amino-functionalized cholic acid derivatives induced HIV-1 replication and syncytia formation in T cells, i.e., the opposite of a therapeutic effect.

Given the absence of MOA data, the absence of any clinical trial, and the presence of a directly contradictory in-vitro finding, this specific TxGNN-predicted association currently lacks mechanistic plausibility and should not be advanced without independent confirmatory pharmacology.

Clinical Trial Evidence

Currently no related clinical trials registered.

7688380	1993	Clinical/microbicide study	Human Reproduction	Sodium cholate (in the Protectaid sponge, F-5 Gel) shows dose-dependent in-vitro spermicidal and anti-HIV-1 reverse transcriptase inhibitory activity; a barrier-contraceptive/microbicide effect, not systemic antiviral therapy

Safety Considerations

Please refer to the package insert for safety information.

(Note: safety.key_warnings, contraindications, and ddi are all marked as data gaps in this pack; TFDA label warnings/contraindications are flagged as a Blocking data gap (DG001) that must be resolved before any S1 safety assessment.)

Conclusion and Next Steps

Decision: Hold

Rationale: No clinical trials support cholic acid for HIV infectious disease, the mechanism of action is undocumented (Blocking data gap), and one in-vitro study directly contradicts the predicted therapeutic direction. Evidence level is L5 — model prediction only, without supportive actual studies.

To proceed, the following is needed:

Resolve DG001 (TFDA/BfArM label warnings and contraindications) — currently blocking any S1 safety assessment
Resolve DG002 (mechanism of action data via DrugBank) — needed for mechanistic plausibility review
Independent pharmacological studies clarifying why the TxGNN model links cholic acid to HIV infectious disease, given the contradictory in-vitro signal (PMID 16610808)
Consider re-evaluating lower-ranked candidates in this pack (e.g., "vitamin deficiency disorder," rank 5) which show stronger, mechanistically coherent evidence (an active Cholbam patient registry, NCT03115086, and multiple case series on bile acid synthesis disorders) more consistent with cholic acid's known biology
