What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests a cream with 5% tranexamic acid (also known as TXA, Cyklokapron, or Lysteda) to determine its effectiveness in lightening dark spots left by acne, known as postinflammatory hyperpigmentation. Many individuals cannot tolerate the usual treatments, but this cream may offer easier use with fewer side effects. Participants will apply the cream to dark spots on one side of their face, while the other side receives a cream without the active ingredient for comparison. Those with dark spots from acne on both sides of their face who have not used certain skin products in the last three months may be suitable for this trial. As a Phase 2 trial, this research measures the treatment's effectiveness in an initial, smaller group, allowing participants to contribute to potential new solutions for acne-related hyperpigmentation.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but you cannot have used certain skin treatments like hydroquinone, kojic acid, tretinoin, adapalene, tazarotene, or azaleic acid in the past 3 months.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research has shown that topical tranexamic acid is generally safe and well-tolerated. Studies on its use for skin conditions like melasma indicate that it rarely causes serious side effects. Some individuals might experience mild skin issues such as redness, irritation, or dryness at the application site. These effects are typically not serious and usually resolve on their own. Participants in the trial should monitor their skin's reaction and report any concerns to the study team. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising?

Unlike the standard treatments for postinflammatory hyperpigmentation from acne, which often involve topical lightening agents like hydroquinone or retinoids, tranexamic acid offers a fresh approach. Tranexamic acid is unique because it works by inhibiting melanin synthesis, potentially reducing pigmentation more effectively. Researchers are excited about its potential to provide a targeted treatment that minimizes dark spots without the irritation sometimes associated with other depigmenting agents. Also, being applied topically, it offers a convenient and non-invasive option for patients.

What evidence suggests that tranexamic acid might be an effective treatment for dark spots from acne?

Research has shown that a 5% tranexamic acid cream can help treat skin discoloration. It speeds up the healing of darkened skin caused by damage or conditions like melasma, similar to dark spots left by acne. Unlike hydroquinone, a common treatment that some find hard to tolerate, tranexamic acid is easier to use and has fewer side effects. In this trial, participants will apply topical tranexamic acid to the dark spots on one side of their face, while the other side will receive a vehicle cream without medication. Studies have found that both oral and topical tranexamic acid can reduce dark spots, suggesting it could be a good option for those dealing with acne-related dark spots. ^{4 6 7 8 9}

Published Research Related to This Trial

In a study of 60 patients undergoing bilateral total knee arthroplasty, intravenous tranexamic acid (TXA) significantly reduced total blood loss and the need for blood transfusions compared to the control group, indicating its efficacy in managing perioperative blood loss.

The use of TXA did not increase the risk of deep vein thrombosis or other thromboembolic events, suggesting it is a safe option for patients undergoing knee surgery.

In a study of 273 adult trauma patients receiving tranexamic acid (TXA) at a U.S. Level I trauma center, the overall mortality rate within 28 days was 12.8%, which is comparable to the 14.5% mortality rate observed in the CRASH-2 trial, indicating that TXA is effective in reducing mortality in traumatic hemorrhage.

However, the incidence of acute thromboembolic events was higher in this cohort at 6.6%, compared to 2.0% in the CRASH-2 trial, suggesting that while TXA is beneficial, it may also carry a higher risk of thromboembolic complications in certain patient populations.

In a study of 164 patients undergoing total hip replacement, a single injection of 30 mg/kg tranexamic acid (TXA) was found to be as effective as a continuous infusion in reducing blood loss, with no significant difference in mean blood loss between the two methods.

Both treatment methods were safe, with no reported deaths or major thromboembolic events within 90 days post-surgery, suggesting that the single injection is a practical and effective option for routine use in these patients.

Tranexamic acid (TxA) significantly reduces the volume of hematomas after total knee arthroplasty (TKA), with a decrease from 526 mL in the control group to 337 mL in the TxA group, indicating its efficacy in minimizing blood loss.

Despite the reduction in hematoma volume, TxA did not lead to a significant decrease in morphine consumption for pain management or improve rehabilitation outcomes within the first six months post-surgery.

A meta-analysis of 28 randomized controlled trials involving 4,200 participants found that combined administration of tranexamic acid (TXA) significantly reduces total blood loss and postoperative hemoglobin drop compared to using TXA through a single route (oral, intravenous, or topical).

Oral administration of TXA showed similar efficacy to intravenous or topical routes, indicating that it can be an effective alternative for reducing blood loss in total knee arthroplasty.
