Pregnenolone + DHEA for Lower Back Pain
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests two natural molecules, Pregnenolone and DHEA (Dehydroepiandrosterone), to determine their effectiveness in reducing chronic lower back pain. Researchers seek new, safe, and effective treatments for chronic pain, particularly for Veterans who often face pain impacting their mental health and quality of life. Participants will receive either Pregnenolone, DHEA, or a placebo (a non-active substance) to compare the treatments' effectiveness. Veterans experiencing lower back pain on most days for at least six months, with no recent changes in pain medication, might be suitable for this study. As a Phase 2 trial, this research measures the treatment's effectiveness in an initial, smaller group, offering participants a chance to contribute to developing potentially effective pain relief solutions.
Will I have to stop taking my current medications?
The trial does not specify if you must stop taking your current medications, but it requires no changes in medications less than 4 weeks before starting and no anticipated need to change psychotropic or pain medications during the 6-week study.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Research has shown that pregnenolone and DHEA are generally safe for humans, but important details require consideration. Pregnenolone, a natural hormone in the body, aids in producing other hormones. It is usually well-tolerated, though limited research exists on its safety specifically for pain management.
For DHEA, studies suggest it is likely safe for short-term use. It has been used safely in doses up to 50 mg daily for up to two years. However, the higher doses used in this trial (up to 400 mg per day) have not been as well-studied, so caution is advised. Some side effects may include changes in hormone levels, which can affect individuals differently.
This trial is in an early stage and aims to learn more about the safety and effectiveness of these treatments for chronic lower back pain. Prospective participants should consult a healthcare provider about the possible risks and benefits.12345Why are researchers excited about this trial's treatments?
Researchers are excited about these treatments because pregnenolone and DHEA offer a fresh approach to tackling lower back pain. Unlike standard treatments like NSAIDs, opioids, or physical therapy, which mainly address symptoms, pregnenolone and DHEA focus on hormonal pathways that might influence pain perception and inflammation. Pregnenolone is a precursor to various hormones, potentially providing a broader impact on pain modulation, while DHEA is known for its role in reducing inflammation and improving mood. These unique mechanisms could offer new hope for those seeking alternatives to conventional pain management strategies.
What evidence suggests that this trial's treatments could be effective for lower back pain?
This trial will compare the effects of Pregnenolone and DHEA on lower back pain. Research has shown that pregnenolone, which participants in this trial may receive, can help reduce chronic low back pain in veterans. Specifically, studies found that those taking pregnenolone reported a significant decrease in pain compared to those taking a placebo. After four weeks, veterans noticed clear relief from their pain symptoms.
In contrast, DHEA (dehydroepiandrosterone), another treatment option in this trial, has shown potential benefits in animal studies, where it helped reduce pain sensitivity. Although limited human data exists on DHEA’s effect on chronic pain, it might help by altering how the body processes pain signals.
In summary, pregnenolone has been effective in reducing chronic pain in people, while DHEA shows promise based on early animal studies.56789Who Is on the Research Team?

Are You a Good Fit for This Trial?
This trial is for US Military Veterans aged 18-65 with chronic low back pain lasting at least 6 months, who have not changed their medications in the last 4 weeks and can commit to not altering them during the study. Participants must use birth control if applicable and cannot be pregnant or breastfeeding. Those with unstable medical conditions, recent substance abuse, or certain psychiatric diagnoses are excluded.Inclusion Criteria

What Are the Treatments Tested in This Trial?
Interventions
- DHEA
- Placebo
- Pregnenolone
Trial Overview
The trial is testing Pregnenolone and DHEA—naturally occurring neurosteroids—against a placebo to see if they safely relieve chronic lower back pain without addiction risks. It's an adaptive Phase II study where participants are randomly assigned to one of these treatments.
How Is the Trial Designed?
3
Treatment groups
Active Control
Placebo Group
Pregnenolone dosing will begin at 500mg/day x 7 days, and will increase by 500mg each following week as tolerated (to a potential maximum dose 2000mg/day).
DHEA dosing will begin at 100mg/day x 7 days, and will increase by 100mg each following week as tolerated (to a potential maximum dose 400mg/day).
Same as active comparator arms, except placebo dispensed
