DRRX receives Breakthrough Therapy Designation (BTD) from FDA. In my opinion this can result in the following:
Expedited development: The FDA will provide more intensive support to DURECT during the development process of larsucosterol for AH. This can help expedite clinical trials, data analysis, and regulatory filings.
Increased chances of approval: Drugs with BTD designation tend to have a higher success rate in obtaining final FDA approval. This can give investors more confidence in the drug's potential for market.
Potential for earlier commercialization: If larsucosterol receives FDA approval, BTD status may allow for an earlier launch date compared to drugs without this designation. This could mean faster revenue generation for DURECT.
Overall, BTD status can significantly improve DURECT's chances of successfully developing and commercializing larsucosterol, potentially leading to increased stock value.

FDA Update & Key Points:
βWe are pleased that the feedback from the U.S. Food and Drug Administration (FDA) supports the advancement of larsucosterol into a single pivotal Phase 3 clinical trial"
"if successful, may serve as the basis for a New Drug Application (NDA) in alcohol-associated hepatitis (AH),β stated James E. Brown, D.V.M., President and CEO of DURECT.
βWe are in the process of designing the registrational Phase 3 trial incorporating the FDAβs comments and insights gained from our Phase 2b AHFIRM trial."
"We expect to provide additional details on our planned Phase 3 protocol and present new analyses from AHFIRM later in the year.β
"During a Type C meeting with the FDA, DURECT received feedback on the recommendations for a Phase 3 clinical trial for larsucosterol in AH that could support a potential NDA filing. DURECT is in the process of designing its planned Phase 3 clinical trial based on the FDA feedback and the results from its completed Phase 2b AHFIRM clinical trial."

DUR-928, also known as larsucosterol, is an investigational drug being developed by DURECT Corporation (DRRX) for the treatment of Alcoholic Hepatitis (AH) and it has received Fast Track designation from the FDA.
How Epigenetics Plays a Role:
DUR-928 is believed to work through epigenetics. Epigenetics refers to changes in gene expression that don't involve alterations in the DNA sequence itself. These changes can influence how cells function.
Here's a simplified explanation of how DUR-928 might work:
In AH, the liver becomes inflamed and damaged due to excessive alcohol consumption. This damage disrupts epigenetic processes, leading to abnormal gene expression and contributing to liver dysfunction. DUR-928 may help restore normal epigenetic patterns in liver cells, promoting healthy gene expression and potentially facilitating liver repair.
Importance of FDA Fast Track Designation:
The FDA Fast Track designation is designed to expedite the development and review of drugs that address serious or life-threatening conditions and have the potential to fill an unmet medical need. DUR-928, has received Fast Track designation from the FDA.
U.S. Market Size: Approx. 150,000 patients are hospitalized annually with AH. Currently there is a very high mortality rate associated with AH (30% at 90 days approx.). It is estimated that DUR-928 if approved may have the potential to generate $1B in annual sales.

Deeper Dive into DUR-928 Hypothetical Scenario and Implications:
Transplant Counts: Let's assume that approximately half the transplants in the study were in patients who would have died without one. Recategorizing these patients as alive would change the results significantly.
Revised Mortality: Factoring those transplants into the 'alive' category would likely lower the observed mortality rates in both the larsucosterol groups and the SOC group, likely resulting in a statistically significant difference between them.
Stronger Endpoint: By recognizing the lifesaving power of transplants, the analysis becomes a better reflection of the overall effectiveness of larsucosterol in improving patient outcomes beyond simply postponing death.
Conclusion: In my opinion even though the results for 90-day mortality didn't quite reach statistical significance, they strongly suggest that larsucosterol has the potential to be a transformative therapy for alcohol-associated hepatitis. Recategorizing transplant patients as alive would likely solidify the statistical significance of the findings. This, coupled with the strong trends observed across other outcomes and the drug's favorable safety profile, presents a compelling case for further investigation and potential approval.

"The topline results from AHFIRM provide compelling evidence that administration of larsucosterol can reduce mortality at 90 days in this devastating disease," said James E. Brown, D.V.M., President and CEO of DURECT. "We have strong rationale to advance larsucosterol into a Phase 3 registration trial designed with adequate power to detect a statistically significant result using 90-day mortality as the primary endpoint. We look forward to meeting with the FDA to discuss next steps. Based on the strength of the clinical data generated to date, if approved, larsucosterol could save many patient lives. We extend our thanks to all the patients, families, clinical trial investigators, and staff across the multiple sites globally who have worked with the DURECT team to bring larsucosterol to this advanced stage."

The two big catalyst for me is: (1). The authorized share count was not increased to 600,000,000 shares, even though DRRX had the votes; that is very, very, interesting. (2) The quarterly filing was was moved up to 7/29/2021. Theses two catalyst, could pertain to a partnership or a buyout news pending. The ship is getting ready to sail, and the rocket is going to the moon. My Opinion!
