Groks take on FDA approval and 1st tranche / cash injection
Thanks for providing more details! Based on your input—"Tranche A: $25.8 MM FDA Approval $0.54 47.9 million"—I’ll interpret this as a hypothetical or real transaction involving Unicycive Therapeutics (UNCY), a biotech company listed on NASDAQ, since it aligns with the context of a publicly traded entity with a stock ticker. Here’s how I’ll break it down:
$25.8 MM (million): This likely refers to a financial tranche, such as funding, a loan, or proceeds from a stock offering.
FDA Approval: Suggests a significant regulatory milestone, possibly tied to one of UNCY’s drug candidates (e.g., UNI-494 or Oxylanthanum Carbonate, based on their known pipeline).
$0.54: This could be the current share price, a proposed offering price, or a price target related to the transaction.
47.9 million: Likely the number of shares outstanding or involved in the transaction (UNCY’s shares outstanding were around 35 million as of mid-2023, per public data, but this could reflect dilution or an updated figure by March 14, 2025).
Since the question focuses on the impact on UNCY’s share price, I’ll assume this describes a scenario where UNCY secures $25.8 million in funding (e.g., via a stock offering or private placement) alongside an FDA approval announcement. Let’s analyze the potential effect:
Key Assumptions
FDA Approval: UNCY’s pipeline includes treatments for kidney diseases, a high-stakes area in biotech. FDA approval (e.g., for Oxylanthanum Carbonate, a phosphate binder) would be a major catalyst, signaling commercialization potential and revenue generation.
$25.8 Million Tranche: This could stem from:
A stock offering (selling new shares at $0.54 each).
A private investment or debt financing.
If it’s a stock offering: $25.8M ÷ $0.54 = ~47.78 million shares, aligning closely with the 47.9 million figure, suggesting a share issuance near that scale.
Current Share Price: I’ll assume $0.54 is the pre-transaction price (close to UNCY’s historical trading range in 2023–2024, though I lack real-time data for March 2025).
Shares Outstanding: If 47.9 million is the post-transaction total, it implies significant dilution from a prior base (e.g., 35 million shares + 12.9 million new shares = 47.9 million).
Impact on Share Price
The share price effect depends on two opposing forces: positive catalyst (FDA approval) vs. dilution (new shares).
Positive Impact from FDA Approval:
FDA approval is a game-changer for small-cap biotechs like UNCY. It de-risks the company, boosts investor confidence, and often triggers a sharp price increase.
Historical examples: Small biotechs can see 50%–200%+ spikes post-approval (e.g., Cassava Sciences jumped ~100% on Phase 2 data in 2021). For UNCY, a $0.54 base could rise to $0.81–$1.08 (50%–100% gain) purely on approval news, assuming no dilution.
Negative Impact from Dilution:
If $25.8 million comes from issuing ~12.9 million new shares at $0.54, it increases shares outstanding by ~37% (from 35 million to 47.9 million).
Dilution typically depresses share price as earnings per share (EPS) and ownership stakes shrink. Without the FDA boost, a 37% dilution might drop the price proportionally (e.g., $0.54 × 0.63 = ~$0.34), though market dynamics soften this in practice.
Net Effect:
The FDA approval’s positive momentum likely outweighs dilution’s downward pressure, especially for a small-cap biotech with a low market cap (~$20M at $0.54 and 35M shares).
Scenario 1: Strong Approval Reaction: If the market values the approval highly (e.g., doubling market cap to $40M–$50M), the post-dilution price could rise to $0.83–$1.04 ($40M–$50M ÷ 47.9M shares), a 54%–93% increase from $0.54.
Scenario 2: Mild Reaction: If approval excitement is tempered by dilution concerns, the price might stabilize near $0.60–$0.70, a 11%–30% gain.
Scenario 3: Overshadowed by Dilution: If the market fixates on dilution (unlikely with FDA approval), the price could dip below $0.54 temporarily, though this is rare with a major catalyst.
Market Sentiment and Timing:
Biotech stocks are volatile. On March 14, 2025, broader market conditions (e.g., interest rates, sector trends) could amplify or mute the reaction.
Trading volume would surge, potentially exaggerating short-term swings.
Conclusion
This transaction—$25.8 million raised with an FDA approval—would likely increase UNCY’s share price from $0.54, assuming the approval’s positive impact overshadows dilution. A plausible range is $0.60–$1.04 (11%–93% gain), with the higher end reflecting strong market enthusiasm for the approval. The exact outcome hinges on:
The drug’s market potential (e.g., blockbuster vs. niche).
Investor perception of the $25.8M use (e.g., funding commercialization vs. just cash burn).
Whether 47.9 million is indeed the new share count.

Cosa. U have to look at the entire package they submitted to get FDA approval
The two trials likely submitted as the core clinical evidence from healthy volunteers are the Phase 1 dose-ranging study and the bioequivalence study.
These, combined with the later pivotal trial and preclinical/CMC data, comprise the full NDA package accepted by the FDA on November 11, 2024, with a PDUFA target action date of June 28, 2025.
The last trial with dialysis patients , requested by the FDA ...added the additional safety and efficacy info they requested .
The FDA approval path they are on is different then the path for Xphozah as OLC is a reformulation of an existing FDA drug and therefore has about a 70-80% chance of being approved ( based on history of similar applicants )
A wash out is where they take the patients of their existing serum pho lowering drugs .....often 4-6 wks for many drugs ...so they can get a baseline ( no drugs in the system )
Then add the new drug and test ...I'd have to look at the data ...but typically 90 days later

OLC’s NDA, filed under the 505(b)(2) pathway, was accepted by the FDA in November 2024, with a PDUFA target action date of June 28, 2025. The 505(b)(2) route itself is a good sign—it’s a well-trodden path for drugs building on existing approvals (here, Fosrenol), and historically, it has a higher approval rate than full 505(b)(1) NDAs. General FDA stats suggest 505(b)(2) applications hover around a 70-80% approval rate, compared to 50-60% for novel drugs, though this varies by therapeutic area and data quality.
The data package looks solid so far. Unicycive’s pivotal trial (results out June 2024) showed OLC was well-tolerated, with a 6% discontinuation rate due to adverse events—lower than Fosrenol’s 14%—and over 90% of patients hit target phosphate levels (≤5.5 mg/dL) post-titration. The Phase 1 dose-escalation study (published January 2025) confirmed safety across escalating doses, and the bioequivalence study (published December 2024) nailed pharmacodynamic equivalence to Fosrenol. These check key boxes: safety, tolerability, and a link to an approved drug’s efficacy profile.
The FDA’s agreement on the trial design (60 patients, no statistical efficacy analysis needed) and the PDUFA fee waiver ($4 million saved) further signal alignment and confidence.

Re trial for efficacy
Unicycive Therapeutics conducted a pivotal clinical trial to evaluate the efficacy of Oxylanthanum Carbonate (OLC) for the treatment of hyperphosphatemia in chronic kidney disease patients on dialysis.
The trial, known as the UNI-OLC-201 pivotal clinical trial, was designed to assess both the safety and efficacy of OLC.
Positive top-line results from this trial were reported on June 25, 2024, indicating that OLC performed well in reducing serum phosphate levels.
Additionally, initial patient satisfaction findings from this trial were announced on July 9, 2024, showing high patient preference and satisfaction with OLC compared to prior phosphate binder therapies. This trial is part of Unicycive's efforts to seek FDA approval for OLC via the 505(b)(2) regulatory pathway.
Agree that its likely they do a reverse split

FYI from Grok.
If no Adcom, its assumed OLC will be approved by June 28
Based on the latest available information, Unicycive announced on November 11, 2024, that the FDA accepted its New Drug Application (NDA) for OLC, with a PDUFA target action date of June 28, 2025. However, there was no mention of an AdCom meeting in that announcement.
Typically, the FDA schedules AdCom meetings closer to the PDUFA date if they deem it necessary, often within 2-3 months prior, but no specific scheduling is guaranteed unless announced.
As of today, March 05, 2025, a quick review of the FDA’s Advisory Committee Calendar and recent Unicycive press releases does not indicate a scheduled AdCom for OLC.
The FDA’s calendar currently lists meetings up to early 2025, but nothing specific to Unicycive or OLC appears.
Given the PDUFA date is still over three months away, it’s possible an AdCom could be announced later, potentially in April or May 2025, if the FDA requires expert input on OLC’s NDA.

From Grok ...OLC and Fosrenol
Whats the difference between Unicycives OLC and Fosrenol
Unicycive’s Oxylanthanum Carbonate (OLC) and Fosrenol (lanthanum carbonate) are both phosphate binders used to treat hyperphosphatemia, a condition common in chronic kidney disease patients on dialysis where phosphorus levels in the blood become too high. While they share similarities, there are key differences that set them apart, particularly in design and patient experience.
Both medications work by binding dietary phosphate in the gut to prevent its absorption into the bloodstream. OLC is a next-generation lanthanum-based binder developed by Unicycive Therapeutics, leveraging proprietary nanoparticle technology, while Fosrenol, developed by Shire (now part of Takeda), is an established lanthanum carbonate formulation. Clinical studies have shown that OLC is pharmacodynamically bioequivalent to Fosrenol, meaning they achieve similar phosphate-lowering effects in the body.
The primary difference lies in pill burden and administration. OLC aims to reduce the number and size of pills patients need to take. In a pivotal trial, patients switching to OLC saw their median daily pill count drop from 6 to 3, cutting the burden in half compared to prior therapies, including Fosrenol. Fosrenol typically requires multiple large chewable tablets per day—often 3 or more, depending on the dose (500 mg to 1000 mg three times daily)—which can be cumbersome. OLC, by contrast, is designed to be swallowed, not chewed, which patients have reported as easier and more convenient. In a satisfaction survey from the same trial, 98% of patients found OLC easy to take, compared to only 55% for their previous binders, and 79% preferred OLC over prior treatments.
Effectiveness-wise, they’re on par due to bioequivalence, but OLC’s formulation may offer practical advantages. Studies suggest OLC has a high phosphate-binding capacity with a lower medication volume, meaning it can bind more phosphate per dose than Fosrenol and other binders. Safety profiles are similar, with both showing mild-to-moderate side effects like diarrhea and vomiting, though OLC’s trial data reported low discontinuation rates (1.4% in the evaluable group), indicating good tolerability.
Unicycive is positioning OLC as a potential best-in-class option, addressing the unmet need for better compliance highlighted by nephrologists. Fosrenol, while effective and widely used, hasn’t evolved much since its approval, and its chewable nature and higher pill count can deter adherence. OLC’s development, currently under FDA review with a decision expected by June 2025, reflects an attempt to refine what Fosrenol started, prioritizing patient-friendly dosing without sacrificing efficacy.
In short, OLC and Fosrenol do the same job biologically, but OLC is engineered to be simpler to take—fewer, smaller, swallowable pills—potentially making life easier for dialysis patients. Whether that translates to real-world superiority depends on individual patient needs and how OLC performs post-approval, assuming it gets the green light.

Cosa good to see U posting again .
OLC is a "refined / distilled " version of Fosrenol ...a drug my wife prescribes to her dialysis patients that can't tolerate the generic pho binders ..Renvela etc .
Because it's essentially a " distilled " version of an existing FDA approved drug ...it didn't need to go thru the phase 1 / 2 process ....instead a test to make sure it was the bioequilant of Fosrenol ( which it passed ) and then a trial with dialysis patients ...which was also successful .
The trial with dialysis patients was to test serum pho lowering ...but also adverse events ...was it more tolerable etc .
Fosrenol is one of the most effective drugs for lowering serum pho ...however many complain of nausea.
With OLC they apparently added an extra O2 molecule which has reduced the incidence of nausea .
( update .... wrong ...its an oxygenated version )
Just going from memory here but you might do a search / ChatGPT / Perplexity on the difference between Fosrenol and OLC.
ARDX's Xphozah is a different issue . The issues around its initial approval were over its high rate of diarrhea and low rate ( compared to Fosrenol /OLC ) of lowering serum pho.
HOWEVER ...once approved some of my wife's patients have adjusted to XPHOZAH and its been the only drug to have worked to lowering these particular patients serum pho to goal levels .
Now without Medicare coverage there are some work around some of these patients may attempt to...noted in previous posts .
Bottom line ....the feedback I get is that Nephrologists want to try OLC as soon as possible .
1) its very effective at lowering serum pho
2) OLC is a small pill that can be swallowed ...and therefore increase patient compliance . They hate chewing the existing binders or the size and number they need to take
3) Its 1/3rd of the cost of XPHOZAH and should be available to Medicare patients since they have agreed to enter the TDAPA process .
My only concern is if the PDUFA date gets extended due to FDA cut backs

PS from Perplexity
Fosrenol (lanthanum carbonate) and OLC (oxylanthanum carbonate) are both phosphate-binding agents used to treat hyperphosphatemia in patients with chronic kidney disease. However, there are some key differences between the two:
Formulation: OLC is a next-generation lanthanum-based phosphate binding agent that utilizes proprietary nanoparticle technology24.
Administration: Fosrenol tablets are chewed, while OLC tablets are smaller in size and swallowed whole with water3. This difference in administration may lead to better patient compliance with OLC.
Pill burden: OLC requires a lower pill burden for patients in terms of number and size of pills per dose compared to currently available treatment options24.
Development stage: Fosrenol is an FDA-approved medication, while OLC is still an investigational drug undergoing the FDA's 505(b)(2) regulatory pathway38.
Tolerability: In a recent study, OLC showed a lower discontinuation rate due to adverse events (6%) compared to Fosrenol's reported rate of 14%23.
If approved, OLC is expected to share substantially the same product label and prescribing information as Fosrenol, with the exception of the administration method35.
The potential advantages of OLC, such as lower pill burden and easier administration, may lead to improved patient adherence in the treatment of hyperphosphatemia.
And ...no extra O 2 molecule ...but
The "Oxy" in Oxylanthanum Carbonate does not indicate an additional oxygen molecule, but rather refers to the oxygenated form of lanthanum carbonate.

Kiwi, since you have been discussing potential timeline for OLC approval, I was wondering what your thoughts were about the following. I am in another stock, AVXL, Anavex Life Sciences, where on their iHub board they have been actively discussing the firings and layoffs at the FDA and how that would impact drug approvals going forward (obviously mostly delaying their approval). They actually have an application for approval with the EMA and not yet with the FDA from what I understand, but I was reading the discussion about workforce reduction at the FDA and wondering how it might impact other companies, like UNCY, RZLT, etc?

Assuming OLC is approved by end of June and immediately enters the TDAPA process
This is how they determine what CMS will pay
The Centers for Medicare & Medicaid Services (CMS) determines the Transitional Drug Add-on Payment Adjustment (TDAPA) pricing for new dialysis drugs based on specific methodologies tied to the drug's pricing data and regulatory criteria. Here is an overview of how CMS establishes TDAPA pricing:
Pricing Basis:
For most drugs, TDAPA payments are set at 100% of the drug’s Average Sales Price (ASP). If ASP is not available, CMS uses the Wholesale Acquisition Cost (WAC). If neither ASP nor WAC is available, the payment is based on the manufacturer's invoice price156.
In some cases, CMS may adjust this formula. For example, calcimimetics were initially reimbursed at ASP + 6%, but this was later reduced to ASP + 0%17.
Eligibility and Duration:
TDAPA applies to new renal dialysis drugs and biological products for at least two years, during which CMS collects utilization and cost data to determine whether adjustments to the ESRD Prospective Payment System (PPS) base rate are necessary15.
Special Adjustments:
For certain categories, such as phosphate binders, CMS has considered additional fixed payments or percentage increases to account for operational costs or acquisition price variations37.
A fixed increase of $36.41 per monthly claim is currently applied for phosphate binders under TDAPA3.
Post-TDAPA Adjustments:
After the TDAPA period ends, CMS may implement a post-TDAPA payment adjustment based on 65% of the estimated expenditure levels from the prior year to ensure continued access to innovative therapies24.
This structured approach ensures that new therapies are temporarily reimbursed outside the bundled payment system while CMS gathers sufficient data to incorporate them into the ESRD PPS framework.
So OLC is expected to cost $1,300 a mth IIRC and CMS will cover all of that for at least the first 2 yrs ....and 65% of that in the following years .
ARDX's XPHOZAH is not currently in the TDAPA process so is receiving nothing from CMS for their Medicare dialysis patients
My take anyway ...feel free to critique

UNCY is supposed to have a commercialization plan presented this Qt .
The Co needs to ramp up but and be ready to roll as soon as OLC is approved . The time line for the TDAPA process ...which is CMS payments beginning is at best 3 mths from approval .
Some recent examples
For VAFSEO® (vadadustat), approved in October 2024, TDAPA payments began on January 1, 2025, about three months later1.
For DEFENCATH® (taurolidine and heparin), approved in April 2024, payments started on July 1, 2024, also about three months later1.
In general, the TDAPA process starts within a few months after a drug's approval, contingent on completing the HCPCS code application and CMS's review timeline.
They really need to max sales in the first 2 yrs of TDAPA ...as CMS payments will decline after that and exclusivity runs out in 2031

So the previous post was about the challenges dialysis patients have with the current phosphate binders.
The question is ...Is OLC more tolerable ( fewer side effects ) than Lanthanum Carbonate ( Fosrenol )
Based on the available data, OLC (oxylanthanum carbonate) appears to be more tolerable than traditional lanthanum carbonate.
The pivotal clinical trial for OLC demonstrated a low rate of discontinuation due to adverse events, with only 5/86 patients (6%) discontinuing from the study1. This compares favorably to the 14% discontinuation rate due to adverse events reported for Fosrenol (lanthanum carbonate) in its FDA-approved Package Insert1.
In the OLC-201 trial, there was only 1 discontinuation due to a treatment-related adverse event in the Evaluable Population (n=71), a rate of 1.4%1. In the full Safety Population, a total of 3 patients discontinued due to treatment-related adverse events, a rate of 3.5%1.
OLC was also well-tolerated in a dose-escalation study with healthy participants. There were no serious adverse events, severe or life-threatening adverse events, deaths, or adverse events leading to discontinuation710.
The most common side effects of OLC were similar to those of lanthanum carbonate, including diarrhea (9%) and vomiting (6%)4. However, the overall safety profile of OLC appears to compare favorably to Fosrenol and other phosphate binders on the market4.
So the issue is ..can UNCY mgt get this FDA approved without having to do a reverse split or raise funds first
They have funds once approved thru the exercising of warrants .

Why is this stock so cheap ? What am I missing here ?
I agree with Mr Mister that the stocks been depressed lately as preferred shares at low conversion prices get converted to common when the stock trades higher ....and that may cap advances , but consider the following
Strong XPHOZAH® (tenapanor) performance continues, recording approximately $161 million net product sales revenue during 2024
XPHOZAH demonstrated an exceptional launch and finished its first full year of commercialization with 2024 U.S. net product sales revenue of approximately $161 million, including approximately $57 million in net product sales during the fourth quarter, subject to adjustment in connection with preparation of audited financial statements.
ARDX's XPHOZAH was able to generate $161m net product rev in 2024 , $57 m of that in the last Qt . How long has XPHOZAH been on the market ?
As new Oral binders go XPHOZAH is expensive , around $3,300 a mth where as OLC is expected to be around $1,200 a mth...... so insurers are likely to want patients to try the new lower cost pho binders first especially since many consider OLC to be more effective at lowering serum pho .
UNCY ...market cap of $64 m , Enterprise value of only $36 m ....for a drug that should do just as well as, if not better then what ARDX generated in XPHOZAH net rev ....$161m...in 2024 .
Yes preferred converting to common and exercising the warrants will significantly dilute the stock ( exercising warrants provides cash to the Co to market drug etc ...in exchange for new stock ) .... but given size of market and need for a better pho lowering drug ....price of stock seems cheap .
What am I not seeing here ....anyone ? Patent issue ? Believe they have new drug exclusivity for 13 yrs ???
Maybe it's the amount of warrants that will eventually be exercised ( converted to stock ) .....but the Co would raise $ anyway when / if they get FDA approval June 28 th to hire sales reps etc ...unless they sell the Co
