Thanks, Melissa. Good morning, everyone, and welcome to the Heron Therapeutics' First Quarter 2024 Earnings Call. Today, we are pleased to update you on our latest achievements in Q1, including financial performance, progression on our development projects, CrossLink progression and a general corporate update.
We started the quarter off with tremendous momentum. First, we signed the CrossLink agreement on January 7 and shortly after, on January 23, we received official approval of our expanded indication of ZYNRELEF, which broadens our label into spine, shoulder and other soft tissue surgical procedures. [indiscernible] these 2 events, we had a National Sales Meeting where we trained all of our sales folks on the new indications. We also developed an internal group to lead the training process of the CrossLink team.
We have continued to improve our financial efficiency by reducing spend and improving margins. We believe, with this continued approach, we will achieve profitability, as predicted, by Q4 of 2024.
Before we move on to product performance, I did want to show this slide to highlight what has been achieved this quarter versus just 12 months ago. As you can see, in Q1 of 2023, we had net revenues of $29.6 million, COGS of $16.8 million with an overall loss of just over $33 million. In the same time period in 2024, we had $34.6 million in net revenues, $8.4 million in COGS and a loss of $4.8 million, which is a $28.2 million positive swing in just 12 months, along with a gross margin improvement from 43% to 76%. The takeaway from this is we are on the right path and we have the business well-positioned for the future.
Now, moving on to product performance, the Oncology franchise continues to outpace our expectations with CINVANTI net revenues of $25.6 million for the quarter and SUSTOL net revenues of $3.6 million for the quarter. We continue to maintain our existing market share in a very competitive environment with the oncology franchise, and we believe these products will continue to show a safe consistency throughout 2024.
Total Acute Care net revenues for the quarter were $5.5 million, which represents a 45% increase from $3.8 million in the first quarter of 2023. ZYNRELEF net revenues for the quarter was $5 million, which represented the second straight quarter with revenues of $5 million or greater. APONVIE net revenues for the quarter continued to increase quarter-on-quarter and year-on-year to $500,000 for the quarter ended March 31, 2024.
While we are pleased with the direction we are headed, we knew Q1 was going to be relatively flat when considering seasonality and with all the other activities we had going on during the quarter such as label expansion training and with the kickoff of CrossLink.
I will speak to ZYNRELEF's performance specifically in a moment when I give an update on CrossLink, but I did want to mention we are seeing tremendous uptake with APONVIE. Our sales message is really beginning to resonate with many institutions around the country, and this will ultimately trickle down to impact net revenue growth. In Q3 of 2023, our new management team realized that our sales message for APONVIE needed to be focused around the issue of PONV versus just trying to convert oral premising and the impact it can have financially in the perioperative space. We retrained our reps, refined our sales message and improved our incentive comp plan to focus around this messaging. Since implementation in October of 2023, we have had over 70 P&T wins and, as you can see from the slide, another 35 this quarter as well. Once approved by P&T, there is a bit of lag time before the sales bolus begins to take place. But as these accounts come on board, we're going to see a continued growth in sales as APONVIE generally bills system-wide in most accounts. We are very pleased with the APONVIE momentum, and it should only improve. As we continue to bring more CrossLink reps on board, this will free up more time for our Heron to actually sell APONVIE and ZYNRELEF versus actually being present in the OR during case management for ZYNRELEF preparation.
Now, moving on to the CrossLink update, training for the CrossLink team kicked off with the executive team in late February and with the reps at the beginning of March. We now have 216 CrossLink reps [indiscernible] joint, trauma and spine that have been fully trained and are out in the field selling ZYNRELEF. While the fruits of the CrossLink partnership are not apparent in Q1, we believe that the timing of the initiation of the partnership and the training, [ as been staged ] and is still ongoing, will pay many dividends as more and more field reps come online. Our plan is to continue to expand our reach across the country with over 650 reps being fully trained and integrated before the launch of the VAN in Q4 of this year.
Internally, we have been amazed by the relationships the CrossLink team has in the orthopedic surgical community, and we realize, in time, this is going to have a substantial impact on ZYNRELEF revenues. In just 1 month of their joint team being trained and promoting ZYNRELEF, we already had more than 20 new orthopedic surgeons use our product in the first month. This is just in North Carolina, South Carolina, and Georgia, which represents the inaugural region for our partnership with CrossLink. We have seen a 12-fold increase in unit sales growth within these 3 states versus the rest of the country. We have had around 60 introductions and touchpoints to new ortho users in the month of April alone, and we anticipate 40 new users to come on within the next 30 days. We are literally just getting started and building the car while we are driving, but the impact that CrossLink will have is very clear and will continue to play out as we get more reps trained and integrated into the partnership.
I will now turn the call over to Bill Forbes, our Chief Development Officer. Go ahead, Bill.
