David Gonyer

Thank you, Daniel. Thanks everyone for joining us today.

I'll start by outlining the important progress Evoke both made in 2022 in meeting key strategic goals. I'll also review key events and metrics in the fourth quarter of 2022 and thus far in 2023. I'll then turn the call over to Chris and Matt, who will discuss commercial operations and financials.

As I mentioned in today's release, Evoke's fiscal year 2022 was a period of significant growth and progress on several key fronts. Year-over-year revenues, new GIMOTI prescribers, prescription fills and patient enrollments all showed substantial improvements in 2022 compared to 2021.

Looking back, in 2021, we focused our attention to GIMOTI's value proposition in the marketplace. There was and is a clear unmet need in the market for a non-oral treatment for symptoms associated to diabetic gastroparesis; which for those who are new to the story, is the stomach paralysis caused by the nerve damage that can result from uncontrolled high blood sugars. In such cases, the stomach doesn't empty properly and food and medications may take a long time to leave the stomach and move into the intestines where they need to be to be absorbed.

Far too many of the approximately 2 million to 3 million patients being treated with traditional oral therapeutics for this debilitating disease end up in the ER or take more invasive steps to address their symptoms; of which oral medication simply don't help improve or could have even made symptoms worse. These symptoms can include nausea, vomiting, bloating, abdominal pain and are often accompanied by dehydration, malnutrition and erratic blood sugars.

GIMOTI is our nasal spray formulation of metoclopramide proven to be an effective medication for treating diabetic gastroparesis. GIMOTI is the only FDA approved non-oral outpatient therapy for gastroparesis and received FDA approval in June of 2020, and then entered the market in the fourth quarter of 2020.

After establishing GIMOTI's viability in the marketplace in 2021 by addressing unmet need, in 2022, we focused on the following:

First, increasing the awareness of and accessing -- access to GIMOTI as a groundbreaking new treatment for diabetic gastroparesis among patients and their healthcare providers, or HCPs, and those are primarily gastroenterologists. And we did this through: face-to-face educational interactions with HCPs by our commercial partner, EVERSANA, and the sales team; building channel partnerships in conjunction with EVERSANA to improve access to GIMOTI, these include vitaCare, our pharmacy partner, wholly-owned by GoodRx, and also UpScriptHealth, a consumer telehealth platform; and increasing state Medicaid coverage for GIMOTI.

Second, we succeeded in making progress toward our ultimate objective of having GIMOTI become the standard of care for treating diabetic gastroparesis by presenting compelling real-world data at leading medical and scientific forums.

And finally, in 2022, we focused on fortifying and enhancing our intellectual property estate to deter potential generic competitors ensure that GIMOTI is the only such product available in the market for as long as possible. And Chris will provide more detail on these areas by expanding on some specific milestones.

Until GIMOTI, there has been nothing new to treat gastroparesis in over 40 years since the approval of oral metoclopramide and no pharmaceutical company voiced in the marketplace. The immense challenge that we have undertaken in upending medical consensus that has been in place more than four decades simply does not happen overnight.

Happily though, we're making impressive progress in convincing the diabetic gastroparesis treatment community that GIMOTI's nasal spray metoclopramide formulation is an important and needed treatment for patients instead of current oral tablet options. To that point, GIMOTI was added to the new gastroparesis guidelines by the American College of Gastroenterology as recommended first-line therapy. This is a very important milestone for GIMOTI and Evoke.

In September of last year, we announced that GIMOTI was nominated for Healio's annual Disruptive Innovators Awards under their Industry Breakthrough category. GIMOTI was selected among other novel gastroenterology products from major pharmaceutical companies. Healio is an online source for in-depth specialty clinical information and offers a wide industry accepted news. The Disruptive Innovators Award hosted by Healio is an annual event to honor the trailblazers, movers and industry personnel that are creating a difference in the field of gastroenterology. And as a nominee for the award, GIMOTI was recognized for its role in changing the face of gastroenterology and shifting the status quo towards a betterment of the field.

In May 2022, Evoke participated at DDW, or Digestive Disease Week, which is the largest global conference for gastroenterology. And we were pleased to present a poster of distinction to the scientific and clinical experts and key opinion leaders from around the world. The study provided real-world statistics using the largest claims database available, which covers over 80 million lives in the U.S. to assess the incidence of tardive dyskinesia, or TD, for patients taking metoclopramide over a 10-year period.

Results for patients that had received metoclopramide demonstrated a lower risk of developing TD than stated in previously reported studies. The data revealed an incidence of TD among gastroparesis treated patients -- gastroparesis patients treated with metoclopramide of just 0.1%. The poster data supports the safety profile of metoclopramide. And the aim of the study was to update the medical literature with current information about the incidence of TD in patients with and without gastroparesis and those taking metoclopramide.

By supporting the largest ever real-world study on the important issue -- this important issue, we hope to help HCPs and organizations understand of incidence of TD, recognize patients who might be at high risk and revisit the benefit versus the risk of this important compound in patients with gastroparesis.

In addition to the new ACG guidelines in GIMOTI's first-line recommendations, two recent announcements also reveal how we're chipping away at the medical consensus I mentioned earlier.

In January of this year, we announced that another of our studies will be presented as an abstract at the Academy of Managed Care Pharmacy, or AMCP, annual meeting taking place this week in San Antonio. The abstract entitled " Real-World Healthcare Resource Utilization of Patients Treated with Metoclopramide Nasal for Diabetic Gastroparesis" is a study of nearly 300 patients using GIMOTI that revealed a reduced need to visit the ER or take more invasive steps to treat their condition. These results have been extremely well received with key opinion leaders.

Last month, together with EVERSANA, we reported that yet another abstract was not only accepted but selected for the plenary lecture presentation at the upcoming Digestive Disease Week in Chicago from May 6 to May 9. This abstract entitled "Reducing Real-World Healthcare Resource Utilization for Patients with Diabetic Gastroparesis Treated with Metoclopramide Nasal Spray Versus Oral Metoclopramide" provides compelling healthcare resource utilization data on the effectiveness of GIMOTI as a potentially needle moving solution in the treatment of gastroparesis.

For the remainder of 2023 and beyond, we'll continue our strategy of highlighting the benefits of GIMOTI at important medical meetings and continue to generate new data.

Next, as I referred to earlier, fortifying and enhancing Evoke's intellectual property estate is a vital component of our strategy to make GIMOTI brand synonymous with the new treatment paradigm for diabetic gastroparesis. A prime example is the recent successful litigation against generic pharma giant Teva Pharmaceuticals.

Last year, we received a Paragraph IV certification notice letter from Teva. This notice indicated that Teva had submitted an abbreviated new drug application, or ANDA, to FDA seeking approval to manufacture and sell a generic version of GIMOTI prior to the expiration of certain Orange Book-listed patents protecting GIMOTI. We initiated a patent infringement lawsuit against Teva and vigorously defended our intellectual property rights protecting the product. And as a result, Teva withdrew its Paragraph IV for its generic ANDA and will not pursue approval until GIMOTI's last Orange Book-listed patent expires. And this is currently 2030, but may be extended pending other filed patents.

In addition, no further ANDA filer will be eligible to receive 180-day generic exclusivity for an ANDA that references GIMOTI. This first to file regulatory path is typically a highly sought after by generic firms. Consequently, this matter has ended and we believe the successful outcome reflects the strength of our intellectual property. And furthermore, this strengthens our resolve to defend our rights, particularly against larger well-resourced companies.

During 2022, we also bolstered GIMOTI's intellectual property estate with key milestones, I'll briefly summarize. In December, USPTO issued Evoke a patent under the title "Treatment of Moderate and Severe Gastroparesis." This patent expires in 2038 and covers the methods for treating moderate to severe gastroparesis with metoclopramide via the intranasal route of administration. The grant of this patent confirms that we -- what we observed in our Phase II trial results from utilizing nasal metoclopramide to treat patients suffering from moderate to severe gastroparesis.

In November, the USPTO issued a notice of allowance for a patent application entitled "Nasal Formulations of Metoclopramide," which would expire in December 2029. This patent application is a continuation of several other U.S. patents filed by the company over the last decade. And in July, the Canadian intellectual property office granted Evoke a key patent for our previously submitted application entitled "Nasal Formulations of Metoclopramide." This patent corresponds to the two other FDA Orange Book-listed patents under the same title that expire in 2029 and 2030. The patent covers the methods of use of nasal delivery of metoclopramide for treating diabetic gastroparesis. This Canadian patent expires in 2029 and provides patent protection in another potential market for our novel gastroparesis treatment.

We're pleased with the progress we made in 2022 and thus far in 2023 to further establish our proprietary concept of delivering effective medication through the naval pathway to treat symptoms associated with diabetic gastroparesis. We are eager to further our goal to capitalize on this large and growing market opportunity in the U.S. and abroad. Our intellectual property portfolio now includes FDA Orange Book-listed patents and other patents in the EU, Japan, Canada and Mexico.

Now, before turning the call over to Chris, I want to provide a little color on the fourth quarter 2022 financial and operating results. And Matt will take us through key components of our financials for the quarter and the year as well.

As mentioned in today's press release, the fourth quarter saw slight $36,000 decrease in our net product sales in the third quarter, even though we had an 8% increase in GIMOTI prescription fills. The reason for this decline after three quarters of sequential revenue growth in 2022 is straightforward: first, Q4 has more holidays and fewer working days than Q3; those holidays coincide with the end of the month, which tend to be our stronger weeks; and there were also pharmacy closures due to weather events during that time; and lastly, we experienced a slightly higher number of prescriptions provided to uninsured or underinsured patients. In such circumstances, it's Evoke's practice to offer GIMOTI at a discount to those patients in urgent need of gastroparesis symptom relief. And we expect to return to positive sequential revenue growth in 2023 as the sales mix returns to levels we saw in the first three quarters of 2022.

Finally, the number of cumulative GIMOTI prescribers increased by approximately 25% to 1,017 HCPs at December 31, 2022 from 812 through December 31, 2021. This metric continues to increase, reaching 205 prescribers at the end of January of this year, the highest month on record.

And finally, as I mentioned, prescription fills in the fourth quarter of 2022 increased by 8% compared to the previous quarter. Prescription fills for all of 2022 increased by 178% compared to 2021.

With that, I'll turn the call over to Chris. Chris?

Chris Quesenberry

Thank you, Dave.

2022 was a year of tremendous progress for Evoke, GIMOTI and EVERSANA. I'd like to add my support to what Dave described as last year's significant progress in physician awareness and patient access to GIMOTI as a needed solution for relief of diabetic gastroparesis symptoms.

Our Evoke team was in EVERSANA and in the field as well as our partners at vitaCare and UpScriptHealth continues to execute on our strategy to make GIMOTI the standard of care for patients suffering with diabetic gastroparesis and to improve access to GIMOTI for appropriate patients. There's not been without challenges at many turns, yet our team remains focused and is steadfast to alter the clinical inertia and a habit that has been status quo in this market, patients deserve better. Broadening and deepening healthcare practitioner trial and adoption of GIMOTI was and will continue to remain our priority focus and we have made steady progress.

Q4, by many metrics, was our best ever. We nearly doubled our new prescribers in 2022, growing 96%. In the fourth quarter alone, we increased new prescribers 43% over Q3. And our total cumulative new prescribers continued to expand to 1,017. Repeat prescribers grew 774% in 2022 versus '21, and in Q4, we expanded our Q3 total by 14%. As prescribers grew, so did dispenses, at 8% improvement over Q3. Full year dispense growth was 178% versus 2021. [And you'd] (ph) see excellent continuation by our patients with a 79% refill rate for those that have scripts remaining on their treatment. Lastly, refills for GIMOTI is a metric we are closely watching. Refills grew 34% in Q4 compared to Q3 and 219% year-over-year.

The primary driver of performance in Q4 and in 2022 was interactions with healthcare providers. Face-to-face interactions in the post-COVID era continues to be the most important lever. We see a pattern emerging where when a healthcare provider in a practice prescribes GIMOTI and has a positive experience, they tend to prescribe more, and those that are in the practice with them begin to adopt GIMOTI as well. It is evidence that our total practice approach is paying dividends.

In addition, we conducted peer-to-peer educational programs last year. Those programs reached 673 total attendees where the rationale and benefits of GIMOTI were discussed, including relevant patient case experience. These programs increased the knowledge of our audience and we saw significant impact on prescribing, increasing 44% from prior to attending a program. We plan to double our programming this year to reach a broader audience.

To further combat status quo thinking, we leveraged the publication of the updated ACG guidelines for gastroparesis by producing our own summary of the guidelines and highlighting the position of GIMOTI and oral metoclopramide as first-line pharmacotherapy. This has generated significant conversations and added credibility to our message.

We also continue to conduct patient market research to track their awareness, trial and utilization patterns. Our last wave confirms feedback we were hearing from providers and demonstrated that roughly 50% of users do not see any symptom improvement from existing oral treatment options, whether they're liquid or tablet forms. 38% of respondents discontinued their gastroparesis medications primarily due to either side effects or a lack of symptom improvement. Of those respondents who were aware of GIMOTI prior to the survey, 43% are current users and 100% of those current GIMOTI users reported seeing at least some symptom improvement with diminished nausea being the most cited symptom improvement. Finally, patients rated GIMOTI as more favorable than competing treatments on all attributes treats related to tolerability and efficacy compared to other treatments.

We are encouraged by these results and yet we recognize there is still a significant gap in conversations between patients and providers around whether current therapies are working, what alternative treatments are available, and how these treatments differ.

Another contributor to success in 2022 was changing our distribution approach. May of last year, after a four-month pilot, we switched distribution to vitaCare prescription services. The switch to vitaCare significantly improved prescribing of GIMOTI, allowing HCPs to e-prescribe GIMOTI directly. Additionally, we saw the time from the submission of prescription to the delivery of GIMOTI to a patient's home, what we call speed to therapy, improve.

Reliable access to GIMOTI, especially with a low out-of-pocket expense for patients, is a primary driver for their initial and ongoing use. When patients get access to GIMOTI, we see and hear positive feedback. With the vitaCare process, our refill rates have continued to improve and is at 79%, the highest we've seen since launch.

Another opportunity for GIMOTI is coverage by insurance plan. We continue to build on our success and access with 110 payers approving at least one Rx since launch. In Q4, 69% of dispensers were covered by either a commercial or government insurance, and that is relatively stable from prior quarters.

We are committed to expanding access to GIMOTI. Part of that commitment comes in continuing to build on the value proposition for GIMOTI and to demonstrate further evidence. Dave outlined two important new studies that we have recently submitted to medical congresses, which have both been accepted. These studies leverage our exclusive pharmacy data for GIMOTI patients and link it compliantly to claims database, which allows us to understand the utilization of healthcare resources, such as physician office visits, hospital outpatient visits, hospital inpatient visits and emergency room visits. These were real-world data complement clinical trial data, which affirm the safety and efficacy of a product in a controlled setting and go beyond that to examine the impact of treatment on various stakeholders like providers, patients and payers, varied clinical and diverse demographic settings.

Now, prior to commenting on the new studies, the previous tardive dyskinesia study we conducted, which was presented at last year's Digestive Disease Week, remains an important clinical update for physicians to be aware of with the use of metoclopramide. Whereas various prior small studies published decades ago, noticed an incidence rate of 10% or higher with TD for metoclopramide. This groundbreaking analysis examining claims data across 80 million patients in the U.S. showed a much lower incidence at 0.1% of all gastroparesis patients taking metoclopramide over the 10-year survey.

These data have received significant attention at several large congresses, helping physicians and patients to understand and assess risk-benefit for use of metoclopramide with the updated information. We plan to submit these data on the incidence of tardive dyskinesia in patients with gastroparesis for publication shortly.

The upcoming AMCP study that explores the utilization of healthcare resources of 294 patients six months before and six months after initiation of GIMOTI. The study showed patients starting GIMOTI demonstrated fewer all-cause and diabetic gastroparesis related healthcare resource utilization for office, ER, inpatient and outpatient visits for the six-month intervals following initiation of treatment, achieving statistical significance for the diabetic gastroparesis related physician office visits and hospital outcome visits and a numerical improvement for emergency visits.

For all cause related HRU, there was a statistically significant reduction in physician office visits. It's important to note that about half these patients tracked or on oral metoclopramide for a mean duration of 8.1 months prior to switching to GIMOTI, the scientific poster for AMCP should be available on the Evoke Pharma corporate website in the coming days.

And the next study to be delivered at the plenary session for Digestive Disease Week, 257 patients on GIMOTI were compared to a mass control of 257 patients with documented utilization of oral metoclopramide over six months in parallel. These data will provide insight to the question, how does GIMOTI compare to the standard of care for gastroparesis in a real-world setting?

These data are really important to understand as studies suggest that patients with diabetic gastroparesis are admitted to the hospital an average of four times a year and 30% of them are having to be readmitted within 30 days. Cost of the healthcare system is significant and the impact on patients and their families is considerable. We are excited to share these first-in-class data and believe they will add important new information for patient, providers and payers alike.

In summary, I'd like to reinforce we are making positive strides in improving adoption and performance of GIMOTI. By many measures, Q4 was our best quarter to-date. We have tackled barriers and continued to address them proactively and with urgency. We continue to invest in value-generating areas and believe those will bear fruit in 2023. Our goal remains to position GIMOTI as standard of care for patients with diabetic gastroparesis. This year, we'll be focused on building on the confidence in GIMOTI and in the programs and services surround information. If we're going to change the status quo, then confidence is the currency with which we have to deal in.

With that, let me turn the call over to Matt to discuss financials.

Matthew D'Onofrio

Thanks, Chris.

Let's turn quickly to financials. As Dave mentioned, for the fourth quarter 2022, net product sales were approximately $796,000 compared with $361,000 during the fourth quarter 2021, and the net loss was approximately $1.8 million or $0.54 per share compared with $1.7 million or $0.61 per share for the fourth quarter of 2021.

For the year ended December 31, 2022, net product sales were approximately $2.5 million compared with the approximately $1.6 million for the year ended December 31, 2021, and the net loss was approximately $8.5 million or $2.62 per share compared with a net loss of $8.5 million or $3.18 per share for the year ended December 31, 2021. And the annual net losses per share reflect the company's June 2022 1-for-12 reverse stock split.

The year-over-year increase in revenue was due to higher net product sales in 2022 resulting from: increased face-to-face interactions with physicians, primarily gastroenterologists, and other healthcare providers with our sales partner, EVERSANA; greater numbers of physicians within larger groups prescribing GIMOTI after their first-physician adoption; and more increased sales through our vitaCare prescription service partner.

Research and development expenses totaled $27,000 for the fourth quarter of 2022 compared with $36,000 for the fourth quarter of 2021. And for the full year of 2022, research and development expenses were approximately $0.3 million compared with approximately $0.6 million for the prior year. Since receiving FDA approval of GIMOTI in June of 2020, Evoke's research and development costs continue to decrease and shift to commercialization and selling costs.

For the fourth quarter of 2022, selling, general and administrative expenses were approximately $2.3 million compared with $1.7 million for the fourth quarter of 2021. For the year ended December 31, 2022, selling, general and administrative expenses were approximately $9.6 million versus approximately $8.9 million for the year ended December 31, 2021. The increase in SG&A costs year-over-year resulted primarily from shifting personnel costs from research and development to commercialization costs along with higher marketing, royalty and EVERSANA profit sharing costs. We expect that selling, general and administrative expenses will increase in the future as we continue to progress with commercialization of GIMOTI and we reimbursed EVERSANA from the net profits attained from the sales of GIMOTI.

Total operating expenses for the fourth quarter of 2022 were approximately $2.3 million compared with $1.8 million for the same period of 2021. And for the year ended December 31, 2022, total operating expense were approximately $10.3 million compared with approximately $9.8 million for the full year of 2021.

As of December 31, 2022, cash and cash equivalents were approximately $9.8 million. We believe based on our current operating plan that our existing cash and cash equivalents as well as future cash flows from net product sales of GIMOTI will be sufficient to fund our operations at least in the third quarter of 2023.

And finally, Evoke currently holds the majority of its cash at Pacific Western Bank within the [ISC] (ph), or insured cash sweep, accounts. These accounts move funds into separate FDIC insured accounts of up to $250,000 each on -- per day and is available as needed.

And with that, we'll open up the call to questions. Operator?

Question-and-Answer Session

Operator

Thank you, sir. [Operator Instructions] And we'll take our first question from Yale Jen with Laidlaw & Company. Your line is open.

Yale Jen

Good afternoon, and thanks for taking the questions, and congrats on the quarters. A couple from -- the first one is that you mentioned that for the fourth quarter you have a more under and uninsured patients. And what do -- you anticipate that to reduce in 2023? Was there any sign to suggest that of the first three months of this year?

David Gonyer

Thanks, Yale, for the question. No, so far in this first quarter, we haven't saw -- a little maybe trickle in January, but since then, we haven't.

Matthew D'Onofrio

Yes. And yes -- this is Matt. I don't think there's any predictive quantities around it, other than, as you know, sometimes around year-end and the beginning of the year, changes in plans and other things can cause hiccups around reimbursement for individuals as they move from one insurer to another. So, I think there's maybe a very slight seasonal effect that you can see in the end of the year kind of timeframe, but nothing otherwise.

Yale Jen

Okay. The second question is that maybe related, which is cost of goods for the fourth quarter, again, is substantially higher than the previous three quarters. What have caused that? And would you anticipate this cost of goods ratio to continue for the 2023?

Matthew D'Onofrio

Yale, yes -- so, I appreciate your question. I guess, we don't view this as being substantially out of whack, considering the increase in total product that was being sold. It's possible I suppose that based upon some of the earlier product that had been manufactured prior to launch that may have been expensed prior to launch itself that may have added to it slightly. But otherwise, we wouldn't expect it to be anything significant there.

Yale Jen

So, are you suggesting that the current cost of goods ratio -- the margin probably will be similar in 2023?

Matthew D'Onofrio

Yes.

Yale Jen

Okay. And two more quick ones. The first one is that the GIMOTI has been added to the ACG guidelines. Does that impact on the future, I guess, sales as well as reimbursement? And typically adding to the guideline will have sort of positive impact. Just, what's your thoughts?

David Gonyer

So, certainly, being added to the ACG guidelines is a very positive step for a product and many physicians look to the guidelines for guidance in terms of what -- how to deal with new therapy. So, it's definitely a positive. As I mentioned, as we are out there with our field sales organization talking to physicians, physicians appreciate the fact that we've been added to the guidelines and added to that first-line positioning. So, it's added a lot of credibility and built confidence in physician prescribing. It still remains to be seen whether that coupled with some of the evidence generation that we are building will help us to get access for payers.

Yale Jen

Okay. Maybe the last question here is that earlier, I think in this last year, you guys have mentioned that you might have to do a Phase IV study. Does that still -- could that be the case in 2023? And if so, would that impact on the R&D expenses for 2023? And thanks for answering those questions.

David Gonyer

Yes, no problem. Yes, we're still talking to the FDA about working through that trial. It's still taking time to get agreement to what that trial would look like. So, we don't have any expectations at least in the first half probably the end of 2023, if any.

Yale Jen

Okay, great. Thanks a lot. I really appreciate, and thanks.

David Gonyer

Thanks, Yale.

Operator

Thank you. [Operator Instructions] All right. We have no further questions in the queue. So, this does conclude that portion of today's call. I would now like to turn the call back over to Dave Gonyer for any additional or closing remarks.

David Gonyer

Great. Thank you.

I just wanted to close by saying that our effort to make GIMOTI the standard of care for diabetic gastroparesis got a major boost last year in the areas that we outlined today. I just want to remind everyone that GIMOTI is a novel product still in its launch phase, and such times come with both exhilarating growth and humbling times like the slight decrease in Q4 revenues that we saw though prescriptions were 8% higher. Nonetheless, our trajectory is on a steep positive curve and we look forward to executing on our strategic plan and reporting the results for the remainder of the 2023.

Thank you very much for your time.

Operator

Ladies and gentlemen, this concludes today's Evoke Pharma Fourth Quarter and Full Year 2022 Earnings Call and Webcast. You may disconnect your line at this time, and have a wonderful day.
