Doug Godshall -- President and Chief Executive Officer

Thanks, Debbie. Good afternoon, everyone, and thank you for joining us today. I'm pleased to welcome you to Shockwave's call to review our second quarter 2019 results. It has been encouraging to see that the positive trends we witnessed at the end of 2018 and in the first quarter of this year have continued through the second quarter. We reported $10 million in revenue for the second quarter of 2019, which is up $2.7 million over the prior quarter and was a four-fold increase over our second quarter of 2018.

As we saw in the first quarter, growth in the U.S. came principally from M5, our above-the-knee peripheral catheter, and internationally from C2, our coronary catheter. This mix of products and geographies continues to confirm out thesis that intravascular lithotripsy has a potential to play a significant role in addressing a meaningful global patient population. Based on these encouraging results and despite the predictable summer seasonality of U.S. peripheral and international coronary procedures, we now expect revenue for the full year 2019 to be in the range of $38 million to $40 million. Dan will provide more financial details later in the call.

Before turning the call to Dan, however, there are a few highlights from the quarter that I would like to share. Since drug-coated balloons, or DCBs, and the FDA's position relative to their use has been top of mind for many, I want to start by addressing that topic and what, if any, impact it has on Shockwave. And the short answer is that it has had little to no impact. While the FDA panel meetings back in June were inconclusive, the general feeling was that they were somewhat positively in favor of DCBs, and we assume that the FDA will be less negative than in their most recent statements when they update their position publicly. We continue to believe that the future usage of DCBs will be higher than it has been in the past six months but lower than usage had been in 2018.

In recent months, there was a rather meaningful reduction in DCB volume, and yet we did not witness an obvious impact on IVL usage, even in the sites that had completely stopped using DCBs. This suggests to us that IVL usage has been and will continue to be largely uncorrelated with DCB utilization. Organizationally, we have elected not to focus on this saga and have continued to concentrate our efforts on maintaining great outcomes, adding new sites, and educating new users within existing sites. Our recent results suggest that these were the right things to focus on.

While the DCBs challenges did not affect our business, they did have an impact on the randomized arm of our Disrupt PAD III study, which is our global, post-market study evaluating the benefits of Shockwave prior to drug-coated balloon versus angioplasty followed by drug-coated balloon. Given that both arms of the trial include DCBs, we had suspended enrollment of the study pending the FDA panel meetings in June. We have reviewed the FDA panel results with our principle investigators and anticipate FDA will require additional risk language in patient informed consents for DCBs studies. Once we have the final FDA position, we will revise our study documents and restart the study.

As a reminder, there are two arms of the PAD III trial: the 400-patient randomized arm just discussed and a 1,000 patient registry. Given that we have enrolled over 800 patients to date, we are now planning to expand this registry arm beyond 1,000 patients to ensure that we are able to accumulate enough below-the-knee patients to create a meaningful dataset for this important population that has a very high incidence of complex calcification. This expansion is still in the planning stages, but we anticipate a revised protocol will be at our sites in the next few months. Turning to our coronary studies, our 442-patient U.S. IDE study, Disrupt CAD III, enrolled 76 patients in the second quarter, bringing our total patient enrollment to 108 as of June 30th. Of the 50 sites that will ultimately participate in the study, 27 were activated by the end of the quarter, and we remain on track to complete enrollment in the second quarter of 2020.

In Japan, we continue to move forward in discussions with the country's Pharmaceutical and Medical Device Authority, or PMDA, to gain [inaudible] approval of intravascular lithotripsy for coronary use based on the combined data from our Disrupt CAD III and Disrupt CAD IV studies. As a reminder, the Disrupt CAD IV study is a 60-patient pre-market clinical trial notification, or CTN. We expect to initiate enrollment this fall with ultimate approval in mid-2022 in Japan, which is a bit later than originally planned since PMDA is requiring one-year follow-up. One final comment on coronary trials, we look forward to TCT or data from our 120-patient post-approval European registry, CAD II, has been accepted for presentation and will represent the largest IVL coronary dataset to date.

We are pleased with the progress we have made on the clinical study front, and there have been many recent opportunities to conferences to show the capabilities of Shockwave's technology and the data our investigators have generated. EuroPCR was the biggest event this past quarter and was a whirlwind for our team. There were four live Shockwave cases, intravascular lithotripsy with a subject of roughly 45 presentations, and we witnessed standing room only audiences at many of the Shockwave sessions, including at our six Abiomed Shockwave combined training events. One of the IVL cases that was presented by a physician from Belfast was voted by the congress to be the best case presentation at PCR this year, and that was out of 1,300 case presentations of all different types -- quite flattering to say the least.

In addition, we hosted a coronary top shock IVL case contest where we asked customers to submit their toughest Shockwave cases to be judged by a panel of physicians. The winner was a great case where Rotablator and Shockwave were used synergistically to manage a very challenging patient. Our international customers really seemed to enjoy this event. This year's PCR was a great representation of the versatility of intravascular lithotripsy in the coronaries and demonstrated how rapidly our European customers have integrated Shockwave's coronary system into their practice in just one year.

In addition to EuroPCR, we also had great visibility at many other conferences, included NCBH, SVS, C3, TBT, and Sky. And Shockwave was used in multiple live cases as well as 11 symposia at the various conferences this quarter. We experimented with a new concept at TBT where we held our first large-bore access session. TBT does not have any coronary or peripheral contents or the physicians who attended this symposium were not the peripheral or coronary users who ordinarily frequent our sessions, but rather, it was a group of practitioners focused strictly on using Shockwave to expand calcified iliacs for TAVR or Impella placement. This focused, large-bore symposium nicely complements our commercial strategy where we are increasingly using iliac access as our entry point at many U.S. accounts, and once on the shelf, we broaden to other peripheral applications.

Also on the commercial front, our field staffing efforts are tracking consistently with our goal to expand Shockwave's direct presence in the U.S. and Europe by roughly 50% of the course of 2019. We also added two regions in the U.S., which brings us to four, so we now have more local management to help support our specialist and sales teams. Internationally, we are selling in 33 countries, and while we have witnessed encouraging adoption in many countries, the vast majority of sites and physicians have yet to even try Shockwave. We are just getting started.

We also continue to see steady progress in our collaboration with Abiomed. We held a joint Shockapella advisory board meeting in June, conducted training at multiple conferences, and are piloting field-based partnerships to refine how we will jointly approach local customers. We anticipate there will be an increasing frequency of training sessions locally and at medical conferences. The more Impella users become aware that they can use IVL to easily and safely expand the iliac arteries to place Impellas in the presence of calcium, the more Impellas Abiomed should sell, and by extension, the more M5s Shockwave should sell.

There are additional benefits from this partnership for Shockwave, of course. First, many Impella users also do TAVR cases where IVL can help avoid alternative access, or #stayfemoral, as one of our customers has coined. And even if those we train with Abiomed choose not to use Shockwave for large-bore access, the vast majority of Impella users also treat coronaries, so there will be meaningful exposure and awareness of Shockwave well in advance of our U.S. coronary launch in 2021.

With respect to our below-the-knee products, we are still highly encouraged by the clinical response to our S4 device, which will remain in limited launch mode while we prepare to roll out smaller sizes and to fully launch S4 in the fourth quarter of this year. A quick note on intellectual property, as you may have seen, the U.S. Patent and Trademark Appeal Board, or PTAB, has decided to officially institute the IPRs on three of our patents. While the decisions do unfortunately draw out the IPR process and requires us to go to trial, we remain quite confident in our broad patent portfolio and strategy and are not concerned about the impact of these IPRs on the viability of our business as we move forward.

Turning to operations, behind the scenes, our team has really impressed me with their dedication and performance. Our operations team has been on fire since January. We've had a two-fold increase in production. Our second shift is now fully up and running and almost matching the first shipped and daily output, and we doubled our cleanroom space with the move to our new Santa Clara facility that we just completed. On top of all this, we successfully managed audits from FDA and our European notified body just as we were preparing to move. The FDA was extremely complimentary, which is a good sign to say the least. Together, the move and inspections were great tests of our capabilities, and the team passed with flying colors. Despite the risk of disruptions for move preparations and inspections, we continued steady improvement and production on both shifts without any associated quality issues, again, a strong testament to the strength of the team and integrity of our systems and processes.

And in conjunction with increased sales, a larger facility, and production increases, we have also grown our team. As of June 30th, we had over 210 employees, an increase of 52 from the beginning of the year, as we added key organizational areas across the board, including program management, marketing and sales, clinical R&D, and regulatory operations. We also are delighted to have recently announced the addition of both Haj Tada as General Counsel and Keith Dawkins as Chief Medical Officer. We will continue to enhance our capabilities to ensure that we are in the best possible position to take advantage of the meaningful opportunities in front of us.

With that, I would like to turn the call to Dan.

Dan Puckett -- Chief Financial Officer

Thank you, Doug. Good afternoon, everyone. Shockwave Medical's revenue for the three months ended June 30th, 2019 was $10 million, a 339% increase from $2.3 million in the same period of the prior year. U.S. revenue was $5.2 million in the second quarter of 2019, growing 239% from $1.5 million in the same period last year, all of which was derived from our peripheral products. This increase in U.S. revenue was driven primarily by M5, our above-the-knee peripheral catheter. International revenue also saw nice increase in the quarter, growing 543% to $4.8 million in the second quarter of this year, from $752,000 in the same period last year. The main driver of our international revenue was our C2 coronary product, which is supported by a network of 18 distributors for selling in 33 countries, including newly added territories in Eastern Europe and Asia.

Looking at revenue by product line, peripheral products accounted for $6.2 million of total revenue, compared to $1.9 million in the same period last year, a 223% increase. Coronary products accounted for $3.5 million of the revenue, compared to $348,000 in the same period last year, all of which was international. In addition, the sales of generators, most of which was international, contributed $297,000 revenue in the second quarter this year, and there was no generator revenue in the same period last year.

Gross profit for the second quarter of 2019 was $5.9 million, compared to $1.1 million for the second quarter of 2018. Gross margin for the second quarter of 2019 was 59%, as compared to 48% in the same period last year. Contributors to gross margin in improvement included continued increased absorption of our fixed costs and productivity gains through workflow improvements and fixturing.

Total operating expenses for the second quarter of 2019 were $17.1 million, a 52% increase from $11.3 million in the second quarter of 2018. R&D expenses for the second quarter of 2019 were $6.9 million, compared to $5.5 million in the second quarter of 2018. The increase was primarily attributable to clinical study expenses for ongoing PAD III, CAD II, and CAD III trials. Sales and marketing expenses for the second quarter of 2019 were $7 million, compared to $4.4 million in the second quarter of 2018. The increase was primarily due to salesforce expansion in the U.S. and internationally as well as increases in marketing program spending. General and administrative expenses for the second quarter of 2019 were $3.2 million, compared to $1.4 million in the second quarter of 2018. This increase was primarily due to additional costs associated with being a public company.

Net loss for the period was $10.6 million, as compared to net loss of $10.1 million in the same period of last year. Net loss per share in the second quarter of 2019 was $0.38. We ended the second quarter of 2019 with $125.1 million in cash, cash equivalents, and short-term investments.

Turning to our outlook for 2019, we're continuing to see strength in our peripheral products and accelerated use by our existing and new customers globally. In addition, we're expecting to see continued geographic penetration of our coronary product internationally. Based on these trends, we expect full year 2019 revenue to be in the range of $38 million to $40 million, representing a growth of 210% to 226% over full year 2018.

At this point, I would like to turn the call back to Doug for closing comments.

Doug Godshall -- President and Chief Executive Officer

Thanks, Dan. Thank you all again for taking the time to join us today. We are so pleased with the progress our company and technology have made and are grateful for the exceptional support we've received from physicians around the world. These accomplishments each quarter are building upon each other to establish Shockwave as an effective solution that can help transform the way that calcified cardiovascular disease is treated.

...

With that, I would like to open the line for questions.

Our first question or comment comes from the line of Lawrence Biegelsen from Wells Fargo. Your line is open.

Lawrence Biegelsen -- Wells Fargo -- Senior Medical Device Equity Research Analyst

Good afternoon. Thanks for taking the question and congrats on a really nice quarter.

Doug Godshall -- President and Chief Executive Officer

Thanks, Larry.

Lawrence Biegelsen -- Wells Fargo -- Senior Medical Device Equity Research Analyst

Doug, I wanted to just ask up front within the U.S. in peripheral -- can you hear me OK, Doug?

Doug Godshall -- President and Chief Executive Officer

Yes.

Lawrence Biegelsen -- Wells Fargo -- Senior Medical Device Equity Research Analyst

Good. Sorry, I wasn't sure there. So, maybe just in the U.S. in peripheral, could you tease out a little bit SFA use versus large-bore access, how much use you're seeing in each of those? And I had a couple follow-ups.

Doug Godshall -- President and Chief Executive Officer

We're not at this juncture splitting out vessel-specific, but I would say the momentum we saw on this quarter was certainly driven a bit more by common femoral iliac acceleration, although SFA certainly continued to contribute very nicely, but the acceleration, getting on the shelf, and broader visibility and awareness of the applicability in the iliacs were sort of a bigger contributor this quarter than it was last quarter. But it's not like it started to dominate the SFA. SFA is still a very significant part of the business.

Lawrence Biegelsen -- Wells Fargo -- Senior Medical Device Equity Research Analyst

That's helpful. And Doug, I heard your comment on below-the-knee, which were encouraging. That's obviously a pretty important catalyst for you guys and growth driver. Maybe just a little more color around your confidence in the smaller sizes. I think it's the 2.5 and the 3.0 we're waiting for by year end, and just from a process standpoint, what's left in front of you before bringing these smaller balloons to market? And I just have one more follow-up.

Doug Godshall -- President and Chief Executive Officer

Since we had to make the balloons a bit thicker and move the spec outside of the original range, we had to submit to the FDA, so we're waiting for FDA approval. It's certainly not a complicated submission. It's essentially the same balloon, just a little bit more durable, and so we're pending that approval, and then we'll do a limited launch to make sure that we were right. But given that we're already getting nice feedback from the limited launch of the 3.5 and the 4.0, it will not be as lengthy a limited launch once this is available.

Lawrence Biegelsen -- Wells Fargo -- Senior Medical Device Equity Research Analyst

That's helpful. And just last for me, Doug or Dan, since you're a new public company, it would be helpful to hear from you just kind of the cadence that you expect for Q3 and Q4. You talked about seasonality a little bit. I'm sure everybody's aware of that particularly in Europe, but maybe the low end of the guidance range. I think the second half is about $21 million to $23 million implied from doing the math, right? The low end implies somewhat flattish growth, sequentially from Q2, but just maybe helpful to hear from you how you're thinking about the guidance and maybe any conservatism at this point, given that you're a new public company and seasonality. Thanks for taking the questions.

Dan Puckett -- Chief Financial Officer

Sure, Larry. Maybe I'll comment on that. It's Dan. We do expect some seasonality in Q3 due to the summer holidays internationally and in the U.S., but we do still expect sequential growth and then seeing growth pick up significantly again in Q4.

Doug Godshall -- President and Chief Executive Officer

And Larry, and I'll add some color. What is encouraging about the broad acceptance of coronary also puts us a little bit earlier on the seasonality trend than maybe other companies at our stage. And so, while we have not lived through a European seasonal trend yet, it seems predictable that when you have a fairly wide geographic distribution, as we now do, in 33 countries which is led by coronary, and just getting on the shelf at new sites, which would enable you to overcome that procedure lull that happens particularly in August, it's a little bit harder to overcome the seasonality, so we're mindful of the fact that we're still looking to add as many sites as we can, but we are new enough that we don't have as much experience as, say, a larger company would to have as much granularity on seasonality, but it seems predictable that we'll be seeing it.

Lawrence Biegelsen -- Wells Fargo -- Senior Medical Device Equity Research Analyst

Thanks for taking the questions, guys.

Operator

Thank you. Our next question or comment comes from the line of Jason Mills from Canaccord Genuity. Your line is open.

Jason Mills -- Canaccord Genuity -- Managing Director

Hi, Doug and Dan. Congrats on a great quarter. Can you hear me OK?

Doug Godshall -- President and Chief Executive Officer

Yup. Thanks, Jason.

Dan Puckett -- Chief Financial Officer

Thank you.

Jason Mills -- Canaccord Genuity -- Managing Director

Great. I wanted to ask Doug first about coronary. Could you talk about what trends you're seeing? Obviously, you had a good quarter in coronary OUS. Is it a potential leading indicator of what we might expect in 2021? What can you say about the adoption trends? Any dynamics you're seeing in Europe using the coronary catheter that you think are applicable as we think about the coronary launch in the United States in a couple years?

Doug Godshall -- President and Chief Executive Officer

Sure. We seem to be, thus far, highly complimentary to atherectomies in that we are enabling physicians to treat a lot of vessels and vessel types that they are either reluctant or unable to treat with atherectomy, and just as was evidenced in that case that won the contest at PCR, we're seeing a reasonable amount of Rotablator-Shockwave combos, so cases where maybe they could've gotten across a tight lesion with a Rotablator before, but then they couldn't treat a left main, or they couldn't treat a really torturous anatomy, or an osteolesion, or the like, now they can do both, and they can interventionally get a patient more fully revascularized and complete the procedure. So, all the evidence that we've seen thus far in Europe and in other geographies is that we are meaningfully expanding the treatment of calcified coronary vessels and not in a position where either they send a patient to surgery or they deploy a stent, and hope for the best, and end up with stents that aren't fully deployed.

So, I think that should have a fairly direct corollary when we launch in the U.S. It ought to be a pretty similar practice pattern, certainly in the U.S. There's more atherectomy utilization than there is in Europe, sort of a twice-as-much utilization on a per-procedure basis, but it's still circa 5% versus circa 2.5% in Europe. So, given that we think based on everything, all the feedback we're seeing from Europe, the 20% to 25% calcified artery estimate is not inaccurate, not that we're predicting we're gonna get all 25%, but that's a real incidence prevalence, so there's a huge amount of upside between 5% and 25%.

Jason Mills -- Canaccord Genuity -- Managing Director

Got it. That actually proactively answered one of my follow-up questions, which is any change to your targets from market expectations you've laid out, so I'll move on to another coronary question. You meaningfully accelerated, Doug, the CAD III study enrollment in 27 of the 50 sites here in the United States. Just in those sites with the current run rate, it looks like you're on track to meet Q2 2020 completing the enrollment. Should we expect, though, that enrollment might accelerate some as more sites come on, and is there a potential upside to enrollment completion for CAD III?

Doug Godshall -- President and Chief Executive Officer

If you straight-line the enrollment from the second quarter, you'd probably be tail end of second quarter, so we are hoping to see an increase in patients per month. Certainly, we've had some really encouraging early strong enrollers, but we're also now gonna continue to expand and hopefully get to the full 50 in the not-too-distant future, so our clinical team is doing a remarkably good job. They're really tight, similar to our operations team, and they're well aware of our desire to get this trial enrolled as expeditiously but with spectacular data, obviously, and the sooner we get enrolled, the sooner we'll be approved, so they're not unaware of our collective desire to get it enrolled as fast as we can without sacrificing quality.

Jason Mills -- Canaccord Genuity -- Managing Director

That's helpful. I'll ask one more. I'll get back in queue. Specifically to the below-the-knee, in the S4, the soft launch, our checks would suggest there's quite a bit of demand and interest in getting access to that product. Could you talk about how quickly you might go or how you might roll that out when you do have the 2.5 and 3.0s available and what sort of qualitatively you can say about physician interest in that product, specifically in the United States? But I'd be interested in what you're seeing in terms of interest outside the U.S. where obviously peripheral atherectomy is not as superfluously used. Talk a little bit about S4 and qualitatively what you're hearing.

Doug Godshall -- President and Chief Executive Officer

So, we've still been in a narrow set of accounts and are looking to broaden the limited launch outside of some of the hardcore Shockwave sites. The feedback has certainly been encouraging. The product is giving them a tool that they don't otherwise have. We are also being used in a complimentary fashion to atherectomy below the knee a bit more than I had even expected, frankly, so you're able to treat with CSI and finish with Shockwave or treat part of it with Shockwave, treat part of it with CSI with Diamondback, so interesting correlate to what we've seen in the coronaries, although certainly, that's a subset of the cases. There are lots of Shockwave-only cases in our limited launch as well.

So, yeah, we're really eager to see how differently the roll-out is below the knee versus our M5 rollout above the knee, given that it's in some ways more straightforward because it's not iliac for TAVR access or EVAR access or the like. It's a straightforward peripheral case, and these are among the most critically ill patients that we deal with, even more so than some of our coronary patients because you're trying to avoid an amputation, which is, I think, probably some of what you're hearing in terms of the interest in having that product. Once the smaller sizes are available, as I mentioned before, we'll do a limited release, hopefully early in the fourth quarter, and then there's some really good peripheral meetings, as you know, in the fall, and we'll look to have at least a broader splashier launch there in the mid-fall.

Internationally, we've got a bunch of distributors who are very focused on coronary right now for good reason. Distributors tend to seek the path of least resistance, and if all your customers are telling you they want coronary, then you sell that because it's easier to sell. We are adding some market development capabilities to support those distributors to help generate peripheral demand, and below-the-knee demand specifically, and so we'll have sort of a hybrid, some direct support of distributors to make sure that we help educate them that there's a great Shockwave opportunity in the periphery, which some of them are already starting to look to iliacs as their next Shockwave market, and we'd like to then have below-the-knee being the one to follow. So, little more nascent internationally, and it's in part because we're really early in the launch in coronary, and it would be a little hard to get their attention away from coronary, particularly distributors. Our direct personnel will be able to juggle both, but the distributors less so.

Jason Mills -- Canaccord Genuity -- Managing Director

Got it. Thanks, Doug.

Operator

Thank you. Again, ladies and gentlemen, if you have a question or comment at this time, please press *1 on your telephone keypad.

Our next question or comment comes from the line of Bob Hopkins from Bank of America. Your line is open.

Bob Hopkins -- Bank of America Merrill Lynch -- Managing Director

Great. Thank you. Hey, guys, just a couple of quick questions here. First, on the PAD III trial, I'm not surprised to hear your commentary about the need for additional risk language required from FDA on paclitaxel trials going forward, but I'm just curious have you talked directly to FDA about this at this point? Have you had conversations with the FDA post the paclitaxel panel? Just kinda curious as to what you're hearing and how long you think it'll take to get restarted there.

Doug Godshall -- President and Chief Executive Officer

We have not. This is a post-approval study. I think they would probably tell us go ahead and do your trial, but I don't wanna go out with our guess at what risk language should be and then go back to the IRBs and revise it again. And thankfully, we're looking forward to getting it started, but it's not as if this is mission critical, what are we gonna do without PAD III. In some ways, it helps us because our clinical specialists are all getting certified for coronary support right now, and that's our key clinical mission, and if we were trying to both reramp PAD III, which our clinical specialists do a great job supporting, but it takes time. I'd frankly rather them spend time on coronary than on peripheral right now, so a little bit of a rain delay from FDA is not actually inconvenient at all. It's kinda convenient.

Initially, we thought from the folks who we're very involved with that the FDA might come out with a position very quickly, like last month, which obviously didn't happen, and now we're hearing it might be September, but I don't have any direct knowledge or feedback from the FDA.

Bob Hopkins -- Bank of America Merrill Lynch -- Managing Director

And then, just one quick follow-up on below-the-knee and smaller sizes, I heard your comments about obviously first a limited launch, and given your experience to date, you're seeing more cases maybe than you expected with atherectomy, but is it safe to say that the majority of the cases are probably gonna be either/or your therapy or atherectomy therapy rather than together?

Doug Godshall -- President and Chief Executive Officer

Probably. I think the Venn diagram will have a reasonable intersection though because they are different, and if you've got a bifurcation, you might really wanna use Shockwave for a bifurcation, or if you've got a single-vessel runoff, you might really wanna use Shockwave, but if you've got a long, straight segment, you may wanna just spin something down there and treat that with atherectomy. That's one of the things we're trying to digest and internalize from our limited launch is how will we be positioned, where's the best place to use Shockwave versus angioplasty, versus atherectomy if it is versus atherectomy. My hunch is just like the coronaries, we're gonna be a new tool that enables them to better treat patients who were primarily getting balloons, or in the coronaries case, we're just getting direct stented, so I anticipate that the primary move will be from, at least based on what we're seeing so far in the legs, it would primarily be balloon to Shockwave versus atherectomy to Shockwave in terms of a share shift.

Bob Hopkins -- Bank of America Merrill Lynch -- Managing Director

Got it. That's helpful. Thank you.
