Michael Perry -- President and Chief Executive Officer
Thank you, Caroline, and thank you everyone for joining us today. As some of you know, this is our first earnings call following the redomiciliation of AVITA from Australia to the United States and the initiation of NASDAQ as AVITA's primary listing. I'm very pleased that we have now fully aligned our corporate structure with our US-based operations and we continue to focus on our core goal of driving RECELL in both the commercial setting and in our multiple pivotal clinical trials.
I'm looking forward to updating you on our performance for our fiscal first quarter, which ended September 30. But first, since many of you who are listening today are relatively new to AVITA, I thought it would be helpful to initially provide a brief overview of our story and why we believe AVITA's established commitment to clinical research provides unique growth opportunity across multiple markets. AVITA is a commercial stage regenerative medicine company, with proprietary technology that harnesses the body's own healing powers to provide skin restoration at the point-of-care. In simple terms, our offering, which is marketed as the RECELL System is best described as Spray-On Skin Cells. Clinicians take a postage stamp size sample of the patient's own skin and use the RECELL System to prepare an autologous cellular suspension, meaning a fluid like spray, and then apply this suspension on the wound or defect to regenerate natural, healthy epidermis or skin, including restored natural pigmentation.
Before RECELL burn patients received skin graphs from other parts of their bodies, which made for a large secondary wound, or if the graph was meshed or stretched out, they saw poor aesthetic outcomes once they healed. Our Spray-On Skin was the subject of two randomized controlled clinical studies in the United States and these studies underpinned our FDA pre-market approval, or PMA, in late 2018. Importantly, these studies confirmed that the RECELL System delivers clear, well-defined clinical benefits by dramatically reducing the amount of donor skin required to treat second and third degree burns.
Our clinical studies along with our published health economics model, collectively confirm other important benefits, including reduced donor site pain and scarring, a 30% to 35% reduction in both length of stay in hospital and number of procedures, plus a 35% reduction in total costs to the hospitals. With these attributes, the RECELL System truly provides win-win benefits to physicians, patients, hospitals, and payers. Notably the RECELL System PMA was the first in burn care in more than 20-years. And we began our commercialization efforts within the hospital inpatient setting in early 2019.
With these milestones behind us, we are progressively realizing our mission of providing incredible life-changing outcomes for burn patients. And we're seeing consistent confirmation that the RECELL System is a transformative therapy within the burns community. While it's difficult to characterize the broad assortment of burns that the RECELL System is used to treat, an example that resonates with many people is a 12-year-old girl, who had catastrophic burns to more than 60% of her body, including her face, following a car explosion during refueling at the gas station. Without RECELL, this patient would have been hospitalized for months with numerous painful repeat skin grafting procedures. However, with the RECELL System, as part of her treatment protocol, she was discharged from hospital in only 24-days and importantly, she saw the return of her natural pigmentation and skin texture.
With our recent experience, we are becoming increasingly confident that the RECELL System is rapidly evolving to become the standard-of-care within the inpatient burn setting, which we see as a $200 million market opportunity with little competitive headwinds. Today, we are very proud to have used the RECELL System to treat over 10,000 patients globally across various indications and our 186 peer reviewed publications and podium presentations describing outcomes, and over 2,000 patients are a testament to our commitment to deepening our clinical experience.
Additionally, our determination to seek and obtain the highest standard of regulatory approval via data supported PMA studies rather than five, 10-K approvals, and our proven ability to regenerate epidermis uniquely positions us to both grow within burns and pursue new market opportunities. In parallel with our commercialization efforts in burns, we initiated a series of pivotal clinical studies within the United States that seek to leverage our existing PMA via various label expansion opportunities. These indications involve potential applications of the RECELL System for patients, who have lost their epidermis through injury or accident, or for those patients, who have compromised epidermis due to skin defects or underlying abnormalities.
I'm particularly excited about the opportunities and pediatrics calls when, for example, a child knocks over a hot pot of water or coffee and in vitiligo, which is a patchy skin disease where the natural skin color is lost, most famously associated with Michael Jackson. I have a few updates to share for these two examples a bit later.
Beyond our near-term pipeline efforts, I will also mention that we are exploring applications for use of the RECELL System within the cell and gene therapy arena. As many of you maybe aware, there are a large number of skin disorders that present as skin fragility, skin blistering or skin irritation, and can be life-threatening or incredibly debilitating. Some of these are incurable disorders caused by gene mutations and a number of groups are pursuing gene editing technologies to correct these mutations.
In this context, we believe that Spray-On Skin cells could be the ideal delivery vehicle for these offerings. In this way, we're looking to partner with cell and gene therapy companies to administer their therapeutic treatments using the RECELL System. We have entered collaborative research agreements with the University of Colorado to evaluate delivering genetically modified cells for epidermolysis bullosa and with the Houston Methodist Research Institute to leverage their reverse aging technology for skin rejuvenation. Our gene therapy delivery efforts are still in early stages of R&D. And I look forward to updating you as we continue our proof-of-concept efforts for those two opportunities.
So, with that brief background on AVITA, I'd now like to turn to our performance in our fiscal first quarter. You may have seen it in our pre-release issued in September that we made solid progress, despite the macro challenges that reverberated across the broader market, due to the COVID-19 pandemic. While the treatment of burns patients is both an emergent and non-elective procedure, AVITA and the RECELL System are not impervious to the wave of disruption that has been generated by the recent outbreak of COVID.
In short, the combination of dramatically reduced economic activity, social distancing, and restrictions on mobility have reduced the number of burn accidents. And this resulted in a dramatic reduction in procedural volumes in April. We saw some recovery in May and June to generate a flat fiscal fourth quarter ended in June, as compared to the March third quarter. This recovery trend continued into September quarter, with the delivery of our highest month of revenue ever in July, our highest quarterly revenue figure of $5.1 million and our highest quarter ever for procedural volume.
To summarize, revenue was up 31% in the September quarter versus the June quarter. And procedural volume also increased 27.2% to 496 sequentially. Importantly, we're seeing increasingly broad utilization of our product with 57 unique customer orders of the RECELL System in July alone. During the September quarter, we added nine new accounts to finish with 86 accounts with purchasing approval for the RECELL System, and we saw very broad use of RECELL across different wounds sizes, injury types, and anatomic locations. While the resumption of sales growth has been extremely gratifying, the environment in which we operate continues to be challenging in the clinical setting.
Please remember that burn patients and even patients that we are trying to enroll under our pediatric and soft tissue pivotal studies are often being treated in the same institutions that our primary call points for the treatment of COVID patients. For this reason, as you've likely seen broadly across our peer group, access to the hospital setting is incredibly limited, with expensive implementation of restrictive protective practices. In short, opportunities for business development and clinical study enrollment in the emergency and intensive care settings have been impaired with our personnel predominantly permitted onsite at physician requests for the exclusive purpose of attending RECELL procedures in surgery.
While we are seeing some very limited live in-person training activities, our employees are infrequently permitted to engage directly in the aftercare setting once a patient is treated and therefore, live dialogue and access is transient at best, or has otherwise been transferred to a digital format. Unsurprisingly regional in-person burn conferences have all been replaced with virtual meetings.
COVID has also triggered a meaningful slowdown in many clinical trials, as you most likely know. Resourcing and budgeting constraints for participating hospitals, patient unwillingness to return for follow-up visits due to COVID fears, together with restrictive and protective COVID specific practices, such as limited access and visitation are all factors that infringe upon enrollment. More specifically, our pediatric scald and soft tissue studies are also confounded by the simple reality that these studies and their follow-up visits are performed largely in facilities, which are directly dealing with COVID patients. So, there is both a competitive tension for these resources and a fear factor among patients. The emergency room setting is also a non-traditional setting for conducting PMA studies and therefore, frequently lacks focus, investigational study resources, such as clinical trial support staff, which would commonly be available in institutions that are regularly engaging in PMA studies.
Finally, there is no referral pipeline for patients in these sorts of studies, because they are emergent, random and accident driven. The by-product of these factors has made accelerating study enrollment challenging in this setting over the past six months. In our pediatric pivotal study, we are, however, pleased to now have enrolled eight patients, but not withstanding the strong progress, it is important to note that we had near zero enrollment traction in this study during the period from March through August.
In fact, the bolus in enrollment was nearly entirely generated in the September and October timeframe, due mainly to our enrollment push in late summer and the addition of new sites within that window. This more recent enrollment trend is very encouraging and we are hopeful of generating a steady cadence in our pediatric scald pivotal study moving forward, particularly as we look to add new sites over the next few months.
Our soft tissue reconstruction pivotal study has not, however, been able to generate momentum with only two patients enrolled thus far. This study has witnessed periods of enrollment cessation, due to COVID and a loss of patients to off label use of the RECELL System or simple screen failures due to patients being excluded due to contraction of COVID or other confounding, but unrelated medical conditions, such as cancer or mental health issues. For some perspective, we had four potential patients recently, who were excluded due to having contracted COVID. To be blunt, we have been disappointed with our progress in this study, and we're taking this opportunity to take a closer look at this market to determine where the clinical utility lies.
By contrast, many of the impediments that we see for enrollment in the intensive care setting are not evident or are more manageable within our vitiligo pivotal study. It has been a whirlwind start for our vitiligo study, beginning with the granting of our investigation of device exemption in early July, followed by quickly navigating through both investigational review board, or IRB, approval and site contracting to enroll our first patient in late September. As of today's date, we have enrolled eight vitiligo patients with six of those patients being enrolled in the pivotal study in one site, and two patients enrolled in the single site vitiligo feasibility study at UMass.
We have seen a remarkable level of interest in our vitiligo study from physicians, sites and patients, and we have a strong pipeline of sites looking to participate in this trial. For this reason, we believe that vitiligo is likely to be our fastest enrolling study and therefore, our next approved indication for the RECELL System. We are seeing some very strong tailwinds in the broader vitiligo market, which we believe bode well for RECELL and the huge unmet need. Specifically, there are 4.5 million Americans suffering from vitiligo depigmentation with no FDA approved products presently available to provide repigmentation for these patients.
In addition, we expect to see an increasing number of stable vitiligo patients available for RECELL treatment, courtesy of Incyte's new therapeutic topical ruxolitinib. Additionally, Cigna's recent determination of medical necessity and correspondingly strong reimbursement support of $38,000 over a 12-month period points to positive coverage trends for patients requiring vitiligo treatment. These are very strong signals for the RECELL System, as we seek to be the first curative therapy for repigmentation of stable vitiligo patients.
Outside of our commercial growth and clinical studies with the RECELL System, we have also seen good progress elsewhere in our business. Together with our commercial partner COSMOTEC, we continue to focus on regulatory approval in Japan. I am pleased to confirm that we have completed the three required non-clinical benchtop studies in August as scheduled. Our efforts and interaction with COSMOTEC and the Japanese regulatory authority are ongoing. And we are hopeful of advancing our application for marketing approval of the RECELL System under Japan's Pharmaceuticals and Medical Devices Act, or PMDA.
In terms of reimbursement, the company remains on track with its transitional pass-through payment application known as TPT, which will support separate additional Medicare payment for the RECELL System, specifically in the outpatient setting. The centers for medicine and Medicaid services, or CMS, is expected to make its final decision in December with a C code to be implemented with effect on January 1, 2021, assuming no delays due to COVID.
Looking ahead, we're hopeful that the inherent benefits of the RECELL System to patients and hospitals will continue to resonate and that we will see increasing and diversified use of the RECELL System in both our existing customer base and with new customers. Likewise, we're focusing on progressing our pivotal studies and have become very bullish on the vitiligo market opportunity, which we think is in excess of $750 million.
With that, I'll turn it over to Sean for details on our financial performance in the quarter. Sean?
Sean Ekins -- Vice President of Finance
Thank you, Mike. For the first quarter ended September 30, we reported revenues of $5.1 million, compared to $3.3 million in the corresponding period last year and $3.9 million in the June quarter of 2020. Revenues for the first quarter include sales of the RECELL System in the United States a $5 million, an increase of $1.2 million or 31% over the $3.8 million reported for the June quarter.
The gross profit for the September quarter was $4.1 million, representing a gross margin of 82%. This is an increase of $1.5 million from the gross profit $2.6 million of gross margin 81% reported in September, 2019.
The total operating expenses for the September quarter were $14.9 million, which is an increase of $6.6 million, compared to the same period in 2019. The increase in operating expenses was driven primarily by increases in personnel costs, clinical study costs associate with our four clinical studies and the cost associated with establishing AVITA a US public company, including completion of our redomiciliation, the first US GAAP audit for the three-year period ended June, our first proxy statement and our first 10-Q.
Operating losses for the September quarter were $10.2 million, as compared to operating losses of $3.6 million the same period last year. Cash on the balance sheet was approximately $65.8 million as of September 30, 2020.
And now, I'll turn the call back over to Mike.
Michael Perry -- President and Chief Executive Officer
Thank you, Sean. As you've just heard, we have made great progress during the September quarter, with 30% growth in RECELL System sales and strong progress toward our goal of making the use of the RECELL System the standard-of-care in the inpatient hospital burn setting. In addition, our other developments, especially our speedy transition from receipt of an IDE to an exciting early cadence of patients in our vitiligo pivotal study, together with our strong cash position bodes well for an exciting 2021, and we look forward to providing you with updates over the coming months.
This concludes our prepared remarks. And now, I'd like to turn to the operator to open the call to your questions.
Questions and Answers:
Operator
Thank you. [Operator Instructions] Our first question comes from Josh Jennings with Cowen. Your line is open.
Josh Jennings -- Cowen -- Analyst
Hi, good afternoon. Thanks for taking the questions. Mike, I was hoping to just hear a little bit more about the trends you're experiencing since September, and just remind us if there's any seasonality you should be considering in this December quarter that we're currently in, in the burn market. I think the gist of my question is really getting out it, could we see sequential revenue growth in the US? Or should we be thinking about COVID headwinds, some seasonality where sequential revenue growth may not be implied?
Michael Perry -- President and Chief Executive Officer
So, thank you, Josh, for your question. Yes, there is a degree of seasonality that usually hits the October month. November and December are generally picking up to be normal relative to what we generally see. And so far as sequential quarter-over-quarter growth, we do anticipate that we'll continue to grow our business and not have a flat quarter, as we had in the quarter before last. Does that answer your question appropriately?
Josh Jennings -- Cowen -- Analyst
That does. No, thank you for that. And if I could ask just about the outpatient RECELL kit development, the transitional payment is in process. Can you remind us or provide just any color on how you're thinking about and your team's thinking about the launch in 2021, assuming that this transitional pass-through payment is granted at a reasonable level?
Michael Perry -- President and Chief Executive Officer
Yes. What we're thinking of is that if CMS is on time, so we would expect in December an answer from them relative to the transitional pass-through payment. Then we would get a C code that would be effective in January of 2021. With that, we would proceed into the outpatient setting and begin with our high volume centers that are already really clicking along at a high speed and moved to the outpatient setting where we see some smaller wounds, as well as less deep wounds and that's our plan. And so far as the initial rollout then we'll start moving to the centers that are not as well and trenched and expand from there.
Josh Jennings -- Cowen -- Analyst
Thanks, for those details. And then just one last question, just on the pipeline -- and congratulations with all the enthusiasm and the enrollment paid so far in the vitiligo trials. But I wanted to ask a question on skin rejuvenation and the collaboration with Houston Methodist, any more color you can provide that, there will be any milestones in the next 12 to 24 months in that proof-of-concept work that you're collaborating on?
And then, I mean, how do you -- how should we think about just overall timelines for a potential cell therapy for skin rejuvenation from a high level, just to get a kind of framework for when you could -- we could actually see a product? This is a three-year pathway. Is it longer than three years? Any color on that would be helpful? Thanks for taking the questions, Mike.
Michael Perry -- President and Chief Executive Officer
Sure, Josh. Yes, Methodist has developed RNA technology to deliver telomerase and has already demonstrated reversal of aging and return of functionality and the cells from progeria patients. And progeria is a genetic disorder leading to accelerated aging. So, the proof-of-concept is there. The focus and so far as our first milestone will be on telomerase in rejuvenating aged skin cells in a mouse model, and that will be taking about 18-months. But during that time, I'm not sure that we'll wait till the end of the sponsored research agreement. We'll be talking with FDA to make sure that we have all of the safety data required to enable an IND package. And then move forward into the clinic. This could be within the two to three-year timeframe or it could be accelerated depending upon how the initial early research goes.
Josh Jennings -- Cowen -- Analyst
Great. Thanks for that as well. Appreciate it.
Michael Perry -- President and Chief Executive Officer
Pleasure.
Operator
Thank you. Our next question comes from Ryan Zimmerman with BTIG. Your line is open.
Ryan Zimmerman -- BTIG -- Analyst
Good evening. Thanks for taking the questions. Mike, maybe on the procedural dynamics you saw in the quarter, certainly encouraging. Wonder, if you could speak anecdotally to the adoption and whether you're seeing new physician adoption or incrementally higher usage among existing customers? And maybe how that splits out a little bit, any color there, I think would be helpful for people to understand.
Michael Perry -- President and Chief Executive Officer
Yes. Thanks, Ryan. We're seeing both new physician adoption, as well as increased utilization by those, who are using the product on a regular basis. And so far as the split, I would say that the new physician adoption is less of an impact than the existing physicians increasing their use. And that's primarily due to our decreased business development associated with COVID. As I said in my prepared remarks before we went into the Q&A, our sales reps are being allowed into the surgical suite upon request by the physicians, but -- and so far as getting access to the hospitals to get new accounts, get new physicians on board that's a higher hill to climb. And especially because the patients that are being treated in the same centers where COVID patients are being treated. So, we see a little bit of an undulating curve there relative to is COVID spiking, is it not spiking? But that generally sums up the situation.
Ryan Zimmerman -- BTIG -- Analyst
Okay. I appreciate that color. Maybe turning to the vitiligo trial. I think, if I recall there's an interim analysis of 33 patients. And so with the eight patients enrolled thus far, is it fair to assume that, that could be just on a similar cadence, around kind of the first quarter calendar year next year. Just maybe help us think about, kind of, when we could get it first peek at some of the data coming out of the vitiligo trial. Thank you.
Michael Perry -- President and Chief Executive Officer
Yes. More likely, Ryan, this is going to be next summer when we'd actually hit the 11 patients per group. The -- six months follow-up is going to be required. And for a split of those eight patients, we've got six in the pivotal trial and two in the feasibility trial. So, we're motoring along. We hope to beat our internal targets, but that's where we sit right now as of today.
Ryan Zimmerman -- BTIG -- Analyst
Okay. Very helpful. Thank you for taking the question.
Michael Perry -- President and Chief Executive Officer
Sure.
Operator
Thank you. Our next question comes from Kevin DeGeeter with Oppenheimer. Your line is open.
Kevin DeGeeter -- Oppenheimer -- Analyst
Hey. Great. Yes, thanks for taking my questions. Yes, maybe just two, if I may. Just -- Mike appreciate the really detailed discussions with regard to the business. Can you just talk about how you are -- what initiatives you are taking with regard to the US burn centers that do, sort of, move the needle for demand? You mentioned a number of the headwinds, but maybe you can talk a little bit about some of the things here you're adapting and particularly with regard to digital, but that maybe are working?
And sort of on that -- then kind of maybe just go into the clinical trial side, I appreciate the commentary on the challenges and the enrolling for soft tissue, just kind of walk us through what are some of the puts and takes that you would be evaluating determine whether or not -- continuation of that -- of the current study is appropriate or some other avenue to drive demand for that channel, maybe more appropriate apart from structured clinical trial?
Michael Perry -- President and Chief Executive Officer
Sure. Thanks. Thanks, Kevin. And so far as our initiatives in digital, they're very robust. We're doing a peer-to-peer video conferences and teleconferences. We're doing trainings by digital format. We are actually doing all of the elements that we would normally do face-to-face digitally. So, we're very, very engaged in that manner. That said, the effectiveness of doing things by video, by audio and not being there in-person, is -- has a lower impact. And there's no getting around that. But we're doing everything feasible with a digital format. So that answers hopefully your first question.
Your second question relative to the soft tissue trauma trial, just to give you a little bit more insight there. With the benefit of hindsight, I think we took a misstep early on and we'll own that. Our first two study sites were not really great candidates for trauma and our three enrolled patients are from a more recently initiated site. And the burns market is really more concentrated than soft tissue as you know, with 130-plus burn centers. So there -- when we start looking at the trauma centers, there are reduced number of patients at any one site. So what are we doing to address this which was your question. We're evaluating our approach here with our study steering committee, but I have to say we remain confident in the market opportunity.
And let me conclude by saying that all of our market research shows that we're close to like four times the RECELL procedures in soft tissue trauma, as compared to burns, albeit with a skew to smaller sized wounds. And this is based upon both our market research, as well as DRG data. So, we remain highly optimistic about this indication for growing our business going forward.
Kevin DeGeeter -- Oppenheimer -- Analyst
No, that all makes sense. And then maybe just one follow-on question. And this -- I appreciate that, you continue to suspend financial guidance here in the near-term. And -- but with regard to potentially reinstating guidance, and as we think about 2021, as well, is the bigger challenge there limited visibility on just the size of the current inpatient burn market, due to the impacts of COVID, or is it more just, sort of, appreciating specific customer behavior just given you some of the challenges of actually being able to -- you will get into the burn center and there's a pace at which some of these new sites ramp up. Just kind of help us, sort of, understand, kind of, what the dynamic that would need to play out would be for you to feel comfortable reinstating some sort of forward guidance.
Michael Perry -- President and Chief Executive Officer
Yes. I would say it really is primarily COVID, but is preventing us from giving firm guidance going forward. As various regions spike we end up with our reps not being able to get access to the centers and that leads to a slowdown. Also because we're still relatively early in the launch period. We have a concentrated number of sites that are providing the majority of revenues. So, we get one of those sites impacted by COVID, because they happened to be in the wrong region and that can really move the needle substantially. As we grow the business and hopefully as we continue to make not us specifically, but as COVID gets under control, more broadly will be -- we will start providing guidance going forward on revenues.
Kevin DeGeeter -- Oppenheimer -- Analyst
Great. Thank you for taking my questions.
Michael Perry -- President and Chief Executive Officer
Pleasure.
Operator
Thank you. [Operator Instructions] Our next question comes from Brooks O'Neil with Lake Street Capital. Your line is open.
Brooks O'Neil -- Lake Street Capital Markets -- Analyst
Good afternoon, Mike. How are you? I wanted to ask you a couple of quick questions. One, I was curious if the challenging environment had caused either internal or any changes in your sales and distribution organization? And then I was hoping you might provide us with a sense for the process you're going through to complete the CFO search?
Michael Perry -- President and Chief Executive Officer
So, I'll take your second question first. We've already started CFO search and so that is under way. The process is a traditional one. It's a retained search and we're, of course, looking for the best candidate. But importantly, we're going to assure this time that the candidate is located in Southern California and very close to Valencia. So, we're not going to have a repeat of what has happened to us in the past.
And so far as our challenges for our manufacturing, I think is where you were going there. We have had employees in our manufacturing facility exposed to COVID, and this has resulted in a couple instances of temporary shutdown of our manufacturing facility in Ventura, California. But for mitigation, we actually have several months of finished goods inventory stocked on both the West Coast and the East Coast remote from our manufacturing facility. So, we're well prepared to withstand even an extended shutdown should that happen. Hopefully not, but we do not anticipate any interruption to our commercial supply.
Brooks O'Neil -- Lake Street Capital Markets -- Analyst
Great. Thank you very much.
Michael Perry -- President and Chief Executive Officer
Sure.
Operator
Thank you. Our next question comes from John Hester with Bell Potter. Your line is open.
John Hester -- Bell Potter -- Analyst
Good afternoon, Mike. It's good to speak to you again. Mike, just in relation to your mix of clients -- hospital clients in the US, you've talked previously that super users and them accounting for a certain percentage of your overall solid product sells. Can you enlighten us on how that progressed in the September quarter, please?
Michael Perry -- President and Chief Executive Officer
Sure. In the September quarter, we continued with our super users the -- we have not lost anybody that we haven't had any dropouts, if you will. So, the super users have continued relative to bringing on more of what we call the super users. And those are the ones that are really utilizing the product on a consistent and regular basis for almost all patients that present with second or third degree burns that require skin grafting. We're coming close to adding some additional ones as we progress. And as we continue on that progression curve, our sales will become more regular and more predictable. And that's the trend so far.
John Hester -- Bell Potter -- Analyst
Is it possible then to estimate what sort of proportion of total procedures they'd be responsible for? I suppose what I'm getting at is [Indecipherable] COVID infection in the hospital, I have a problem there with that in that regard, what's the downside, if you like?
Michael Perry -- President and Chief Executive Officer
Well, the downside, of course, is if there is COVID infection in the hospital, there's direct competition for both burned beds and ICU beds. And that can affect our sales, as well as our business development, of course. And so far we haven't had any of our super users go down completely. Variability has definitely been there, but so far touchwood we've not lost any of our super users and our high quantity users of the RECELL System. That doesn't preclude that from happening in the future, but so far so good and fingers crossed going forward.
John Hester -- Bell Potter -- Analyst
Okay. Just a couple of following questions and just two-ones. First of all, there was discussion of a wound trial in the UK. I wonder if you could update us on that? And also with BARDA, is there any prospective dates when they might be placing an order? Clearly, it wasn't in the September quarter. Can you update us on those two issues?
Michael Perry -- President and Chief Executive Officer
Certainly. And so far as the U.K. goes, the wound trial there was in chronic wounds and that has completed and has been wind down. We're still waiting on some final data to have a final study report -- clinical study report from that site. But as you know, we're concentrating on our pivotal in vitiligo pediatrics calls and soft tissue. So chronics right now is not front end center for us.
Relative to your second question on BARDA, we will actually start stocking the VMI, the Vendor Managed Inventory, that we managed for the Federal government in December. And then we'll be booking revenues. I can pass it over to Sean to talk about how revenues will be booked for BARDA. I think, it's just going to be deferred revenues, because it's going to be spread along the -- over the duration of the BARDA contract. And it'll take us about somewhere between four to six months to fully stock the inventory and be at steady state with BARDA.
Sean Ekins -- Vice President of Finance
Yes, that's perfect, Michael.
Michael Perry -- President and Chief Executive Officer
Thanks, Sean. Does that answer your question, John?
John Hester -- Bell Potter -- Analyst
Thank you. Yes, I'm done.
Michael Perry -- President and Chief Executive Officer
Thanks.

Thank you. Our next question comes from Lyanne Harrison with Bank of America. Your line is open.
Lyanne Harrison -- Bank of America Merrill Lynch -- Analyst
Hi. Good morning. Good afternoon over there. Thank you for taking my questions. I'm interested, if we could come back to the revenue momentum. You mentioned earlier that July was the highest revenue month that AVITA had reported with 57 unique orders there. Can you give us a sense of whether you think some of those orders was restocking? Or is it really reordering for use and is it aligned with the procedures that were reported in that month?
Michael Perry -- President and Chief Executive Officer
Sure, Lyanne. We generally do not see a lot of revenue from stocking. Some of our accounts do stock a few RECELL kits to have them on hand, but we're not seeing any of our customers that are really grabbing a lot of stock that would really interrupt our revenue flow.
Lyanne Harrison -- Bank of America Merrill Lynch -- Analyst
Okay. Thank you. And then if I think about, I guess, the trend you're saying from August to today in November, are you seeing consistent increase in revenue growth sequentially month-on-month, despite the increase in COVID cases across the United States?
Michael Perry -- President and Chief Executive Officer
So, generally, I would say yes. We are seeing sequentially revenue growth month-on-month. That said, there is, of course, variability how many days of sales do we have in any one month will affect monthly sales. For example, in November, we have Thanksgiving coming. So, there are a number of days off, those types of issues. But generally the trend continues and we're going in the positive direction.
Lyanne Harrison -- Bank of America Merrill Lynch -- Analyst
Okay. Thank you. And if I could just have one follow-up, and this is probably a question for Sean. If I think about your cost structure, obviously this quarter, it was a fairly high cost structure. You mentioned that there were a few items in there as a result of redomiciliation, etc. Sean, are you able to highlight what you think in this quarter's opex might be non-recurring if we think about the remainder of financial year '21?
Sean Ekins -- Vice President of Finance
Yes. Thanks Lyanne for your question. As you noted in our opex, we did have in the current quarter a lot of one-off costs and this really related to redomiciling the company from Australia to the US, along with having our first audit, which was for a three-year period. We also had our first proxy statement and our first registration for our shelf. A lot of that will be non-recurring. Did I answer your question Lyanne?
Lyanne Harrison -- Bank of America Merrill Lynch -- Analyst
Yes. I'm just trying to understand the quantum. So, if I think about your general admin expenses of $5.5 million, what proportion of that do you think might not recur in subsequent quarters?
Sean Ekins -- Vice President of Finance
Right. My anticipation moving forward that G&A will come down. I think it'd be come down more in the range of $4 million to $4.5 million. Like I mentioned, the amount of cost that we did have in there for Q1 was rather significant. But again that was -- the charges incurred for redomiciling the company, the first US GAAP audit, which we won't have that going forward. We will have the cost for having an audit, but it will be a three-year period, which is quite substantial.
Lyanne Harrison -- Bank of America Merrill Lynch -- Analyst
Okay. So, you're thinking it's sort of $4 million and $4.5 million. And then if I look at research and development, obviously the cost there looks like it doubled, compared to the last period. Should we expect that sort of $3 million per quarter going forward, given the -- all the pivotal trials that are currently in place?
Sean Ekins -- Vice President of Finance
Yes. Yes, and I think you hit it right on the head. I mean, in the sense that our R&D did jump up in the current quarter. And this is -- just like you mentioned, it relates to our pivotal trials that we had got undergoing. My thought process moving forward and I think it'd be in the range of $3 million to $4 million, but this will be in line with the expansion of our pivotal studies.
Lyanne Harrison -- Bank of America Merrill Lynch -- Analyst
Okay. Thank you very much.
Sean Ekins -- Vice President of Finance
