I think you are making a mistake in comparing Restasis to Lacritin/Lacriprep.  Two fundamentally different approaches to treating Dry Eye.

Lacritin is a natural human protein produced by the lacrimal and to lesser degree, meibomian glands.  This protein is key to innervating neural responses that trigger our mechanism for basal tearing, and in many cases... has been shown to promote wound healing of corneal epithelia.  This approach treats a deficiency that is ubiquitous to Sjogrens Dre Eye, one that is responsible for the cascade of the inflammatory immune response causing dry eye.  It addresses the cause.

Restasis is simply a repurposed (albeit effective) immune suppressant, Cyclosporine, which can help... but isn't nearly the same, and lacks the healing properties as what was described above.

I completely understand your cynicism, but it is not well founded in this instance.  Check out the Facebook page ( and the Lacriprep Consortium Videos in particular), talk to the Clinical Coordinators involved with the ongoing trials.  This is something that I strongly believe will become a mainstay in the arsenal for folks treating Sjogrens Dry Eye.  I say this as someone who is using it at present.  For what it is worth, is anticipated to be released at a price point comparable to Restasis.

My understanding is that Restasis is a brand name for cyclosporine.

Another possible reason for what is perceived as lack of interest, is the fact that the trials are limited to selected areas of the USA, which excluded a very large number of us who don't live near enough to a site to make it possible, or even in the same country.

Just wanted to clarify that I am a Naval Officer/Sjogrens patient with no monetary interests in Tears Solutions or development of Lacriprep; none other than being an actual Sjogrens patient, who along the rest of this community, stands to benefit from commercial licensing/release of such a first in class medication.

To further clarify; these are great people trying to help us... I can't begin to explain how accommodating, encouraging, and helpful their CMO and clinical coordinators were getting me into the trial. 

They simply forward the medication to my opthalmagist every two weeks, which is when I have a follow up assessment.  Traveling to participate is a non issue.

Tears Solutions is hardly "big pharma"; in reality they are a small Company in Charleston SC. Their CMO is a Cell Bioligist, who was part of the UVA healthcare system team (public institution no less) that studied/developed Lacritin.

UVA, a public institution, does has a stake in the drugs success. TearSolutions worked with the UVA Licensing and Ventures Group to license the patents exclusively for its company. This means UVA will benefit from royalties on any future sales of the drug.

Hopefully this answers some questions.  Again, I am only here to share my experience and encourage participation to people needing help.  Not to advertise a product.

Hi SjoggieMates,

As a Sjogren's Support Group Facilitator, I received information from a nurse in Cleveland reaching out looking for dry eye patients for the Lacriprep Study.

I will post the info I received, if for some reason it is removed, you may message me for direct contact info to the nurse in Cleveland.

Happy Holidays.
SjoDry

Hello, a new Sjogren’s and Dry Eye study is looking for patients with a confirmed diagnosis of Primary Sjogren’s and who have dry eye symptoms requiring the use of lubricating drops. Eligible patients should be 18 years of age and have no other eye diseases. If you reside near the Cleveland area please give Peggy Smith a call or email her with questions pertaining to the study. There is no cost for the study however you will be compensated for your time and expenses. If you live outside the Cleveland area please call 1-800-555-5555 to see if you qualify and receive further information. Also there is a Facebook page for the study as well. https://www.facebook.com/LacritinAndDryEye/

SjoDry and others,

The trial sites and POC info for clinical coordinators is listed on the Sjogrens Syndrome Foundation website (how I found out originally) and on the Tears Solutions webpage I shared previously.  Good luck to those reaching out; it really is was easy to participate and I believe you will find this worth your time.

Coming into this late, but wanted to thank you for sharing, Mark. How I wish I were close enough to a trial center to participate!

I have been a trial participant (for other diseases) twice, and echo Mark's encouragement to consider trial participation. (I was my ophtho's first patient on Xiidra also, and he re-evaluated me often at first, so he could send 'results' back to the company.) This is an exciting prospect in dry eye treatment, and if I were closer, I'd jump on this!

May you all find peace and comfort.

Hi,

It has been a while, thought I'd follow up and see if anyone has since been able to enroll and start a trial of this medication?

Also, thought I'd share this... folks are now interested in studying the mechanisms by which Lacritin works:  http://grantome.com/grant/NIH/R01-EY025980-01

Update:

TearsSolutions is nearing the end of the Phase I/II trial (which I actually participated in) and are looking to present their findings to the FDA in an effort to obtain "Orphan Drug" status for Lacripep.

The combined signal for efficacy and safety versus standard of care is hopefully persuasive enough for the FDA to grant this status and allow them to proceed with commercial licensing and sales coming out of the Phase II trial (because of the significant unmet need).

I read through some of the articles and with my limited knowledge I would not call this an immunological treatment for dry eye. The article speaks of dry eye as one specific symptom with no diagnostic information.

The info they give regarding the drop sounds like it addresses inflammation as a possible cause but not in relation to autoimmune or antibody involvement. Inflammation covers some territory and it sounds like they are trying to nail this down relating to quote "simple dry eye". This could be a study with collection of some good info though so we can keep our fingers crossed.

The Restasis is the cyclosporin eye drop that addresses antibodies causing inflammation resulting in destruction of the tear gland with resultant dryness. Heavens knows how many more descriptions of inflammatory dry eye will be uncovered. Mu humble take. Irish

Quite the contrary,

I can tell you from personal experience, as I participated in the trial... Restasis and Lacripep are not at all comparable.  I can tell you, as I have used Restasis and Xiidra both with no meaningful effect or trends towards improvement in Ocular Staining and Schimers testing. 

https://www.facebook.com/LacritinAndDryEye/videos/2025710027642462/

Watch the video... for lack of words, I was the mouse model.

Pay attention to what they state is observed regarding significant reduction of glandular infiltrate and overall recovery of lacrimal function. Restasis and Xiidra, unlike Lacripep, do nothing to promote wound healing, innervation of corneal epithelia cells, and improve the neurological deficits on our cornea that are causal to our lack of tears. 

I think folks here have something to be excited about.

V/r,

Mark

NIH is opening a study to define the impact of a novel therapeutic, lacripep, on maintaining/promoting functional innervation of the cornea and lacrimal gland.

http://grantome.com/grant/NIH/R01-EY025980-01

Lacripep is the active component of lacritin, a naturally occurring glycoprotein in human tears with prosecretory and mitogenic properties.  It is concluding Phase I/II trials for PSS.

"...In our preliminary studies using this model we show lacripep not only promotes tear production but also rescues innervation of the cornea and lacrimal glands, thus restoring an essential component of ocular homeostasis. Based on these studies, we propose to determine the impact of lacripep on corneal and lacrimal gland innervation during ADDE development, as well as defining mechanisms by which lacripep maintains and/or restores innervation."

"..Thus, the goals of this proposal are to: 
Aim 1) Define the neuroregenerative potential of lacripep in the cornea and lacrimal gland during dry eye disease progression; 
Aim 2) Define the mechanisms by which lacripep achieves functional innervation of the cornea during the development of dry eye; 
and Aim 3) Determine if lacripep restores tear secretion by preferentially increasing functional parasympathetic innervation of the lacrimal gland. Using a combination of imaging, biochemical and genetic approaches, the proposed studies will considerably advance our understanding of the mechanisms by which loss of corneal innervation and secretory function occurs as well as the functional significance of denervation on disease progression."

"...With 95% of dry eye patients selectively deficient in lacritin, topical use of lacripep as a natural replacement therapy for dry eye presents a tremendous opportunity to fill an enormous void in the clinical management of these patients."
