Topical Fibrinogen-Depleted Human Platelet Lysate in Patients With Dry Eye Secondary to Graft vs. Host Disease

Completed · Phase 1/Phase 2

Conditions studied: Dry Eye, Graft-versus-host-disease, Ocular Discomfort

In brief

The purpose of this Phase 1/2 study is to compare the safety and tolerability of four times a day (QID) dosing of a non-preserved topical ocular drop formulation of 10 vol/vol % and 30 vol/vol % of FD hPL to vehicle control eye drops in patients with Dry Eye Disease (DED) secondary to Graft vs. Host Disease (GvHD).

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Male or female patients, of age 18 years (inclusive) or older at the time of signing the ICF;
• Diagnosis of DED secondary to GvHD following allogeneic hematopoietic stem cell transplantation as determined by medical history
• For females:
• Be of non-child-bearing potential. Surgically sterilized (e.g., hysterectomy or bilateral oophorectomy) for at least 6 months prior to screening or postmenopausal (postmenopausal women must have no menstrual bleeding for at least 1 year prior to screening) and menopause will be confirmed by a plasma FSH level of >40 IU/L) or
• Women of childbearing potential must be non-lactating and agree to use a highly effective acceptable form of birth control (e.g., established hormonal birth control plus a barrier method, double barrier method: intrauterine device plus condom or spermicidal gel plus condom) from 21 days prior to dosing until 7 days after dosing, and
• Women with a negative pregnancy test (β-hCG assay) in urine at screening and Day 1 predose;
• Schirmer tear test with anesthesia <7 mm/5 min in at least one eye during screening;
• Willingness and and ability to undergo, and return for, all scheduled study-related visits through Follow-up;
• Willingness and and ability to provide written Informed Consent consistent with privacy language as per national regulations (e.g., HIPAA authorization) and which signature may be obtained from the patient or legally authorized representative prior to any study-related procedures (including withdrawal of prohibited medication);
• Willingness to communicate with the Investigator and site staff and comply with all study procedures and requirements;
• Agreement not to participate in another interventional study while participating in this study.

You may not qualify if…

• Any abnormal lid anatomy or blinking function in either eye;
• Any history of other ocular disease requiring topical ocular treatment other than artificial tears and/or Restasis® (cyclosporine ophthalmic emulsion; Allergan Irvine, CA) or Xiidra® (lifitegrast, Shire, Lexington, MA). Patients currently using Restasis® or Xiidra® for conditions other than DED (e.g., allergies);
• Previous intraocular or ocular laser surgery within the past 3 months or any refractive surgery procedure within the past 6 months of the screening visit in either eye;
• Any relevant ocular anomaly interfering with the ocular surface, including active ocular herpes simplex infection, recurrent corneal erosion, symptomatic epithelial basement membrane dystrophy, mucus fishing syndrome, giant papillary conjunctivitis, post-radiation keratitis, Stevens-Johnson syndrome, corneal ulcer, abnormalities of the nasolachrymal drainage system, chemical injury, destruction of the conjunctival goblet cells or scaring, diagnosed significant anterior blepharitis and/or progressive pterygium, or any other additional condition(s) associated with or causing dry eye;
• Presence or history of any ocular disorder or condition, including ocular surgery (including palpebral and cataract surgery, trauma), infection (viral, bacterial, fungal), disease or inflammation not associated with dry eye unless disorder or disease is:
• Stable for at least 3 months before the Screening Visit; and
• As determined by the Investigator not likely to impact or possibly interfere with the interpretation of study results.
• History of ocular allergy (including seasonal conjunctivitis) or chronic conjunctivitis other than dry eye;
• Known hypersensitivity to one of the components of the study or procedural medications (e.g., fluorescein, lissamine green, Refresh Plus®);
• Inability to refrain from contact lens wear during the study, including the 2 week Run-in period;
• Anticipated temporary or permanent need for punctal plugs during the study, except if punctal plugs have been in place for at least 2 weeks prior to Screening, in which case the plugs are allowed to remain in place during the study; if plugs should fall out during the course of the study, the instance will be recorded and the plug(s) can be replaced;
• Ocular or clinically significant systemic disease (e.g., diabetes with glycemia out of range, thyroid malfunction, uncontrolled autoimmune disease) or condition(s) not stabilized within 1 month (30 days) before Screening or a condition judged by the Investigator to be incompatible or interferes with the study results;
• Inability or unwillingness to discontinue use of autologous or platelet rich plasma eye drops during the 2 week washout period and the duration of the study;
• Anticipated change in the use or dose of Restasis®, Xiidra®, or artificial tears within 14 days before Screening or during the study. If currently taking Restasis®, Xiidra®, or artificial tears, treatment(s) for DED can continue throughout the study without a change in dose. If currently using Restasis® or Xiidra® for conditions other than DED, then patient will be excluded from study. If not currently taking Restasis®, Xiidra® or artificial tears, these drugs cannot begin during the study;
• Anticipated change in the patient's use of or dosage of systemic medications that could affect tear function (e.g., antihistamines, tricyclic antidepressants, anxiolytics, antimuscarinics, beta-blocking agents, phenothiazines, tacrolimus, sirolimus, etc.) during the study. If currently taking any of these drugs, treatment(s) can continue throughout the study without a change in dose;
• Pregnancy or breast feeding at the time of study entry;
• History of clinically significant drug or food allergy;
• Positive HIV, hepatitis B or C viral test at screening;
• History, as judged by the Investigator, of drug or alcohol abuse (i.e., alcohol consumption >2 drinks/day over the last 3 months prior to screening); drug abuse is any use of illegal drugs or prescription-drug over usage or addiction;
• Taken any investigational medication and/or participated in any clinical studies within 30 days of screening;
• Any patient who, in the judgment of the Investigator, may not be able to cooperate fully with the study staff, may have difficulty following some study requirements, or is otherwise not qualified for the study;
• Any patient who is directly involved in the conduct of the protocol.
