About this study

Official title: Randomized Multicenter Double-Masked Placebo-Controlled Parallel Phase I/II Study to Determine the Safety and Exploratory Efficacy of Topical Fibrinogen Depleted Human Platelet Lysate in Patients With Dry Eye Secondary to Graft vs Host Disease

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).

Read the detailed description

For patients who do not find relief from other modes of therapy, autologous serum tears have been used as an alternative therapy since the mid-1980s. Limitations such as the need for periodic blood draws, the lack of standardization in the preparation of AST and platelet-enriched plasma tears, the unknown shelf life of AST preparations, the use of non-preserved multi-dose packaging and the practical difficulties patients face in storing these products frozen or refrigerated have hindered their widespread use for treating GvHD and other forms of severe tear deficiency.

To address these shortcomings, Cambium Medical Technologies, LLC has developed a proprietary method of standardizing and manufacturing a fibrinogen-depleted standardized platelet lysate using pooled human platelet lysates (phPL) collected from qualified healthy donors (CAM-101). Because Cambium's proprietary manufacturing process depletes pooled human platelet lysates of fibrinogen (the key clotting protein in platelets), the remaining product contains enriched levels of several key nutritive and regenerative components than are normally found in non-standardized AST as well as healthy tear film.

Given the multi-factorial nature of DED, the enriched levels of numerous key nutritive components in CAM-101 may well prove to be superior to artificial tears and certain single active ingredient products which treat only one cause or contributor of dry eye (e.g., inflammation) and other forms of tear deficiency.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Participants With Ocular Treatment-related Adverse Events as Assessed by CTCAE v4.0

    To evaluate the safety and tolerability of two concentrations of CAM-101 (FD hPL 10 vol/vol % and 30 vol/vol %) topical ophthalmic solution in patients with dry eye disease (DED) secondary to graft versus host disease (GvHD) after 6 weeks (42 days) of treatment.

    The primary outcome measure:

    Percentage of patients in each dose group with ocular adverse events at Day 42

    Measured: 42 Days

  2. Number of Participants With Systemic Treatment-related Adverse Events as Assessed by CTCAE v4.0

    Number of participants with systemic treatment-related adverse events as assessed by CTCAE v4.0 To evaluate the safety and tolerability of two concentrations of CAM-101 (FD hPL 10 vol/vol % and 30 vol/vol %) topical ophthalmic solution in patients with dry eye disease (DED) secondary to graft versus host disease (GvHD) after 6 weeks (42 days) of treatment.

    The primary outcome measure:

    Percentage of patients in each dose group with systemic adverse event at Day 42

    Measured: 42 Days

  3. Number of Participants With Treatment-related Adverse Events as Assessed Change From Normal to Abnormal With Clinical Significance in Any Ocular Examination

    To evaluate the safety and tolerability of two concentrations of CAM-101 (FD hPL 10 vol/vol % and 30 vol/vol %) topical ophthalmic solution in patients with dry eye disease (DED) secondary to graft versus host disease (GvHD) after 6 weeks (42 days) of treatment.

    The primary outcome measure:

    The percentage of patients in each dose group that show a change from Normal to Abnormal with clinical significance in any ocular examination assessment at Day 42

    Measured: 42 Days

Secondary outcomes (2)
  1. Efficacy as Measured by Ocular Surface Disease Index (OSDI)

    The OSDI is a 12-item validated questionnaire used to assess the severity of dry eye disease symptoms and their impact on vision-related function. The questionnaire comprises three subscales: ocular symptoms, vision-related function, and environmental triggers. Each item is scored on a 5-point scale (0 = none of the time; 4 = all of the time). The total OSDI score is calculated using the following formula: OSDI score = (sum of score for all questions answered × 25) ÷ number of questions answered; Scores range from 0 to 100; higher scores indicate greater ocular surface disease severity and disability (0-12: normal; 13-22: mild disease; 23-32: moderate disease; >33: severe disease).

    Measured: 42 Days

  2. Efficacy as Measured by Ocular Discomfort Using the 100 Point Visual Analogue Scale (VAS) Scores

    To evaluate the preliminary efficacy of two concentrations of FD hPL (10 vol/vol % and 30 vol/vol %) to each other and to a vehicle control in the treatment of patients with DED secondary to GvHD as the result of allogeneic stem cell transplantation as measured by ocular discomfort using the 100 point visual analogue scale (VAS) scores

    Change from baseline in ocular discomfort score as measured with VAS on Day 42VAS Patients will be asked questions about their current ocular discomfort by indicating from 0 (no discomfort) to 100 (maximal discomfort)

    Measured: 42 Days

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing CAM-101 10% and CAM-101 30% in people with Dry Eye and Graft-versus-host-disease, run by Cambium Bio Limited at 6 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 11 inclusion and 22 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 12 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 12 Jun 2026). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of Participants With Ocular Treatment-related Adverse Events as Assessed by CTCAE v4.0 (time frame: 42 Days). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Jun 2026.
