Trial overview

Across the listed studies, Water For Injection appears as part of trial interventions, often as a comparison solution, placebo, or preparation fluid.^[1][3][8] These trials are not all about the same disease; they cover very different conditions and treatment goals.^[1][4][6]

The studies include both completed and authorised trials, showing that some research has finished and other research is still planned or ongoing.^[1][2] The trial sizes also vary a lot, from small studies with 24 people to large studies with more than 1,000 participants.^[1][8]

Conditions and patient groups

The trials involve many different patient groups, including adults with low back pain, patients with thyroid eye disease, children with peanut allergy, and women treated for cervical intraepithelial neoplasia or cervical cancer.^[1][3][5][8] Other studies look at lupus nephritis, atopic dermatitis, allergic rhinitis caused by house dust mite allergy, adenovirus infection, respiratory viral infections, neuroblastoma, and HPV-related high-grade lesions.^{[2][4][6][7][9][10][11]}

Some studies focus on adults only, such as the low back pain and allergic rhinitis trials.^[3][6] Others focus on children, such as the peanut allergy and adenovirus infection studies, which means the target population is defined by age as well as by disease.^[7][10]

Trial phases and study designs

The research includes Phase 1, Phase 2, and Phase 3 studies.^[2][1][3] Phase 1 studies are early studies that mainly check safety and dosing, while Phase 2 and Phase 3 studies look more closely at whether the treatment works and how safe it is in larger groups.^[2][1][3]

Several studies are interventional, which means the researchers give a treatment or comparison product and then measure the results.^[1][3][5] Some are randomized and placebo-controlled, meaning people are assigned by chance to different groups and one group receives a placebo, which is an inactive comparison product.^[3][6][8]

What the trials measure

The main endpoints differ by condition, but they usually measure either efficacy or safety.^[1][2][3] In the thyroid eye disease study, the main efficacy endpoint was change in proptosis, which means how far the eye bulges forward.^[1]

In the low back pain study, the main endpoint was pain improvement measured by a Visual Analog Scale, or VAS, which is a 100-mm line used to score pain from low to high.^[3] In the lupus nephritis study, the main efficacy endpoint was the proportion of patients achieving CRR at Week 37, and CRR means a complete renal response, or a strong improvement in kidney disease signs.^[4]

Some studies focus mainly on safety outcomes such as adverse events, treatment-emergent adverse events, serious adverse events, vital signs, laboratory data, and physical examination findings.^[1][5][7] Other studies measure special disease-related outcomes, such as trans epidermal water loss in atopic dermatitis, treatment response in peanut allergy, average daily TCRS in allergic rhinitis, fever resolution in adenovirus infection, viral load in saliva for respiratory infections, and recurrence of HPV-related lesions.^{[5][6][7][9][10][11]}

The role of Water For Injection in the studies

In the trial data, Water For Injection is not presented as the main treatment being tested in most studies.^[2][3][8] Instead, it is used as part of the study setup, such as a placebo, a control, or a preparation substance for injections or other test products.^[1][3][8]

For patients, this means the trial is usually testing another medicine or vaccine, while Water For Injection helps create a fair comparison or helps prepare the study product.^[1][8][11] The important question in these studies is not the water itself, but whether the main investigational treatment is safe and effective.^[1][3][6]

Key studies at a glance

One Phase 2 study in thyroid eye disease enrolled 24 patients and measured both efficacy and safety of LASN01 compared with placebo.^[1] A Phase 3 study in low back pain enrolled 216 adults and compared a fixed combination injection against diclofenac and placebo using pain scores.^[3]

In Phase 3 peanut allergy research, one trial studied 600 children aged 4 to 7 years and another studied 450 children aged 1 to 3 years, both focused on safety and desensitization outcomes.^[6][7] Another large Phase 3 study enrolled 1,220 women with cervical disease and looked at whether HPV vaccination reduced recurrence after treatment.^[8]

Other authorised studies included a Phase 1 neuroblastoma trial, a Phase 2 lupus nephritis trial, a Phase 2 atopic dermatitis study, a Phase 3 allergic rhinitis study, a Phase 3 respiratory virus study, a Phase 3 adenovirus study, and a Phase 3 HPV lesion recurrence study.^{[2][4][5][6][9][10][11]}

Patient-focused takeaways

These trials show that Water For Injection can appear in many different research settings, but the studies are really about the main treatment being tested.^[1][3][8] The people who may join a study depend on the disease, age group, and trial design.^[2][6][10]

The endpoints help researchers understand whether the treatment reduces symptoms, improves disease signs, or stays acceptably safe.^[1][3][9] Because the studies are so different, the meaning of Water For Injection in each trial depends on its role in that specific study.^[3][8]
