About this study
Official title: TOPical Imiquimod Treatment of High-grade Cervical Intraepithelial Neoplasm: a Randomized Controlled Trial.
Rationale:
Cervical Intraepithelial Neoplasia (CIN) is the premalignant condition of cervical cancer. High grade CIN (CIN 2-3) is currently treated by large loop excision of the transformation zone (LLETZ). This treatment has potential complications, such as hemorrhage, infection and preterm birth in subsequent pregnancies. For this reason, non-invasive therapies are needed. Imiquimod (an immunomodulator) was proven effective in the treatment of HPV-related vulvar intraepithelial neoplasia (VIN) and may also be effective in HPV-related CIN. [van Seters, 2012] However, the evidence is limited and study results are not consistent. [Grimm, 2012; Pachman, 2012; Lin, 2012]

Objectives:
Primary objectives: (1) to investigate the efficacy of imiquimod 5% cream for the treatment of CIN2-3 lesions and (2) to develop biomarker panels to predict clinical response to imiquimod therapy.
Secondary objectives: to assess side effects of imiquimod treatment and LLETZ, disease recurrence and quality of life.
Hypothesis:
The investigators hypothesize that imiquimod will be an effective treatment modality in approximately 50-75% of CIN lesions treated without surgical intervention.
Study design:
Single-centre randomized controlled intervention trial.
Study population:
140 women with a histological diagnosis of CIN2-3, equally divided over two study arms.
Intervention:
Patients will be randomized into one of two arms:
- Imiquimod treatment arm. Patients in this group are treated by a 16-week regime of imiquimod 5% cream.
- Standard treatment arm. LLETZ will be performed on patients in this group.
Colposcopy with diagnostic biopsies will be performed after 10 weeks for the imiquimod treatment arm. In case progressive disease, the treatment will be ended and appropriate surgical excision will be performed. Treatment efficacy will be evaluated after 20 weeks, by colposcopy with diagnostic biopsies. A histological biomarker panel will be developed, consisting of markers representing both host and viral factors.
Main study parameters/endpoints:
The primary endpoint of the study is regression-or-not of CIN2-3, defined as CIN1 or less at the colposcopy at 20 weeks for the imiquimod arm and PAP 1 cytology at 6 months for the LLETZ group.
Read the detailed description
The treatment period was set at 20 weeks, in order to realize adequate treatment efficacy of imiquimod, while minimizing the risk of progression of cervical dysplasia to invasive disease in the conservative treatment group. Based on the available literature on the natural history of CIN and several studies on cervical dysplasia that included a conservative treatment group, the risk of disease progression within the treatment period of 20 weeks is estimated to be marginal. Approximately 30% of high-grade CIN progresses to cervical cancer. [Peto, 2004; McCredie, 2008]. This is believed to be a slow process, which can take many years. The annual risk of progression of CIN 3 to invasive cervical cancer is estimated to be less than 1%.[Canfell, 2004]. Ten studies were identified in which a total of 637 patients with high grade CIN were included either as a control group, receiving conservative treatment during 6 weeks to 15 months, or followed during the period between diagnosis and LLETZ.[Grimm, 2012, Follen, 2001; Meyskens, 1994; Keefe, 2001; Alvarez, 2003; Garcia, 2004; Van Pachterbeke, 2009; Kaufmann, 2007; Trimble 2005; Munk, 2012] Three cases of invasive disease were identified: all occured in the same study after 16 weeks of conservative treatment. Other studies showed no progression to invasive disease. One case of progression was reported with undefined disease grade and follow-up term. The possibility of invasive disease already present at the initial colposcopy (biopsy error) cannot be excluded. Based on these results, the investigators selected a treatment period of 20 weeks, with a control colposcopy with diagnostic biopsies after ten weeks.
The current study protocol includes a substantial amendment to the original study protocol, which consisted of three study arms: imiquimod treatment arm, LLETZ treatment arm and an observational arm. The purpose of the observational arm was to assess spontaneous regression of high-grade CIN and to develop a prognostic biomarker panel to predict spontaneous regression of high-grade CIN. Patients in the observational arm underwent no treatment for a period of maximum 20 weeks. Histological assessment of disease development was performed after 10 and 20 weeks by colposcopy with diagnostic biopsies. Inclusion of patients into the study was hampered by the observational arm: patients declined the study because they wished to be treated, rather than undergo observational management. The observational arm was removed from the study.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
ImiquimodDrug
Also called Imiquimod, Aldara.
Imiquimod 5% cream will be administered in a vaginal applicator, containing 12,5 mg of imiquimod (one sachet). The cream will be self-administered three times per week, by use of a vaginal applicator.
LLETZProcedure or surgery
Also called Loop excision
Standard treatment consists of a LLETZ procedure, in which excision of the transformation zone and macroscopic lesions is performed by a monopolar loop electrode, under local anaesthesia. The excision is usually performed in two or three steps, depending on the size of the lesions.
| Study group | Role | What they receive |
|---|---|---|
| Imiquimod treatment arm | Experimental | Patients in this group will be treated with imiquimod during 16 weeks. Colposcopy with diagnostic biopsies will be performed after 10 weeks. In case of progressive disease, the treatment will be ended and appropriate surgical excision will be performed. Treatment efficacy will be evaluated after 20 weeks, by colposcopy with diagnostic biopsies. Receives: Drug: Imiquimod |
| Standard treatment arm | Active comparator | Large loop excision of the transformation zone (LLETZ) will be performed in this group, as standard treatment. Receives: Procedure: LLETZ |

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Rationale:
Cervical Intraepithelial Neoplasia (CIN) is the premalignant condition of cervical cancer. High grade CIN (CIN 2-3) is currently treated by large loop excision of the transformation zone (LLETZ). This treatment has potential complications, such as hemorrhage, infection and preterm birth in subsequent pregnancies. For this reason, non-invasive therapies are needed. Imiquimod (an immunomodulator) was proven effective in the treatment of HPV-related vulvar intraepithelial neoplasia (VIN) and may also be effective in HPV-related CIN. [van Seters, 2012] However, the evidence is limited and study results are not consistent. [Grimm, 2012; Pachman, 2012; Lin, 2012]
Objectives:
Primary objectives: (1) to investigate the efficacy of imiquimod 5% cream for the treatment of CIN2-3 lesions and (2) to develop biomarker panels to predict clinical response to imiquimod therapy.
Secondary objectives: to assess side effects of imiquimod treatment and LLETZ, disease recurrence and quality of life.
Hypothesis:
The investigators hypothesize that imiquimod will be an effective treatment modality in approximately 50-75% of CIN lesions treated without surgical intervention.
Study design:
Single-centre randomized controlled intervention trial.
Study population:
140 women with a histological diagnosis of CIN2-3, equally divided over two study arms.
Intervention:
Patients will be randomized into one of two arms:
- Imiquimod treatment arm. Patients in this group are treated by a 16-week regime of imiquimod 5% cream.
- Standard treatment arm. LLETZ will be performed on patients in this group.
Colposcopy with diagnostic biopsies will be performed after 10 weeks for the imiquimod treatment arm. In case progressive disease, the treatment will be ended and appropriate surgical excision will be performed. Treatment efficacy will be evaluated after 20 weeks, by colposcopy with diagnostic biopsies. A histological biomarker panel will be developed, consisting of markers representing both host and viral factors.
Main study parameters/endpoints:
The primary endpoint of the study is regression-or-not of CIN2-3, defined as CIN1 or less at the colposcopy at 20 weeks for the imiquimod arm and PAP 1 cytology at 6 months for the LLETZ group.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Imiquimod and LLETZ in people with Cervical Intraepithelial Neoplasia, run by Maastricht University Medical Center at 1 site in Netherlands.
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 2 inclusion and 4 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: stopped early, as of the sponsor's last update on 15 Aug 2018. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Netherlands. 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. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study was stopped early (reason given: Insufficient number of participants.). Results are not available in the source record.
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?
Treatment efficacy: histological disease regression (time frame: 20 weeks). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02329171, which also lists 18 linked publications.
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 15 Aug 2018.
