What is being measured

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

  1. The amount of change in EF score in the International Erectile Function Questionnaire (IIEF) at administration of the clinical trial drug compared to the baseline value

    Descriptive statistics for the amount of change at administration of the investigational drug compared to the baseline value for each administration group are presented and analyzed by an analysis of covariance (ANCOVA)

    Erectile Function (Q1,2,3,4,5,15) : Min 6 ~ Max 30 Orgasmic Function (Q9,10) : Min 2 ~ Max 10 Sexual Desire (Q11,12) : : Min 2 ~ Max 10 Intercourse Satisfaction (Q6,7,8): : Min 3 ~ Max 15 Overall Satisfaction (Q13,14) : Min 2 ~ Max 10

    Measured: 6 month

Secondary outcomes (4)

  1. The amount of change in EF score in the International Erectile Function Questionnaire (IIEF) at administration of the clinical trial drug compared to the baseline value

    Descriptive statistics for the amount of change at administration of the investigational drug compared to the baseline value for each administration group are presented and analyzed by an analysis of covariance (ANCOVA)

    Erectile Function (Q1,2,3,4,5,15) : Min 6 ~ Max 30

    Measured: month 1, 3, 6, 9 and 12

  2. Changes in SEP Q 2 and Q 3 evaluation after administration of investigational drug compared to baseline

    Descriptive statistics for the success rate change at each time point and baseline value for each administration group are presented and analyzed by covariance analysis (ANCOVA)

    SEP 2 Were you able to insert your penis into your partner's vagina? Yes or No SEP 3 Did your erection last long enough to have successful intercourse? Yes or No

    Measured: month 1, 3, 6, 9 and 12

  3. Global Assessment Question (GAQ) evaluation after administration of investigational drugs

    The frequency and percentage of each time point by administration group are presented and analyzed by Pearson's chi-square test or Fisher's exact test

    Did Cellgram-ED improve your Erectile Function? Yes or No If so, did Cellgram-ED improve the ability to have sex? Yes or No

    Measured: month 1, 3, 6, 9 and 12

  4. Changes in Penile Doppler Sonography(PDS) level after administration of clinical trial drug compared to baseline

    For the continuous variable, descriptive statistics for each time point in each administration group and the change at each time point compared to the baseline value are presented, and analyzed by covariance analysis (ANCOVA)

    PDS results are obtained 5 min, 10 min, 15 min, 20 min, 25 min and 30 min after intracavernosal injection.

    The peak systolic velocity (PSV) is assessed as follows: >25 cm/s is considered to be normal, 20-25 cm/s is considered to be mild ED, 12-20 cm/s is considered to be moderate ED, <12 cm/s is considered to be severe arteriogenic impotence.

    The end diastolic velocity (EDV) is assessed as follows: 5 cm/s is considered to be a normal value, >5 cm/s is considered to indicate a veno-occlusive disorder.

    Measured: month 6, 12

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Cellgram-ED in people with Erectile Dysfunction, run by Pharmicell Co., Ltd. at 4 sites in South Korea.

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 13 inclusion and 16 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 9 Feb 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in South Korea. 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 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

The amount of change in EF score in the International Erectile Function Questionnaire (IIEF) at administration of the clinical trial drug compared to the baseline value (time frame: 6 month). 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 NCT04594850.

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 9 Feb 2026; AzTrials last refreshed its copy on 8 Nov 2026.
