About this study
Official title: International, Multicenter, Double-blind, Randomized, Comparative Study of Efficacy and Safety of RPH-075 and Keytruda® in Patients With Unresectable or Metastatic Skin Melanoma
The goal of this double-blind, randomized study is to establish the equivalence of the efficacy, safety and immunogenicity of the drugs RPH-075 (international nonproprietary name (INN) is pembrolizumab) and Keytruda® (INN is pembrolizumab) when used in patients with unresectable or metastatic skin melanoma first or second line therapy in a monotherapy regimen.
The main task is to evaluate and compare the effectiveness of RPH-075 and Keytruda® drugs when used in patients with unresectable or metastatic skin melanoma as a 1 or 2 line therapy in monotherapy regimen, according to the objective response rate (ORR) parameter for up to 24 weeks of therapy.
Read the detailed description
This study will include the following periods:
- Screening period (before the first administration of the test drug). Before being included in the study, patients will be provided with complete information about this clinical trial, its objectives, as well as the risks associated with participating in it, as set out in the patient information sheet. After the patient signs the Informed consent Form (IF), he will be examined as part of the screening period, at the end of which the researcher will decide whether or not the patient can be randomized into the study.
- Main period (days: 1 - 168) Patients who meet the selection criteria will be randomized in a 1:1 ratio to one of the two study groups: RPH-075 and Keytruda®. Patients will receive pembrolizumab (RPH-075 or Keytruda®) in a monotherapy regimen, at a dose of 200 mg, intravenously, with a frequency of once every 3 weeks (3 weeks - 1 cycle). Therapy within the Main Study period will continue until (whichever comes first):
- 24 weeks (8 cycles, 168 days);
- disease progression (according to the Immune-Related Response Evaluation Criteria In Solid Tumors (iRECIST)/clinical progression);
- the development of phenomena of intolerable toxicity. The assessment of tumor response to the therapy at this step will be carried out every 12 weeks.
- Continued therapy period (days: 169 - 365) During the period of continued therapy, all patients will receive therapy with RPH-075, including those patients who received therapy with Keytruda® during the Main Study Period. Pembrolizumab will be administered intravenously, at a dose of 200 mg, with a frequency of once every 3 weeks. In case of significant AEs, pembrolizumab therapy may be postponed for up to 12 weeks. Therapy within the period of continued therapy will be carried out until (whichever comes first):
- a period of up to 1 year;
- before the disease progression (according to the criteria of iRECIST /clinical progression);
- the development of phenomena of intolerable toxicity. The assessment of tumor response to the therapy at this step will be carried out every 12 weeks.
- The period of further treatment (days: 366-730]) Participants in this period will be patients who, after 1 year of therapy, will have a stabilization of the disease or a tumor response to therapy. The decision to switch to this period wil be made by the researcher. If, according to the decision of the researcher, the patient will not be recommended to switch to this period, then the patient goes into the Follow-up Period. During the the period of further treatment patients will receive therapy with RPH-075 according to the same scheme as in the period of Continued therapy. Therapy within the Period will be carried out until (whichever comes first):
- a total period of up to 2 years; all examinations will be carried out within the framework of routine clinical practice;
- before the disease progression;
- the development of phenomena of intolerable toxicity. All examinations necessary for the patient, including radiation diagnostics, and concomitant therapy during the Period will be carried out within the framework of routine clinical practice and through the healthcare system, with the exception of visits where therapy will be administered (every 3 weeks). Also, during these visits, data on the AEs and occurrence of events (progression) will be collected.
- Follow-up period (FU)
For patients who will have completed their planned participation, namely:
- The period of further treatment,
- The period of continued therapy (those patients who will not be transferred during the pre-treatment Period), one follow-up visit (FU-visit) will be scheduled 28 ± 3 days after the last administration.
For patients who will complete therapy ahead of schedule (within the Main period or the Period of continued therapy), due to the progression of the disease or the development of intolerant toxicity phenomena, FU visits will be conducted with a multiplicity of 1 every 12 weeks until the Day 365 of the study.
All examinations and concomitant therapy during the Follow-up Period will be provided through the health care system (as a part of routine clinical practice), with the exception of a radiation diagnostic visit conducting to assess the response (every 12 weeks).
The total expected duration of the study is approximately 3 years. The expected duration of participation of each subject is approximately 26 months (about 2 years).

What is being measured
The primary outcome is the main question the study is designed to answer.
The objective response rate (ORR)
The objective response rate parameter (ORR) is the percentage of patients in a particular group who experienced a complete or partial tumor response to therapy during treatment, according to the criteria of Response Evaluation Criteria In Solid Tumours (RECIST) 1.1.
The complete response (CR) is the disappearance of all control lesions, confirmed by Computed tomography (CT) data for at least 4 weeks; the short diameter of any lymph node previously considered pathological (control or non-control) should be < 10 mm.
The partial response (PR) is a decrease in the sum of the diameters of the control foci by 30% or more for at least 4 weeks, compared with the initial sum of the diameters of the foci (at screening).
Measured: up to 24 weeks
Secondary outcomes (4)
The disease control rate (DCR)
DCR is the percentage of patients in a particular group who, during therapy, experienced a complete or partial tumor response to therapy, or disease stabilization, in accordance with RECIST 1.1 criteria.
Stabilization means no decrease in the sum of the diameters of control lesions sufficient to qualify as a PR, or an increase in the sum of diameters of control lesions that can be regarded as disease progression (DP), compared with the smallest sum of diameters recorded during observation.
DP is an increase in the sum of the diameters of control lesions by 20% or more relative to the smallest sum of diameters of control lesions recorded during observation (in this case, its absolute increase should be at least 5 mm), or the appearance of one or more new lesions.
Measured: up to 24 weeks
The time to response (TTR)
TTR is the time from the start of study therapy to the first documented objective tumor response to therapy, according to RECIST 1.1 criteria.
The complete response (CR) is the disappearance of all control lesions, confirmed by Computed tomography (CT) data for at least 4 weeks; the short diameter of any lymph node previously considered pathological (control or non-control) should be < 10 mm.
The partial response (PR) is a decrease in the sum of the diameters of the control foci by 30% or more for at least 4 weeks, compared with the initial sum of the diameters of the foci (at screening).
Measured: from the start of study therapy to the first tumor response to therapy, up to 24 weeks
The Duration of response (DOR)
DOR is the time from the first documented objective tumor response to therapy (according to RECIST 1.1 criteria) to disease progression according to RECIST 1.1 criteria or death from any cause.
Disease progression is an increase in the sum of the diameters of control lesions by 20% or more relative to the smallest sum of diameters of control lesions recorded during observation (in this case, its absolute increase should be at least 5 mm), or the appearance of one or more new lesions.
DP is an increase in the sum of the diameters of control lesions by 20% or more relative to the smallest sum of diameters of control lesions recorded during observation (in this case, its absolute increase should be at least 5 mm), or the appearance of one or more new lesions.
Measured: from the first tumor response to therapy to the disease progression, up to 24 weeks
The Progression-free survival (PFS)
Progression-free survival will be expressed as a level (%) of 6-month PFS. PFS is the time from randomization to disease progression according to RECIST 1.1 criteria or death from any cause. The PFS parameter assessment in this study is based on CT or Magnetic resonance imaging (MRI) data.
Measured: up to 12 months

- The period of continued therapy (those patients who will not be transferred during the pre-treatment Period), one follow-up visit (FU-visit) will be scheduled 28 ± 3 days after the last administration.
For patients who will complete therapy ahead of schedule (within the Main period or the Period of continued therapy), due to the progression of the disease or the development of intolerant toxicity phenomena, FU visits will be conducted with a multiplicity of 1 every 12 weeks until the Day 365 of the study.
All examinations and concomitant therapy during the Follow-up Period will be provided through the health care system (as a part of routine clinical practice), with the exception of a radiation diagnostic visit conducting to assess the response (every 12 weeks).
The total expected duration of the study is approximately 3 years. The expected duration of participation of each subject is approximately 26 months (about 2 years).

Key inclusion criteria (12 listed)
- A voluntarily signed and dated Informed Consent form (ICF) of the patient.
- Histologically verified (there are documented results of relevant studies, in the absence of previous studies results, verification will be performed in the central laboratory) skin melanoma (patients with uveal melanoma or melanoma of the mucous membranes are not included in the study).
- The following patient populations:
- The Eastern Cooperative Oncology Group (ECOG) score 0-2.
- The presence of measurable control tumor foci (at least 1 focus), according to the Response evaluation criteria in solid tumors (RECIST) 1.1, confirmed by the conclusion of the Blinded Independent Central Response Assessment Committee.
Key exclusion criteria (40 listed)
- Severe concomitant diseases, with life-threatening, acutely developing complications of the underlying disease (including massive pleural, pericardial or peritoneal effusion requiring aspiration, requiring intervention, pulmonary lymphangitis).
- Metastases in the central nervous system, progressing or accompanied by clinical symptoms (for example, cerebral edema, spinal cord compression) or requiring the use of glucocorticosteroids (GCS) and/or anticonvulsants in doses specified in criterion No. 6; Patients with brain metastases can be included in the study if they receive adequate therapy (surgery or radiotherapy) and are stabilized by imaging studies for at least 4 weeks before the expected date of randomization into the study.
- Concomitant diseases that are ongoing at the time of the screening examination and that increase the patient's risk of developing adverse events during the use of study therapy:
- Systemic autoimmune diseases in the active phase (including, but not limited to: systemic lupus erythematosus (SLE), Crohn's disease, ulcerative colitis (UC), systemic scleroderma, inflammatory myopathy, mixed forms of connective tissue diseases, overlap syndrome, etc.), requiring systemic therapy for 2 years before expected date of randomization into the study.
- Endocrine disorders that cannot be compensated for by regular hormone replacement therapy or other standard therapy at a constant dose for 28 days before the expected date of randomization into the study.
Eligibility is decided by the study team after screening; this overview does not establish that a patient qualifies. Full inclusion and exclusion criteria.
Interventions

Primary outcome
The objective response rate (ORR)
Time frame: up to 24 weeks
The objective response rate parameter (ORR) is the percentage of patients in a particular group who experienced a complete or partial tumor response to therapy during treatment, according to the criteria of Response Evaluation Criteria In Solid Tumours (RECIST) 1.1. The complete response (CR) is the disappearance of all control lesions, confirmed by Computed tomography (CT) data for at least 4 weeks; the short diameter of any lymph node previously considered pathological (control or non-control) should be < 10 mm. The partial response (PR) is a decrease in the sum of the diameters of the control foci by 30% or more for at least 4 weeks, compared with the initial sum of the diameters of the foci (at screening).
4 secondary outcomes
The disease control rate (DCR)
Time frame: up to 24 weeks
The time to response (TTR)
Time frame: from the start of study therapy to the first tumor response to therapy, up to 24 weeks
The Duration of response (DOR)
Time frame: from the first tumor response to therapy to the disease progression, up to 24 weeks
The Progression-free survival (PFS)
Time frame: up to 12 months
Results and safety
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing RPH-075 and Keytruda® in people with Skin Melanoma, run by R-Pharm at 36 sites in Russia.
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 12 inclusion and 40 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 15 Jul 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 36 sites in Russia. 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 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 objective response rate (ORR) (time frame: up to 24 weeks). 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 15 Jul 2026.
