About this study

Official title: New Therapeutic Approaches for Tumors With RAS Gene Mutations

There is a huge variety of nucleotide substitutions that activate RAS. The search for new "universal" drugs for the RAS pathway that either interfere with RAS upregulation upstream in the signaling pathway or offset the consequences of RAS activation is important for improving therapeutic outcomes for patients with refractory malignancies.

The use of leflunomide or the combination of MEK inhibitor + hydroxychloroquine ± bevacizumab is promising for patients with mutations in RAS cascade genes who have failed all existing treatment standards.

Read the detailed description

Mutations in the RAS gene are a common cause for the development of many tumors.

It is of practical interest to study the potential efficacy of several drugs registered for the treatment of other diseases, which may also be able to affect various parts of the RAS pathway.

Leflunomide, with its active metabolite , inhibits the enzyme dihydroorotate dehydrogenase (DHODH). DHODH plays an essential role in the biosynthesis of pyrimidine, which is particularly important for the growth of RAS mutant cells.

Tumors with KRAS, NRAS, and HRAS mutations are characterized by increased MEK kinase activity. The combination of MEK inhibitor + hydroxychloroquine ± bevacizumab is able to affect MEK kinase activity by direct inhibition as well as regulation of autophagy, which is controlled in this case by the antimalarial drug hydroxychloroquine.

The use of bevacizumab is appropriate because there is evidence of its efficacy in the treatment of patients with colorectal cancer, including colorectal cancer with mutations in the KRAS gene.

What is being measured

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

  1. Objective response rate

    Objective response rate was assigned for a subject if the subject displayed either complete response (CR) or partial response (PR) per RECIST version 1.1

    Measured: at the end of 2 cycles of treatment (each cycle is 28 days)

Secondary outcomes (3)
  1. Assessment of patients' quality of life

    European Organization for the Research and Treatment of Cancer Quality of Life (EORTC QLQ-C30) is a 30-question tool used to assess the overall quality of life (QoL) in cancer participants. It consisted of 15 domains: 1 global health status (GHS) scale, 5 functional scales (Physical, role, cognitive, emotional, social), and 9 symptom scales/items (Fatigue, nausea and vomiting, pain, dyspnoea, sleep disturbance, appetite loss, constipation, diarrhea, financial impact. The EORTC QLQ-C30 GHS/QoL score ranges from 0 to 100; High score indicates better GHS/QoL. Score 0 represents: very poor physical condition and QoL. Score 100 represents: excellent overall physical condition and QoL.

    Measured: at the end of 2 cycles of treatment (each cycle is 28 days)

  2. Progression-free survival (PFS)

    Progression-free survival was defined as the time from start treatment to subsequent confirmed progression per RECIST version 1.1, or death (whichever occurred first), measured in weeks and months. For PFS assessment clinical progression (i.e., treatment discontinuation due to progression of disease) was also considered as an event.

    Measured: at the end of 2 cycles of treatment (each cycle is 28 days)

  3. Overall survival

    Overall survival was defined as the time from start treatment to subsequent death, measured in weeks and months.

    Measured: up to 3 years

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Leflunomide and The combination of MEK inhibitor + hydroxychloroquine( plaquenil) ± bevacizumab in people with RAS Mutation and Ras (Kras or Nras) Gene Mutation, run by N.N. Petrov National Medical Research Center of Oncology at 1 site 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 19 inclusion and 13 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: status not confirmed, as of the sponsor's last update on 29 Jan 2024. 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 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 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?

Results are not available in the source record.

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

Contact Evgeny Imyanitov (+79013023707, evgeny@imyanitov.spb.ru), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Objective response rate (time frame: at the end of 2 cycles of treatment (each cycle is 28 days)). 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 29 Jan 2024.
