About this study

Official title: FRAME: A Phase I Trial of the Combination of Defactinib (VS-6063) (FAK Inhibitor) and VS-6766 (RO5126766) (CH5126776) (a Dual RAF/MEK Inhibitor) in Patients With Advanced Solid Tumours

This is a multi-centre, investigator-initiated, dose escalation, Phase I trial of the combination of the FAK inhibitor, Defactinib (VS-6063), and the dual RAF/MEK inhibitor, VS-6766 (RO5126766) in patients with advanced solid tumours. VS-6766 (RO5126766) is the same compound as CH5126766.

There are two parts to this study, the dose escalation phase and the dose expansion phase. In the dose escalation phase, cohorts of 3 to 6 patients will be enrolled to determine the maximum tolerated dose (MTD) and recommended Phase II dose (RP2D). This will be followed by a dose expansion phase to further characterise the safety and tolerability and to assess the pharmacodynamic activity of the combination.

Read the detailed description

This is a multi-centre, investigator-initiated, dose escalation, Phase I trial of the combination of the FAK inhibitor, Defactinib, and the dual RAF/MEK inhibitor, VS-6766 in patients with advanced solid tumours.

There are two parts to this study, the dose escalation phase and the dose expansion phase. In the dose escalation phase, cohorts of 3 to 6 patients were enrolled to determine the maximum tolerated dose (MTD) and recommended Phase II dose (RP2D). Up to 24 patients with solid tumours were treated in the dose escalation phase of this study.

The dose escalation phase is now closed to recruitment.

This will be followed by a dose expansion phase of 86 patients to further characterise the safety and tolerability and to assess the pharmacodynamic activity of the combination.

The dose expansion phase is made up of 7 cohorts:

  • 20 patients with KRAS mutant non-small-cell lung cancer (NSCLC);
  • 7 patients with solid tumours (enriched for those with RAS mutations) willing to undergo biopsies at three time points throughout the study;
  • 20 patients with low grade serous ovarian cancer (LGSOC);
  • 10 patients with colorectal cancer (CRC);
  • 10 patients with KRAS G12V mutant NSCLC;
  • 10 patients with RAS/RAF mutant endometrioid subtype of gynaecological cancers (ovarian, endometrial, endometriosis related) and
  • 10 patients with pancreatic cancer.

The following cohorts are still open to recruitment:

  • Patients with low grade serous ovarian cancer (LGSOC);
  • Patients with KRAS G12V mutant NSCLC;
  • Patients with RAS/RAF mutant endometrioid subtype of gynaecological cancers (ovarian, endometrial, endometriosis-related) and
  • Patients with pancreatic cancer.

Patients will take the two investigational medicinal products (IMPs) as follows:

VS-6766 will be administered orally twice a week on Monday/Thursday or Tuesday/Friday at least one hour prior or two hours after a meal. The starting dose of VS-6766 will be 3.2mg once a day, twice a week and can be escalated to a maximum of 4mg once a day, twice a week.

Defactinib will be administered orally twice a day immediately after a meal. The starting dose of Defactinib will be 200mg twice daily and can be escalated to a maximum of 400mg twice daily.

A cycle length is 4 weeks (28 days). Combination dosing (VS-6766 and Defactinib) will commence on Cycle 1 Day 1 for 3 weeks followed by one week without either drug in week 4 (i.e. 3 weeks on, 1 week off).

For patients consenting to optional biopsies, a run-in dose of VS-6766 will be administered on a single day anywhere between Days -7 to Day -3 in order to facilitate pharmacodynamic (PD) biomarker analysis. Therefore, for patients undergoing biopsies the first cycle will be 5 weeks long and subsequent cycles will consist of 4 weeks.

If this schedule is not tolerated, alternative schedules may be explored following discussion by the Safety Review Committee.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • VS-6766Drug

    Also called RO5126766, CH5126766

    VS-6766 will be supplied as 0.8mg hypromellose (HPMC) capsules for oral administration. The capsule fill consists of VS-6766 and the inactive ingredients mannitol and magnesium stearate.

    VS-6766 will be administered on a twice weekly (Monday and Thursday or Tuesday and Friday) schedule for 3 weeks followed by 1 week off in every 4 week cycle, under fasting conditions (approximately 1 hour prior or 2 hours after a meal). The starting dose, based on the previous Phase I trial will be 3.2 mg given orally as a single daily dose. This can be escalated to a maximum of 4mg (as per dose escalation rules in the protocol).

  • DefactinibDrug

    Also called VS-6063

    Defactinib is formulated as a white to off-white oval tablet for oral administration and supplied in single unit dose strength of 200 mg in 120 cc (HDPE) bottles. In addition to Defactinib, formulation components include microcrystalline cellulose, lactose monohydrate, sodium starch glycolate, and magnesium stearate.

    Patients will receive Defactinib orally immediately after a meal twice daily (approximately every 12 hours) for 3 weeks followed by 1 week off in every 4 week cycle. The starting dose will be 200mg. This can be escalated to a maximum of 400mg (as per dose escalation rules in the protocol).

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing VS-6766 and Defactinib in people with NSCLC and Low Grade Serous Ovarian Cancer, run by Institute of Cancer Research, United Kingdom at 5 sites in United Kingdom.

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 26 inclusion and 24 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: under way, not looking for participants, as of the sponsor's last update on 10 Mar 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 5 sites in United Kingdom. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

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?

To establish a dose for Phase II evaluation from the maximum tolerated dose of the combination of VS-6766 and Defactinib. (time frame: 12 months). 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 NCT03875820, which also lists 2 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 10 Mar 2026.
