Crizotinib in Lobular Breast, Diffuse Gastric and Triple Negative Lobular Breast Cancer or CDH1-mutated Solid Tumours (ROLo)

October 17, 2025 updated by: Royal Marsden NHS Foundation Trust

Phase II Study of ROS1 Targeting With Crizotinib in Advanced E-cadherin Negative, ER Positive Lobular Breast Cancer, Diffuse Gastric Cancer, Triple Negative Lobular Breast Cancer or CDH1-mutated Solid Tumours

The purpose of this study was to find out how effective the combination of crizotinib and fulvestrant was in shrinking lobular breast cancer tumours. The investigators also assessed the side effects of the combination of crizotinib tablets and fulvestrant injections. The side effects and the doses of crizotinib and fulvestrant had already been evaluated in large clinical trials, but this was the first time these two drugs had been combined together.

Detailed Description

This clinical study was looking at whether a drug called crizotinib, which is used in some patients with lung cancer, was effective in a sub-type of breast cancer, called lobular breast cancer. As the majority of lobular breast cancers are oestrogen receptor positive (ER+ve), crizotinib was combined with a second drug, fulvestrant, to try to block tumour growth that is driven by oestrogen.

Crizotinib targets cancers with genetic changes in two genes called ALK and ROS1. Lung cancers with changes in these genes usually get smaller when treated with crizotinib. Laboratory work at the Institute of Cancer Research has shown that lobular breast cancer cells, due to a mutation in a different gene called CDH1, appear to be similarly affected by crizotinib.

Fulvestrant is an oestrogen receptor down regulator and blocks the effects of oestrogen on oestrogen receptor positive (ER+ve) breast cancer cells. Fulvestrant is an established and approved anti-hormone therapy which patients with breast cancers are receiving in the clinic. It is possible that the combination of crizotinib and an anti-oestrogen agent will shrink the tumour(s) more effectively and prevent further growth. Because fulvestrant is only effective in post-menopausal women, if participants had not yet gone through the menopause, participants needed to start (or continue to receive) a monthly injection under the skin to temporarily stop the function of the participant's ovaries to be eligible to take part in the trial.

This injection is called goserelin and had to be started at least 4 weeks before the first day of treatment on the trial.

The overall aims of this clinical study were to find out:

  • The proportion of patients whose tumour(s) shrink when they are treated with crizotinib and fulvestrant
  • The safety and tolerability of fulvestrant in combination with crizotinib, to determine that they can be given together without unacceptable side effects
  • What the drugs do to the tumours, which will help us decide which patients may benefit from this combination in the future

Assessment of E-cadherin, ER and HER2 status as per local assessment.

- Lobular breast cancer patients previously treated with at least one prior line of therapy including at least one prior line of hormone therapy for advanced disease, but no more than three prior lines of chemotherapy for advanced disease.

Gastric cancer, triple negative lobular breast cancer or CDH1-mutated solid tumour patients previously treated with at least one prior therapy for advanced disease OR relapsing within one year of completing (neo) adjuvant chemotherapy OR unsuitable for chemotherapy in the opinion of the investigator (for example patient choice not to have chemotherapy, or no suitable chemotherapy agent).

  • Measurable disease (RECIST 1.1)
  • Haematological and biochemical indices within the ranges shown in protocol. These measurements must be performed within one week (Day -7 to Day 1) before the patient goes in the trial.
  • Female patients with child-bearing potential must have a negative urine or serum pregnancy test within 7 days prior to start of trial. Both male and female patients of reproductive potential must agree to use two forms of highly effective contraception (see below) for 2 weeks before starting the study treatment, throughout the treatment period and for 90 days after discontinuation of treatment with crizotinib and 2 years after the last dose of fulvestrant.

NOTE: it is only considered highly effective if the patient is refraining from sexual intercourse during the entire period of risk associated with the study treatments

The oral contraceptive pill may be ineffective when taken with crizotinib so is not an acceptable means of contraception for female patients during this study but can be used by female partners of male patients.

  • 18 years of age or over with written (signed and dated) informed consent and be capable of co-operating with treatment and follow-up.
  • World Health Organisation (WHO) performance status 0,1 or 2
  • Estimated life expectancy of at least 3 months in the opinion of the investigator
  • Pre-/peri-menopausal ER+ lobular breast cancer patients must be willing to receive gosarelin injections every 28 days.
  • Signed and dated informed consent.
  • Patients willing and able to comply with scheduled visits, treatment plans, laboratory tests, and other procedures.

Exclusion Criteria:

  • Use of drugs that are known potent cytochrome P450 (CYP) 3A4 inhibitors or moderate or strong CYP 3A4 inducers within 12 days before the first dose of crizotinib. Us of CYP3A4 substrates with a narrow therapeutic index (such as ciclosporin) is also not permitted within 12 days prior or during the study treatment.

  • Other severe acute or chronic medical condition or psychiatric condition, recent or active suicidal ideation or behaviour, or end stage renal disease on haemodialysis, or laboratory abnormality that may increase the risk associated with study participation or investigational products administration or may interfere with the interpretation of results and, in the judgment of the Investigator, would make the patient inappropriate study entry.

  • Pregnancy or lactation.
  • Diagnosis of other malignancy within 5 years, except for adequately treated basal cell or squamous cell skin cancer, or carcinoma in situ of the breast or cervix, or low-grade (Gleason ≤6) prostate cancer.

  • Patients at risk for gastrointestinal perforation (due to e.g., history of diverticulitis).
  • Any other condition which in the Investigator's opinion would not make the patient a good candidate for the clinical trial.
