Scientific title

A Phase I/Ib Trial of the Oral Hedgehog inhibitor, LY2940680, in Combination with Weekly Paclitaxel in Patients with Platinum-Resistant, Recurrent Ovarian Cancer or Recurrent, Advanced, Solid Tumours: open-label, non-randomised, multi-centre, dose escalation trial



Study hypothesis

The available data suggest that Hh signalling plays a role in the development and growth of ovarian cancers through multiple potential mechanisms. Activation is associated with poor prognosis and may be more frequent in ovarian cancers that persist or relapse rapidly after chemotherapy. Hh inhibitors enhance the efficacy of paclitaxel in preclinical models. LY2940860 is an orally available potent inhibitor of Hh signalling and it can be given safely at biologically effective doses.

Our hypothesis is:
1. LY2940860 can be given safely by continuous oral dosing in combination with weekly intravenous paclitaxel
2. LY2940860 will increase the activity of weekly paclitaxel in women with platinum resistant ovarian cancer.

In this trial we propose to test the first hypothesis and investigate the feasibility of combining the oral Hh inhibitor, LY2940680 with weekly paclitaxel in platinum resistant, recurrent ovarian cancer. If the combination proves feasible and data from the associated translational studies are supportive, we would plan a future randomised phase II trial to test the second hypothesis further.

Ovarian cancer or recurrent, advanced, solid tumours.


Dose Escalation Phase:
Paclitaxel 80mg/m2 IV, days 1, 8 and 15 every 28 days for up to 6 cycles
LY2940680 PO Daily Days 1-28 of a 28 day cycle. Dose cohorts as below:

Dose Level LY2940680 Dose PO
-1 50mg once daily
1 100mg once daily
2 200mg once daily
3 400mg twice daily

Interim dose levels may be added depending on data from prior cohorts.
LY2940680 will be continued as a single agent after completion of chemotherapy, until disease progression or unacceptable toxicity.

Dose Expansion Phase:
Recommended combination dose as determined in the dose escalation phase.

Primary outcome measures

The primary outcome measure of the dose escalation phase is the maximum tolerated dose of LY2940680 when administered orally in combination with intravenous paclitaxel 80mg/m2 administered on day 1, 8 and 15 of a 28 day cycles based on clinical and laboratory toxicity which will be classified and graded according to CTCAE v 4.

The primary outcome of the dose expansion phase is the toxicity of the combination of LY2940680 at the recommended dose level and weekly paclitaxel (80mg/m2, IV days 1, 8 and 15 every 28 days) in recurrent platinum resistant ovarian cancer. The causality of each adverse event to LY2940680 and paclitaxel will be classified and graded according to CTCAE v 4.

Secondary outcome measures

The secondary outcome measures of the dose escalation phase are:
1. Pharmacokinetics: Cmax, T max and AUC of LY2940680, its metabolite LSN3185556 and paclitaxel
2. Response rate will be defined by RECIST 1.1
3. Progression free survival (PFS) defined as the time from first treatment dose to first appearance of progressive disease as defined by RECIST 1.1 or death from any cause. Patients still alive and without progression at the time of analysis will be censored at the last date known to be alive.
4. Overall survival will be measured from the date of first treatment dose to the date of death from any cause. Patients still alive at the time of analysis will be censored at the last date known to be alive.

The secondary outcome measures of the dose expansion phase are:
1. Dose intensity of paclitaxel is defined as the actual dose intensity as a percentage of the intended dose. Actual dose intensity is defined as the total dose (expressed as mg/m2) / length of treatment in weeks. The length of treatment will be defined as the time from day 1 of the first treatment to 4 weeks after the day 1 of the last treatment. The intended dose intensity is defined as what the patient should have received over the same period if there were no dose reductions, omissions or delays.
2. Response rate will be defined by RECIST 1.1 and defined by Combined GCIG criteria. To be evaluable for response a patient must receive at least two cycles of trial treatment and have an evaluable tumour response. All eligible patients will be included in the response rate calculation. The subset that will be assigned a response category are all patients who have received at least two cycles of treatment.
3. Progression free survival (PFS) defined as the time from first treatment dose to first appearance of progressive disease as defined by RECIST 1.1 or death from any cause. Patients still alive and without progression at the time of analysis will be censored at the last date known to be alive. Progression by CA125 criteria alone will not constitute progression.
4. Overall survival will be measured from the date of first treatment dose to the date of death from any cause. Patients still alive at the time of analysis will be censored at the last date known to be alive.

Participant inclusion criteria

Inclusion criteria of the dose escalation phase:
Histologically or cytologically confirmed advanced solid tumours refractory to standard therapy or for whom weekly paclitaxel is considered, by the investigator, to be an appropriate therapy.

Inclusion criteria of the dose expansion phase:
1. Histologically confirmed high grade serous or G3 endometrioid epithelial ovarian, fallopian tube or primary peritoneal cancer with progressive or recurrent disease (patients with carcinosarcoma are eligible but mucinous, clear cell carcinoma and grade 1 or 2 tumours are not eligible). Progression may be defined radiologically by RECIST 1.1 or by CA125 criteria in combination with clinical symptoms or signs indicative of progression. Asymptomatic rise of CA125 alone will not be defined as progressive disease. Progression of disease must have occurred within 6 months of the last dose of platinum chemotherapy.
2. ≥ 1 previous platinum based chemotherapy. This may have been given in the adjuvant setting.
3. No previous treatment with single agent weekly paclitaxel for relapsed disease. Weekly paclitaxel may have been given in the first line setting if given in combination with platinum chemotherapy.
4. No contra-indication to an image guided biopsy and tumour amenable to image guided biopsy.
5. Measurable or non-measurable disease.
6. Patients must have archival formalin-fixed paraffin-embedded tissue from their original diagnosis available for the purposes of translational research.
7. Patients with synchronous tumours e.g. ovarian and endometrial or history of prior malignancy are eligible provided that there is biopsy evidence that the disease measurable on CT and/or MRI is ovarian in origin

The following inclusion criteria will be required for all patients:
1. Written informed consent
2. Performance status ≤2 (ECOG)
3. Estimated life expectancy ≥ 3 months
4. Age ≥ 18 years
