Modi-1 in Breast, Head and Neck, Ovarian, or Renal Cancer (ModiFY)

This is an interventional treatment trial for Triple Negative Breast Cancer Read More

Inclusion Criteria:

1. Patient either has one of the following histologically or cytologically confirmed advanced cancers not amenable to curative intent surgical resection:

   • Advanced TNBC.
   • SCCHN (oral cavity, oropharynx, hypopharynx, or larynx).
   • HGSOC including fallopian tube and primary peritoneal cancers.
   • RCC. Or the patient has histologically or cytologically confirmed SCCHN scheduled to have curative intent surgical resection.

2. Specific criteria for prior treatment of individual tumour types are as follows:

   • TNBC:

     • The patient has received available standard therapy for advanced disease (Modi-1/Modi-1v monotherapy cohorts only), or
     • Patients who stopped immunotherapy due to toxicity and with residual disease as measurable by RECIST 1.1 (Modi-1/Modi-1v monotherapy cohorts only), or
     • Patients completing a systemic treatment regimen with immunotherapy, for whom a subsequent standard of care therapy is not yet indicated or appropriate and with measurable disease in accordance with RECIST 1.1 (Modi-1/Modi-1v monotherapy cohorts only), or
     • Patients with residual disease as measurable by RECIST 1.1 on an ongoing standard of care immunotherapy regimen (Modi-1 + CPI combination cohorts only).

   • HPV (-) SCCHN:

     • The patient should have received first-line platinum containing chemotherapy (with or without radiotherapy) as treatment for advanced disease (Modi-1/Modi-1v monotherapy cohorts and Modi 1 + CPI cohorts), or
     • Patients with locally advanced or metastatic disease as measurable by RECIST 1.1 for whom all forms of platinum-based chemoradiotherapy treatment are contraindicated (Modi-1/Modi-1v monotherapy cohorts and Modi 1 + CPI cohorts), or
     • Patients completing immunotherapy therapy for whom a subsequent standard of care therapy is not yet indicated or appropriate and with measurable disease in accordance with RECIST 1.1 (Modi-1/Modi-1v monotherapy cohorts only), or
     • Patients who stopped immunotherapy due to toxicity or completion of immunotherapy but with measurable disease in accordance with RECIST 1.1 (Modi-1/Modi-1v monotherapy cohorts only), or
     • For untreated metastatic or unresectable recurrent SCCHN in adults whose tumours express PD-L1 with a combined positive score (CPS) of one or more (Modi-1 + CPI cohorts only), or
     • Patients with residual disease as measurable by RECIST 1.1 on ongoing standard of care CPI monotherapy (Modi-1 + CPI combination cohorts only).

   • SCCHN:

     o Neoadjuvant expansion cohort only; patients who are treatment-naïve and are scheduled to have tumour resection surgery, in whom a period of 6 weeks of neoadjuvant immunotherapy can be administered. Patients will only be enrolled once the Modi-1 expansion doses and a lack of increased anti-CCP antibodies (with, and without, concomitant pembrolizumab) has been established.

   • HGSOC including fallopian tube and primary peritoneal cancers:

     • The patient must be considered unsuitable for platinum chemotherapy, defined as recurrence/progression within 6 months of prior platinum-containing chemotherapy or patients in whom platinum therapy is no longer thought appropriate. Patients must have received no more than two non-platinum regimens (Modi-1/Modi-1v monotherapy cohorts), or
     • Patients completing a course of systemic therapy for whom a subsequent standard of care therapy is not yet indicated or appropriate and with measurable disease in accordance with RECIST 1.1 (Modi-1/Modi-1v monotherapy cohorts only).

   The patient must have received first-line treatment consisting of anti-angiogenic therapy. The patient must also have favourable or intermediate International Metastatic Renal-Cell Carcinoma Database Consortium (IMDC) risk score (Heng et al, 2013) (Modi1/Modi-1v monotherapy cohorts and Modi-1 + CPI cohorts), or

   • Patients who stopped immunotherapy due to toxicity and with residual disease as measurable by RECIST 1.1 (Modi-1/Modi-1v monotherapy cohorts only), or
   • Patients completing immunotherapy, for whom a subsequent standard of care therapy is not yet indicated or appropriate and with measurable disease in accordance with RECIST 1.1 (Modi-1/Modi-1v monotherapy cohorts only), or
   • Patients on active surveillance (Modi-1/Modi-1v monotherapy cohorts only), or
   • Patients eligible for standard of care nivolumab immunotherapy (Modi-1 + CPI combination cohorts only), or
   • Patients with residual disease as measurable by RECIST 1.1 on ongoing standard of care monotherapy CPI (Modi-1 + CPI combination cohorts only)
3. Patient has completed their last dose of prior cancer therapy at least 4 weeks before the first dose of study treatment.
4. Patient has been fully vaccinated against COVID-19, the last vaccination being at least 28 days prior to enrolment, except for those who have declined or are not eligible for COVID-19 vaccination.
5. Patient has recovered to Grade ≤1 (CTCAE v5.0) from the effects (excluding alopecia) of any prior therapy for their malignancies.
6. Patient has at least one measurable lesion per RECIST 1.1 criteria by computed tomography scan or magnetic resonance imaging (non-neoadjuvant cohorts).
7. Wherever possible, patients not scheduled for curative intent resection surgery should have a fresh tumour biopsy (or have an archival biopsy [obtained within the past 5 years] if obtaining a fresh biopsy is not feasible) at baseline for molecular studies, and agree to a post-treatment biopsy (at Week 25 or the end of treatment visits), if feasible. Patients in the SCCHN neoadjuvant cohort must have both a fresh pre-treatment biopsy and agree to have their resected tumour analysed.
8. Patient is male or female and at least 18 years of age.
9. Patient has a life expectancy of more than 6 months.
10. Patient has an ECOG performance status of 0 or 1.

    • Platelet count ≥100 x 10^9/L
    • Haemoglobin >90 g/L (>5.6 mmol/L)
    • Lymphocytes ≥1 x 10^9/L
