Breast Cancer Clinical Trial
NBTXR3 Activated by Radiotherapy for Patients With Advanced Cancers Treated With An Anti-PD-1 Therapy
The 1100 study is an open-label, Phase I, dose escalation and expansion prospective clinical study to assess the safety of intratumoral injection of NBTXR3 activated by radiotherapy in combination with anti-PD-1 therapy.
The 1100 study aims to evaluate the safety, efficacy, and tolerability of NBTXR3 activated by radiotherapy in combination with an anti-PD-1 therapy in three cohorts of patients in dose escalation and expansion parts. The Escalation Cohort 1 includes patients with LRR or R/M HNSCC with the injectable lesion in a previously irradiated field. In Escalation Cohorts 2 and 3, patients present with lung or liver metastases from any primary cancer eligible for anti-PD-1 therapy.
The Expansion cohort 1 includes patients with LRR or R/M HNSCC with the injectable lesion located either in head and neck area or in lung or liver, who are resistant to anti-PD-1 therapy. The Expansion cohort 2 includes patients with LRR or R/M HNSCC with the injectable lesion located either in head and neck area or in lung or liver, who are naive to anti-PD-1 therapy.
The Expansion Cohort 3 includes patients with inoperable NSCLC, malignant melanoma, HCC, RCC, urothelial cancer, cervical cancer or TNBC with metastases to lungs, liver or soft tissue and who are resistant to anti-PD-1 therapy.
These patients have a high unmet need and the Sponsor hypothesizes that NBTXR3 activated by radiotherapy will act synergistically with anti-PD-1 to enhance the therapeutic index of radiotherapy maximizing local effect, to overcome radio-resistance, to increase the local efficacy of immunotherapy, and to improve distant tumor control via an abscopal effect. Eligible patients will receive a single intratumoral injection of NBTXR3 subsequently activated by radiotherapy and then an approved anti-PD-1. The end of treatment visit will take place 4 weeks after the last radiotherapy fraction. Patients will be followed for long-term safety and efficacy for 2 years after the EOT visit.
Signed informed consent form
Biopsy-confirmed cancer diagnosis indicated to receive anti-PD-1 therapy:
Escalation Cohort 1: Is inoperable LRR with tumor in previously irradiated HN field that is amenable to re-irradiation or R/M HNSCC with tumor in previously irradiated HN field that is amenable to re-irradiation, or
Escalation Cohort 2: Has metastasized to the lung (including involved lymph nodes) with tumor in a previously non-irradiated lung field, or
Escalation Cohort 3: Has metastasized to the liver with tumor in a previously non-irradiated liver field
Expansion Cohorts 1 and 2: Is inoperable LRR or R/M HNSCC with at least one lesion that is amenable to irradiation within head and neck region, lung or liver
Expansion Cohort 3: Is inoperable NSCLC, malignant melanoma, HCC, RCC, urothelial cancer, cervical cancer, TNBC that has metastasized to soft tissues, lung (including mediastinal lymph nodes) or liver with at least one lesion that is amenable to irradiation
Prior anti-PD-1 exposure as follows:
Dose Escalation (all cohorts):
Has not received prior anti-PD-1 therapy (i.e., anti-PD-1 naïve), or
Has received prior anti-PD-1 therapy and meets criteria consistent with anti-PD-1 primary resistance (i.e., primary anti-PD-1 non-responder), or
Has received prior anti-PD-1 therapy and meets criteria consistent with anti-PD-1 secondary resistance (i.e., secondary anti-PD-1 non-responder)
Expansion Cohorts 1 and 3: Has received prior anti-PD-1 therapy and meets criteria consistent with anti-PD-1 primary or secondary resistance as described above
Expansion Cohort 2: Has not received prior anti-PD-1 therapy (i.e., anti-PD-1 naïve)
Has at least one tumor lesion that can be accurately measured according to RECIST 1.1. and is amenable for intratumoral injection
