|Condition or disease||Intervention/treatment||Phase|
|Cancer Melanoma Breast Cancer Head and Neck Cancer Lymphoma Triple-Negative Breast Cancer||Drug: LTX-315 consecutive lesions Drug: LTX-315 Drug: LTX-315 + ipilimumab Drug: LTX-315 + pembrolizumab||Phase 1|
In this phase I, open-label, multi-arm, multicentre, multi-dose dose escalation study in patients with transdermally accessible tumours; the safety, PK and efficacy of different dosing regimens of LTX-315 will be assessed.
Patients will be allocated into 4 separate (parallel) arms depending on the tumour type and the number of lesions available.
Arm A: Single lesion/sequential lesion treatment arm (LTX-315 monotherapy) (Completed) Arm B: Concurrent multiple lesion treatment arm with all tumour types (LTX-315 monotherapy) Arm C: LTX-315 combination with ipilimumab in patients with melanoma Arm D: LTX-315 combination with pembrolizumab in patients with TNBC
All patients will have at least one lesion available for injection.
Arm A: Injection of LTX-315 3 days week 1, 1 day in week 2, 3, 4, 5 and 6. Every 2 weeks starting with week 8.
Arm B (all tumours): Injection of LTX-315 2 days week 3 weeks (Day 1, 2, 8, 9, 15 and 16).
Arm C (melanoma): Injection of lTX-315 2 days week 3 weeks (Day 1, 2, 8, 9, 15 and 16) in combination with ipilimumab given in week 1 and every 3 weeks 4 cycles.
Arm D (TNBC): Injection of LTX-315 2 days week 3 weeks (Day 1, 2, 8, 9, 15 and 16) in combination with pembrolizumab given in week 1 and every 3 weeks up to 2 years.
Patients will be enrolled into a dose cohort in order of study entry. Staring with the lowest dose. A minimum of 3 patients will be enrolled into each cohort. Dose escalation determined by the Safety Review Committee and the Sponsor. The the optimal regimen will be based on the results of the Dose Escalation from the following information:
- Safety parameters including blood samples and cardiovascular effects
- Immunohistology and ultrasound confirmation of necrosis and tumour infiltrating lymphocytes
- Systemic inflammatory response
- Evidence of clinical responses
Cohorts may be utilized to:
- Evaluate different doses of LTX-315
- Explore potential modifications to the dosing schedule
- Evaluate the potential to include appropriate combination therapies with LTX-315
- Gain further information on clinical efficacy

Experimental: Arm B: LTX-315 monotherapy in multiple concurrent lesions
Patients with at least one injectable lesion and one bystander lesion will receive LTX-315 to one or more lesions:
