Summary

A phase Ib study to investigate the safety, tolerability and trends of efficacy of ALECSAT treatment as an add-on therapy to carboplatin and gemcitabine in patients with locally advanced or metastatic triple-negative breast cancer.

Detailed description

This is a phase Ib, dual-center, open-label, single-arm, clinical study to determine the safety, tolerability and trends of efficacy of ALECSAT as an add-on therapy to standard treatment with carboplatin and gemcitabine in female patients with locally advanced inoperable or metastatic TNBC, which has received no more than two prior systemic therapies for mTNBC. Study treatments will continue until any of the following occurs: disease progression is locally verified using Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST 1.1); unacceptable toxicity; intercurrent illness that necessitates discontinuation of study treatment; Investigator's decision to withdraw the patient; pregnancy; patient noncompliance with study treatment or procedure requirements; withdrawal of consent to treatment; death; end-of-treatment visit at month 18; or other administrative reasons requiring cessation of study treatment. If chemotherapy is discontinued during the study, the patient will be allowed to continue in the study on ALECSAT treatment after discontinuation of chemotherapy, based on the Investigator's judgement. In addition, if clinical assessments indicate an anti-cancer effect of ALECSAT treatment (at the discretion of the investigator) at end of study, patients will be offered to continue ALECSAT treatment after end of the study under approved named patient use. Response assessment according to RECIST v1.1 will be performed at weeks 9 (±7 days), 18 (±7 days), and 27 (±7 days) after treatment start as by local hospital standards. Imaging will continue every 9 weeks (±7 days) thereafter during the first year, independent of any treatment delays. Response assessment will be performed every 12 weeks (±7 days) after the first year. Safety will be monitored according to National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE), version 5.0 (v5.0). Patients who discontinue study treatments for reasons other than PD will continue post-treatment imaging studies for disease status follow-up as per protocol, i.e., every 9 weeks (± 7 days) and 12 weeks (± 7 days) during the first year or second year of study participation, until disease progression, start of a non-study anticancer treatment, withdrawal of consent to study participation, death, or end-of-treatment visit 18 months.

Conditions

• Triple Negative Breast Cancer
• Breast Cancer
• Metastatic Breast Cancer

Interventions

Type	Name	Description
OTHER	ALECSAT	Patients will receive concurrent chemotherapy with carboplatin/gemcitabine with cycles repeated every 3 weeks. During the loading phase, patients will receive ALECSAT at 28 days intervals at weeks 5, 9, and 13. Hereafter (the maintenance phase), ALECSAT will be administered every 12 weeks until disease progression, death, unacceptable toxicity, investigator/patient decision or EOT visit at 18 months.
