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.

Participation Criteria
Eligibility Criteria
Ages Eligible for Study
Accepts Healthy Volunteers
Genders Eligible for Study
Description
Inclusion Criteria:
- Have signed informed consent to study participation. The patient may also provide consent for Future Biomedical Research (FBR). However, the patient may participate in the main study without participating in FBR.
- Female patients aged 18 years and older.
- Have locally advanced inoperable breast which cannot be treated with curative intent OR have metastatic breast cancer.

Patients initially diagnosed with hormone receptor-positive and/or HER2-positive breast cancer must have confirmation of TNBC in a tumor biopsy obtained from a local recurrence or distant metastasis site.
- Able and willing to provide a fresh tumor biopsy from a local recurrence or distant metastasis site.
- Eligible for chemotherapy with carboplatin and gemcitabine.
- WHO Performance status 0-1.
- Has received no more than two prior regimens for locally advanced or metastatic breast cancer. Prior therapy with checkpoint inhibitors (anti-PD-1, anti-PD-L1, anti-PD-L2, or anti-CTLA-4) agent is allowed.
- Have measurable disease based on RECIST 1.1 as determined by local radiology review.
- Have life expectancy ≥3 months at time of enrollment.
Demonstrate adequate organ function, within 10 days prior to the start of study treatments, as defined:
Hematological:
Absolute neutrophil count (ANC) ≥1,500/μL, Lymphocyte count >0.3 x 109/L. Platelets ≥100,000/μL, Renal Creatinine ≤1.5 × ULN OR measured creatinine clearance (GFR can also be used in place of creatinine or CrCl) ≥30 mL/min for patient with creatinine levels >1.5 × institutional ULN) Hepatic Total bilirubin ≤1.5 ×ULN ASAT and ALT ≤2.5 × ULN (≤5 × ULN for patients with liver metastases), Albumin ≥3.0 g/dL
- Women of child-bearing potential must have a negative pregnancy test at screening and agree to use acceptable methods of contraception during the study.
Exclusion Criteria:
- Previously treated with carboplatin / gemcitabine.
- Prior therapy with ALECSAT or other cellular immunotherapies.
- Is currently participating in a clinical study and receiving an investigational agent or has participated in a clinical study and received an investigational agent within 4 weeks prior to inclusion or during the trial.
- Has not recovered (to ≤Grade 1 or to baseline) from AEs due to a previously administered therapy (alopecia excluded). Prior to inclusion, the patient must have recovered adequately from any toxicity and/or complications associated with any recent procedure.
- Has an active autoimmune disease that has required systemic treatment in the past 2 years (e.g., with use of disease modifying agents, corticosteroids, or immunosuppressive drugs).

Intervention / Treatment |
---|---|
Experimental: ALECSAT
This is an exploratory single arm study. 20 patients will be included with the objective to investigate the safety, tolerability and trends of efficacy of ALECSAT for the treatment of recurrent TNBC. ALECSAT is a form of adoptive cell therapy medicinal product. ALECSAT is an abbreviation for Autologous Lymphoid Effector Cells Specific Against Tumor. ALECSAT is an autologous product that induces an immune response against a broad repertoire of CTAs expressed on cancer cells (including TNBC) leading to killing of these cells. Patients will receive standard treatment with carboplatin and gemcitabine along with 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.
