Personalised Neoantigen-targeting Cancer Vaccine NECVAX-NEO1 in Neoadjuvant Triple-negative Breast Cancer

Exclusion Criteria

• •Medical and surgical history, and diseases
• •1. Patients with a history of any disease, metabolic dysfunction, physical examination finding, or clinical laboratory finding that, based on the Investigator's judgement, provides a reasonable suspicion of a disease or condition that contraindicates the use of the IMP or that might affect the interpretation of the trial results or render the patient at high risk for treatment complications.
• •2. Patients with CTCAE v 5.0 Grade 3 or higher not having resolved to Grade 1 within 6 weeks before Baseline.
• •3. Patients with any significant co-morbidity which, according to the Investigator's judgement, makes patient compliance to trial conditions unlikely.
• •4. Patients with previous malignant disease (other than the tumor disease for this trial) within the last five (5) years (except adequately treated non-melanoma skin cancers and carcinoma in situ of skin, bladder, cervix, colon/rectum, breast, or prostate) unless a complete remission without further recurrence was achieved at least two (2) years prior to Screening, and the patient is deemed to have been cured with no additional therapy required or anticipated to be required.
• •5. Patients who underwent prior organ transplantation, including allogeneic stem cell transplantation.
• •6. Patients with congenital or any other immunodeficiency syndromes, or any active autoimmune disease that might deteriorate when receiving an immunostimulatory agent, except for:
• •a. Patients with vitiligo, psoriasis, alopecia not requiring immunosuppressive treatment, are eligible.
• •b. Administration of steroids through a route known to result in a minimal systemic exposure (topical, intranasal, intro-ocular, or inhalation), is acceptable.
• •7. Patients with history of uncontrolled intercurrent illness, including but not limited to uncontrolled hypertension (high blood pressure defined as BPD\>=140 mmHg or BPS \>=90 mmHg despite of combination therapy with diuretic/CCB/ACE or ARB).
• •8. Patients with a known prior hypersensitivity or contraindications to any of the IMPs or any component in its formulations or any other drug scheduled or likely to be given during the trial, including known severe hypersensitivity reactions to monoclonal antibodies (NCI CTCAE v5.0 Grade ≥ 3).
• •9. Patients with severe acute or chronic medical conditions, including
• •1. Immune colitis
• •2. Inflammatory bowel disease
• •3. History of severe vomiting or diarrhea not having resolved to Grade 1 at Baseline
• •4. Immune pneumonitis
• •5. Pulmonary fibrosis
• •6. Psychiatric conditions including recent (within the last year) or active suicidal ideation or behavior
• •7. Laboratory abnormalities that may increase the risk associated with trial participation or trial treatment administration or may interfere with the interpretation of trial results and, in the judgement of the Investigator, would make the patient inappropriate for entry into this trial.
• •10. Patients with a history of small intestine resection surgery or other major gastrointestinal surgery
• •11. Patients with active infection requiring systemic therapy with antibiotics (at both Screening and Baseline).
• •12. Patients with a known history of human immunodeficiency virus (HIV) or known acquired immunodeficiency syndrome or multi-drug resistant gram-negative bacteria.
• •13. Patients with hepatitis B virus (HBV) or hepatitis C virus (HCV) infection at Screening (positive HBV surface antigen or HCV RNA if anti-HCV antibody Screening test positive).
• •14. Patients with increased anesthesiological risk (e.g. known or predicted difficult airway) if general anesthetic is required .
• •15. Patients with increased bleeding risk (e.g. coagulopathies) and patients on anticoagulants.
• •16. Women who are pregnant or breastfeeding, or women of childbearing potential (defined as any woman who is not surgically sterile with a hysterectomy and/or bilateral oophorectomy or ≥ 12 months of amenorrhea and at least 50 years of age) not willing to use highly effective methods of birth control. Highly effective birth control is defined as follows:
• •1. combined (estrogen and progestogen containing) hormonal contraception associated with inhibition of ovulation 1: • oral
• •• intravaginal
• •• transdermal
• •2. progestogen-only hormonal contraception associated with inhibition of ovulation 1: • oral
• •• injectable
• •* implantable 2
• •3. intrauterine device (IUD) 2
• •4. intrauterine hormone-releasing system (IUS) 2
• •5. bilateral tubal occlusion 2
• •6. vasectomised partner 2,3
• •7. sexual abstinence 4
• •NOTES:
• •1. Hormonal contraception may be susceptible to interaction with the IMP, which may reduce the efficacy of the contraception method (see section 4.3)
• •2. Contraception methods that in the context of this guidance are considered to have low user dependency.
• •3. Vasectomised partner is a highly effective birth control method provided that partner is the sole sexual partner of the WOCBP trial participant and that the vasectomised partner has received medical assessment of the surgical success.
• •4. In the context of this guidance sexual abstinence is considered a highly effective method only if defined as refraining from heterosexual intercourse during the entire period of risk associated with the study treatments. The reliability of sexual abstinence needs to be evaluated in relation to the duration of the clinical trial and the preferred and usual lifestyle of the subject.
• •Males of child-bearing potential are to use a highly effective method of birth control to avoid pregnancy with any partner during the study and until the end of the Follow-up period (EoT) or 30 calendar days after the last dose of IMP.
• •17\. Patients with a known history of drug/substance abuse.
• •Prior and concomitant medication
• •18\. Patients who received any live vaccines within 30 days prior to trial treatment.
• •19\. Patients participating Treatment in any other clinical trial within 30 days before Screening.
• •20\. Patients receiving any other treatment that, in the opinion of the Investigator, might interfere with the trial
• •21\. Patients with a current drug or substance abuse.
• •22\. Patients with chronic concurrent therapy within 2 weeks before the trial treatment or expected therapy during the trial treatment period with:
• •1. Corticosteroids (except systemic corticosteroids up to 10 mg prednisolone or equivalent daily dose).
• •2. Immunosuppressive agents.
• •3. Antibiotics. Any other anticancer therapy or concurrent anticancer treatment except the neoadjuvant chemotherapy / anti-PD1 checkpoint inhibitor standard of care background therapy as per study protocol.
• •Other 23. Patients unable to understand the Protocol requirements, instructions and trial-related restrictions, the nature, scope, and possible consequences of the trial.
• •24\. Patients who are unlikely to comply with the Protocol requirements, instructions and trial-related restrictions, e.g., uncooperative attitude, inability to return for follow-up visits, and improbability of completing the trial.
• •25\. Patients with legal incapacity or limited legal capacity. 26. Patients with any condition which results in an undue risk for the patient during the trial participation according to the Investigator.
