Study With Andes-1537 in Patients With Specific Types of Advanced Solid Tumor

• Status: Recruiting
• Trial end date: 2022-11-01
• Target enrollment: 0
• Participant gender: All

Summary

The study is a Phase 1 Open-label Two-stage, Safety and Tolerability Study with Cancer Type-specific Cohorts, Evaluating Subcutaneous Administration of Andes-1537 for Injection in Patients with Advanced Solid Tumors that are Refractory to Standard Therapy or For Which No Standard Therapy Is Available. Patients with unresectable solid tumors that are refractory or have failed standard therapy and are deemed non-eligible or intolerant to further therapy or for which no standard therapy is available will be included in 5 cancer type-specific parallel cohorts. The following tumor types will be evaluated for potential inclusion in each cancer type-specific cohort: gallbladder & biliary tract carcinoma; cervical carcinoma; gastric carcinoma; pancreatic carcinoma, and colorectal carcinoma.

• Phase: Phase 1
• Accepts Healthy Volunteers?: No

Criteria

Inclusion Criteria:

1. Men and women 18 years of age or older.

2. Can understand and voluntarily sign an informed consent form (ICF) prior to any study-related assessment or procedure, and are able to adhere to the study visit schedule and other protocol requirements.

3. Patients with documented pathological evidence of advanced unresectable solid tumors that are, in the opinion of their treating physician, refractory or have failed standard therapy and are deemed non-eligible or intolerant to further therapy, or for which no standard therapy is available will be enrolled in both stages of the study in the following 4 cancer type-specific cohorts:

• Gallbladder & Biliary Tract Cancer: Histologically confirmed stage 4 or unresectable stage 3b biliary tract & gallbladder adenocarcinoma with relapsed, refractory or progressive disease, who cannot tolerate or is considered resistant to platinum based chemotherapy for advanced disease such as cis-platinum and gemcitabine.

• Cervical Cancer: Histologically confirmed stages 4 or 3b cervical cancer with relapsed, refractory or progressive disease, who cannot tolerate or is considered resistant to platinum based chemotherapy for advanced disease such as cis-platinum/carboplatin and paclitaxel.

• Gastric Cancer: Histologically confirmed stage 4 or recurrent gastric adenocarcinoma with relapsed, refractory or progressive disease, who cannot tolerate or has progressed after first and second line combined chemotherapy regimens containing Epirubicin, cisplatin, fluorouracil (5-FU)/ leucovorin, oxaliplatin, irinotecan and/or docetaxel. Patients with Her2Neu positive cancer will not be eligible.

• Pancreatic Cancer: Histologically confirmed stage 4 or recurrent pancreatic adenocarcinoma with relapsed, refractory or progressive disease, who cannot tolerate or is considered resistant to combined treatment with leucovorin calcium, 5-FU, irinotecan and oxaliplatin (FOLFIRINOX) or Gemcitabine based chemotherapy, depending on age and performance status.

• Colorectal Cancer: Histologically confirmed Stage IV colorectal adenocarcinoma with relapsed, refractory, or progressive disease, who cannot tolerate or is considered resistant to combined treatment with fluoropyrimidines and/or oxaliplatin and/or irinotecan and/or Epidermal Growth Factor-1 (EGF1) inhibitors (depending on molecular profile) either as single agent or in combination therapy, depending treating oncologist´s decision. Patients with Kirsten rat sarcoma viral oncogene homolog (KRAS) - Neuroblastoma RAS Viral Oncogene Homolog (NRAS) wild type should have progressed after cetuximab or panitunumab unless contraindicated or not available.

4. Have measurable disease by RECIST.

5. Have Eastern Cooperative Oncology Group (ECOG) performance status of ≥ 1.

6. Have life expectancy ≥ 12 weeks as judged by the investigator.

7. Have adequate organ function, confirmed by the following laboratory values obtained ≤ 3 days prior to the first treatment:

• Absolute neutrophil count (ANC) ≥ 1.5 × 109/L

• Hemoglobin (Hgb) ≥ 9 g/dL

• Platelets ≥ 100 × 109/L

• Aspartate aminotransaminase (AST) and alanine aminotransaminase (ALT) ≥ 2.5 × upper limit of normal (ULN)

• Serum total bilirubin ≤ 2.0 × ULN

• Serum creatinine ≤ 1.5 × ULN (patients with Creatinine > 1,5 x ULN may be considered to participate if estimated or measured creatinine clearance ≥ 60 mL/min)

• Prothrombin time (PT), activated partial thromboplastin time (aPTT) ≤ 1.5 ULN if not on anticoagulation therapy (patients receiving anticoagulation therapy must be in the therapeutic range and stable for ≥ 4 weeks prior to study entry)

8. Patients with accessible tumor tissue, susceptible to biopsies through procedures such as colonoscopy, endoscopy, endocervical biopsy (among others), are required to provide consent for two biopsies throughout the study, to analyze tumor biomarkers. The first tumor biopsy will be performed in these patients in a timeframe of 28 days prior to the initial administration of the investigational product Andes-1537. Alternatively, pathological archived material may be used, if the biopsy was collected within a period of two months prior to initiation of treatment and with no anti-cancer treatment performed since the collection date. The second biopsy will be performed after 2 cycles (8 weeks) of treatment. If no archival material is available, and only one lesion is amenable for biopsy (and is the only target lesion), the Medical Monitor should be consulted for subject eligibility. Tumor biopsies and tumor archival material must be suitable for biomarker assessment as described in the Laboratory Manual.

9. Female patients of childbearing potential must have a negative serum pregnancy test and be using adequate contraception (defined below) prior to study entry and must agree to continue to use adequate contraception from study entry through at least 6 months after discontinuation of study drug. Note: Options for adequate contraception with a failure rate of <1% per year include: tubal ligation, male sterilization, hormonal implants, established proper use of combined oral or injected hormonal contraceptives, and certain intrauterine devices. Alternatively, two methods (e.g., two barrier methods such as a condom and cervical cap) may be combined to achieve a failure rate of <1% per year. Barrier methods must always be supplemented with the use of a spermicide. Abstinence is acceptable only if it is in line with the preferred and usual lifestyle of the patient. Periodic abstinence (e.g., calendar, ovulation, symptothermal or postovulation methods) and withdrawal are not acceptable methods of contraception. Should a female patient or a female partner of a male patient become pregnant or suspect she is pregnant while participating in the study or within 6 months following discontinuation of the study drug, the patient should inform the investigator immediately.

Exclusion Criteria:

1. Have known central nervous system metastases.

2. Have unstable angina, clinically significant cardiac arrhythmia, New York Heart Association Class 3 or 4 congestive heart failure, or prolonged QT interval corrected (QTc) wave of greater than 470 ms.

3. Receiving treatment with any medication known to produce QT prolongation within 7 days of study entry.

4. Have had prior systemic chemotherapy treatments or investigational modalities ≤ 5 half-lives (t1/2) or 4 weeks, whichever is shorter, prior to starting treatment with Andes 1537 or who have not recovered from side effects, grade 2 or greater, of such therapy (except alopecia).

5. Have had major surgery ≤ 2 weeks prior to starting treatment with Andes-1537 or who have not recovered from side effects of such surgery.

6. Are pregnant or breastfeeding.

7. Have had deep vein thrombosis (DVT) or venous thromboembolism within 6 weeks of study entry. Patients are permitted to enter the study if they are receiving anticoagulation therapy considered to be in the therapeutic range and are stable for ≥ 4 weeks prior to study entry.

8. Have active uncontrolled bleeding or a known bleeding disorder.

9. Have any serious or unstable concomitant systemic conditions that are incompatible with this clinical study, including but not limited to substance abuse, psychiatric disturbance, or uncontrolled intercurrent illness (including active infection), arterial thrombosis, or symptomatic pulmonary embolism.

10. Have a known sensitivity to any of the components of Andes-1537.

11. Are unable or unwilling to follow protocol instructions and requirements.

12. Have received more than 2 previous lines of systemic antineoplastic treatment that includes chemotherapeutic agents, target therapies, or immunotherapy considered as standard treatments for the type of tumor that the patient has.
