Breast Cancer Clinical Trial

Study of the Safety, Pharmacokinetics and Efficacy of EDO-S101, in Patients With Advanced Solid Tumors

Summary

Tinostamustine (EDO-S101) is a new chemical entity, an AK-DAC (a first-in-class alkylating deacetylase inhibiting molecule), that in pre-clinical studies has been shown to simultaneously improve access to the DNA strands within cancer cells, break them and block damage repair. This Phase 1/2 study will enroll patients with various advanced solid tumors.

Full Description

The study consists of 2 phases:

Phase 1: Dose Escalation until MAD
Phase 2: Evaluation of Toxicity and Response Rate in Selected Solid Tumor Cohorts

The study is designed as an open label, Phase 1/2 trial of single agent EDO-S101. The Phase 1 portion of the study is designed to define the MTD by evaluating toxicities during dose escalation until MAD. The Phase 2 portion of the study is designed to evaluate ORR and SD that persists for at least 4 months of the RP2D.

If male, must be sterile or willing to abstain from sexual intercourse or employ a barrier method of contraception during the study treatment and for at least 6 months following last treatment.

General Phase 1 and 2 Exclusion Criteria:

Patients with primary central nervous system (CNS) cancer.
Patients with QTc interval >450 msec for male and >470 msec for female.
Patients who are on treatment with drugs known to prolong the QT/QTc interval.
Patients who are being treated with Valproic Acid for any of its indication (epilepsy, mood disorder) must be excluded or must stop using the medication.
Any serious medical condition that interferes with adherence to study procedures.
Prior history of solid tumor malignancy diagnosed within the last three (3) years of study enrollment excluding adequately treated basal cell carcinoma of the skin, squamous cell carcinoma of the skin, or in situ cervical cancer, in situ breast cancer, in situ prostate cancer (patients must have shown no evidence of active disease for 2 years prior to enrollment)
Pregnant or breast feeding females.
New York Heart Association (NYHA) stage III/IV congestive heart failure, arrhythmias not adequately controlled, or other significant co-morbidities [e.g. active infection requiring systemic therapy, history of human immunodeficiency virus (HIV) infection, or active Hepatitis B or Hepatitis C].
Use of other investigational agents within 30 days or 5 half-lives prior to the first dose of study drug. As long as patient has recovered from any related toxicities ≥ Grade 1.
Steroid treatment within seven (7) days prior to study treatment. Patients that require intermittent use of bronchodilators, topical steroids or local steroid injections will not be excluded from the study. Patients who have been stabilized to 10 mg Prednisolone PO QD (or equivalent), daily (or less) at least seven (7) days prior to study drug administration are allowed.

Phase 2 Tumor-specific Eligibility Criteria

Phase 2 patients must meet the cohort-specific inclusion/exclusion criteria in addition to the general inclusion/exclusion criteria for Phase 1 and Phase 2 study listed above.

Cohort 1: Patient Population: Relapsed/Refractory SCLC

Histologically or cytologically confirmed limited or extensive disease stage of SCLC. The disease should be progressing during or relapsing after the previous treatment.
At least one line of prior combination and no other standard therapy with proven clinical benefit is available or recommended based on the investigator's individual risk-benefit assessment for the patient.
At least 3 weeks or 5 half-lives, whichever is shorter, should have elapsed since prior treatment as long as the patient recovered from any related toxicities to ≤ Grade 1 (or ≤ Grade 2 for any symptomatic neuropathy or endocrinopathies).
Prior radiotherapy is acceptable provided the patient has recovered from any radiotherapy related acute toxicities.
Presence of measurable disease as defined by the RECIST version 1.1

Cohort 2: Patient Population: Relapsed/Refractory Soft Tissue Sarcoma

Histologically confirmed diagnosis of advanced, unresectable, or metastatic soft tissue sarcoma not amenable to curative treatment with surgery or radiotherapy excluding: neuroblastoma, embryonal rhabdomyosarcoma, or Kaposi sarcoma.
Must have received at least one prior line chemotherapy regimen and no other standard therapy with proven clinical benefit is available or recommended based on the investigator's individual risk-benefit assessment for the patient. For GIST-patients: must have received at least two lines of tyrosine kinase inhibitors or do not respond to or for which tyrosine kinase inhibitor therapy is not suitable.
The disease should be progressing/relapsed during or after the previous treatment. At least 3 weeks should have elapsed since prior chemotherapy or 5 half-lives, whichever is shorter, as long as the patient recovered from any related toxicities to ≤ Grade 1 (or ≤ Grade 2 for any symptomatic neuropathy or endocrinopathies).
Presence of measurable disease as defined by RECIST version 1.1

Cohort 3: Patient Population: Relapsed/Refractory Triple Negative Breast Cancer

Histologically or cytologically confirmed locally advanced or metastatic Triple Negative Breast Cancer. Proven HER2 negative by immunohistochemistry (IHC) or in situ hybridization (ISH) per ASCO-CAP guidelines.
Must have received at least one line of chemotherapy and no other standard therapy with proven clinical benefit is available or recommended based on the investigator's individual risk-benefit assessment for the patient. At least 3 weeks should have elapsed since prior chemotherapy or 5 half-lives, whichever is shorter, as long as the patient recovered from acute toxicity of previous therapies to ≤ grade 1 (or ≤ Grade 2 for any symptomatic neuropathy or endocrinopathies).
Prior radiotherapy is acceptable provided it was applied within 4 four weeks (2 weeks for palliative, limited field radiation therapy) prior to starting treatment on this trial and the patient recovered from any radiotherapy related acute toxicities.
The disease should be progressing/relapsed during or after the previous treatment.
Presence of measurable disease as defined by RECIST version 1.1

Cohort 4: Patient Population: Relapsed/Refractory Ovarian Cancer

Histologically or cytologically confirmed advanced ovarian cancer: epithelial ovarian cancer, primary peritoneal cancer or fallopian tube cancer (excluding borderline ovarian cancer) that is resistant or refractory to platinum therapy and no other standard therapy with proven clinical benefit is available or recommended based on the investigator's individual risk-benefit assessment for the patient.

Platinum-resistant ovarian cancer is defined as disease that responded to primary platinum therapy and then progressed within 6 months or disease that progressed during or within six months of completing a subsequent platinum therapy.
Primary platinum refractory disease is defined as disease that has not responded to a platinum-based regimen or experienced disease recurrence within 3 months of completing a first-line platinum-based regimen.

At least 3 weeks should have elapsed since prior chemotherapy or 5 half-lives, whichever is shorter, as long as the patient recovered from acute toxicity of previous therapies to ≤ Grade 1 (or ≤ Grade 2 for any symptomatic neuropathy or endocrinopathies).
Presence of measurable disease as defined by RECIST version 1.1

Cohort 5: Relapsed/Refractory Endometrial Cancer

Histologically or cytologically confirmed locally advanced or metastatic endometrial cancer.

At least 3 weeks should have elapsed since prior chemotherapy or 5 half-lives, whichever is shorter, as long as the patient recovered from acute toxicity of previous therapies to ≤ Grade 1 (or ≤ Grade 2 for any symptomatic neuropathy or endocrinopathies).
