KRC-01 →External Beam Radiation Therapycisplatin →brachytherapy

KRC-01: KRC-01 is a solution that contains hydrogen peroxide 3% with sodium hyaluronate 1%. Hydrogen peroxide is the active ingredient for this radiosensitizer.

External Beam Radiation Therapy: * Target definition for EBRT will be based on 3D imaging by computed tomography, positron emission tomography with computed tomography, or MRI. * Intensity-modulated radiotherapy (IMRT) must be used. * IMRT should be given once daily Monday-Friday, 5 fractions per week.

cisplatin: * Weekly concomitant cisplatin (40 mg/m2) during EBRT * Neo-adjuvant chemotherapy or other forms of antineoplastic treatment apart from weekly concomitant cisplatin (40 mg/m2) are not allowed. * Adjuvant chemotherapy (after completion of EBRT+BT) is not allowed.

brachytherapy: * BT treatment planning will be based on 3D-image-guided BT by MRI. * Low-dose-rate, pulsed-dose-rate, or high-dose-rate BT

Study summary

This is a seamless Phase 1/2 study consisting of two components. Phase 1 component is a dose-escalation, single arm, open label study in 10 patients to evaluate the safety and tolerability of KRC 01. Phase 2 component is a randomized, open label, controlled, multi-center study in 60 patients to evaluate the preliminary antitumor effect of KRC-01 in combination with CRT.

Inclusion Criteria: * Provide written informed consent before participation. * Female subjects age 18 years or older. * Histologically diagnosed squamous cell carcinoma, adenocarcinoma or adeno-squamous cell carcinoma of the uterine cervix. * FIGO stage II and III locally advanced cervical cancer. * No evidence of metastatic disease. * At least one tumor that qualifies as a Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 tumor with tumor size \>5 cm diameter, not previously irradiated, at baseline assessed \[by magnetic resonance imaging (MRI)\] within 28 days before Day 1. * No prior chemotherapy or radiotherapy for cervical cancer. * Intention to undergo treatment including EBRT with 5 cycles of cisplatin followed by BT; to be completed within 8 weeks of its initiation. * Patients with predicted life expectancy of 3 months or more. * Target tumor is accessible for intratumoral injection. * Eastern Cooperative Oncology Group (ECOG) Performance status of 0 or 1. * Negative pregnancy test before start of CRT in women of childbearing potential and an ability/willingness to protect against pregnancy from consent and for 3 months post-RT. Exclusion Criteria: * Other primary malignancies except basal cell carcinoma of the skin. * Histologically diagnosed small cell (neuroendocrine), melanoma, clear cell and other rare variants of the classical adenocarcinoma at cervices. * Previous pelvic or abdominal radiotherapy. * Previous total or partial hysterectomy. * Combination of preoperative radiotherapy with surgery. * Patients receiving neo-adjuvant chemotherapy or non-protocol antineoplastic treatment apart from weekly cisplatin (40 mg/m2). * Anatomical location and/or extent of disease difficult to access for safe intratumoral drug injections. * Contraindications to the pelvic radiation such as inflammatory bowel disease and collagen vascular disease. * Contraindications to MRI. * Patients on anticoagulants or deranged coagulation profile. * Pregnancy or nursing. * High medical risks because of non-malignant systemic disease or with active uncontrolled infection. * Participation in another clinical trial with an investigational drug, device or biologic within the preceding 3 months, except an observational study.

Primary outcome measure(s)

  • Adverse Events — 36 month
    An AE is any untoward medical occurrence in a patient or clinical investigation subject administered a study drug that does not necessarily have a causal relationship with the treatment.
  • AEs of special interest — 36 month
    (local pain, radiation dermatitis, tumor lysis syndrome, superficial soft tissue fibrosis, vaginal stenosis, gastrointestinal/urinary AEs, and severe and medically significant bleeding (requires urgent intervention) after intratumoral injection)
  • Physical examination — at the time of Screening and at Week 6 and partial examination will be done weekly in between to document relevant changes.
    The physical examination will include: * General appearance * Head, eyes, ears, nose, and throat * Respiratory * Cardiovascular * Musculoskeletal * Abdomen * Neurologic * Extremities * Dermatologic * Lymphatic Partial examination, patient will verbally report changes since last week.
  • Tolerance — week 1 to 6
    • Number of patients who have a significant treatment delays/interruption (total duration \> 59 days)
