NCT03190824

Brief Summary

Open-label, single-arm, multi-center, Phase IIa study to evaluate the efficacy, safety, and immunological response of OBP 301 in patients with unresectable/unresected metastatic melanoma. This proof of concept study will be undertaken in male and female patients with unresectable Stage III and IV melanoma. Patients with unresectable/unresected mucosal melanoma may be enrolled after consultation with the Medical Monitor.

Outcome Measures

Primary Outcomes (1)

  • Evaluate objective response rate [ORR]) to OBP-301 in both injected and noninjected lesions

    Objective response rate \[ORR\]) to OBP-301 in both injected and noninjected lesions in patients with unresectable/unresected Stage III and IV melanoma. The modification is to allow the identification of up to 10 cutaneous, subcutaneous, and/or lymph node tumor lesions and identify the lesions as target and nontarget lesions.

    up to Week 24

Secondary Outcomes (8)

  • Overall Response Rate at weeks 6, 12, 18, and 24 in the combined and individual injected lesions

    Week 24 and Week 48

  • Best Overall Response Rate at weeks 6, 12, 18, and 24 in injected and noninjected lesions

    Week 24 and Week 48

  • Time to Treatment Response from start date to end date

    Week 24 and Week 48

  • Duration of response of injected and noninjected lesions

    Week 24 and Week 48

  • Progression Free Survival at weeks 24 and 48

    Week 24 and Week 48

  • +3 more secondary outcomes

Other Outcomes (1)

  • Exploratory Analysis (optional)

    Through study completion

Study Arms (1)

OBP-301

EXPERIMENTAL

Eligible patients with unresectable Stage III and IV melanoma will receive up to 13 treatments of OBP 301 at a concentration of 1 × 1012 virus particles (VP)/mL for 24 weeks.

Drug: OBP-301

Interventions

A novel, replication-competent Ad5 based adenoviral construct that incorporates a human telomerase reverse transcriptase gene (hTERT) promoter.

Also known as: Telomelysin
OBP-301

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Histologically or cytologically confirmed malignant melanoma at Screening that is unresectable/unresected Stage IIIB, IIIC, IIID or IV. Patients with unresectable mucosal melanoma may be enrolled after consultation with the Medical Monitor.
  • Patients must have received and failed or refused available therapy for unresectable/unresected Stage III or IV melanoma.
  • Patients must be ≥ 18 years of age.
  • At least 2 cutaneous, subcutaneous and/or lymph node target lesions that are greater or equal to 1 cm in the longest diameter. One of the cutaneous, subcutaneous and/or lymph node target lesions should be designated at Screening as a noninjected target lesion. Willing to have biopsy specimens taken at Screening and at Week 6.
  • Life expectancy of ≥ 6 months from the first OBP-301 treatment.
  • Karnofsky Performance Status Scale (KPS) score of ≥ 70.
  • Adequate organ function, hematologic status, coagulation status, kidney function, and liver function as follows:
  • Absolute neutrophils \> 1,500/µL
  • Hemoglobin \> 9 g/dL, without transfusion or hematopoietic growth factor
  • Platelets \> 100,000/µL. Patients with ≤ 100,000 platelet count may be allowed into the study on a case-by-case basis after consultation with the Medical Monitor.
  • Serum creatinine \< 2 × upper limit of normal (ULN)
  • Aspartate transaminase (AST) and alanine transaminase (ALT) ≤ 2 × ULN except for patients with known liver metastases, in which case aspartate transaminase or alanine transaminase may be ≤ 5.0 × ULN
  • Total bilirubin \< 2.0 mg/dL (≤ 3.0 mg/dL for patients with known Gilbert's syndrome)
  • Serum lactate dehydrogenase (LDH) levels \< 1.5 × ULN
  • Understand the study requirements and the treatment procedures, and is willing to comply with all specified follow-up evaluations, and provides written informed consent before any study-specific tests or procedures are performed.
  • +1 more criteria

You may not qualify if:

  • Patients who have had administration of chemotherapy, target therapy, and/or immunotherapy within the last 4 weeks before the first OBP-301 administration.
  • Patients who have received other investigational medication within the last 4 weeks or a period of its 5 half-lives (whichever is shorter) before the first OBP-301 administration.
  • Patients who have had radiotherapy within the last 4 weeks before the first OBP-301 administration.
  • Effects of any other prior therapies not reverted to ≤ Grade 1 (or ≤ Grade 2 for alopecia and peripheral neuropathy).
  • Patients who have any liver metastases or visceral metastasis of ≥ 3 cm, plus evidence of progression meeting irRC 1.0 within 1 month before the first OBP-301 administration.
  • Patients with clinically active brain metastases. However, patients with previously currently stable brain metastases on medication (i.e., steroids and/or anti-seizure medications) may be enrolled after consultation with the Medical Monitor.
  • Patients known to have acute or chronic active hepatitis B virus (HBV), hepatitis C virus (HCV) or human immunodeficiency virus (HIV).
  • Patients diagnosed with additional malignancy within 3 years before the first OBP-301 administration with the exception of curatively treated basal cell carcinoma of the skin, squamous cell carcinoma of the skin and/or curatively resected in situ cervical and/or breast cancers.
  • Patients requiring chronic systemic immunosuppressive medication including pharmacologic dose of glucocorticoids or cyclosporine should be evaluated by the Medical Monitor for enrollment eligibility.
  • Uncontrolled intercurrent illness including, but not limited to, uncontrolled diabetes, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/psychological incompetence, whereby in the opinion of the Investigator the patient is assessed as being unable to provide information, consent, or comply with the study requirements and procedures.
  • Patients who are pregnant or breastfeeding, or expecting to conceive or father children within the projected timeframe of the study, starting from the time of the Screening Visit through 3 months (90 days) after the last OBP-301 administration. Females of childbearing potential must have a negative serum pregnancy test at Screening and a negative urine pregnancy test at each visit before administration of OPB-301. A female not of childbearing potential is one who has undergone bilateral oophorectomy or who has had no menses for 12 consecutive months.
