Sponsor:

Orano Med LLC

Brief Summary:

A Phase 1 Open-Label, First-in-human, Dose Escalation and Expansion Study to Determine the Safety, Tolerability, Dosimetry, Pharmacokinetics, and Preliminary Efficacy of 212Pb-DOTAM-GRPR1 in Adult Participants with Recurrent or Metastatic GRPR-expressing Tumors

Condition or disease

Prostate Cancer Metastatic

Breast Cancer

Colon Cancer

NSCLC

Cutaneous Melanoma

Intervention/treatment

²¹²Pb-DOTAM-GRPR1

Phase

PHASE1

Detailed Description:

In this open-label, dose escalation and dose expansion single ascending dose (SAD) and multiple ascending dose (MAD) phase 1 study, adult subjects with recurrent or metastatic histologically confirmed GRPR-expressing tumors will be enrolled. In the dose escalation portion, a classic 3+3 design will be utilized for the SAD cohorts and a TITE Boin design for the MAD cohorts. Dose escalation may proceed until the recommended MAD dose is determined. Up to four (2 SAD and 2 MAD) cohorts are expected to be enrolled. Subjects will be treated with up to four cycles administered every 8 weeks. Once the recommended MAD dose is determined, the expansion cohorts of the study will commence. A dosimetry sub study will also be conducted in which participants will receive a single injection of 203Pb-DOTAM-GRPR1 with 1 week follow-up.

      • 7. Adequate renal function defined by creatinine clearance (CLCR) ≥ 60 mL/min calculated as follows: CLCR = eGFR in ml/min/1.73 m2 calculated by the Modified Diet in Renal Disease (MDRD) x participant body surface area (BSA) in m2 ÷ 1.73.
      • 8. Serum amylase and/or lipase ≤1.5 x ULN.
      • * For women of childbearing potential (WOCBP) and men with partners of childbearing potential: be willing to use highly effective methods of contraception throughout the study and for 7 months (for WOCBP, 4 months for men) after discontinuation of study intervention, as outlined in Appendix 4: Contraceptive Guidance and Collection of Pregnancy Information.
      Exclusion Criteria
      • 1. Impaired cardiac function or clinically significant cardiac disease, including any of the following
        • 1. Congestive heart failure New York Heart Association (NYHA) class II, III or IV.
        • 2. Left ventricular ejection fraction (LVEF) \<50%.
        • 3. Clinically significant arrhythmias, cardiac arrhythmias requiring antiarrhythmic therapy other than beta blockers or digoxin or digitalis compounds.

          • 8. Chronic systemic corticosteroids greater than the equivalent dose of 10 mg of prednisone/ prednisolone per day for at least 4 weeks before the first administration of 212Pb-DOTAM-GRPR1.
          • 12. Any other condition which, in the opinion of the Investigator, would preclude participation in this study.
          • 13. Participants with diabetes inadequately controlled on current treatment as judged by the Investigator or with hyperglycemia ≥ CTCAE Version 5.0 Grade 2.
