NCT06551142

Brief Summary

The goal of this study is to assess the safety, tolerability, clinical activity and pharmacokinetics of GSK5764227. The study will also see how the levels of GSK5764227 will change over time at different dose amounts when administered alone and in combination with other medicines like carboplatin, cisplatin, atezolizumab, pembrolizumab, durvalumab, bevacizumab, cetuximab.

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

You may qualify if:

  • Male or female participants at least 18 years of age (≥18 years)
  • Participants with histologically confirmed advanced/metastatic solid tumors, as defined per study phase and cohort, as follows:
  • o Phase 1a:
  • Participants with advanced/metastatic solid tumors.
  • For monotherapy dose escalation: participants must have progressed on or become intolerant to all available SOC therapies.
  • For combination dose escalation: participants must have received 3 or fewer prior lines of systemic anticancer therapy in the advanced/metastatic setting

  • Has adequate organ function.
  • Where available, participants should provide a formalin fixed and paraffin embedded (FFPE) tumor sample from the most recent biopsy of primary cancer or from a metastatic site for central testing. Tumor tissue is necessary for retrospective detection of B7 homolog 3 protein (B7-H3) expression by Immunohistochemistry (IHC) and other biomarker analysis.
  • At least one of the following treatment combinations/monotherapy (a, b, c, or d) is clinically indicated:
  • Atezolizumab, durvalumab, or pembrolizumab in combination with cisplatin or carboplatin (for combination 1 only).

  • Risk factors of prolonged QTc or arrhythmia events, such as heart failure, refractory hypokalemia, congenital long QT syndrome, family history of long QT syndrome, or unexplained sudden death of any direct relative under 40 years old or any concomitant medications that prolong the QT interval.
  • Left ventricular ejection fraction (LVEF) \<50%.
  • Has severe, uncontrolled or active CV disorders, serious or poorly controlled hypertension, clinically significant bleeding symptoms or serious arteriovenous thromboembolic events Any evidence of current interstitial lung disease (ILD) or pneumonitis or a prior history of ILD or non-infectious pneumonitis requiring high-dose glucocorticoids.
  • Has donated blood or blood products in excess of 500 mL (approximately 1 pint) within one month prior to first dose of study treatment.
  • Has any history of prior allogenic or autologous bone marrow transplant or other solid organ transplant.
  • Has received immunosuppressive agents within 30 days prior to first dose of study treatment (or requires long-term (30 days or longer) glucocorticoid therapy). Low-dose corticosteroids (prednisone ≤10 mg/day or equivalent) may be administered. Use of inhaled or topical steroids and prophylactic corticosteroids for procedures are permitted.
  • Participants in dehydrated condition.
  • Participant with history of nephrotic syndrome or Grade 3 proteinuria. Participants discovered to have ≥2 proteinuria on dipstick at screening should undergo a 24-hour urine collection and must demonstrate \<2 g of protein in 24 hours to be eligible.
