Who can take part

AI summary

From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.

The trial is looking for adults with advanced or spread solid tumors, such as urothelial (bladder), lung, head and neck, cervical, stomach, esophageal or triple negative breast cancer. Standard treatments must have stopped working, not been tolerated, or been declined.

Age
18 years or older
Sex
All sexes can join
Disease stage
Incurable, locally advanced or metastatic solid tumors with measurable disease (RECIST v1.1). Dose escalation: urothelial cancer, NSCLC, HNSCC, cervical, gastric or GEJ, esophageal cancer, or TNBC. Dose optimization: urothelial cancer only.
Earlier treatment
Standard treatments are no longer effective (the disease has progressed), are not tolerated, are not medically possible, or the person declined them. People with urothelial cancer may have had up to 2 earlier MMAE-containing treatments.

Main reasons for not taking part

  • More than one earlier Nectin-4 targeted treatment
  • Peripheral neuropathy (nerve damage) worse than Grade 2
  • Current or past inflammatory skin disease, such as eczema or psoriasis, that needed or needs biologics or oral steroids
  • Not enough organ function

The registry criteria, word for word

Show all 15 criteriaShow less

Who can take part

  • Eligible tumor types: Histologic documentation of incurable, locally advanced or metastatic solid tumors for which established standard systemic therapies are no longer effective (participant must have experienced progressive disease), are not tolerated, or in the opinion of the Investigator have been considered ineligible for a particular form of standard therapy on medical grounds or have been declined by the participant, with these tumor subtypes:
  • Monotherapy and Combination Dose Escalation Arms:
  • RR la/mUC: Participants with urothelial cancer (transitional cell) with squamous differentiation or mixed cell types are eligible. Participants with upper tract disease, e.g., involving ureters, or renal pelvis, are eligible. Participants may have had up to 2 prior monomethyl auristatin E (MMAE)-containing therapies, assuming any existing peripheral neuropathy is Grade 2 or less
  • NSCLC
  • HNSCC
  • CC
  • GC and GEJ
  • EC
  • TNBC
  • Dose Optimization (Monotherapy and Combination Arms):
  • Limited to participants who have RR la/mUC,
  • Participants may have had up to 2 prior MMAE-containing therapies, assuming any existing peripheral neuropathy is Grade 2 or less 2. Participants must have measurable disease per response evaluation criteria in solid tumors (RECIST) v1.1; Adequate organ function

Who cannot take part

  • For Nectin-4 targeted agents (approved or investigational); > one prior Nectin-4 targeted agents
  • Participants with a history of, or with active, inflammatory skin disease, such as eczema, psoriasis that required or currently require biologics or oral steroids to control disease are ineligible
  • Peripheral neuropathy > Grade 2

About the trial

What the trial wants to find out

The main goal of this study is to evaluate how safe and tolerable RNDO-564 is and to identify the best dose of RNDO-564 as a single agent and in combination with pembrolizumab. The study is focused on participants with certain solid tumors that are in an advanced stage and have certain tumor makers. This will be done by measuring the side effects that participants experience and how severe they are. Additionally, the study will evaluate how RNDO-564 moves into, through, and out of the body and how the treatment affects the body.

The second goal of this study is to evaluate how well RNDO-564 works by itself or in combination with pembrolizumab at treating participants' cancer. This will be done by measuring the number of participants who respond to the treatment. The length of time where the tumor does not grow or spread will also be measured.

Participants will take RNDO-564 weekly on Days 1, 8 and 15 of a 21 day cycle. Participants in the combination arms will take RNDO-564 as described with pembrolizumab every 3 weeks.
