Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This rollover study allows up to 40 people with KRAS G12C-mutated lung or other solid tumors who are already benefiting from opnurasib in a Novartis trial to keep receiving the drug. Participants continue their current dose of opnurasib alone or with TNO155 or trametinib. The goal is to provide ongoing treatment access and monitor long-term safety.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
opnurasib (JDQ443) alone or with TNO155 or trametinib
What this could lead to
If successful, this study shows that long-term use of opnurasib is safe and helps control KRAS G12C-mutated cancers.
What could go wrong
This is a small rollover study (40 people) with no control group, so it cannot prove the drug works better than other options. Side effects may still occur.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Key Inclusion Criteria: * Participant is currently enrolled in a pre-defined Novartis-sponsored study and is receiving opnurasib as single agent or in combination with other study treatment. * Participant has received at least 6 cycles of opnurasib in a parent study. * Participant is currently deriving clinical benefit from the study treatment, as determined by the Investigator. * Participants currently receiving treatment in one of the KontRASt studies, including those who have not experienced disease progression or who are continuing treatment beyond initial disease progression, may be eligible to enroll in the rollover study if, in the Investigator's judgment, they are expected to continue deriving clinical benefit from treatment with opnurasib (alone or in combination). Clinical benefit, as assessed by the Investigator, may be reflected by delayed disease progression, improvement in disease-related symptoms, improvement in overall quality of life, or a combination of these factors. Key Exclusion Criteria: * Participant has been permanently discontinued from opnurasib in the parent protocol for any reason other than enrollment in the CJDQ443B12105B study. * Participant is not willing to comply with the contraception requirements outlined in the exclusion criteria of the parent protocol. * Participant currently has unresolved toxicities for which opnurasib dosing has been interrupted in the parent study. * Participant has known actionable mutations, such as EGFR-sensitizing mutation, ALK rearrangement, or others, identified during the participation in the parent trial for which there are available treatment options. Other protocol-defined inclusion/exclusion criteria may apply.
