Researchers are evaluating if adding LY3537982 olomorasib to standard anti-cancer drugs improves treatment for participants with untreated advanced non-small cell lung cancer NSCLC that has a specific KRAS G12C gene change. This Phase 3 treatment study includes participants with locally advanced or metastatic NSCLC and aims to compare this combination against standard care. The study is sponsored by Eli Lilly and Company and could last up to 3 years depending on individual response and disease progression. Participants receive LY3537982 orally combined with pembrolizumab given intravenously in 21-day cycles. Some groups also receive chemotherapy drugs pemetrexed and platinum cisplatin or carboplatin intravenously. There are different dose levels and combinations being tested, including placebo groups for comparison. Treatment continues until specific discontinuation criteria are met. Parts of the study are randomized and double-blinded, with some parts non-randomized for safety lead-in. During the study, participants have regular assessments including imaging scans to measure tumor response, blood tests, and questionnaires about symptoms and quality of life. Researchers monitor side effects and survival outcomes. The main measures include progression-free survival and treatment-emergent adverse events over about one year, with overall survival followed for up to three years. Participants are closely followed throughout treatment and after to evaluate the effects and safety of the study medications.

| Factors | Olomorasib + Pembrolizumab (± Chemotherapy) | Placebo + Pembrolizumab (± Chemotherapy) | Standard of Care: Pembrolizumab (± Chemotherapy) |
|---|---|---|---|
| What it is | An investigational oral KRAS G12C inhibitor (olomorasib) given with pembrolizumab, with or without chemotherapy depending on cohort (dose‑optimization, Part A, Part B, Safety Lead‑in, Part C). | Placebo matched to olomorasib given with pembrolizumab, with or without chemotherapy depending on cohort (Part A placebo, Part B placebo arms). | Pembrolizumab with or without platinum‑based chemotherapy is the current routine first‑line treatment for advanced KRAS G12C‑mutant NSCLC. |
| Role in trial | Experimental intervention arm | Control comparator arm receiving pembrolizumab plus placebo | Established standard of care used in routine practice outside the trial |
| Purpose | Assess whether adding olomorasib to pembrolizumab (± chemo) improves outcomes over pembrolizumab‑based regimens | Provide placebo‑controlled comparison for olomorasib’s effect when added to pembrolizumab‑based regimens | Currently used as first‑line standard treatment against which investigational approaches aim to improve |
| How given or performed | Oral olomorasib combined with IV pembrolizumab; some cohorts include pemetrexed and platinum chemotherapy. | Oral placebo combined with IV pembrolizumab; some cohorts include pemetrexed and platinum chemotherapy. | IV pembrolizumab given as monotherapy or with platinum‑based chemotherapy (e.g., pemetrexed plus platinum). |
| Evidence status | Early‑phase and protocol data show promising activity but outcomes not yet established. | Serves as control within the trial; efficacy outcomes are not expected beyond pembrolizumab’s known profile. | Has demonstrated real‑world effectiveness, though overall survival remains modest (median ~13–22 months depending on PD‑L1 level). |
| Important risks | Safety profile under investigation; early data suggest manageable toxicity but combination with immunotherapy and chemotherapy may increase risks. | Safety reflects effects of standard pembrolizumab (± chemotherapy) plus potential placebo‑related effects. | Known risks include immune‑related side effects from pembrolizumab and chemotherapy‑associated toxicities; long‑term safety profile established. |
| Important limitations | Outcomes not yet reported; potential variability in efficacy across PD‑L1 defined cohorts; long‑term benefits and safety unknown. | Placebo‑controlled design may limit generalizability to standard practice where placebo is not used. | Survival outcomes remain modest, and most patients still progress within 1–2 years; unmet need persists. |
