Item 8.01 Other Events.

On October 25, 2024, Revolution Medicines, Inc. (the “Company”) provided the following pipeline updates.

The Company reported preliminary clinical safety, tolerability and activity data for RMC-9805, its RAS(ON) oral tri-complex G12D-selective inhibitor, from its monotherapy first-in-human study (the “RMC-9805-001 study”) as of a data cutoff date of September 2, 2024 (the “Data Cutoff Date”) in patients with previously treated solid tumors harboring KRAS G12D mutations.

In the RMC-9805-001 study, a total of 179 patients treated across dose cohorts ranging from 150 mg to 1,200 mg once daily and from 300 mg to 600 mg twice daily were evaluated for safety and tolerability as of the Data Cutoff Date (Table 1). As of the Data Cutoff Date, the most common treatment-related adverse events (“TRAEs”) that were observed were gastrointestinal (“GI”)-related toxicities. TRAEs of any grade led to dose reduction in approximately 3% of patients. No TRAEs led to treatment discontinuation, and there were no treatment-related Grade 4 or 5 adverse events (“AEs”) or serious adverse events (“SAEs”) reported.

Table 1. RMC-9805-001: TRAEs for all patients treated with RMC-9805 (150 mg to 1,200 mg once daily or 300 mg to 600 mg twice daily)


	Total (n=179)
Maximum Severity of TRAEs	Grade 1		Grade 2		Grade 3		Any Grade
TRAEs occurring in ≥10% of patients, n (%)

TRAEs leading to treatment discontinuation, n (%)		0 (0%)		0 (0%)		0 (0%)		0 (0%)

Median time on treatment was 2.8 months (range: 0.1 – 8.9 months).

alanine transaminase; AST, aspartate transferase.

The Company also reported the TRAEs for 99 patients who received 1,200 mg of RMC-9805 a day (1,200 mg once daily (n=60) or 600 mg twice daily (n=39)) as of the Data Cutoff Date (Table 2). The most common TRAEs observed were GI-related toxicities and rash. TRAEs of any grade led to dose reduction in approximately 4% of these patients. No TRAEs led to treatment discontinuation in these patients, and there were no treatment-related Grade 4 or 5 AEs or SAEs reported.

Table 2. RMC-9805-001: TRAEs for patients treated with 1,200 mg a day (1,200 mg once daily (n=60) or 600 mg twice daily (n=39))

The Company also reported best percentage change in tumor size from baseline as of the Data Cutoff Date for patients with pancreatic ductal adenocarcinoma (“PDAC”) in the second-line or later (“2L+”) setting who received 1,200 mg a day (1,200 mg once daily (n=20) or 600 mg twice daily (n=20)) (Figure 1). For these patients who received a first dose of RMC-9805 at least 14 weeks prior to the Data Cutoff Date, the objective response rate (“ORR”) (including both confirmed and pending responses) was 30%, and the disease control rate (“DCR”) was 80%.

Data Cutoff Date of September 2, 2024

All treated patients with PDAC who received a first daily dose at least 14 weeks prior to Data Cutoff Date (applies to Waterfall plot and ORR table); 3 additional patients (n=2 at 1200 mg daily; n=1 at < 1200 mg daily) are not displayed on the Waterfall plot due to withdrawal of consent or clinical progression.

Among patients with a response (confirmed or unconfirmed), 55% of first response occurred after 2 months of RMC-9805 treatment (all dose levels).

CR, complete response; NE, not evaluable; PD, progressive disease; PR, partial response; PRu*, unconfirmed partial response; SD, stable disease; RECIST, Response Evaluation Criteria in Solid Tumors.

The Company believes that this preliminary safety and clinical activity data as of the Data Cutoff Date support its ongoing development of RMC-9805 as a single agent and in combination with other therapies, including its RAS(ON) multi-selective inhibitor RMC-6236.
