Identifiers on file: NDC 85219-101, application NDA220910, label effective 20260827. This page reproduces the FDA-approved label text so you can check what a product is, who makes it and how it is supplied before discussing it with a pharmacist or prescriber.

Across FDA labelling, products containing DARAXONRASIB are most often described in connection with: systemic therapy, treatment adult, metastatic pancreatic, received least, one prior, usage rasonque, ras gtpase, family indicated. Wording differs between labels, and the full indications section on this page takes precedence when it is present.

After the strong CYP3A inhibitor without P-gp inhibition has been discontinued for 5 days or 3 to 5 half-lives, whichever is longer, resume the RASONQUE dosage taken prior to initiating the inhibitor. Moderate CYP3A Inhibitors with P-gp Inhibition Reduce the dosage of RASONQUE from 300 mg once daily to 100 mg once daily when used concomitantly with a moderate CYP3A inhibitor with P-gp inhibition [see Drug Interactions (7.1) ] .

Moderate CYP3A Inhibitors without P-gp Inhibition Reduce the dosage of RASONQUE from 300 mg once daily to 200 mg once daily when used concomitantly with a moderate CYP3A inhibitor without P-gp inhibition [see Drug Interactions (7.1) ] . After the moderate CYP3A inhibitor without P-gp inhibition has been discontinued for 3 to 5 half-lives, resume the RASONQUE dosage taken prior to initiating the inhibitor. P-gp Inhibitors Reduce the dosage of RASONQUE from 300 mg once daily to 150 mg once daily when used concomitantly with a P-gp inhibitor [see Drug Interactions (7.1) ] . After the P-gp inhibitor has been discontinued, resume the RASONQUE dosage taken prior to initiating the inhibitor. Strong CYP3A Inducers If a strong CYP3A inducer cannot be avoided, increase the dosage of RASONQUE from 300 mg once daily to 400 mg once daily when used concomitantly with a strong CYP3A inducer [see Drug Interactions (7.1) ] . After discontinuing use of the strong CYP3A inducer, resume RASONQUE dosage (7 to 14 days after discontinuing the strong CYP3A inducer) that was taken prior to initiating the inducer. Moderate CYP3A Inducers Increase the dosage of RASONQUE from 300 mg once daily to 400 mg once daily when used concomitantly with a moderate CYP3A inducer [see Drug Interactions (7.1) ] . After discontinuing use of the moderate CYP3A inducer, resume RASONQUE dosage (7 to 14 days after discontinuing the moderate CYP3A inducer) that was taken prior to initiating the inducer.

6 ADVERSE REACTIONS The following clinically significant adverse reactions are described elsewhere in the labeling: Dermatologic and Soft Tissue Toxicity [see Warnings and Precautions (5.1) ] Stomatitis and Oral Disorders [see Warnings and Precautions (5.2) ] Diarrhea [see Warnings and Precautions (5.3) ] Gastrointestinal Perforation [see Warnings and Precautions (5.4) ] Interstitial Lung Disease (ILD)/Pneumonitis [see Warnings and Precautions (5.5 )] Most common adverse reactions (≥ 20%) were rash, diarrhea, stomatitis, nausea, fatigue, vomiting, abdominal pain, edema, decreased appetite, and hemorrhage. ( 6.1 ) Most common laboratory abnormalities (≥ 20%) were decreased albumin, decreased calcium, decreased hemoglobin, increased aspartate aminotransferase, decreased lymphocytes, decreased platelets, increased alanine aminotransferase, decreased sodium, decreased white blood cells, decreased magnesium, increased alkaline phosphatase, increased creatinine, and decreased potassium. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Revolution Medicines, Inc. at 1-844-2-REVMED (1-844-273-8633) or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch . 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The pooled safety population of RASONQUE described in the WARNINGS AND PRECAUTIONS section reflects exposure to RASONQUE 300 mg once daily in 241 patients with pancreatic adenocarcinoma enrolled in RASolute 302 and 184 patients with pancreatic adenocarcinoma enrolled in the open-label trial RMC-6236-001. Metastatic Pancreatic Adenocarcinoma The safety of RASONQUE was evaluated in RASolute 302 [see Clinical Studies (14) ] . Patients with metastatic pancreatic adenocarcinoma received either RASONQUE 300 mg once daily (N = 241) or physician’s choice of standard of care (SOC) chemotherapy regimens (N = 214). Among patients who received RASONQUE, 52% were exposed for 6 months or longer and 2% were exposed for greater than one year. Serious adverse reactions occurred in 30% of patients treated with RASONQUE. Serious adverse reactions occurring in ≥ 2% of patients treated with RASONQUE were diarrhea (3.7%), pyrexia (3.3%), sepsis (2.9%), fatigue (2.1%), and hemorrhage (2.1%). Adverse reactions leading to permanent discontinuation of RASONQUE occurred in 2.9% of patients, including two patients who discontinued due to rash (0.8%). Adverse reactions leading to dose interruptions occurred in 69% of patients who received RASONQUE. Adverse reactions which required dose interruptions in ≥ 5% of patients were rash (27%), stomatitis (20%), fatigue (9%), diarrhea (8%), vomiting (8%), nausea (7%), and pyrexia (6%). Adverse reactions leading to dose reductions occurred in 37% of patients who received RASONQUE. Adverse reactions which required dose reductions in ≥ 5% of patients were rash (18%), stomatitis (8%), and diarrhea (5%). The most common (≥ 20%) adverse reactions in patients treated with RASONQUE were rash, diarrhea, stomatitis, nausea, fatigue, vomiting, abdominal pain, edema, decreased appetite, and hemorrhage. Table 3 and Table 4 summarize adverse reactions and laboratory abnormalities in RASolute 302, respectively.
