FOUNDAYO is contraindicated in patients with: A personal or family history of MTC or in patients with MEN 2 [see Warnings and Precautions ( 5.1 )] . Known serious hypersensitivity to orforglipron or any of the excipients in FOUNDAYO. Serious hypersensitivity reactions, including anaphylaxis and angioedema, have been reported with GLP-1 receptor agonists [see Warnings and Precautions ( 5.6 ), Adverse Reactions ( 6.2 )] . Personal or family history of MTC or in patients with MEN 2 ( 4 ) Known serious hypersensitivity to orforglipron or any of the excipients in FOUNDAYO ( 4 )

Strong CYP3A4 Inhibitors: The maximum dosage of FOUNDAYO is 9 mg once daily when used concomitantly with a strong CYP3A4 inhibitor. Avoid concomitant use with strong CYP3A4 inhibitors that also inhibit OATP1B. ( 7.1 ) CYP3A4 Inducers: Avoid concomitant use with strong CYP3A4 inducers. Monitor FOUNDAYO effectiveness and escalate dosage as needed when used concomitantly with moderate CYP3A4 inducers. ( 7.1 ) Simvastatin: Do not exceed simvastatin 20 mg once daily when used concomitantly with FOUNDAYO. ( 7.2 ) FOUNDAYO delays gastric emptying and has the potential to impact the absorption of concomitantly administered oral medications. ( 7.3 ) 7.1 Effect of Other Drugs on FOUNDAYO Table 2 includes clinically relevant interactions where concomitant use of other drugs affects FOUNDAYO. Table 2: Clinically Relevant Effects of Other Drugs on FOUNDAYO Strong CYP3A4 Inhibitors Intervention The maximum dosage of FOUNDAYO is 9 mg once daily when used concomitantly with a strong CYP3A4 inhibitor. Avoid concomitant use of FOUNDAYO with strong CYP3A4 inhibitors that also inhibit OATP1B (e.g., ritonavir) [see Dosage and Administration ( 2.2 )] . Clinical Impact CYP3A4 inhibitors increase FOUNDAYO exposure [see Clinical Pharmacology ( 12.3 )] , which may increase the risk of FOUNDAYO-associated adverse reactions. Strong CYP3A4 inhibitors that also clinically inhibit OATP1B are expected to significantly increase plasma concentrations of FOUNDAYO, which may increase the risk of FOUNDAYO-associated adverse reactions [see Warnings and Precautions ( 5.3 ), Adverse Reactions ( 6.1 )] . Strong CYP3A4 Inducers Intervention Avoid concomitant use of FOUNDAYO with strong CYP3A4 inducers. Clinical Impact Induction of CYP3A4 decreases FOUNDAYO exposure [see Clinical Pharmacology ( 12.3 )] , which may reduce the effectiveness of FOUNDAYO. Moderate CYP3A4 Inducers Intervention Monitor FOUNDAYO effectiveness and escalate dosage as needed when used concomitantly with moderate CYP3A4 inducers [see Dosage and Administration ( 2.1 )] . Clinical Impact Induction of CYP3A4 decreases FOUNDAYO exposure [see Clinical Pharmacology ( 12.3 )] , which may reduce the effectiveness of FOUNDAYO. 7.2 Effect of FOUNDAYO on Other Drugs Table 3 includes clinically relevant interactions where concomitant use of FOUNDAYO affects other drugs. Table 3: Clinically Relevant Effects of FOUNDAYO on Other Drugs Simvastatin Intervention Do not exceed simvastatin 20 mg once daily when concomitantly used with FOUNDAYO. Clinical Impact Use of FOUNDAYO with simvastatin increased exposure of the active metabolite simvastatin acid two-fold [see Clinical Pharmacology ( 12.3 )] . A two-fold increase in simvastatin acid exposure at the highest simvastatin dose could be clinically meaningful. Insulin or Insulin Secretagogue (e.g., Sulfonylurea) Intervention When initiating FOUNDAYO, consider reducing the dose of concomitantly administered insulin or insulin secretagogues (e.g., sulfonylureas) [see Warnings and Precautions ( 5.5 )] . Clinical Impact FOUNDAYO stimulates insulin release in the presence of elevated blood glucose concentrations which could increase the risk for hypoglycemia when used in combination with insulin or insulin secretagogues. 7.3 Effect of FOUNDAYO on Oral Medications FOUNDAYO delays gastric emptying and thereby has the potential to impact the absorption of concomitantly administered oral medications [see Clinical Pharmacology ( 12.3 )] . Advise patients using oral hormonal contraceptives to switch to a non-oral contraceptive method or add a barrier method of contraception for 30 days after initiation with FOUNDAYO and for 30 days after each dose escalation. Hormonal contraceptives that are not administered orally should not be affected.
