•decline standard therapy.
2.Prior MKIs with anti-RET activity are allowed.
3.A RET gene alteration is not required initially. Once adequate PK exposure is achieved, evidence of RET gene alteration in tumor and/or blood is required
4.Measurable or non-measurable disease as determined by RECIST 1.1 or RANO as appropriate to tumor type.

7.Life expectancy of at least 3 months.
8.Archived tumor tissue sample available.
9.Adequate hematologic status, defined as:
•Absolute neutrophil count (ANC) ≥ 1.0.10^9/L not requiring growth factor support for at least 7 days prior to treatment, and
•Platelet count ≥ 75.10^9/L not requiring transfusion support for at least 7 days prior to treatment, and
•Hb ≥ 9 g/dL not requiring transfusion support or erythropoietin for at least 7 days prior to treatment.
10.Adequate hepatic function, defined as:
•ALT and AST ≤ 2.5 ULN or ≤ 5 ULN with documented liver involvement (such as liver metastasis or a primary biliary tumor); and
•Total bilirubin ≤ 1.5 ULN or ≤ 3 ULN with documented liver involvement (patients with Gilbert’s Disease may be enrolled with prior Sponsor approval).
11.Adequate renal function, with estimated glomerular filtration rate ≥ 30 mL/minute (up to 6 patients with an estimated glomerular filtration rate (eGFR) ≥ 15 and < 30 will be allowed to enroll with Sponsor approval).

Phase 2
As for phase 1 with the following modifications:
1.Cohorts 1 and 3: failed or intolerant to standard of care. Cohorts 2 and 4 without prior standard first line therapy.
2.Cohorts 1-4: enrollment will be restricted to patients with evidence of a RET gene alteration in tumor (i.e., not just blood) as defined in Table 3 3. However, a positive germline DNA test for a RET gene mutation as defined in Table 3 3 is acceptable in the absence of tumor tissue testing for patients with MTC.
3.Cohorts 1-4: at least one measurable lesion as defined by RECIST 1.1 or RANO, as appropriate to tumor type and not previously irradiated (unless PD for the irradiated lesion[s] has been radiographically documented).
4.Cohort 4: radiographic PD within the previous 14 months.
5. Cohort 6: Patients who otherwise are eligible for Cohorts 1-5 who discontinued another RET inhibitor may be eligible with prior Sponsor approval.
Note: Examples of RET inhibitors may include TPX0046, pralsetinib (BLU-667), or BOS172739.
6. Cohort 5: Patients who otherwise are eligible for:
• Cohorts 1-4 without measurable disease;
• MTC not meeting the requirements for Cohorts 3 or 4;
• MTC syndrome spectrum cancers (e.g., MTC, pheochromocytoma), cancers with neuroendocrine features/differentiation, or poorly differentiated thyroid cancers with other RET alteration/activation may be allowed with prior Sponsor approval;
• cfDNA positive for a RET gene alteration not known to be present in a tumor sample.

| E.4 | Principal exclusion criteria |
1.Phase 2 Cohorts 1-4: an additional validated oncogenic driver that could cause resistance to selpercatinib treatment. See Appendix C (Table 11 3) for examples.
