NCCN guidelines recommend systemic therapy after first-line failure of a RET-specific TKI for RET rearrangement–positive adenocarcinoma. If there are no contraindications to PD-1 or PD-L1 inhibitors, preferred category 1 regimens for second-line treatment are pembrolizumab/carboplatin/pemetrexed or pembrolizumab/cisplatin/pemetrexed.

Other recommended category 1 second-line regimens are atezolizumab/carboplatin/paclitaxel/bevacizumab or nivolumab/ipilimumab/pemetrexed/(carboplatin or cisplatin).

After treatment failure with a RET-specific TKI, another drug in the same class may not be used in subsequent therapy.
