Although toxicities exceeding expectations have been observed with Rova-T, drugs targeting TROP-2 (Sacituzumab Govitecan), B7-H3 (DS-7300), and SEZ6 (ABBV-011) have shown exciting clinical benefits. In this review, we collect the latest clinical evidence to describe the therapeutic efficacy and safety of ADCs in SCLC and discuss prospects and challenges.

Overall, 73.1% (49/67) of cervical cancer samples are CD138-positive with 38.8% (26/67) of cervical cancer samples showing at least moderate or high expression. (4) TROP2, CEACAM5 or CD138 do seem suitable for further clinical research and the data presented here might be used to guide further clinical trials with ADCs in advanced and recurrent cervical cancer patients.

Ranking based on expression levels and comparison to expression in normal MRC-5 fibroblasts and myoblasts, followed by statistical analysis, highlighted known RMS targets such as FGFR4, NCAM1, and CD276/B7-H3, and revealed AGRL2, JAM3, MEGF10, GPC4, CADM2, as potential targets for immunotherapies of RMS. L1CAM expression was investigated in RMS tissues, and strong L1CAM expression was observed in more than 80% of alveolar RMS tumors, making it a practicable target for antibody-based therapies of alveolar RMS.

Review of diagnostic genomic profile mid induction showed a BCR::ABL minor breakpoint fusion as well as CBF::GLIS fusion.The child began AML induction on COG AAML1831 trial randomized to the experimental arm with CPX-351 and gemtuzumab ozogamicin (GO). Due to lack of response to AML therapy at end of Induction (EOI) I, she was taken off protocol and started on modified ALL regimen for Induction II consisting of cytarabine, low dose weekly methotrexate and bimonthly peg-asparaginase with addition of an oral TKI, dasatinib...Given availability of FOLR1 directed ADC on single-patient compassionate use basis, patient received single agent STRO-001 on a bi-monthly basis...Long-term follow-up is required to assess durability of remission. Additional testing of this approach in a larger patient population is needed to determine the role of STRO-002 in this high-risk pediatric AML population.

Antibody-drug conjugates (ADCs) are rapidly establishing their place and have shown promising preliminary data in lung cancer with impressive response rates and survival outcomes in previously treated patients.There are several ADCs currently in clinical trials for NSCLC and small cell lung cancer (SCLC). These ADCs often have different targets which include HER2, HER3, TROP2, CEACAM5, and MET in NSCLC and DLL3 in SCLC.Here we review the safety, and efficacy of newer ADCs in lung cancer including ado-trastuzumab emtansine, trastuzumab deruxetecan, patritomab deruxetecan, datopotamab deruxetecan, sacituzumab govitecan, SAR408701, Telisotuzumab vedotin, rovalpituzumab tesirine, lorvotuzumab mertansine, and sacituzumab govitecan.  Several novel methods are underway to improve the safety and efficacy of ADCs which include increasing the drug to antibody ratio (DAR), the potency of the payload, using more innovative payloads and replacing the antibody.

Our study suggests Adcitmer® as a therapeutic option to be further assessed in MCC patients, as an alternative or combined with immune checkpoint inhibitors.

Adcitmer significantly reduced tumor growth in a MCC mouse model. Our study suggests Adcitmer as a therapeutic option to be further assessed in MCC patients, as an alternative or combined with immune checkpoint inhibitors.

Belantamab mafodotin, a B-cell maturation antigen (BCMA)-targeted ADC, has shown response rates >30% in a phase 2 trial of highly refractory patients and is being investigated in a variety of settings and combinations...This is an area of active preclinical research at this time. Lastly, designed ankyrin repeat proteins, which are small antibody-mimetic proteins with high target-binding affinity, have the potential to block multiple pathways at once and provide stimulatory signals to the immune system.

While Treg modulation was seen with all populations, these data support further study, particularly of the Cami 45 µg/kg dose for pts with HL. Given that CD25 is the cognate target of Cami, these data suggest pts with HL achieving CR have higher drug exposure, resulting from lower baseline sCD25, and potential association with lower tumor burden. Although exposure at the 45 µg/kg dose showed moderate inter-patient variability, it was associated with noteworthy, cycle-related modulation in circulating Treg and clear increases in Teff:Treg ratios, thought to favor clinical response.

Future expansion of this methodology into other cellular therapies (CAR NK or BiTE) and the examination of new data sources could reveal additional targets with robust expression in AML. Demonstration of cell surface expression of these targets, and appropriate preclinical evidence of efficacy, could lay the groundwork for quickly moving these therapies to clinical trials in AML.

Lorvotuzumab mertansine (110 mg/m ) is tolerated in children at the adult recommended phase 2 dose; clinical activity is limited.
