Dexrazoxane is a cardioprotective drug used in patients with breast cancer to reduce cardiomyopathy associated with doxorubicin administration. Dexrazoxane is believed to act by two mechanisms: it inhibits DNA topoisomerase II and acts as a chelator for iron ions.

Aldoxorubicin (INNO-206) is a tumor-targeted doxorubicin conjugate developed by CytRx for treating relapsed and refractory sarcomas, especially L-sarcomas. Aldoxorubicin is a rationally-engineered cytotoxic which delivers a well-established anti-cancer agent, doxorubicin, into the tumor. Currently, in late-stage clinical trials, Aldoxorubicin appears to overcome the key limitations of doxorubicin, including cumulative dose restrictions. Aldoxorubicin utilizes an acid-sensitive linker that selectively binds to albumin, which may allow the cytotoxic payload to preferentially accumulate in the tumor and potentially spare the surrounding healthy tissue. This mechanism leverages the tumor's low pH environment and accompanying dependency upon circulating albumin to fuel growth, to enable the delivery of multifold times the standard dosing of doxorubicin. The preferential uptake of Aldoxorubicin by tumor tissue and the acid sensitive release of doxorubicin allow for Aldoxorubicin to be a very promising anticancer agent. In phase I and II trials, Aldoxorubicin demonstrates superior efficacy over doxorubicin. Although the studies were not powered for OS, Aldoxorubicin shows improved PFS and tumor response in comparison to doxorubicin. The safety profile was also comparable to that of doxorubicin. Similarly, results from the recent phase III study showed a benefit in PFS in the leiomyosarcoma subtypes.

3-[(4-Methyl-1-piperazinyl)carbonyl]-7-oxabicyclo[2.2.1]heptane-2-carboxylic acid (LB-100) is an experimental cancer therapeutic with cytotoxic activity against cancer cells in culture and antitumor activity in animals. It is an intravenously administered, small-molecule, serine-threonine protein phosphatase (PP2A) inhibitor, being developed by Lixte Biotechnology Holdings. LB-100 delivers an active metabolite into the cell, potently inhibiting specifically the s/t ptases PP2A. Inhibition of PP2A markedly potentiates the effectiveness of standard anti-cancer drugs and X-ray that exert their clinical benefit by damaging DNA thereby inhibiting faithful cell division. Although the growth of normal cells including those of the bone marrow, GI tract, and hair is also impaired by cytotoxic cancer treatment, cancer cells often have acquired genetic damage that permits their unrestrained growth but also reduces their ability to repair DNA damage. Inhibition of PP2A by LB-100 further impairs DNA repair to a greater extent in the cancer cell than in the normal cell providing more selective killing. LB-100 used alone has modest inhibitory activity against many cancers in model systems, but certain human cancers, possessing unique genetic changes in addition to those reducing DNA damage repair, are particularly vulnerable to inhibition of PP2A by LB-100. Among these is myelodysplastic syndrome (MDS), an increasingly common neoplastic disease, especially in persons aged 65 and older, characterized by failure of the bone marrow. In particular, a variant of MDS termed del(5q)MDS is missing ~50% of its PP2A activity rendering this tumor potentially vulnerable to further pharmacologic inhibition of PP2A
