Anish Thomas, MBBS, M.D.

I am a clinical researcher with a focus on small cell lung cancer (SCLC), one of the most aggressive human cancers. The goal of my research is to systematically develop more effective therapies for patients with SCLC and similar chemotherapy-refractory tumors by targeting key pathways involved in DNA replication, repair, and chromatin remodeling. I design and conduct phase I and phase II trials that examine strategies to determine how enhancing DNA replicative stress can best be used in the clinic in combination with existing therapies to improve patient outcomes. This work stems from my intramural and extramural collaborations with basic scientists, translational researchers, surgical pathologists and clinicians, all of whom are interested in various facets of SCLC- from understanding the biology of genomic instability, chromatin regulation, and immunomodulation in solid tumors to identifying cancer dependencies that drive responses.
1) small cell lung cancer, 2) DNA damage response, 3) immune response, 4) genomic instability, 5) chromatin regulation, 6) immunotherapy

Our primary hypothesis is that a rational use of DNA damage response inhibitors can enhance replicative stress and augment efficacy of currently available therapies including chemotherapies and immunotherapies. The secondary hypothesis is that tumor targeted chemotherapy delivery could improve the tolerability of DNA damage response inhibitor-combinations. We now have 5 ongoing trials addressing these hypotheses. Our first trial, a phase I trial of an ATR kinase inhibitor and topotecan recently completed enrolment and we are now enrolling patients on phase II. Other ongoing trials involve combinations of PARP inhibitors with tumor targeted chemotherapy or immunotherapy.
The following trials are recruiting small cell cancer patients:
- A Phase II Trial of Topotecan plus VX970, an ATR Kinase Inhibitor (open also for extra-pulmonary small cell cancers)
- A phase II Trial of anti-PDL1 antibody durvalumab plus olaparib (SCLC cohort)
- A Phase I/II Trial of CRLX101, a Nanoparticle Camptothecin with Olaparib in Patients with Relapsed/Refractory Small Cell Lung, Bladder and Prostate Cancers
The following trials are recruiting solid tumor patients who have previously been treated with chemotherapy:
- Phase I Study of a Combination of MM-398 and Veliparib in solid tumors
- A Phase I/II Trial of CRLX101, a Nanoparticle Camptothecin with Olaparib in Patients with Relapsed/Refractory Small Cell Lung, Bladder and Prostate Cancers
- The first-in-human phase I trial of PEN-866, PEN-866 in Patients With Advanced Solid Malignancies
