Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
(Part 1 enrollment complete) In the initial stage of the trial (36 participants), two dose levels of SM-88's metyrosine-derivative was evaluated.
(Part 2 actively enrolling) The second part will consist of a subsequent expansion of the trial to further assess safety and efficacy of SM-88 used with MPS containing the selected SM-88 RP2D from Part 1. A total of 250 participants in the second part will be randomized 1:1 either to the SM-88 arm (125 participants) or Physician's Choice of therapy for the Control Arm (125 participants). Participants should have previously received two lines of prior systemic therapy.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
Part 1
Biopsy-proven metastatic pancreatic adenocarcinoma with documented radiographic disease progression on or after one or more systemic therapies. Chemotherapy given as part of prior chemoradiation in the setting of non-metastatic pancreatic cancer does not count as a line of therapy. Chemotherapy given for at least 4 months as adjuvant after complete response is considered as a first line therapy.
Part 2
Biopsy-proven metastatic pancreatic adenocarcinoma on or after two prior lines of systemic therapy. Chemotherapy given as part of prior chemo- radiation in the setting of non-metastatic pancreatic cancer does not count as a line of therapy unless metastases develop within 6 months of completing the chemo sensitization. Chemotherapy given for at least 4 months as adjuvant after a CR to any therapy (e.g. surgery and radiation therapy) is also considered as a first line therapy. Of the two prior lines, participants should have received a gemcitabine-based regimen for a prior line and a 5-FU based regimen as a prior line of therapy. Investigational therapies as part of a prior line regimen are permitted.

16. History of any known drug allergies to any study medication.
17. Are currently enrolled in, or have discontinued within 14 days of screening, from a clinical trial involving an investigational product or non-approved use of a drug or device.

26. Participants with a hypersensitivity to sirolimus.
27. Participants with a history of the light sensitive diseases for which methoxsalen would be contraindicated. Diseases associated with photosensitivity include lupus erythematosus, porphyria cutanea tarda, erythropoietic protoporphyria, variegate porphyria, xeroderma pigmentosum, and albinism.
28. Participants treated, or anticipated to be treated, with delavirdine (due to potential for loss of virologic response and possible resistance to delavirdine or to the class of non-nucleoside reverse transcriptase inhibitors caused by phenytoin).
29. Participants with cutaneous melanoma or invasive squamous cell carcinomas or a history thereof, except for those in complete remission for ≥5 years (due to contraindication for use of methoxsalen).
30. Participants with prior organ transplant or being treated, or anticipated to be treated, with cyclosporine (because long-term administration of the combination of cyclosporine and sirolimus is associated with deterioration of renal function).
31. Participants with a seizure disorder that is not well controlled or who have required a change in seizure medications within 60 days of enrollment to the trial.
32. Participants treated, or anticipated to be treated, with a calcineurin inhibitor (because concomitant use of sirolimus and a calcineurin inhibitor increases the risk of calcineurin inhibitor-induced hemolytic uremic syndrome/thrombotic thrombocytopenic purpura/thrombotic microangiopathy \[HUS/TTP/TMA\]).
33. Participants with interstitial lung disease (ILD) \[including pneumonitis, bronchiolitis obliterans organizing pneumonia (BOOP), and pulmonary fibrosis\].

36. Clinically significant cataracts or aphakia.
37. Presence of ascites or pleural effusion.
