Disease evaluation must be completed within 8 weeks of study entry. If possible, the disease evaluation should take place subsequent to any intervening therapy; if intervening therapy does occur, evaluations should be done as clinically indicated. If patient has received prior treatment with MIBG, they must have a response or stable disease after the most recent MIBG infusion. Patient may have PD after showing an initial response to MIBG therapy (at [or around] the day 35-63 post-MIBG therapy evaluation). 4.

If no stem cells are available, then the dose of 131I-MIBG should be <12 mCi/kg. 5. Prior Therapy: Patients may enter this study with or without re-induction therapy for recurrent tumor. Patients must have fully recovered from the toxic effects of any prior therapy, meeting the following criteria: 1. At least 2 weeks should have elapsed since any anti-tumor therapy and the patient must meet certain hematologic criteria. 2. 3 months should have elapsed in the case of completing external beam radiation for total abdominal, whole lung, total body irradiation (spot irradiation to skull-based metastases is NOT a contraindication). Patients who receive localized emergency radiation to sites of life-threatening or function-threatening disease prior to or immediately after establishment of the definitive diagnosis are not contraindicated for treatment on this protocol. 3. Cytokine therapy (e.g. G-CSF, GM-CSF, IL-6, erythropoietin) must be discontinued a minimum of 24 hours prior to 131I-MIBG therapy. 4. Minimum of six weeks from previous 131I-MIBG therapy. 5.

If the stem cell reinfusion was protocol driven but not based upon the development of profound cytopenias (e.g. automatic stem cell reinfusion on Day 14), the patient is eligible for retreatment with MIBG at a dose <12 mCi/kg at the investigators discretion; ii. If the stem cell reinfusion was given based upon the development of profound cytopenias, decisions for re-treatment with 131I-MIBG will require a case-by-case evaluation by the Investigator. 6. Organ Function: 1. Liver function: Bilirubin ≤ 2x upper limit of normal; AST/ALT ≤ 10x upper limit of normal. 2. Kidney function: i.

Patients eligible for the Phase II (OPTIMUM) trial. 3. Patients with disease of any major organ system that would compromise their ability to withstand therapy. Any significant organ impairment should be discussed with the Principal Investigator prior to patient entry. 4. Because of the teratogenic potential of the study medications, no patients who are pregnant or lactating will be allowed. Patients of childbearing potential, who are sexually active, must practice an effective method of birth control while participating on this study, to avoid possible damage to the fetus . [e.g. intrauterine device, double-barrier method (i.e., diaphragm, or a cervical cap) with intravaginal spermicidal foam, cream or gel], or male partner sterilization throughout the study]. 5. Patients who are on hemodialysis 6. Proteinuria, in the absence of urinary infection, within 4 weeks prior to the planned treatment date is a relative contraindication to receiving therapy for patients with pheochromocytoma/paraganglioma. Patients with pheochromocytoma/paraganglioma with any clinically significant proteinuria must have a 24-hr urine protein determination. If proteinuria is confirmed as being above the institutional upper limit of normal, the patient is ineligible for MIBG therapy. 7.

• Patients must have histologically confirmed mantle cell lymphoma, with cyclin D1 by immunohistochemical stains and/or t(11;14) by cytogenetics or FISH. If patient has cyclin D1 negative mantle cell lymphoma with classical morphology and an expression profile (including SOX11+) that is otherwise indistinguishable from mantle cell lymphoma, communication with investigator is required for consideration of enrollment. The proliferation rate, using Ki-67 or MIB-1, should also be determined, but is not required until Step 1 registration. Patients may register to Step 0 without a documented Ki-67 index.
• Patients should be deemed to be potentially eligible and willing candidates for auto-HCT by the enrolling physician
• Patient may be receiving or have completed induction therapy within 60 days prior to preregistration to step 0; no more than 300 days may have passed between the first day of induction therapy and preregistration to step 0

• Use caution with other substrates of CYP3A4/5, CYP1A2, CYP2B6 and substrates of P-gp, BCRP, OCT1, OATP1B1, and OATP1B3 with a narrow therapeutic index. Close monitoring is advised
• Because the lists of these agents are constantly changing, it is important to regularly consult a frequently-updated medical reference. As part of the enrollment/informed consent procedures, the patient will be counseled on the risk of interactions with other agents, and what to do if new medications need to be prescribed or if the patient is considering a new over-the-counter medicine or herbal product. Patient Drug Interactions Handout and Wallet Card) should be provided to patients
• Patients who cannot discontinue concomitant proton-pump inhibitors (PPIs). Patients may confer with the study doctor to determine if such medications can be discontinued. These must be discontinued >= 5 days prior to study treatment. Patients do not need to discontinue calcium carbonate
• Patients receiving sorivudine or any chemically related analogues (such as brivudine) are excluded
• Patients who have received a live attenuated vaccine within 30 days of dosing with peposertib (M3814)
• Patients with uncontrolled intercurrent illness, including but not limited to ongoing or active infection
• Patients with psychiatric illness/social situations that would limit compliance with study requirements
• Pregnant women are excluded from this study because peposertib (M3814) is DNA-PK inhibitor agent with the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with peposertib (M3814), breastfeeding should be discontinued if the mother is treated with peposertib (M3814). These potential risks may also apply to other agents used in this study
