An open-label, first-in-human, Phase 1 study in adult patients with relapsed advanced lymphomas will be done to assess AUR108 safety, tolerability, pharmacokinetics, pharmacodynamics, and optimal biological dose.

This is a Phase I, Open Label, Dose-Escalation, First-in-Human study in adult patients with select relapsed advanced lymphomas. The safety and tolerability of oral AUR108 will be evaluated in patients with Non-Hodgkin lymphoma and Hodgkin lymphoma who do not have any available curative or life-prolonging treatment options and have exhausted all effective locally available therapies. The traditional 3+3 design for dose escalation will be used to evaluate the safety, pharmacokinetics/pharmacodynamics, and determine the Optimal Biological Dose of AUR108 as a single agent. The Optimal Biological Dose will be selected using a totality of safety, PK, and PD data.

Inclusion Criteria:

1. Males or females ≥ 18 years of age

   6. ALT (SGPT) ≤ 3 x ULN (≤ 5 × ULN if known liver metastases)
   7. Creatinine clearance (CrCl) ≥ 30 mL/min (either measured or estimated by the Cockcroft-Gault formula). (Cockcroft-Gault formula for estimated creatinine clearance [eCrCl]: eCrCl = [140- Age] × Weight [kg] × [0.85 if Female] / [72 × serum creatinine (mg/dL)]).

4. Ability to swallow and retain oral medications

5. Histo-pathological diagnosis of a Non-Hodgkin lymphoma orHodgkin Lymphoma. Note: The lymphoma should be either in Stage III or IV according to Lugano classification (Cheson BD et al, 2014) at screening.

6. In the case of subjects who have lymphoma for which high-dose chemotherapy and autologous stem cell transplantation (HDASCT) is considered a standard curative therapy, eligibility for this study requires that the subject's disease has relapsed after HDASCT, that the subject is not eligible for HD-ASCT, or that the subject has refused HD-ASCT.

7. In the case of subjects who have lymphoma for which CAR-T therapy is considered a standard therapy, eligibility for this study requires that the subjects disease has relapsed after CAR-T, or that the subject has refused CAR-T, or that the CAR-T therapy is not accessible to the patient.

8. Evidence of measurable disease as per Lugano Criteria for Lymphoma (Cheson BD et al, 2014).

9. Standard curative measures do not exist, and patient must have exhausted all effective therapies, available locally.

   1. At a minimum, the patients must have received at least 2 prior lines of systemic therapies. These systemic therapies could be either in the stage II, III or IV.
   2. Any cancer patient with access to any effective therapy must not be enrolled.

Exclusion Criteria:

1. Systemic anti-cancer therapy, such as chemotherapy, or biological therapy, immunomodulatory drug therapy, received within the past 28 days or 5 half-lives, whichever is longer, from the Cycle 1 Day 1 of the study.

   Note: Concomitant use of low dose prednisone (up to 10 mg/day) is allowed.

2. Presence of an acute or chronic toxicity resulting from prior anticancer treatment, with the exception of alopecia or nail changes, that has not resolved to Grade ≤ 1, as determined by NCI CTCAE v 5.0.

3. Definitive Radiotherapy within the last 21 days of Cycle 1 Day 1 (limited field palliative radiation is allowed and no restrictions during the screening period or during the trial).

4. Use of any investigational agent within 28 days or 5 half-lives (whichever is longer) prior to Cycle 1 Day 1.

5. Patients with cutaneous lymphomas, mycosis fungoides (MF) or Sézary syndrome (SS).

6. Primary CNS lymphoma

7. Known symptomatic or untreated or recently treated (≤ 6 months of screening) central nervous system (CNS) lymphoma. Patients with previously treated (> 6 months of screening) CNS lymphoma and are now stable and asymptomatic, from CNS perspective, are allowed

8. Patients with lymphoma that requires immediate cytoreductive therapy

9. Patients with lymphoma that requires immediate cytoreductive therapy

10. Patients on the drugs which are sensitive substrates of CYP2C8 and cannot be discontinued at least one week prior to Cycle 1 Day 1

11. Patients on the drugs which are sensitive substrates of either Poglycoprotein (P-gp) or breast cancer resistance protein (BCRP) and cannot be discontinued at least one week prior to Cycle 1 Day 1

12. Major surgery ≤ 28 days from Cycle 1 Day 1 (major surgery is defined as a procedure requiring general anesthesia)

13. Active infection requiring systemic therapy. Note: Prophylactic use of antibiotics is allowed. Any infection detected during screening period which is resolved adequately according to investigator before the Cycle 1 Day 1, is allowed.
