Overview

This is a multicenter, open-label, Phase 1 study of AUR104 in adult patients with select Relapsed/Refractory (R/R) Lymphoid Malignancies. The main objective of the study is to evaluate the safety and tolerability of the study drug AUR104.In this study, safety, tolerability, pharmacokinetics, pharmacodynamics, and efficacy of AUR104 will be evaluated in dose escalation manner.

   Note

5a. The lymphoma should be either in Stage III or IV according to Lugano classification at screening.

5b. The lymphomas included in this study must fall within one of the following 2017 World Health Organization categories except lymphoma mentioned in Exclusion criterion #5:

• Mature B-cell neoplasms (excluding plasma cell neoplasms, heavy chain disease, and primary central nervous system [CNS] lymphoma).
• Mature T- and NK-cell neoplasms.
• Hodgkin lymphomas. 5c. The CLL should be Binet Stage C/Rai stage III or IV, as per the International Workshop on Chronic Lymphocytic Leukemia (iwCLL) guidelines. 6) In the case of patients who have lymphoid malignancies for which high-dose chemotherapy and autologous stem cell transplantation (HD-ASCT) is considered standard curative therapy, eligibility for this study requires that the disease has relapsed after HD-ASCT, or the subject is not eligible for HD-ASCT, or the subject has refused HD-ASCT. 7) In the case of patients who have lymphoid malignancies for which CAR-T therapy is indicated, eligibility for this study requires that the disease has relapsed after CAR-T, or the patient is not eligible for CAR-T, or the patient has refused CAR-T, or the CAR-T is not available locally. 8) Evidence of measurable disease as per Lugano Criteria for Lymphoma or evidence of measurable disease as per iwCLL Criteria for CLL.

Note: Patients with Small Lymphocytic Lymphoma (SLL) alone or in combination with CLL are allowed.

9) Standard curative measures do not exist, and the patient must have exhausted all effective therapies available locally. At a minimum, the patients must have relapsed or refractory disease to at least 2 prior lines of systemic therapies for NHL or CLL, or Hodgkin's disease.

Note: Any cancer patient with access to any effective therapy locally must not be enrolled.

Exclusion Criteria:

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

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

2. Presence of acute or chronic toxicity resulting from prior anti-cancer treatment, except for alopecia or nail changes that have 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 Burkitt's lymphoma, Burkitt-like lymphoma, post-transplant lymphoproliferative disease, primary mediastinal large-B cell lymphoma, cutaneous lymphomas, mycosis fungoides (MF), or Sezary syndrome (SS).
6. Known symptomatic or untreated or recently treated (≤ 6 months of screening) central nervous system (CNS) lymphoma. Patients with previously treated (more than 6 months of screening) CNS lymphoma and are now stable and asymptomatic, from a CNS perspective, are allowed.
7. Patients with lymphoma requiring immediate cytoreductive therapy.
8. Patients with low-grade or indolent lymphoma not meeting conventional criteria for treatment.
