Inclusion Criteria:

* Histologically or cytologically confirmed diagnosis of locally advanced, unresectable (Stage IIIB, IIIC), or metastatic Stage IV (M1a, M1b, or M1c) NSCLC American Joint Committee on Cancer (AJCC) Staging Manual, Version 8.0, and the Union for International Cancer Control (UICC) Staging System (Eighth edition).
* Participants must have NSCLC with nonsquamous histology

  * Tumors with squamous, or predominantly squamous histology are excluded.
  * Tumors with small cell elements are excluded.
* Participants who have NSCLC with known actionable genomic alteration (AGAs) are permitted
* Participants must have received the following prior therapies and progressed during or relapsed after receiving their most recent prior therapy:

  * Participants with no known AGAs must fulfill 1 of the following conditions:

    * Received a platinum-based combination therapy for the treatment of metastatic or recurrent disease and a PD-(L)1 monoclonal antibody (concurrently or sequentially with platinum-based chemotherapy), unless contraindicated.
    * Experienced disease progression within 6 months of the last dose of platinum-based chemotherapy in the adjuvant or neoadjuvant setting and received a PD-(L)1 monoclonal antibody at any time during the course of treatment.
  * Participants with known AGAs must fulfill the following conditions:

    * Must have received at least 1 relevant AGA targeted therapy and in the opinion of the investigator, additional AGA targeted therapy is not in the best interest of the participant.
    * Received a platinum-based combination therapy for the treatment of metastatic or recurrent disease, or experienced disease progression within 6 months of the last dose of platinum-based chemotherapy in the adjuvant or neoadjuvant setting
    * May have received up to 1 PD-(L)1 monoclonal antibody (concurrently or sequentially with platinum-based chemotherapy).
* Measurable disease based on RECIST v1.1

* History of another malignancy within 3 years before Cycle 1 Day 1, or any evidence of residual disease from a previously diagnosed malignancy. Exceptions are malignancies with a negligible risk of metastasis or death
* Participants with any of the following respiratory conditions:

  * Evidence of noninfectious interstitial lung disease (ILD) or pneumonitis that:

    * Was previous diagnosed and required systemic steroids, or
    * Is currently diagnosed and managed, or
    * Is suspected on radiologic imaging at screening
  * Known diffusing capacity of the lung for carbon monoxide (DLCO) < 50%
  * Any Grade greater than or equal to (≥) 3 pulmonary disease unrelated to underlying malignancy
* Pre-existing peripheral neuropathy Grade greater than or equal to (≥) 2
* Uncontrolled diabetes mellitus
* Prior therapy:

  * Prior treatment with antimicrotubule agents (taxanes, vinca alkaloids, or MMAEs) in the locally advanced, unresectable/refractory, or metastatic setting
  * Prior antimicrotubule agent exposure in curative settings (including adjuvant, neoadjuvant, or chemoradiotherapy) is permissible.
  * Received more than 1 prior line of cytotoxic chemotherapy in the locally advanced, unresectable/refractory, or metastatic setting
  * Prior cytotoxic chemotherapy in curative settings is permissible
  * At least 14 days must have elapsed from the last dose of radiotherapy until Cycle 1 Day 1.
  * Prior radiation therapy to the lung parenchyma that is >30 Gray (Gy) within 6 months of Cycle 1 Day 1.
  * Any systemic anticancer therapy (standard or experimental) within 21 days prior to Cycle 1 Day 1.
* Active central nervous system (CNS) lesions, including leptomeningeal metastasis, are excluded. Participants with definitively treated brain metastases are eligible in they meet the following criteria:

  * Have been clinically stable for at least 4 weeks prior to treatment initiation and baseline scans show no evidence of new or enlarged metastasis

  * Treatment with corticosteroids greater than (>) 1 month prior to Screening visit
  * No evidence of clinical and radiographic disease progression in the CNS for ≥ 21 days after definitive radiotherapy and/or surgery
